Find the volume of an oblique circular cylinder that has a radius of five feet and a height
of three feet
Answer:
235.5 cubic feet
Step-by-step explanation:
The volume v of a circular cylinder whose base radius is r and height h is given as
v = πr^2h
where π is 22/7 or 3.14
Given that the radius is five feet and the height is three feet
the volume v = 3.14 *5^2 * 3
= 235.5 cubic feet
The volume of the oblique circular cylinder is 235.5 cubic feet

Bill needs to read 3 novels each month.
Let N be the number of novels Bill needs to read in M months.
Write an equation relating N to M. Then use this equation to find the number of novels Bill needs to read in 19 months.
Write the equation?
Number of the novels in 19 months: _ novels
Answer:
Each month Bill reads 3 novels so you get
N = 3m
If you plug in 6 for m we get
N = 3(6) = 18
Bill needs to read 18 novels in 19 months

Un muchacho le dijo a otro. "adivina cuántos años tengo si las dos terceras partes de ellos menos 1 es igual a mi edad actual menos 6".
Answer:
The age of the boy is 15 years
Step-by-step explanation:
Let us assume a be the age of the boy
So, two-third of his age is 2 ÷ 3 × a
As the boy said that two-third minus 1 so it would be equivalent to
2 ÷ 3 × to - 1
ANd, his current age is a and now if we deduct 6 so
a - 6
AFter this, two-third minus 1 is equivalent to a minus 6
So,
2 ÷ 3 × a - 1 = a - 6
- 1 + 6 = a - 2 ÷ 3 × a
5 = 1 ÷ 3 × a
a = 3 × 5
= 15
Hence, The age of the boy is 15 years

Answer:
I think the answer would be A or B, the best would be B.
Step-by-step explanation:
K so since it is monthly, it would not be all positive data. So you are left with A or B. Integers are numbers that are positive and negative so since the data can be a range of positive and negative numbers, that is why the data set of all integers (b) is the best choice.

If f(x) = 3x + 2, what is f(5)?
Hi there!
[tex]\large\boxed{f(5) = 17}}[/tex]
f(x) = 3x + 2, find f(5):
To find f(5), we simply substitute in 5 for x:
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
