Answer:
Mrs. Stewart paid $86.25 for all the books.
Step-by-step explanation:
With the information provided, you have to add the result of multiplying the nine books for its price plus the remaining books for the price per book. To find the number of the remaining books you can substract the nine books from the total amount Mrs. Stewart purchased.
Cost=(9*4.95)+((15-9)*6.95)
Cost=44.55+41.7
Cost=86.25
According to this, the answer is that Mrs. Stewart paid $86.25 for all the books.
Answer:
$7,250
Step-by-step explanation:
14000 + 500 = 14500 - reverse the subtraction
14500/2 = 7250 - do the opposite of multiplication
Lets check 7250*2 = 14500 - 500 = 14,000
Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
