Answer:

N=2 hours

Step-by-step explanation:

She spent a total of 10 dollars.

Ice skate rental costs 4$

The fee per hour for skating is 3$ per hour

So minus 10$ by 4$, which is 6$

So now here at six and each fee per hour cost 3$, so therefore she skated for N= 2 hours.

How do i multiply fractions
Hatshy [7]
Best Answer:  <span> to multiply fractions you simply take the denominator of both fractions and multiply them, do the same to the numerator, and you have your answer.
ex.
2 5 10
-- * -- = ----
4 8 32

then, of course, you would need to simplify.

so the answer is

10(/2) 5
-------- = -----
32(/2) 16


To multiply mixed numbers, you need to convert them to improper fractions, multiply and then convert them back to a mixed number. For example:
2 1/2 x 5 1/3 = 5/2 x 16 /3

numerator 5 x 16 = 80 denominator 2 x 3 = 6

so now you convert 80/6 into a mixed number

80 / 6 = 13 and 2/6 or, reduced, 13 1/3. </span>

A ball is thrown into the air with an upward velocity of 36 ft/s. It’s height h in feet after t seconds is given by the function
777dan777 [17]

Answer:

Time taken for the ball to hit the ground back = 3.08 s

Step-by-step explanation:

h(t)= -16t² + 48t + 4

when will rhe object come back to hit rhe ground?

When the ball is at the level.of the ground, h(t) = 0.

0 = -16t² + 48t + 4

-16t² + 48t + 4 = 0

Solving the quadratic equation

t = 3.08 s or t = -0.08 s

Since the time cannot be negative,

Time taken for the ball to hit the ground back = 3.08 s

Hope this Helps!!!
