What is the height in feet do not round up the answer

s344n2d4d5 [400]

Answer:

72.25 ft

Step-by-step explanation:

The function that models the height of the ball is

$h(t) = 68t - 16 {t}^{2}$

The maximum height occurs at:

$t = - \frac{b}{2a}$

$t = - \frac{68}{2 \times - 16} = \frac{68}{32} = 2.125$

We substitute t=2.125 to get:

$h(2.125) = 68(2.125) - 16(2.125) ^{2}$

$h(2.125) = 72.25$

The maximum height is 72.25 feet

How many strawberries did the family have for snacking on? Show your work

aleksandr82 [10.1K]

Answer:

62 went in the pie

31 are for snacking

Step-by-step explanation:

124 strawberries

Divide by 4

124/4 =31

1/4 went to the neighbor so 31 went to the neighbor

2/4 went into the pie so 2* 31 = 62 so 62 went into the pie

The total used 31+62 = 93

There were 124, so subtract the ones used

124-93=31

The rest are for snacking

There are 31 left for snacking
