Answer:
75 mph
Step-by-step explanation:
In this kind of problem, "per" means "divided by". To find miles per hour, compute <em>miles divided by hours</em>:
(60 mi)/(4/5 h) = (60×5/4) mi/h = 75 mi/h
Nellie is going 75 miles per hour.
When it will hit the ground then height is 0
<span>h(t)=-16^2+250
-16^2+250=0
16t^2=250
t^2=250/16
t=3.95 seconds
i hope this is right</span>
Answer:
x=1
Step-by-step explanation:
Answer:
P(- 4, - 8 )
Step-by-step explanation:
The abscissa is the x- coordinate and the ordinate is the y- coordinate.
Here b = 2a , thus
a + 2a = - 12
3a = - 12 ( divide both sides by 3 )
a = - 4
and b = 2a = 2 × - 4 = - 8
P(- 4, - 8 )
The answer is 3 and one third!
20/4=5
(5*2)/3= 3 1/3
