Ramona purchases three baseball cards online for $72.50. There is a 2% processing fee. What is the total cost of the baseball cards? Round to the nearest cent.

Answers

Answer:

$73.95

Step-by-step explanation:

2% of 72.50 is 1.45

72.50 + 1.45 = 73.95

The answer would be 73.95. If you multiply 0.02x72.50, you will get 1.45. So if you add 72.5+1.45, you will get 73.95.

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
please help me i will give brainliest to first person to anwser.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Maria needs 3/4 foot of string to make each bracelet. How many feet of string does she need to make 9 bracelets?

Answers

Answer:

6.75 foot

Step-by-step explanation:

3/4 foot of string is needed for one bracelet so we multiply that with 9:

3/4*9

=27/4

=6.75 foot

If each bracelet needs 3/4 of string therefore in order to make it easier turn the fraction into decimal by dividing the numerator and the denominator which is 0.75 then multiply by the amount of bracelets which is 9 which gets you to 6.75 in a fraction it’s
6 3/4.

Answers

Answer:

3.62 inches

Step-by-step explanation:

Given :

Ed's string length = 21.72 inches

Georgiana's string length = 1/6 of Ed's string length

To Find :

Georgiana's string length

Solving :

Georgiana's string length = 1/6 of Ed's string length

Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Georgiana's string length = 3.62 inches

Answer:

3.62 inches

Step-by-step explanation:

Step-by-step explanation:

Given that Ed's string length is = 21.72 inches

And that Georgiana's string length is = 1/6 of Ed's string length

We need to find Georgiana's string length

Georgiana's string length = 1/6 of Ed's string length

And Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Which would bring  us that Georgiana's string length is = 3.62 inches
