Use the formula of the area of a trapezoid.
A=(B+b)·h/2
B=10ft
b=8 ft
A=95 ft
(10+8)·h/2=95|·2
18h=95·2
18h=190
h=190:18
h=10,5 ft
<em>Answer: 10,5 ft</em>

Answer:
$15.21
Step-by-step explanation:
17% of $13=0.17*13=2.21
13 (the price of the actual lunch) +2.21= 15.21
Alternatively, you can just do the operation:
13*(1+0.17)=15.21
This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip
Answer:
21x = 14
x = 1.5
Step-by-step explanation:
(-4)3y - 9x = -6
(3)4y - 12x = -8
-12y-9x=-6
12y-12x=-8
0 -21x = -14
-21x/- = -14/-
21x = 14
