If its 13 inches total and each cookie is 1/2 inch thick you would do 13÷1/2 (an easier way to solve this is 13×2 because you get 2 cookies per every inch) this leaves you with 26 total cookies. 26 is your final answer.
Answer:
$20
Step-by-step explanation:
18 ten-dollar bills = 18×10
18×10=$180
He gave 16 of the bills = 16×10
16×10=$160
Now, the question is asking how much money he kept. This refers to the total amount of money, not just how many bills he kept.
(18×10) - (16×10)
180 - 160 = 20
Therefore, Jack kept $20 from selling the tickets.
Let L be the length and W be the width.
"the width of a rectangle is half as long as the length"
W = (1/2)·L
"the rectangle has an area of 18 square feet"
A = L·W = 18
Substitute,
L·W = 18
L·(1/2)·L = 18
(L²)/2 = 18
L² = 36
L = 6 feet
then W = (1/2) · L
W = (1/2) · 6
W = 3 feet
