Hello!

You use the Pythagorean Theorem to solve this

$a^{2} + b^{2} = c^{2}$

Put in the values it tells you

$a^{2} + 1^{2} = \frac{5}{4} ^{2}$

Square the numbers

$a^{2} + 1 = \frac{25}{16}$

Subtract 1 from both sides

$a^{2} = \frac{9}{16}$

Take the square root of both sides

$a = \frac{3}{4}$

The answer 3/4 or 0.75

Hope this helps!

Jamal bought 2 pounds of red apples and 3.2 pounds of green apples from a grocery store, where both kinds of apples are $1.65 a

In this question, we're trying to find out how much Jamal spent on apples.

We know that he bought 2 pounds of red apples and 3.2 pounds of green apples.

We also know that each pound of apples, no matter what kind it is, are $1.65 a pound.

In order to find the total cost of these apples, we would need to multiply the amount of pounds he has to the cost per pound.

Solve:

2 · 1.65 = 3.3‬0

3.2 · 1.65 = 5.28‬

Add those numbers together:

5.28‬ + 3.30 = 8.58‬
