So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
(13/15 - 7/10)
take lcm
<u>13*2 - 7*3</u> = 5/30*100= 50/3%
30
Step-by-step explanation:
Answer:
QR = 82.38 to nearest hundredth.
Step-by-step explanation:
As they are similar corresponding sides are in the same ratio.
So MN / QR = LM / QR
13/51 = 21/ QR
`3QR = 51*21
QR = 51*21/13
QR = 82.38
Step-by-step explanation:
A square's perimeter consists of 4 equal sides.
Therefore side of square park = 240m/4 = 60m.
You do 4 x 56 = 224. It’s just multiplication.
