It is given that the cost of renting a car is a flat rate of $45 per day plus $0.25 for each mile you drive. So cost as a function of distance traveled
is
.
When
,
![75=45+0.25x\\ 0.25x=30\\ x=120](https://tex.z-dn.net/?f=%2075%3D45%2B0.25x%5C%5C%200.25x%3D30%5C%5C%20x%3D120%20)
So for $75, the driver can drive ![120 \;miles](https://tex.z-dn.net/?f=%20120%20%5C%3Bmiles%20)
Answer:
If the bisectors of two adjacent angles are perpendicular to each other, are the angles then supplementary angles?
Suppose two angles ABC and CBD are x and y.
x+y = 180 deg.
The bisector of angle ABC (BE) and the bisector of angle CBD (CF) will form angle EBF = (x/2)+(y/2) = 180/2 = 90 deg.
Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle
Adjacent angles are when the 2 angles have a common vertex and a common arm.
if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.
Then the sum of the 2 adjacent angles is a right angle - 90°.
When 2 angles add up to 90°, they are called a pair of complementary angles.

Answer:
Step-by-step explanation:
S - 4πc^2 = 6πct
t = (S - 4πc^2)/6πc
t = S/(6πc) - 2/3 c
assuming c ≠ 0
