Job A will pay $32,448 per year. How much money would Sally be making per hour? Assume pay is based on fifty-two 40 hour weeks

borishaifa [10]

So Sally gets payed <span>$32,448 a year and gets paid the same amount each week. To figure how much she gets payed a week, divide her salary by 52 weeks since there are 52 weeks in a year. Then we divide how much she makes a week by 40 to see how much she gets payed an hour since she works 40 hours each week:
</span><span>32,448/52 = 624
624/40 = 15.6
Sally makes $15.60 an hour.
</span>

Hexagonal tiles of side 20 cm are used to tile a room which measures 6.25 m by 4.85 m. Assuming we complete the edges by cutting

ch4aika [34]

Answer: 292 tiles

Step-by-step explanation:

To find the number of tiles needed , we need to know the area of the hexagonal tiles and also the area of the room.

<u>Area of hexagon</u>

The area of hexagon is given as :

Area = $\frac{3\sqrt{3}}{2}$ $a^{2}$

Where a is the length of side.

Therefore:

A = $\frac{3\sqrt{3}}{2}$ $20^{2}$

A = $\frac{3\sqrt{3}}{2}$ X 400

A = (400 x 3 x $\sqrt{3}$ ) / 2

A = $\frac{2078.460969}{2}$

A = 1039.23 $cm^{2}$

Also to find the area of the room , we must first convert from m to cm

6.25 m = 6.25 x 100 cm

6.25m = 625 cm

4.85m = 485cm

Therefore: Area of the room = length x breadth

Area = 625 x 485

Area = 303125 $cm^{2}$

Therefore , the number of tiles needed = area of the room / area of hexagon

Number of tiles = 303125/ 1039.23

N = 291.6823032

Therefore , the number of tiles needed ≈ 292
