$1000 is 71.43 percent of the credit limit.
To lower the debt to credit limit ratio by $1000, you have a few options. The first option is to increase your credit limit by requesting a higher limit from your credit card issuer. Alternatively, you can pay off some of your outstanding balance to reduce your debt. Either way, it's important to make sure you're not maxing out your credit limit, as this can negatively impact your credit score.
It's also a good idea to review your spending habits and create a budget to ensure you're not overspending and accumulating debt. By making responsible financial decisions and managing your credit wisely, you can improve your credit score and achieve your financial goals.
To calculate the percentage of $1000 in terms of the credit limit of $1400, we need to divide $1000 by $1400 and multiply the result by 100. This gives us,
($1000 / $1400) x 100 = 71.43%
Therefore, $1000 is approximately 71.43% of the credit limit of $1400.

The constant of proportionality is $8.40
What is constant of proportionality?The constant of proportionality is a value that relates two quantities that are proportional to each other. It is represented by the letter k and is found by dividing the dependent variable by the independent variable. In this case, the constant of proportionality is $8.40 for the given data set.
According to the given information:
To find the constant of proportionality, we can use any two data points from the table and plug them into the equation y = kx.
Let's use the first and second data points: (0.75, $6.30) and (2.5, $21.00).
We can set up the equation as:
$6.30 = k(0.75)
Solving for k, we get:
k = $6.30/0.75 = $8.40
Now, we can check our work by using another data point. Let's use the third data point: (4, $33.60).
Plugging in the values, we get:
$33.60 = k(4)
k = $33.60/4 = $8.40
Since we get the same value for k, we can be confident that our answer is correct.
Therefore, the constant of proportionality is $8.40.

Mrs. Hallmark wants to sell a box of two varieties of
birthday cards for $5. 80. The number of 30¢ cards is six
more than one half the number of 35¢ cards. The number
of 35¢ cards is:
According to unitary method, there are 10 30¢ cards and 8 35¢ cards in the box, which adds up to a total of $5.80.
Let's start by defining our units. In this case, our units are the number of 30¢ cards and the number of 35¢ cards. We know that the box of cards is being sold for $5.80, which means the total value of all the cards in the box is $5.80. We can use this information to set up an equation:
0.30x + 0.35y = 5.80
where x is the number of 30¢ cards and y is the number of 35¢ cards.
Next, we are given the information that the number of 30¢ cards is six more than one half the number of 35¢ cards. Using the unitary method, we can set up an equation that relates the number of 30¢ cards to the number of 35¢ cards:
x = 0.5y + 6
Now we can use this equation to eliminate x from our first equation:
0.30(0.5y + 6) + 0.35y = 5.80
Simplifying this equation gives:
0.15y + 1.80 + 0.35y = 5.80
0.50y = 4.00
y = 8
So there are 8 35¢ cards in the box. We can use the unitary method again to find the number of 30¢ cards:
x = 0.5y + 6
x = 0.5(8) + 6
x = 10

What is the value of n?
The equation (5 x 10⁶) (9 × 10⁻²) = 6 x 10⁴ when written in scientific notation. The value of b is 5 and the value of n is 4.
What is scientific notation?Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in standard decimal form. The number is written in the form of a number between 1 and 10 multiplied by a power of 10.
The value of b in this equation is 5. This is because the decimal points in both terms must be aligned in order to multiply them together.
The decimal points in each term are 6 and 2, respectively.
Since 6 is greater than 2, the decimal point for the total must be aligned with 6.
This means that the number 5 must be multiplied by 10⁶, resulting in b being 5.
The value of n in this equation is 4. This is because when the two terms are multiplied together, the exponents must be added.
The exponents of 10 in each term are 6 and -2, respectively.
When these are added together, they equal 4, resulting in the exponent of 10 in the new term to be 4.
Therefore, the equation (5 x 10⁶) (9 × 10⁻²) = 6 x 10⁴ when written in scientific notation. The value of b is 5 and the value of n is 4.

