Jim has a box in the shape of a rectangular prism. The area of the base of the box is 48 square inches. The volume of the box is 144 cubic inches. let h= the height of Jim's box. Write and solve an equation you can use to find the height of Jim's box.

Answers

Volume = v, height = h, area of the base= B
v=h•b
144=h•48
h=144/48
h=3 inches

Harper works at an electronics store as a salesperson. Harper earns a 6% commission on the total dollar amount of all phone sales she makes, and earns a 5% commission on all computer sales. Harper made a total of $2600 in sales and earned $137 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Harper made and the dollar amount of computer sales she made. Define the variables that you use to write the system.

Answers

Answer:

The system of equations are

x + y = 2600 …….equation (1)

and, 6x + 5y = 13700 ……equation (2)

Explanation:

Let x = amount of sales of phone;

y = amount of sales of computer

For phone, 6% of sales is 6% of x, or 6% * x = 0.06x.

Similarly for computer,

5% of y = 0.05y

Given the total sales; x + y = 2600

And commission; 0.06x + 0.05y = 137; or 6x + 5y = 13700

Therefore the system of equations are

x + y = 2600 …….equation (1)

6 x + 5 y = 13700 ……equation (2)

clara and her friends are planning s trip to a paintball park find the cost of lunch and the cost of each paint ball what would be the cost for 400 paintballs and lunch

Answers

Final answer:

To find the cost of lunch and the cost of each paintball, we need more information. If we have the cost of lunch and the cost of one paintball, we can calculate the total cost for 400 paintballs and lunch. Let's say the cost of lunch is $10 and the cost of one paintball is $2. The total cost for 400 paintballs would be 400 x $2 = $800. Adding the cost of lunch, the total cost for 400 paintballs and lunch would be $800 + $10 = $810.
