Answer:
Dori has $48 left.
Step-by-step explanation:
The boat costs twice as much as the goggles, divide 8 by 2 to find the price of the goggles. The price of the goggles is $4.
Add $8 and $4 to get $12. This is the total money Dori spent.
Since this is 1/5 of her money, multiply $12 by 5 to get $60. This is the money Dori had.
Subtract the $12 from the $60 to get $48. This is the money Dori has left.
Answer:
6.1
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) * h where b1 and b2 are the lengths of the bases
108.6 = 1/2 ( 12+p) *12
108.6 = 6 (12+p)
Divide each side by 6
108.6 /6 = 12+p
18.1 = 12+p
Subtract 12 from each side
18.1-12 = 12+p-12
6.1 = p
