Answer:80 mirror tiles will be needed to cover the wall is 80
Step-by-step explanation:
The dimension of one wall in living room is 8 feet by 10 feet. The wall is rectangular in shape. The area of a rectangle is expressed as
Length × width. The area of one wall in the living room would be
8 × 10 = 80 feet^2
The Williams family wants to cover one wall in their living room with 1-foot square mirror tiles.
The number of mirror tiles that they will need to cover the wall would be
80/1 = 80 mirror tiles.
First 3/4: this is actually 0.75. but the percent means we have to divide it by 100:
0.0075
3/25 is actually 0.12 (because it's equal to 12/100: i multiplied both numbers by 4)
and if it's a percent, again we "move to "move the point" or in other words divide by a 100:
0.0012 (think of dividing by 10 as of moving the coma to the left and adding zeros if there is noone to move)
the last one is equal to 55/100 (multiplied both by 5), so 11/20 % is 0.0055
I hope this was clear, let me know if you have questions!
Answer:
Rs 17 3/4
Step-by-step explanation:
Cost of 6 1/2 m = 115 3/8
Cost of 1 m = x
- x = 115 3/8 ÷ 6 1/2
- x = (115*8 +3)/8 ÷ 13/2
- x = 923/8 × 2/13
- x = 923/(4*13)
- x = 923/52
- x = 17 39/52
- x = 17 3/4
Cost of 1 meter is Rs 17 3/4
