Rozalie spent $26 at a parking garage in downtown Orlando. The garage charged a base free of $7.50 for the first hour and a hour

bagirrra123 [75]

ANSWER : Rozalie spent 6.73 hours at the garage

rate of change = $2.75
base fee = $7.50

set up your equation:
2.75h + 7.5 = 26
($2.75/hour plus the base fee of $7.50 equals the total amount spent, $26)

Now just solve for h

2.75h + 7.5 = 26
2.75h = 18.5
h = 6.727273 (rounded)
h = 6.73

So the answer would be Rozalie spent about 6.73 hours at the garage.

You spin the spinner shown below once. Each sector shown has an equal area.

a_sh-v [17]

Answer: P(not shaded sector) = 0.50

Step-by-step explanation:

Since we have given that

Number of shaded parts = 6

Number of unshaded parts = 6

Total parts = 6+6 = 12

So, Probability of getting not shaded sector is given by

$\dfrac{6}{12}\\\\=\dfrac{1}{2}\\\\=0.50$

Hence, P(not shaded sector) = 0.50
