Answer:
The volume of the cylinder is 3,080 cm^3
Step-by-step explanation:
Mathematically, we have the volume calculated as;
V = pi * r^2 * h
r = radius = 14 cm/ 2 = 7 cm (14 cm is the diameter and the radius is half the diameter)
h = height = 20 cm
Substituting these values;
V = 22/7 * 7^2 * 20
V = 22 * 7 * 20
V = 3,080 cm^3

A person wants to purchase a pair of shoes and some pairs of socks. He has less than $121 to
spend. If a pair of shoes costs $30 and each pair of socks costs $8, what is the maximum
number of pairs of socks he can purchase?
Answers
the answer is 11
first you need to subtract 30 from 121 since you want one pair of shoes
then to know how many socks you can have divide 91 (the result) and 8 (the price of the socks)
and you can only buy 11

Whats the slope of the line?
Answers
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.

A city's population increases by 5% every year. If its population today is 300,000, write a function that models the population after x years.
Answers
Answer:
f(x) = 300,000(1.05)^x
Step-by-step explanation:
Use the exponential growth equation:
f(x) = a(1 + r)^x
Plug in 300,000 as a, since it is the original population:
f(x) = 300,000(1 + r)^x
The city's population is growing at 5% each year, so plug in 0.05 as r:
f(x) = 300,000(1 + 0.05)^x
f(x) = 300,000(1.05)^x
So, the function for the population growth is f(x) = 300,000(1.05)^x
Find the median of the following numbers:
95, 113, 95, 105, 86, 122
Answers
Answer:
100
Step-by-step explanation:
First, order the numbers from least to greatest.
86, 95, 95, 105, 113, 122
Second, look for the middles numbers, if you have an even amount of numbers you will have to find the mean of the two middle numbers.
86, 95, 95, 105, 113, 122
Thirdly, add 95 and 105 together and then divide by two because two is the total amount of numbers you have.
(95 + 105) / 2 = 100.
So the median is 100

If 35 people going to the movie bought popcorn and that was 20% of all the people at the movie how many people were at the movie
Answers
Answer:
Im pretty sure it would be 700 but im most likely wrong.
If 35 people is 20% of all people, we can assume that 35 is 1/5 of all the people at the movie since 20% is 1/5 of 100%
All we have to do is multiple 35 by five.
I can prove my answer by dividing 175 by 5 which would give me 20% of 175
