84 sq. ft of the wall has to be covered with paint or wallpaper.
Step-by-step explanation:
- Step 1: Find the area of wallpaper to be covered by calculating the area of the wall and subtracting the areas of the window, mirror and fireplace from it. All are rectangular in shape with are given by A = length × width
Area of the wall = 8 × 16 = 128 ft²
Area of the window = 18/12 × 14 = 1.5 × 14 = 21 ft² (since 1 ft = 12 in)
Area of the fireplace = 5 × 3 = 15 ft²
Area of the mirror = 4 × 2 = 8 ft²
- Step 2: Calculate the area to be painted or covered with wallpaper
Area of the wall to be covered with paint or wallpaper = 128 - (21 + 15 + 8)
= 128 - 44
= 84 ft²
You need to calculate miles per gallon.
Number of miles is just the difference in the odometer:
----> 23,927 - 23,672 = 255
Number of gallons = 16.5
MPG = 255/16.5 = 15.5
Answer:
2^170
Step-by-step explanation:
(16 x 4^3 x 8^8)^ 5
- start by converting it all to a common base
(2^4 x 2^3 x 2^24)^5
- calculate the product, by adding all the powers
(2^34)^5
= 2^170
Answer:
42.5 ft
Step-by-step explanation:
All you have to do is add all of the sides and the figure it out
So here we go
7.5 ft+24 ft+11 ft= 42.5 ft
Answer:
Ways of solving it
Step-by-step explanation:
20x - 5x = 65 - 5
as the numbers cross over the equality sign, their positive changes to negative and vice versa
15x = 60
Divide both side by the coefficient of X which is the number Infront of X
15x/15 = 60/15
X=4
OR
20x + 5 = 5x + 65
Dividing through by 5. All the numbers above are divisible by 5. 5 is also the LCM
4x + 1 = X + 13
4x - X = 13 - 1
3X = 12
X = 4
