Red ribbons are wrapped around all the columns of a building. Each ribbon does not overlap itself. Each column has a radius of 3

Roman55 [17]

Hello!

If this long ribbon measures 144 $\pi$ feet, you can see, it was only multiplied by one number, which has the be the diameter of a column to get our circumference. If we divide this by our diameter 6 (diameter is double the radius, 3), we get our answer below.

144/6=24

Therefore, our answer is C) 24.

I hope this helps!

aleksandr82 [10.1K]

Answer:

The graph will show an initial value that is lower on the y-axis

Step-by-step explanation:

The exponential function has the next general form:

$y = ab^x$

where a is the initial amount and b is the base.

If the a value in the function is decreased, but remains greater than 0, the y-intercept of the curve decrease.

Mark and Tony share a sum of money in the ratio 3:5. What fraction of the money did Tony ratio receive?

gladu [14]

Answer:

Part A is 3/8 of the whole
Part B is 5/8 of the whole

Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 5 = 8

Part A = 3 and Part B = 5 are numerators for each fraction.

The fractions are then:
3/8 and 5/8

Meaning:
Part A is 3/8 of the whole
Part B is 5/8 of the whole

You didn't give the box plot, but to obtain the percentage of people between 20 and 37 years old, first of all, find the total number of people, T. Next, find the total number of people between 20 and 37 years old, t.

Then the percentage we want to find is:

P = T/t × 100
