Answer: C

Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

The utilization of two or more additional numbers that compares is known as the ratio.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.

Let 'x' be the weight of Anne's cat. Then the equation is given as,

5 / 7 = 20 / x

Simplify the equation, then we have

5 / 7 = 20 / x

1 / 7 = 4 / x

x = 28 kg

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

Step-by-step explanation:

Step-by-step explanation:

1. Formula for simple interest,

[tex]a = p(1 + rt)[/tex]

where

a = Final amount

p = Principal amount

r = annual interest rate

t = time in years

given p = 1250

r = 4.25/100 (r is a raw number, not percentage, so we need to divide 100 here to get the raw number)

t=4

Substitute values into formula to get a.

[tex]a = 1250(1 + (\frac{4.25}{100})(4)) \\ = 1250(1 + 0.17) \\ = 1250(1.17) \\ = 1462.50dollars[/tex]

Let's use the simple interest to calculate Henry's final amount first.

p = 5000

r = 4.2/100

t = 4

[tex]a = 5000(1 + ( \frac{4.2}{100} )(4)) \\ = 5000(1 + 0.168) \\ = 5000(1 .168) \\ = 5840 \: dollars[/tex]

To calculate the interest paid, just use the final amount minus the principal amount

[tex]a - p = 5840 - 5000 \\ = 840dollars[/tex]

Now we will do the exact same method for Ingrid.

p = 5,000

r = 3.9/100

t = 6

[tex]a = 5000(1 + ( \frac{3.9}{100} )(6)) \\ = 5000(1 + 0.234) \\ = 5000(1.234) \\ = 6170 \: dollars[/tex]

[tex]a - p = 6170 - 5000 \\ = 1170dollars[/tex]

Difference in interest between 2 of them =

Interest of Ingrid Loan - Interest of Henry Loan

= 1170 - 840

= $330

Answer:

15/21

Step-by-step Explanation:

Because 1/3 and 2/7 do not have the same denominator, we will have to multiply them to get one that they'll both share.

In this case, you multiply both denominators, 3 and 7, to get 21.

We do the same with the numerators, but in a different way.

We're gonna multiply the numerators by the OTHER fractions' denominators this time. So, we do this:

1 x 7 = 7

2 x 3 = 6

We end up getting these fractions:

7/21

6/21

And now, we just subtract 6 from 21, to get 15.

And you get 15/21.

I hope I helped you, and a "Brainliest" is always appreciated! ☺

Answer:

The value of a₂₇ is 788

Step-by-step explanation:

a₁₉ = 548

a₃₃ = 968

Now,

a₁₉ = 548 can be written as

a + 18d = 548 ...(1) and

a₃₃ = 968 can be written as

a + 32d = 968 ...(2)

Now, from equation (2) we get,

a + 32d = 968

a + 18d + 14d = 968

548 + 14d = 968 (.°. a + 18d = 548)

14d = 968 - 548

14d = 420

d = 420 ÷ 14

d = 30

Now, for the value of a put the value of d = 30 in equation (1)

a + 18d = 548

a + 18(30) = 548

a + 540 = 548

a = 548 - 540

a = 8

Now, For a₂₇

a₂₇ = a + 26d

a₂₇ = 8 + 26(30)

a₂₇ = 8 + 780

a₂₇ = 788

Thus, The value of a₂₇ is 788

Slope= 2 ; y intercept= 4

Step-by-step explanation:

Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points

Slope = (4-0)/(0-(-2) = 4/2 = 2

y intercept is where the line intercepts the y axis: it happens in (0;4)

Answer:

Answer:

Suppose we have a system of two linear equations, this can be written as:

y = a*x + b

y = c*x + d

Now, we have 3 possible cases here.

The solutions of the system are the points where the graphs of the linear equations do intersect.

Then, if for example, we have two parallel lines (two parallel lines never intersect) we have no solutions.

And we know that two lines are parallel if they have the same slope and different y-intercept.

Then the system:

y = a*x + b

y = a*x + c

has no solutions.

If we have both equal lines, then the lines intersect in infinitely many points, meaning that we have infinite solutions, then the system:

y = a*x + b

y = a*x +b

has infinite solutions.

And if the lines intersect only one time we have one solution, and this happens when the slopes are different, so the system:

y = a*x + b

y = c*x + d

has only one solution.

Now, if we have more equations:

y = a*x + b

y = c*x + d

y = k*x + n

We have more equations than variables, then this system only has one solution of the 3 lines intersect at the same point, which is really rare.

One case where we have a solution here is if the 3 equations have the same y-intercept:

y = a*x + b

y = c*x + b

y = d*x + b

where the solution is the point (0, b)

Of course, there are other possible solutions, but these are not as formulaic as this ones.

Answer:

475 children

Step-by-step explanation:

A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer

Step 1

We find the total number of visitors the restaurant had over the weekend. This is calculated as:

Let the total number of visitors = x

4/9 × Total number of visitors = 380 Adults

4/9 × x = 380

4x/9 = 380

Cross Multiply

4x = 9 × 380

x = 9 × 380/4

x = 855 visitors.

Step 2

The number of visitors that were children is calculated as:

Total number of visitors - Number of Adults

= 855 visitors - 380 Adults

= 475 children

==========================================================

Explanation:

When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.

In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.

In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.

If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange.

The ratio of all Jerseys to Jerseys that are Orange =

512 : 64

8 : 1

Step 2

If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same?

Since we are maintaining the ratio in step 1

Let the number of orange jerseys = x

600 : x = 8 : 1

Hence

600/x = 8/1

Cross Multiply

8 × x = 600 × 1

8x = 600

x = 600/8

x = 75

Therefore, this year, the number of orange jerseys = 75

Answer:

The area of this figure is 22 meters squared

Step-by-step explanation:

Two shapes exist on this figure: a rectangle and a triangle. We must first find the area of the rectangle and add that area to the area of the triangle. So first, let's solve the rectangle.

As the area of a rectangle is length multiplied by width, we have 8 * 1 = area, or 8 meters squared. Now we save the value of 8 to add to the area of the triangle. So let's now figure out the area of the triangle.

As the area of a triangle is A = (HB)/(2), or that triangles height multiplied by its base, and dividing that whole number by 2, we can substitute numbers into this equation. This means we take 3.5, the height of the triangle, and multiply that number by 8, the base of the triangle, to get a value of 28. We then divide 28 by 2 to satisfy the equation A = (HB)/(2), and we get the value of 14.

Because of this, we add 8, the area of the rectangle, and 14, the value of the triangle to get a total value of 22. Now let's not forget to add meters squared as the unit of measurement as stated in the question.

This means that the total area of this figure is 22 meters squared.

V = 1/3 * pi r^2 h

V = 1/3 * pi * 5/2^2 * 6

V = 1/3 * pi * 25/4 *6
