VikaD [51]4 years ago
7 0

Answer:

<h2>k = 20</h2>

Step-by-step explanation:

<h3>\frac{20}{8}  =  \frac{4k}{32}</h3>

To find k first of all cross multiply

We have

32k = 640

Divide both sides by 32

That's

<h3>\frac{32k}{32}  =  \frac{640}{32}</h3>

We have the final answer as

<h3>k = 20</h3>

Hope this helps you

Bonnie planted a garden in her backyard. Both the garden and the backyard are right triangles. The garden is proportional to the
Mandarinka [93]
You can find the area of Bonnue's backyard by comparing the hypotenuse of the garden to the hypotenuse of the back yard.  If the hypotenuse of the garden is 10 (with the side lengths being 6, 8 and 10 - the longest is always the hypotenuse) and the hypotenuse of the back yard is 30, this is a scale factor of 3 (3 times longer).

This means the other two sides would also be 3 times longer.

6 yards x 3 = 18
8 yards x 3 = 24

To find the area using these dimensions, you will use the formula for finding the area of a triangle.

A = 1/2bh
A = 1/2 x 18 x 24
A = 216 square yards

The area of the backyard is 216 square yards.

Suppose you are a salesperson for
Sliva [168]

Answer:

27,000$ worth of sales

Step-by-step explanation:

What you need to earn - what you earn monthly = 1/6 of the amount you need to sell.

4000 - 2200 = 1800

1800 is ONE fifteenth of the sales.

1800 * 15 = 27,000.

You must sell MORE than $27,000 worth of sales in order to earn more than $4000.
