Answer:

2nd and 3rd choices

Step-by-step explanation:

use h(t) = h(0) + v(0)t + at^2/2

Now h(0) = 18, v(0) = 0, a = -9.8

so h(t) = 18 - 4.9 t^2

Solve h(t) = 18 - 4.9 t^2 = 0

Get t = 1.92 sec

Martha works in a toy shop and earns $44 per day. She earns an extra $2 for each toy she sells. If Martha wants to earn at least

pantera1 [17]

Martha's total earnings is the sum of her fixed pay pay day and the extra she gains based on the number of toys she sold. Her total earnings may be expressed as,

44 + 2n

Since she desires to earn $80 or more, the inequality is expressed as

44 + 2n ≥ 80

Solving for n from the inequality,

n ≥18

Thus, the answer is the first choice.

<u>Solution-</u>

Bill bought a computer and a printer for a total of $650.

Let p stand for the cost of the printer, so

$\text{Cost of the computer + p} =650$

$\Rightarrow 525+p=650$

$\Rightarrow p=650-525=125$

Bonnie ordered 27 products from one company

Let m stand for the number of missing items

$\text{Number of item she got + m} =27$

$\Rightarrow 19+m=27$

$\Rightarrow m=27-19=8$

Terri bought four lipsticks for a total cost of $20

Let l stand for the cost of one lipstick.

$Price\ of\ one\ lipstick \times I=20$

$\Rightarrow 4 \times I=20$

$\Rightarrow I=5$

Each survey takes him about 10 minutes to complete

Let h stand for the number of hours

$Tota\l time\ taken\ = Time\ taken\ for\ 1\ survey\ in\ hours\times no.\ of\ survey$

$Total\ time\ taken\ =\frac{10}{60} \times 30 = 5 hours$

Andy played golf three times during his vacation. His scores were 92, 87, and 88.

Let A stands for the average.

$Average \ score=A= \frac{Score_1+Score_2+Score_3}{3} =\frac{92+87+88}{3}=89$

Tickets to a local basketball team’s games cost $12 each. Brendon and Ed each bought tickets to four games.

Total tickets = 2×4=8 (∵ They each bought 4 tickets)

(Let t stand for the amount spent on tickets.

$Amount\ spent\ on\ tickets\ =price\ of\ 1\ ticket \times total\ ticket}$

$\Rightarrow t=12 \times 8=96$

If you blow air into a cup of water, does the water level change?

lisabon 2012 [21]

Since you are blowing warm air, the air molecules are moving fast so it makes the water expand. By the way that's what happens to a thermometer and I think this is a science question :)

This might be right
