Answers
Answer:
360°
Step-by-step explanation:
xjjdjdjdjedjejdjej
hypotenuse side = 12
height = √12^2 - 6^2
= √144 - 36
= √108
= 10.39
area of one triangle = 1 / 2 bh
b = base
h = height
area of one triangle = 1 / 2 × 6 × 10.39
area of one triangle = 31.17 unit^2
area of 2 triangle = 2(31.17) = 62.34 unit^2
area of non shaded sector.
area of the sector = 120 / 360 × 3.14 × 6^2
area of the sector = 37.68 units^2
area of the shaded portion = 62.34 - 37.68
= 24.66 unit^2

Step-by-step explanation:
(-4x+4)(x^3+4x^2)
a b c d
using foil method multiply
term a by term c and d
-4x * x^3= -4x^4
-4x * 4x^2= -16x^3
*dont forget to add the exponents, when x is by itself you it always has an imaginary 1
then multiply term b by term c and d
4 * x^3= 4x^3
4 * 4x^2= 16x^2
line up all of your answers from biggest exponent to smallest
-4x^4-16x^3+4x^3+16x^2
we can combine like terms with -16x^3 and 4x^3 becaus ethey have the same exponent value

Esther estimates that she will need about $8,600 for the first year of tuition at college. Her grandparents contribution will cover 65% of the tuition expenses, and Esther will need to save to pay for the rest. If Esther has 2 years to save, what is the minimum amount that she should save each month?
Answers
Answer:
$125.42
Step-by-step explanation:
Her grandparents will cover 65% of $8600, which is 8600 * 0.65 = $5590. Therefore, she needs to pay for the part they're not covering, which is $8600 - $5590 = $3010.
2 years = 24 months, so assuming she wants to save the same amount each month, we need to divide $3010 by 24 to get the amount per month. This gets us $125.42
The minimum amount that she should save each month for two years is $125.42.
What is the minimum amount she would have to save each month?Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.
Amount given by her grandparents = 65% x 8600= $5590
Amount she would have to save each month for two years = (8600 - $5590) / 24 = $125.42

The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)
cm. What is the measure of the sides?
Answers
Answer:
The measure of the sides is 20 cm.
Step-by-step explanation:
Opposite side of a parallelogram:
Opposite sides of a parallelogram are congruent, that is, they have the same measure.
Measures (2x+10) cm and (x+15) cm:
This means that:
[tex]2x + 10 = x + 15[/tex]
[tex]2x - x = 15 - 10[/tex]
[tex]x = 5[/tex]
2x + 10 = 2*5 + 10 = 10 + 10 = 20
The measure of the sides is 20 cm.

A store owner has 12 pounds of pasta worth 70¢ a pound. She wants to mix it with
pasta worth 45¢ a pound so that the total mixture can be sold for 55¢ a pound
(without any gain or loss). How much of the 45¢ pasta must she use?
Answers
Answer:
The store owner must use 18 pounds of the 45 ¢ pasta.
Step-by-step explanation:
Given that a store owner has 12 pounds of pasta worth 70 ¢ a pound, and she wants to mix it with pasta worth 45 ¢ a pound so that the total mixture can be sold for 55 ¢ a pound, to determine how much of the 45 ¢ pasta must she use, the following calculation must be performed:
100 x 0.7 + 0 x 0.45 = 70
90 x 0.7 + 10 x 0.45 = 67.5
50 x 0.7 + 50 x 0.45 = 57.5
40 x 0.7 + 60 x 0.45 = 55
40 = 12
60 = X
60 x 12/40 = X
720/40 = X
18 = X
Thus, the store owner must use 18 pounds of the 45 ¢ pasta.

