Alex is practicing his dives at a pool. He dives from a dividing board that is 21 feet above the surface of the water. His dive

takes him 17 feet below the surface of the water. Alex says that the two distances are opposite, so his total dive distance is 22 + (-17) = 5 feet. Is Alex correct? How far did he travel if he is wrong?

Answer:

NO. Alex was wrong.  

The total dive distance is 21 + 17 = 38 feet

Step-by-step explanation:

Alex was wrong because his direction of diving is from above the water through the surface of the water to under the water.

So his direction of travelling is not opposite but the same.

Therefore the total distance traveled by Alex = distance traveled from the diving board to the water surface + distance traveled from the water surface to down below the water  

Distance traveled from the diving board to the water surface = 21 feet

Distance traveled from the water surface down below the water = 17 feet  

Total distance traveled by Alex = 21 feet + 17 feet

   = 38 feet.

Thus, Alex was wrong because the the total distance traveled by Alex was 38 feet.

Zack borrowed $1,087 for 12 months at 11 percent interest. If he must pay 11.00 per $100, what is Zack's monthly payment?
bagirrra123 [75]
Since we know that Zack must pay $11.00 per $100 monthly, we just need to divide the total amount of the loan, $1,087, by $100 to check how many times he must pay $11.00 each month:

\frac{1087}{100} =10.87

Now we know that he must pay $11.00 10.87 times each month, so the last thing we are going to do to find his monthly payment is multiply both quantities:
11.00*10.87=119.57

We can conclude that Zack's monthly payment is $119.57

What is 15 cm/year converted to inches per month? Round to the nearest tenth.
topjm [15]

Answer:

0.5 inches per month

Step-by-step explanation:

There are nearly 0.3937 inches in 1 cm, so

1 \ cm \approx 0.03937 \ in\\ \\15\ cm\approx 5.9055\ in

There are 12 months in the year, so'

15 centimeters per year is equivalent to

15 \ cm/year\approx \dfrac{5.9055}{12}\ in/month\\\approx 0.492125\ in/month\\\approx 0.5\ in/month\\\\

A candle on pauline’s dresser is 10 inches tall and burns at a rate of 0.75 inches per hour. how many hours will it take for the
Natalija [7]

Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:

h(t) = 10 - 0.75t

The height will be of 0.25 inches when h(t) = 0.25, hence:

0.25 = 10 - 0.75t

0.75t = 9.75

t = 9.75/0.75

t = 13 hours.
