Answer:
y = 2
Step-by-step explanation:
I keep doing the math for it and get 359 cubed inches (rounded to the closest whole number) when including the pi, and 114*pi cubed inches when I exclude it. The answer choices are 60*pi cubed inches, 65*pi cubed inches, 85*pi cubed inches, and 90*pi cubed inches. Can someone go through the math of this?
Large cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 9^2 x 15
= 1272.3 cubic inches
Smaller cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 3^2 x 5
= 47.1 cubic inches
1272.3 - 47.1 = 1225.2 cubic inches
1272/3.14 ≈ 390
The answer is 390 × pi.
Answer:
(x) = -5 (y) = 5
B. 2.50p ≥ 135; p ≥ 54
C. 2.50p ≥ 135; p ≥ 132.5
D. 135p ≥ 2.50; p ≥ 54
Answer:
2.50p ≥ 135 , p ≥ 54.
Thus, option (B) is correct.
Step-by-step explanation:
Given: The French club is sponsoring a bake sale and their goal is to raise at least $135.
We have to find the number pastries they must sell at $2.50 each in order to meet the given goal.
Let p be the number of pastries baker sales.
Then cost of p pastries at $2.50 each is 2.50p
and the goal is to raise at least $135 (135 or more than 135)
Thus, inequality becomes,
2.50p ≥ 135
Solving inequality,
Divide both side by 2.50, we have,
Simplify, we have,
p ≥ 54.
Thus, option (B) is correct.
Answer:
B
Step-by-step explanation:
Gradpoint
A. g > -30
B. g < -30
C. g > 34
D. g < 34
Answer:
Your answer should be D. g < 34
Step-by-step explanation:
Simply use the order of operations.
Remember, when dealing with a negative in an inequality, your sign will flip/change the opposite direction.
