19 = 1/2 g t²
Multiply each side by 2 :
38 = g t²
Divide each side by ' g ' :
t² = 38/g
Square root each side :
<em>t = √(38/g)</em>
Answer:
$77
Step-by-step explanation:
First, let's find the total money they have raised.
$157 + $366 = $523
They have raised $523 in the first two weeks.
They want to raise a total of $600, so we subtract the amount they already raised from the total they want to raise.
$600 - $523 = $77
They need to raise $77 more.

Answer:
3100ft
Step-by-step explanation:
There are 2 sides to the prism that have an area of 50ft * 10ft or 500ft. The total of those will be 500ft * 2 or 1000ft. There are 2 more sides to the prism that have an area of 30ft * 10ft or 300ft. The total would be 300ft * 2 or 600ft. Then the last two sides to the prism have an area of 50ft * 30ft or 1500ft. Since we're imagining this prism to be a house, you can't paint the floor (well, I guess you could but I think they want us to leave that part out because you can't pick the house up to paint the bottom that would be ridiculous). So the surface area is each area added, or 1000ft + 600ft + 1500ft = 3100ft.
A.) There are many different expressions that can be equivalent to 4/2 and -2/3, but you just need one expression. <em>4/2 is equivalent to 2/1 and -2/3 is equivalent to -4/6.</em>
Reason:
There are two ways you can find a fraction equivalent to another.
1.) First one is by reducing the fraction if possible.
Example: <em>5/10=1/2, 10/30=1/3, 9/16=3/4.</em>
<em />
2.) The second one is by multiplying the numerator and the denominator by the same number, usually by 2 or 3.
Example: <em>1/2 x 2/2 = 2/4, </em> so <em>1/2= 2/4.</em> Another: <em>1/3 x 3/3 = 3/9</em>, so <em>1/3=3/9</em>
<em>That said, 4/2 = 2/1 because it was reduced. While -2/3 = -4/6 because it was multiplied by 2/2. </em>
