I know only how to solve one, using the Pythagorean theorem, you have to square 45
Which is
45^2 - 25^2 = 1400
Now you multiply 37.42 x 37.42 which gets you 1400.2564

I’m in 8th grade by the way

What is the area of the pool and the area of the pool and the walkway? Show your work.

andrew11 [14]

Answer:

Part a) The area of the pool is $320\ m^{2}$

Part b) The area of the pool and the walkway is $520\ m^{2}$

Step-by-step explanation:

we know that

The area of the rectangle is equal to

$A=LW$

where

L is the length side

W is the width side

Part a) What is the area of the pool?

we have

$L=20\ m$

$W=16\ m$

substitute the values

$A=(20)(16)=320\ m^{2}$

Part b) What is the area of the pool and the walkway?

we have

$L=26\ m$

$W=22\ m$

substitute the values

$A=(26)(22)=520\ m^{2}$

Sven is trying to find the maximum amount of time he can spend practicing the five scales of piano music he is supposed to be wo

Katena32 [7]

Answer:

He should spend 3 minutes or less on each scale

Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal

Step-by-step explanation:

Let

t ------> is the number of minutes he spends on each scale

Remember that the phrase "at least" is equal to "greater than or equal"

The inequality that represent this scenario is

$70-5t \geq 55$

solve for t

$-5t \geq 55-70$

$-5t \geq -15$

Multiply by -1 both sides

$5t \leq 15$

Divide by 5 both sides

$t \leq 3$

Sven is incorrect

He should spend 3 minutes or less on each scale

Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal
