Tia went home and said to her mom,"I learned that 10 to the power of 4 is the same as 40,000."
Tia made a mistake in her thinking. Exponent represents the number of zeros.
means we multiply 10 four times

For exponent 4, we put 4 zeros. So answer is 10,000.

Answer: 239 m^2
Step-by-step explanation:
Find the area for parts of the shape first.
12 x 5 = 60 x 2 (2 same looking parts) = 120
17 x 7 = 119
Add together values:
120 + 119 = 239 m^2
First, find the expected number of scooters rented per month:
As the data is symmetrical, E(X) (the expected value) is the middle value. So, on average, 2.5 scooters should be taken per month.
His total costs were 5 * 3000 = $15,000
So, to break even, he needs to make $15,000.
He will be selling for 5 years, or 60 months.
As a result, he needs to make 15000/60 = $250/month
As he is selling 2.5 scooters on average, he needs to rent each for:
$250/2.5 = <u>$100/month</u>
Next would be to subtract 4 from both sides:
2x + 4 (- 4) = 16 (- 4)
2x = 12
