When the sum of the internal angles of a polygon is 10 right angles, then how many sides does it have?

Varvara68 [4.7K]

Answer:

Step-by-step explanation:

Let's say our sum is s.

s = 10 right angles

a right angle is 90 degrees

s = 10 (90)

s= 900

Given the amount of sides in a polygon (n), the sum of the interior angles is equal to

(n-2) * 180

Therefore, the sum of the interior angles is equal to

(n-2) * 180 = 900

divide both sides by 180 to help isolate n

n-2 = 5

add 2 to both sides to isolate n

n = 7

Elyse uses 42 gallons of water in a 10-minute shower. Write and solve a prediction problem that uses this information

kvv77 [185]

Let

x-----> the time in minutes

y------> the number of gallons of water

we know that

the unit rates is equal to

$\frac{y}{x} = \frac{42}{10}=4.2\frac{gal}{min}$

the unit rate is equal to the slope of the linear equation

then

$y=4.2x$

Problem

1) How many gallons of water will Elyse use in three minutes in the shower?

For x=3 minutes

substitute in the equation above

$y=4.2x$

$y=4.2*3$

$y=12.6 gal$

the answer is

12.6 gal
