Answer:
4 : 7
Step-by-step explanation:
Given 2 similar figures the if the ratio of perimeters = a : b
The the ratio of areas = a² : b²
Here
ratio of areas = 16 : 49 , then
ratio of perimeters = : = 4 : 7
Answer:
you multiply xy by itself 4 times and then after you solve that you have to multiply that variable by itself 6 times.

Answer: The required rate = 0.64 per pounce.
Step-by-step explanation:
We are given that,
Postal service charge = $10.30 per pound.
As we know, 1 pound = 16 ounces.
So, Postal service charge = $10.30 per 16 ounces.
Postal service charge
Hence, the required rate = 0.64 per pounce.
Answer:
20%
Step-by-step explanation:
1.92 - 1.60 = 0.32
percentage increase = (0.32/1.60) * 100 =
0.2 * 100 = 20%
Try substituting those values, and you will see they do not fit either equation.
looking at the 2nd equation, y = x+2, so
x+2 = x^2+5x-3
x^2 + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5 or 1
so, y = -3 or 3
the solutions are thus (-5,-3)(1,3)
