Answer:

62.84

Step-by-step explanation:

Volume of both cones is approximately 12.57

formula= pi*r^2*h/3

Volume of the cylinder is approximately 37.7

formula= pi*r^2*h

you add the volumes

12.57+12.57+37.7

= 62.84

Alexeev081 [22]
Assume the following:

Brad has been in the soccer team for b years.

Scot has been in the soccer team for s years.


"The number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has"

means: b=5s-2


"in total,the boys have been on the soccer team for 10 years."

means: b+s=10


so we have the equations:

i) 
b=5s-2

ii) 
b+s=10


substitute b in ii) with 5s-2, as they are equal, from i

(5s-2)+s=10

5s-2+s=10

6s=12

s=2, 


then , from b+s=10, b=8


Answer: Brad has been in the team for 8 years.

Alexeev081 [22]

Answer:

911,690.

Step-by-step explanation:

Please consider the complete question.

A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.

We will use exponential growth formula to solve our given problem.

y=a\cdot (1+r)^x, where,

y = Final value,

a = Initial value,

r = Growth rate in decimal form,

6.75\%=\frac{6.75}{100}=0.0675

y=390,000\cdot (1+0.0675)^x

y=390,000\cdot (1.0675)^x

To find the population after 13 years, we will substitute x=13 in population growth equation as:

y=390,000\cdot (1.0675)^{13}

y=390,000\cdot 2.3376661492982871

y=911689.798226331969

Upon rounding to nearest whole number, we will get:

y\approx 911,690

Therefore, the population of the city after 13 years would be 911,690.
