Step-by-step explanation:
5d-6*(3cd) = 15cd^2-28cd
Set it up like this, going from words on the page to letters and variables:
-3(2x+5) = -57. Twice a number is 2x, increased by 5 is 2x+5, and that is multiplied by -3 to get a total of -57. Distribute the -3 into the parenthesis to get -6x - 15 = -57. Move the 15 over by addition to get -6x = -42. Divide both sides by -6 to get that x = 7
Total moving cost is $2176.875 including tax.
Step-by-step explanation:
Cost for loading/unloading service= $95 per hour
Total cost for loading/unloading services = 95 x 6
= $750
Cost for packing/unpacking service= $80 per hour
Total cost for packing/unpacking= 80 x 5
= $400
Trunk rent = $5 per mile
Total distance= 175miles
Total rent = 175 x 5
= $875
Total cost = 750 + 400 + 875
= $2025
Tax = 2025 x (7.5/100)
Tax = $151.875
Total cost including tax = 2025 + 151.875
= $2176.875
Total moving cost is $2176.875 including tax.
Answer:
10.5 squared centimetres.
Step-by-step explanation:
First, find the area of that sector. We are already given that the circle is 154 squared centimetres.
We are given 90 degrees (or one fourth of the circle). Thus, divide 154 by 4 to get the area of the sector (the white area).
The area of the sector is 154/4 or 38.5
We then need to find the area of the square. After that, we can subtract the sector area (the white area) from the area of the square (the total area) to find the area of the shaded section.
The area of the square is 7*7 or 49.
Thus, the shaded portion will be 49-38.5 or 10.5 squared centimetres.
