There are 20 girls on the team so theres your first number then you add the girls and boys to get the total number of players (46) and write out your ratio
If one cup of sugar needs five cups water than divide the cup of water by five to get 1/5 cups sugar per cup of water :)
Answer:
Step-by-step explanation:
If the square has an area of 49 ft^2, then the length of one of its sides is
s = √(49 ft^2) = 7 ft, and its perimeter is P = 4(7 ft) = 28 ft.
As for the rectangle: let W and L represent the width and length, respectively. Then W*L = 24 ft^2 is the area. L = W + 2 ft. Therefore,
W(W + 2) = 24, or W^2 + 2W - 24 = 0, or (W +6)(W - 4) = 0. Thus, W = 4 ft.
The perimeter of this rectangle is P = 2W + 2L, or
P = 2(4 ft) + 2(6 ft) = 24 ft.
The square has the larger perimeter: It is 28 ft.

Original price = x
The original price of a pair of shoes was discounted 20%.
20% = 20/100 = 0.2
1 - 0.2 = 0.8
x * 0.8
Now they sell for $54.
x * 0.8 = 54
Solve to find x.
54 / 0.8 = x
x = 67.5
Convert that to currency.

domain is the numbes you are allowed to use for x
what I usually do is just find the numbers that aren't allowed in the domain. such numbers are numbers that cause a division by 0 or a squaer root of a negative number
given 
, there are no numbers that you can use for x that will cause a division by 0 or a square root of a negative number
so domain is all real numbers or D={x | -∞<x<∞}
