A manager needs to order company shirts for each employee. She was quoted the following rates. If she orders 75 shirts and passe

docker41 [41]

The answer is B.$7.47.

Let's first calculate how much in total 75 shirts cost:
- first 19 (less than 20) cost $10: 19 * $10 = $190
- the next 30 cost $8: 30 * $8 = $240
- the rest (26 = 75 - 19 - 30) cost $5: 26 * $5 = $130

So, in total 75 shirts cost $560:
19 * $10 + 30 * $8 + 21 * $5 = $190 + $240 + $130 = $560

Since 75 shirts are ordered, there must be 75 employees, so each employee must pay $7.47:
$565 ÷ 75 = $7.47

Evaluate. -|-7 + 3| <br> 4<br> -4<br> -10

agasfer [191]

Your answer is 4

You have to use the distribute property and distribute the - to the -7 and the 3

The -7 will become and the 3 will become -3

Then you add those together and when you add a negative to a positive you basically subtract

So 7+-3 is 4

A is your answer

When you roast coffee, it loses 12% of its weight. how much fresh coffee do you need in order to get 14 2/25 lb of roasted coffe

Komok [63]

Answer:

16 lb of fresh coffee.

Step-by-step explanation:

Let x pound be the amount of fresh coffee needed.

100 - 12 = 88% is equivalent to 14 2/25 of roasted coffee.

By proportion x = 14 2/25 / 88/100

= 352 / 25 * 100/88

= 35200 / 25 * 88

= 16 lb (answer).

Lin's teacher uses the box to store her set of cubes with an edge length of one half inch. if the box is completely full, how ma

nlexa [21]

Answer:

448 cubes

Step-by-step explanation:

Volume of cubes fitted in the box will be equal to the cumulative volume of the cubes.

Since, volume of a cube = (Side)³

Side of the cube = $\frac{1}{2}$ inch

Therefore, volume of the cube = $(\frac{1}{2})^3=\frac{1}{8}$ inches

Volume of the storage box = 56 cubic inches

Since, number of cubes fitted in the storage box = $\frac{\text{Volume of the storage box}}{\text{Volume of one cube}}$

= $\frac{56}{\frac{1}{8}}$

= 56 × 8

= 448 cubes

Therefore, number of cubes fitted in the storage box = 448