The life in hours of a biomedical device under development in the laboratory is known to be approximately normally distributed. A random sample of 15 devices is selected and found to have an average life of 5625.1 hours and a sample standard deviation of 226.1 hours.
Required:
a. Construct and interpret a 95% (two sided) confidence interval for the population standard deviation of the life of a biomedical device.
b. Test the hypothesis that the true mean life of a biomedical device is greater than 5500 using the P-value approach.
Answers
Answer:
Part a [5522.3511 ; 5727.8488]
Part b. The p-value is 0.050115.
The H0 is rejected and concluded that the true mean life of a biomedical device is greater than 5500.
Step-by-step explanation:
The 95 % confidence interval for the mean of the population is given by
∝= 1- 0.95= 0.05
υ= n-1= 15-1= 14
x`± t ∝() s / √n
5625.1 ± { t (0.05) (14)} 226.1 / √15
5625.1 ± 1.76 * 226.1/3.8729
5625.1 ± 102.7488
[5522.3511 ; 5727.8488]
Part b
State the null and the alternate hypothesis
H0: u= 5500 against the claim Ha: u > 5500
the test statistic
t= x`- u/ s/ √n
t= 5625.1-5500/226.1 / √15
t=2.143
The p-value is 0.050115.
The result is not significant at p < 0.05.
The H0 is rejected and concluded that the true mean life of a biomedical device is greater than 5500.
You spin a spinner that is equally divided into 5 parts, and then you spin it again. 1 part is pink, 2 parts are blue, and 2 parts are black. What is the probability of the spinner dropping on a blue section on the first spin and then a blue section of the second spin?
Answers
Answer:
There is a 16% chance of the spinner dropping on a blue section on the first spin and then a blue section of the second spin.
Step-by-step explanation:
Given that I spin a spinner that is equally divided into 5 parts, and then I spin it again, knowing that 1 part is pink, 2 parts are blue, and 2 parts are black, to determine what is the probability of the spinner dropping on a blue section on the first spin and then a blue section of the second spin the following calculation must be performed:
Blue parts: 2
Total Parts: 5
2/5 = 0.4 = 40%
0.40 x 0.40 = 0.16
Thus, there is a 16% chance of the spinner dropping on a blue section on the first spin and then a blue section of the second spin.

Answers
Answer:
The animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats
[tex]Cost = 51.275[/tex]
Step-by-step explanation:
The given parameters can be summarized as:
[tex]\begin{array}{cccc}{} & {x} & {y} & {Total} & {Protein} & {70} & {21} & {168} &{Fats}& {9} & {7} & {27} & {Minerals} & {7} & {1} & {14}& {Cost} & {21} & {7} & {} \ \end{array}[/tex]
Where: x = Soybeans and y = Oats.
So, the system of equations are:
[tex]70x + 21y = 168[/tex]
[tex]9x +7y = 27[/tex]
[tex]7x + y = 14[/tex]
[tex]Cost = 21x + 7y[/tex]
The best way to solve this, is using graph
Plot the following equations on a graph, and get the points of intersection:
[tex]70x + 21y = 168[/tex]
[tex]9x +7y = 27[/tex]
[tex]7x + y = 14[/tex]
From the attached graph, we have:
[tex](x_1,y_1) = (1.636,2.545)[/tex]
[tex](x_2,y_2) = (1.775,1.575)[/tex]
[tex](x_3,y_3) = (2.023,1.256)[/tex]
Substitute each of the values of x's and y's in the cost function to get the minimum cost:
[tex]Cost = 21x + 7y[/tex]
[tex](x_1,y_1) = (1.636,2.545)[/tex]
[tex]Cost = 21 * 1.636 + 7 * 2.545[/tex]
[tex]Cost = 52.171[/tex]
[tex](x_2,y_2) = (1.775,1.575)[/tex]
[tex]Cost = 21 * 1.775 + 7 * 1.575[/tex]
[tex]Cost = 48.3[/tex]
[tex](x_3,y_3) = (2.023,1.256)[/tex]
[tex]Cost = 21 * 2.023 + 7 * 1.256[/tex]
[tex]Cost = 51.275[/tex]
The values of x and y that gives the minimum cost is:
[tex](x_2,y_2) = (1.775,1.575)[/tex]
and the minimum cost is:
[tex]Cost = 48.3[/tex]
Hence, the animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

On the left side of the chart, is the x values. The x values are listed on the x axis which is the horizontal line.
The right side of the chart are the y values. The y values are listed on the y axis which is the vertical line.
Knowing this, we can start
First, for all the answer that we know the x value, we need to find the number that matches on the x axis. Once we find that number, we go up or down on the y axis until we find the line.
If we know the y value, we need to find the number that matches on the y axis. Then we will go right until we find the line.
Remember - There CAN NOT be two y values for the same x value but THERE CAN BE two x values for the same y value

- The sum of three numbers is 918. One of the numbers, x, is twice as much as the sum of the
other two numbers. What is the value of x?
Answers
Answer:
x = 612
Step-by-step explanation:
x = 2(y + z) Divide by 2 to isolate y + z
x/2 = y + z Set up the sum of three numbers
x + y + z = 918 Substitute x / 2 for y + z
x + x/2 = 918 Combine like terms
3/2 x = 918 Multiply both sides by 2/3
2/3 * 3x/2 = 2/3 * 918
x = 612
