Roger wants to have 400 copies of his resume printed. His local print shop charges $21.50 for the first 200 copies and $10 for every 100 additional copies. How much will the 400 copies cost, including a sales tax of 6%? Type numerical answer only.

Answers

Answer 1

Answer:

Answer:

$43.99

Step-by-step explanation:

400 copies = 200 copies + 100 copies + 100 copies

Price:

200 copies - $21.50

100 additional copies - $10

Total = $21.50+$10+$10=$41.50

Sales tax = 6%

Find 6% of $41.50:

$\$41.50\cdot 0.06=\$2.49$

So, Roger will pay

$\$41.50+\$2.49=\$43.99$

53/4 is equivalent to what fraction?

Answers

53/4

We can choose to multiply by any number, but I'll choose 2.
53*2 = 106
4*2 = 8

106/8 = 53/4

To make a fraction equivalent to another you can mutiply birth sides or divide both sides, let's mutiply. 53/4 x 2 is 106/8 so 53/4 is = to 106/8.

nanci is volunteering at the animal shelter .she wants to spend an equal amount of time playing with each dog.she has 145 minutes to play with all 7 dogs .about how much time can she spend with each dog?

Answers

Since Nanci has 145 minutes of play time with 7 dogs.

You do 145÷7 which gives you 20.7 we can't round to 21 cause that would be over limit. So she has roughly 20 minutes to play with each dog.

Answer:

$20(5)/(7)(minutes)/(dog)$

Step-by-step explanation:

we know that

To find how much time can Nancy spend with each dog, divide the total time by the number of dogs

$(145)/(7)(minutes)/(dogs)= (140)/(7)+(5)/(7)=20(5)/(7)(minutes)/(dog)$

rosa wants to use $20 to buy games. The inequality 2.50k+5.50≤20.00 represent the number of games, k, she can buy with her money. What is the greatest number of games Rosa can buy?

Answers

Answer:

The greatest number of games Rosa can buy is 5

Step-by-step explanation:

Let

k ----> the number of games, k, that Rosa can buy with her money

we have

$2.50k+5.50\leq 20.00$

solve for k

subtract 5.50 both sides

$2.50k\leq 20.00-5.50$

$2.50k\leq 14.50$

divide by 2.50 both sides

$k\leq 5.8\ games$

therefore

The greatest number of games Rosa can buy is 5

The area of a circle is found with the formula A = ?, where y represents 3.14. If a tile artistis placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet, what is
the approximate radius of the circle in feet?

Answers

The approximate radius of the circle in feet is 14.5

Solution:

Given, a tile artist is placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet,

We have to find what is the approximate radius of the circle in feet?

The area of a circle is found with the formula $\mathrm{A}=\mathrm{yr}^(2)$

where "y" represents 3.14 and r is radius. So now, according to given information,

$\begin{array}{l}{y r^(2)=658} \n\n {\rightarrow 3.14 * r^(2)=658} \n\n {\rightarrow r^(2)=209.55} \n\n {\rightarrow r=14.4759}\end{array}$

Hence, the radius of the given circle is 14.5 feet approximately

55% of what number is 77?

Answers

Set up an equation
Let the number be x.
55% of x = 77
"of" means multiply, so
55% * x = 77
55% is the same as 0.55 (% means divide by 100).
0.55x = 77
x = 140
