Step-by-step explanation:
140/70=2 Therefore, 1 apple equals 2 percent
The remaining 30 percent times 2 equals 60
60 apples plus 140 apples equals 200 apples
Answer B
The answer is 769.3 cm²
The volume of the cylinder is : V = π r² h
<span>The ratio between the radius of the base and the height of the cylinder is 2:3:
r/h = 2/3
h = 3/2r
V = 1617 cm
</span>π = 3.14
1617 = πr² * 3/2 r
1617 = πr³ * 3/2
1617 * 2/3 = πr³
1078 = πr³
r³ = 1078/π = 1078/3.14 = 343
r = ∛343 = 7 cm
h = 3/2r = 3/2 * 7 = 10.5 cm
The surface area of the cylinder is:
SA = 2πr² + 2πrh
= 2 * 3.14 * 7² + 2 * 3.14 * 7 * 10.5
= 307.72 + 461.58
= 769.3 cm²
Answer:
-4
Step-by-step explanation:
that is the slope
<h3>
Answer: Choice B</h3><h3>2W+2( W+4 1/4) = 124 1/2</h3>
=========================================
Explanation:
L = length
W = width
"The length is 4 1/4 longer than the width" (paraphrase) so
L = W + 4 1/4
This means,
P = perimeter = 124 1/2
P = 2L+2W
2L+2W = P
2W+2L = P
2W+2( L ) = P
2W+2( W+4 1/4) = 124 1/2
We have the next number
The expanded form of the number is
Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain
Finally, the correct answer is
