Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
The area of a circle uses the radius of a circle, which is 1/2 the diameter.
In the calculation the radius is squared.
Since the diameter of the larger circle is twice as large the radius would be 2 times.
2 squared would be: 2^2 = 4
This means the area of the larger circle is 4 times larger which would make the ratio 4:1
Eli received the most votes
Step-by-step explanation:
Given percentages are:
Eli: 30%
Daphne: 27%
Celeste: 25%
Thaddeus: 18%
When a circle chart is used, the sum of all percentages is 100.
In case of finding the largest between the portions, the part with the greater percentage has the greater share in the chart.
According to given percentages, Eli has the highest percentage, which means that Eli received the most votes.
Hence,
Eli received the most votes

Answer:
706.5 inches squared
Step-by-step explanation:
The formula for the area of a circle is pi r^2. r being the radius. Because you have the radius, and pi is 3.14 in this case, your new formula is A=3.14(15)^2. 15 squared is 225, times 3.14 gives you 706.5
Your final answer is already in tenths so you don't need to round! Hope this helps :)) and brainliest is always appreciated
