Well first you would set up your ratio, 17/x = 35/100. You are trying to find x. To do so you cross multiply and divide. So first you have 17× 100 which equals 1700. The you divide that number by 35 which is around 48 like you said. I usually just round to the hundredths place so just cut it at 48.57 but to be safe say approximately 48.57

Last year, there were 148 pies baked for the bake sale. This year, there were c pies baked. Using c, write an expression for the

solniwko [45]

$\huge{\boxed{c+148}}$

We need to find the number of pies baked in years 1 and 2.

There were 148 pies baked in year 1. $148$

There were $c$ pies baked in year 2. $148+c$

Rearrange the terms so the variable is first. $c+148$

9. If it takes Joel 30 seconds to install each

DaniilM [7]

Answer:

20

Step-by-step explanation:

Since we have given that

Dimensions of a triangle he has to use for fencing are

15 feet, 8 feet, and 20 feet.

1) For making it a right triangle it must satisfy the "Pythagoras theorem" which states that

$H^{2} = B^{2} + P^{2}$

$20^{2} = 15 + 8^{2}$

$400 \neq 225 + 64$

$400 \neq 289$

No, it will not be able to make a right triangle.

2) Joel cut the longest piece of wood in order to make a right triangle.

So, from above we get that

$\sqrt{} 289 = 17 feet$

So, the longest side must be 17 feet.

It takes him 30 seconds to install each foot of fencing,

The total perimeter of fencing will be

17 + 15 + 8 = 40 feet

So, for 1 foot he needs = 30 seconds

For 40 feet, he will need

40 × 30 = 1,200 seconds

1200/600 = 20 minutes

Hence, he needs 20 minutes to install all of the fences.
