Answer:
B. 273
Step-by-step explanation:
First we have to find the volume of the pencil box.
The volume formula for a rectangular prism is lwh (Length x width x height). Length (6 1/2) x Width (3 1/2) x Height (1 1/2) = 34.125 (Volume of the pencil box)
Next, we have to find the volume of the cube.
The volume formula of a cube is the same as the volume formula for a rectangular prism (lwh). However, a cube's side lengths are all the same. This means that the volume of the cube would be Length (.5) x Width (.5) x Height (.5) = .125
Last, we have to divide the volume of the pencil box by the volume of the cube.
34.125 / .125 = 273 or B.
<span>To find the answer we must remove the tips amount from the total amount, and then divide what remains by the numbers of hours he worked. So we have: HourlyRate = (400 - 253) / 28 <=> HourlyRate = 147/28 <=> HourlyRate = $5.25</span>
Answer:1/x^21y^12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let h be the number of hats Elliott makes and s be the number of scarves she makes.
Each hat uses 0.2 kilograms of yarn and each scarf uses 0.1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats. This is expressed as
h = 2s
The total number of hats and scarves that she wants to make is 20. This is expressed as
h + s = 20
Therefore, the system of equations that represents this situation are
h = 2s
h + s = 20
