Answer:
c. metal
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it.

First calculate the change in y over the change in x:
by - ay -1 - 1 -2
———— = ——— = —— = 1
bx - ax -2 - 0 -2
The slope is 1:
Second set up the equation in y = mx + b form (m is your slope!) ...
y = (1)x + b
... and plug in either point you have used (A or B)
A(0,1)
1 = (1)(0) + b
1 = b
Now you have your equation: y = 1x + 1
Your final step is to plug in point C to solve for your missing variable:
y = (1)(5) + 1
y = 6
the value of H therefore is 6
The time that Carlene would have to wait to buy the desk is 4 years.
<h3>How long would it take before Carlene can afford to buy the desk?</h3>
When an amount of money is compounded, it means that both the amount that was invested and the interest accrued earn interest.
The formula that can be used to determine the time is
N = log(FV / PV) / log(e) / interest rate
log(500 / 400) / log(e) / 0.06 = 3.71 years = 4 years
