Answer:
10 inches by 7 inches
Step-by-step explanation:
Let L and W represent the length and width of the rectangle, in inches. Then L = W + 3.
The perimeter is P = 2L + 2W, or P = 2(W+3) + 2W = 34 inches.
Solving for W: 2W + 6 + 2W = 34 inches, or
4W + 6 = 34 inches, or
4W = 28 inches, or W = 7 inches.
Given that L = W + 3, L = (7 inches) + 3 inches = 10 inches.
The length of the rectangle is 10 inches, and its width is 7 inches.
Answer:
3/4 6/8
Step-by-step explanation:
30/40 = .75
3/4= .75
6/8= .75
Answer:
1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.
2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased.
3. F = 4/R. This is inverse variation for the same reason as number 2.
4. m/n = 4. Direct variation. For the same reason as number 1.
5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.
6. R = cl/r². Joint variation.
7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r.
8. V= pir²h. Joint variation.