D. Taylor could find the ratio of the area of the square with side length a + b to the area of the square with side length c.
If Taylor is proving the Pythagorean theorem. Taylor can use the diagram to prove the Pythagorean theorem by: A. Taylor could set the area of a square with side length a + b equal to the sum of the areas of the 4 triangles and the square with side length c.
How could Taylor use the diagram to prove the Pythagorean theorem?To prove the Pythagorean theorem, we want to show that in a right triangle with legs a and b and hypotenuse c, the square of the hypotenuse c^2 is equal to the sum of the squares of the legs a^2 + b^2.
From the given diagram, we can see that we have a square with side length a+b, which is divided into 4 congruent right triangles and a smaller square with side length c. Each of the 4 triangles has legs a and b, which are also the legs of the right triangle we want to prove the theorem for. The smaller square with side length c has an area equal to c^2, which is the square of the hypotenuse of the right triangle.
The area of the square with side length a+b is (a+b)^2 = a^2 + 2ab + b^2. The area of one of the congruent right triangles is (1/2)ab, so the sum of the areas of the 4 triangles is 2ab. Therefore, the sum of the areas of the 4 triangles and the smaller square is:
a^2 + 2ab + b^2 + c^2
But this is also equal to the area of the larger square with side length a+b, which is (a+b)^2. So we have:
a^2 + 2ab + b^2 + c^2 = (a+b)^2
Expanding the right-hand side gives:
a^2 + 2ab + b^2 + c^2 = a^2 + 2ab + b^2
Canceling the common terms on both sides gives:
c^2 = a^2 + b^2
This is the Pythagorean theorem, which we have proved using the given diagram.

3. Soshi's rhombus has a base of 12 in. and a
height of 10 in. Jack's rhombus has base and
height measures that are double those of Soshis
rhombus. Compare the area of Jack's rhombus to
the area of Soshi's rhombus.
Answer:
The area of Jack's rhombus is four times the area of Soshi's rhombus.
Step-by-step explanation:
First, calculate the area of Soshi's rhombus. Use the formula for the area of a rhombus:
[tex]A = bh=\\A=(12)(10)=\\A=120[/tex]
Now, we have the Soshi's rhombus is 120 [tex]in^2[/tex].
Jack's rhombus' base and height are double those of Soshi's; multiply each value by two.
[tex]12*2=24\\\\10*2=20[/tex]
Now, substitute the values in the formula for the area of a rhombus:
[tex]A = bh=\\A=(24)(20)=\\A=480[/tex]
Notice that 480 is 4 times 120.
This is because area is a two-dimensional measure (measured in units squared, like [tex]in^2[/tex]) while length is a one-dimensional measure (measured in regular units, like cm and in), The one-dimensional measures of Jack's rhombus are double those of Soshi's, and to translate this to the two-dimensional measure of area, square 2 (2 squared is 2 times 2).
2 squared is 4, so:
the area of Jack's rhombus is four times that of Soshi's.

The statement that is true is:
"The results of the experiment might support the hypothesis or might not."
A scientist designs an experiment to test a hypothesis.
In such a scenario, it is important to note that the outcome of the experiment cannot be predicted with certainty.
The scientific method involves formulating a hypothesis, designing an experiment to test the hypothesis,
collecting and analyzing data and drawing conclusions.
The hypothesis is an educated guess that can be tested through experimentation.
It is important to remember that a hypothesis can never be proven to be 100% correct, only supported or refuted by the evidence obtained through experimentation.
It is not accurate to say that if the experimenter does the test correctly, the hypothesis will be proven correct.
This is because there are many variables that can affect the outcome of the experiment, and it is impossible to control all of them.
Additionally, a good experiment is not necessarily one that produces the most data.
A good experiment is one that is well-designed, carefully controlled, and yields reliable results.
The use of lab equipment is also not a requirement for conducting experiments.
While it is often necessary for certain types of experiments, many experiments can be conducted with simple materials and equipment.
Ultimately, the results of the experiment might support the hypothesis, or might not. If the results support the hypothesis, it can be considered a step towards validating the hypothesis.
The results do not support the hypothesis, it does not necessarily mean that the hypothesis is incorrect.
It could mean that the experiment was flawed, or that the hypothesis needs to be revised based on the new information obtained from the experiment.

How to calculate the actual amount of drink?We are told that each liter of pineapple juice yields the same amount of drink. This is referred to as the "r" ratio. Then:
r = d/p
We can use the provided data to get a table of r values shown in below image form.
The ratio for the first two data points is the same, but it is different for the third. This suggests the drink's recipe changed between the second and third batches.
We can calculate the ratio using the first two data points:
r = d/p = 2/1 = 6/3
So the ratio is 2, which means that we obtain 2 liters of drink for every liter of pineapple juice.
This ratio can be used to calculate the estimated amount of drink for the third batch:

