Answer:
8 : 343
Step-by-step explanation:
Given 2 similar figures
ratio of sides = a : b, then
ratio of volumes = a³ : b³
Here the ratio of edges = 2 : 7, hence
ratio of volumes = 2³ : 7³ = 8 : 343
Answer:
Step-by-step explanation:
Adding 2a to both sides
Taking sqrt on both sides
(-2,-4) is the correct answer.
Hope this helps:)
<h3>
Answer: 12 square units</h3>
Explanation:
Rectangle ABDE is 4 units across the horizontal, and 2 units tall.
The area of this rectangle is length*width = 4*2 = 8 square units.
Triangle BCD has a base of 4 and height 2. The area of which is base*height/2 = 4*2/2 = 4 square units.
The total area is
rectangle + triangle = 8 + 4 = 12 square units
Answer:
40 14/25 years
Step-by-step explanation:
Well, this certainly is fun.
First, to find the fraction of the doctor's life which 13 years represents, subtract the fractions from 1 (and in this case l stands for lifetime):
So, multiply this equation by the reciprocal of 25/78 to isolate one of l:
years
