The ratio of women to men working at a grocery store is 4 to 5. There are 16 women working at the store . What is the total numb

Minchanka [31]

Answer:

36 people

Step-by-step explanation:

The ratio of women to men working at a grocery store is 4 to 5.

The ratio =

Women : Men

4 : 5

The sum of the proportion is 4 + 5 = 9

There are 16 women working at the store .

Let us represent the total number of people working at a grocery store as x

Hence:

4/9 of x = 16 women

4/9 × x = 16

4x/9 = 16

Cross Multiply

4x = 16 × 9

x = 16 × 9/4

x = 36 people

The total number of people working in the grocery store is 36 people

Select the correct answer. A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertice

erma4kov [3.2K]

Answer:

* The scale factor of the dilation is 2.5

Step-by-step explanation:

* Lets talk about dilation

- A dilation is a transformation that changes the size of a figure.

- It can become larger or smaller, but the shape of the

figure does not change.

- The scale factor, measures how much larger or smaller

the image will be

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

* In the problem

- The vertices of the triangle is A (0 , 0) , B (0 , 4) , C (6 , 0)

and its image A' is (0 , 0) , (0 , 10) , (15 , 0)

∵ 10 ÷ 4 = 2.5

∵ 15 ÷ 6 = 2.5

∴ The scale factor is 2.5

∵ 2.5 > 1

∴ The image of the triangle will be larger

* The scale factor is 2.5
