Recall the formula for area of a rectangle
A = LW
A = area of rectangle
L = length of rectangle = 6
W = width of rectangle
Also, recall the formula for Perimeter of a rectangle
P = 2L + 2W
P = perimeter of rectangle = 20
We have L=6 and P=20. Use these to solve for W in the perimeter formula.
P = 2L + 2W
20 = 2(6) + 2W
20 = 12 + 2W
8 = 2W
4 = W
Thus, L = 6 and W = 4. Use these measurements to solve for A.
A = LW = 6 * 4 = 24 in^2
Answer:
$40.20
Step-by-step explanation:
$7.50 per hour. Tim worked for 2 hours so you would do 2 timez 7.5 which is $15, the total he earned from mowing.
$6.30 per hour. Tim worked for 4 hours so you would do 4 times 6.3 which is $25.2, the total he earned from washing windows.
To get the total of how much he earned all together you add 15 and 25.2 and you get $40.2.
To get the answer we can use propotion
8 oil ---------------5 vinegar
x oil----------------7 vinegar
Crossmultiply now
5x=8*7
5x=56 :5
x=11.2 - its the answer
Answer:
1. 9 * 5 in.
2. 3 * 15 in.
Step-by-step explanation:
Volume = 1/3 * area of the base * height
120 = 1/3 * A * 8
So A = 120 / (8/3)
= 120 * 3/8
= 45 in^2.
So the dimensions of the base could be 9 * 5 in
or 3 * 15 in.
