Kyra Multiplied the number 56.8 by 10.
Answer:
RPM 1388.889
Horsepower 366.802
Step-by-step explanation:
We do not need to solve the equation for y = 0, which is nice. We can go directly to finding the maximum.
The maximum or minimum of ax^2+bx+c is always at x=-b/2a
with b = 25/45 and a = -1/5000 we get
x = -25/45 / (-2/5000) = 5/9 * 2500 = 12500/9 ≈ 1388.889
Now we only need to put that x into the equation (ideally in form of 12500/9 for accuracy) and we get the horsepower of ~366.802
Answer:
1/3
Step-by-step explanation:
12(multiplication problems) /36 (total problems 12+24)
12/36=1/3
Answer:
44 years old
Step-by-step explanation:
22 + 15x = 577....with x being the number of years
15x = 577 - 22
15x = 555
x = 555/15
x = 37......so in 37 years he will have them...and that would make Clark's age be (37 + 7) = 44 <===
How many jumping jacks does carla do in one day?
carla does 25 jumping jacks 3 times per day
25 + 25 + 25 = 75 jumping jacks per day
carla does 75 jumping jacks per day, how many will she do in 7 days?
7 x 75 = 525
Carla will do 525 jumping jacks in 7 days
