Answer:
The width of the skatepark is 100ft^2.
Step-by-step explanation:
Total area= 6000ft^2
The Formula for area= L x W (depends on the shape, but in this case that is the formula)
Length= 60 ft
Width = 100
60 x 100= 6000ft^2

Answer: m = 7 or -2
Step-by-step explanation:
Quadratic Formula! 
Polynomial Form: 
So in this example a: 1 b: -5 c: -14
You get:
m = 7 or -2
Check by plugging a value back in for m

True for both.
The formula is y=mx + b, or rearranged would be m= y/x -b/x.
Answer:
A: 336 km
B: 14 L
Step-by-step explanation:
Use a proportion
210 km / 5 L = x / 8L Cross multiply
8*210 = 5 x
1680 = 5x
x = 1680 / 5
x = 336 km
===============
210 /5 = 588/x Cross multiply
210x = 588 * 5
210x = 2940 Divide by 210
x = 2940/210
x = 14 L
You can have a maximum of 3 groups. This is due to the fact that you only have 3 sopranos to equally divide between groups. Over 3 you would have a group lacking a soprano so 3 is the greatest you can make it.
