katrin [286]
We know for our problem that Rachel makes $10 per hour. Sincex represent the number of hours that she works,  10x will be the total amount that she will make for working x hours. We also know that she sells bracelets for $5 each. Since y represents the number of of bracelets that she sells, 5y will be her total revenue for selling y bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of 10x and 5y must be equal or greater than 200:

10x+5 \geq 200

Find the surface area of the rectangle prism. 3cm 9cm and 6cm
lisabon 2012 [21]

Answer:

198 cm²

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

        = 2(99)

       = 198 cm²

Therefore, the area of the rectangular prism is 198 cm²
