Answer:
$360
Step-by-step explanation:
This is because 20% of $450 is $90. You subtract the $90 from $450 and you get your answer!
The answer to this question is x
Step-by-step explanation:
<u>25 minutes=3 miles</u>
<u>1 minute = 3/25 miles</u>
<u>20 minutes = 3/25 * 20 miles</u>
<u>= 2.4 miles</u>
<u>Therefore, the answer is 2.4 miles.</u>

Answer: x = 7</h3>
Work Shown:
Since the diameter AB cuts chord EF in half, we can prove AB is perpendicular to EF. So we have a right angle forming at ACF.
angle ACF = 90 degrees
angle ACF = 2(7x-4)
2(7x-4) = 90
14x-8 = 90
14x-8+8 = 90+8 .... add 8 to both sides
14x = 98
14x/14 = 98/14 ... divide both sides by 14
x = 7
-----
If x = 7, then
2(7x-4) = 2*(7*7-4) = 2*(49-4) = 2*45 = 90
this confirms the answer
