The water level in Rick Lake changes at an average of -7/16 inch every 3 years.

Mathematics

Answer:

-7/48

Step-by-step explanation:

  1. Ok, so if there is a change of -7/16 inches every 3 years, then you just basically have to divide -7/16 inches by 3. And since you can't divide fraction and only multiply the reciprocal of a fraction you would say        -7/16 * 1/3 = -7/48.
  2. If you want to mark it on a number line, you would basically just find -7/16 and divide the distance from 0 to -7/16 into 3 portions and mark the 1st third of the distance your answer.

A vacuum had been marked down by 20% and solf for $250. What was the original price of the vacuum?
igomit [66]

Answer:

The original price was $312.50

Step-by-step explanation:

If the vacuum was marked down by 20%, that means it was sold for 80% of the full price. It was sold for $250, so 80% of the original price is $250.

Let's set up an equation.

80/100 of x = 250

0.8 • x = 250

Divide both sides by 0.8.

x = 312.50

The original price was $312.50

Hope this helps!

A boat traveled 36 miles in 1.5 hours and then 14 miles in 0.75 hours. what is the average speed of the boat?
jeka57 [31]
Speed=distance/time
You'll have to combine like terms.
36+14=50
1.5+0.75=2.25

And then you can use the formula.
50/2.25

Which statement describes the lines whose equations are y=1/3x+12 and 6y=2x+6
ICE Princess25 [194]
First, you should solve both equations for the same variable. Since the first one is already solved for y, solve the second equation for y as well.

6y = 2x + 6   Divide both sides by 6
y = \frac{1}{3}x + 1

You can see that both lines have a slope of \frac{1}{3}.
Lines that have the same slope are parallel lines.

Madison enjoys the game of golf. He knows that he will one-putt a green 15% of the time, two-putt 20% of the time, three-putt 35
scoundrel [369]

Answer:

The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.
