Answer: 100 rides are needed to break even.
Step-by-step explanation:
C(x)=15x+2000 - x is the number of rides.
R(x)=35 x , where x is the number of rides
35x=15x+2000
35-15x=2000~subtract 15x from both sides~
20x=2000 ~simplify~
x=2000/20 ~dividing both sides by 20~
x=100
Answer:
1 and 3/5
Step-by-step explanation:
4/5+4/5=8/5
8÷5
=1 3/5
Answer:
Surface area of a solid figure can be found by multiplying the area of the base by the height of the figure.
<em><u>it's false </u></em>
Step-by-step explanation:
H = 151t - 16t²
The height of the ball when it return to the ground will be 0
0 = 151t - 16t²
The zero product property is that when two numbers are being multiplied and the product is 0, one of them must be equal to 0. Therefore, we can factorize this equation:
16t² - 151t = 0
t(16t - 151t) = 0
By the zero product property:
t = 0 or 16t - 151 = 0
So t = 0 or t = 9.44 seconds
The first solution is before he releases the ball and the second is when the ball comes back to the ground. Thus, the ball's air time is 9.44 seconds.
Answer:
5
Step-by-step explanation:
26 × 10 ÷ 100 = 52 · x ÷ 100
260 = 52 · x
x = 5
