Answer:

Part 1) Option A. h(2) = 86.00 means that after 2 seconds, the height of the ball is 86.00 ft

Step-by-step explanation:

we have

h(t)=-16t^{2}+150

where

t ----> is the time in seconds after the ball is dropped

h(t) ----> he height in feet of a ball dropped from a 150 ft

Find h(2)

That means ----> Is the height of the ball  2 seconds after the ball is dropped

Substitute the value of t=2 sec in the equation

h(2)=-16(2)^{2}+150=86\ ft

therefore

After 2 seconds, the height of the ball is 86.00 ft.

164 is 55% of what number?<br><br> Please somebody help me
monitta
This is how you solve it; but first of all convert the percent into a decimal;55%= 0.55

0.55x = 164 (divide by 0.55 on both sides)
x = 164/0.55 
x = 298.18 (rounded to the nearest hundredth)
so 164 is 55% of 298.18(rounded)

Sajia has 30 Books in her library. she sold 9 books at the thrift store on Saturday. Write and solve and inequality to determine
ELEN [110]

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is 9 + x \leq 30

<em><u>Solution:</u></em>

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

<em><u>We can write a inequality as:</u></em>

\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }

9 + x \leq 30

Now moving 9 from L.H.S to R.H.S we get,

x \leq 30 - 9

On solving 30 - 9 = 21,

x \leq 21

So Sajia can sell 21 books she can sell if she comes back on sunday