Question 18
Mambo needs to save R2,322.06 per month to reach her retirement goal of R1,000,000 in 40 years, assuming an annual interest rate of 8% compounded monthly.
Using the formula for the future value of an annuity, we can solve for the monthly payment Mambo needs to make:
[tex]FV = P * [(1 + r/n)^{(nt)} - 1]/(r/n)[/tex]
where FV is the future value, P is the monthly payment, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.
Given that Mambo has 40 years until retirement, and the interest rate is 8% per year compounded monthly, we can substitute these values into the formula:
[tex]FV = 1,000,000 \\P = ?\\r = 0.08\\n = 12\\t = 40 \\1,000,000 = P * [(1 + 0.08/12)^(12*40) - 1]/(0.08/12)[/tex]

the surface area of a cylinder is 936pi squares meters. the radius is 13m use the formula sa=2b=ph. to find the height of cylinder.
Answer: The formula for the surface area of a cylinder is:
SA = 2πr^2 + 2πrh
where SA is the surface area, r is the radius, and h is the height.
In this case, we know that the surface area is 936π square meters and the radius is 13 meters. So we can plug those values into the formula and solve for h:
936π = 2π(13^2) + 2π(13)(h)
Simplifying:
936π = 338π + 26πh
936π - 338π = 26πh
598π = 26πh
h = 598/26 = 23
Therefore, the height of the cylinder is 23 meters.
Step-by-step explanation:
Step-by-step explanation:
you made some mistakes with the formula.
the surface area of a cylinder is
the outside mantle area
+
the 2 circle areas on top and bottom.
the outside mantle area is
2×pi×radius×height
the 2 circle areas are
2 × pi×radius²
in total that is
2×pi×radius×height + 2×pi×radius² =
2×pi×radius×(height + radius) = 936pi
2×pi×13×(height + 13) = 936pi
pi×(height + 13) = 36pi
height + 13 = 36
height = 36 - 13 = 23 m

There are 11 squares containing the black center square in the 5x5 grid.
To find the number of squares that contain the black center square, we'll consider the sizes of the squares and their positions in the 5x5 grid.
The black center square is a 1x1 square itself, so that's 1 square.
For 2 x 2 squares containing the center square, there are 4 possible positions (the center square can be in any corner). So, that's 4 squares.
For 3x3 squares containing the center square, there is only 1 possible position (the center square is exactly in the middle). So, that's 1 square.
4. For 4x4 squares containing the center square, there are 4 possible positions (the center square can be in any corner). So, that's 4 squares.
5. For 5x5 squares containing the center square, there is only 1 possible position (the center square is exactly in the middle).
So, that's 1 square.
Now, we'll add up the number of squares we found in each step:
1 + 4 + 1 + 4 + 1 = 11.

a battery company makes 12-volt car batteries. after many years of product testing, the company knows that the average life of its battery is normally distributed, with a mean of 44 months and a standard deviation of 7 months. a button hyperlink to the salt program that reads: use salt. (a) if the company guarantees a full refund on any battery that fails within the 36-month period after purchase, what percentage of its batteries will the company expect to replace? (round your answer to two decimal places.) % (b) if the company does not want to make refunds for more than 9% of its batteries under the full-refund guarantee policy, for how long should the company guarantee the batteries (to the nearest month)?
a) The percentage of batteries the company expects to replace is:
0.1271 * 100% = 12.71%
b) The company should guarantee the batteries for 34 months (rounded to the nearest month) to ensure that refunds are not made for more than 9% of its batteries under the full-refund guarantee policy.
Step by step explain about both part of the question?(a) Let X be the random variable representing the life of a battery. We want to find the probability that a battery fails within 36 months after purchase, which is equivalent to finding P(X ≤ 36).
Using the normal distribution formula with mean μ = 44 months and standard deviation σ = 7 months, we have:
Z = (X - μ) / σ = (36 - 44) / 7 = -1.14
Using a standard normal table or calculator, we find that the probability of a standard normal variable being less than or equal to -1.14 is 0.1271. Therefore, the percentage of batteries the company expects to replace is:
0.1271 * 100% = 12.71% (rounded to two decimal places)
(b) Let Y be the random variable representing the length of the guarantee period in months. We want to find the value of Y such that P(X ≤ Y) = 0.09, where X has the same normal distribution with mean μ = 44 months and standard deviation σ = 7 months.
Using the inverse normal distribution formula with mean μ = 44 months and standard deviation σ = 7 months, we have:
Z = invNorm(0.09) = -1.34
where invNorm is the inverse normal function. Solving for Y, we have:
(Y - μ) / σ = Z
(Y - 44) / 7 = -1.34
Y - 44 = -1.34 * 7
Y ≈ 34.42
Therefore, the company should guarantee the batteries for 34 months (rounded to the nearest month) to ensure that refunds are not made for more than 9% of its batteries under the full-refund guarantee policy.
