Answer: 7 multiple choice questions and 8 free response questions
Step-by-step explanation: m is the number of multiple choice questions and f is the number of free response questions.
m+f=15
m+2f=23
You can subtract the first equation from the second, and get f=8
m+8=15
m=7
Perimiter=2(L+W)
P=2(100+120)
P=2(220)
P=440
0.1 per foot
440*0.10=44

Answer:
(b) 80/3π in³
Step-by-step explanation:
The volume of a circular cone is given by ...
V = 1/3πr²h . . where r is the radius (half the diameter) and h is the height
Your cone has r = 4 inches and h = 5 inches, so its volume is ...
V = (1/3)π(4 in)²(5 in) = 80/3π in³
The volume of the cone is exactly (80/3)π cubic inches.
