Answer:
The equation is <em>y</em>=12<em>x</em>. It takes 24 minutes for the rock climber to get to 288 feet.
Step-by-step explanation:
Since we know there are 60 minutes in an hour, we can divide 720 by 60. This gives us 12. Therefore, for every minute, the rock climber gets 12 feet higher. Assuming <em>y </em>is the height in feet, and <em>x</em> is the time in minutes, we can create the equation <em>y</em>=12<em>x</em>. Now, to find how long it takes to get to 288 feet, we will substitute y with 288.
288=12<em>x</em>
288/12 = 12x/12
24 = x
Now, we have time in minutes that it takes to get to 288 feet.
Hope this helps!

I already did the test.
0.4 is false and 2.5 is true, bigger than 1 means increase.
Answer:
342 grams of sugar are needed.
Step-by-step explanation:
This really should be in chemistry. Math types may not know any chemistry.
Step One
Find the number of moles needed in a solution of the givens.
<em><u>Givens</u></em>
V = 2.00 L
C = 0.500 moles / Liter
<em><u>Formula</u></em>
n = C * V
<em><u>Sub and Solve</u></em>
n = 2 * 0.5 = 1 mole
Since you need just 1 mole, the answer is 342 grams of sugar are needed to put into a solution of 2 Liters with a concentration of 0.500
The answer is to 3 decimal places so 342 is the answer.
