Answer: A

Step-by-step explanation:

The easiest way to solve this problem would to first figure out how long it takes for Mak to run 1 mile. To do that, you would need to divide 50 by 4 which would give you 12.5. So, it takes Mak 12 and a half minutes to run 1 mile. From there, you would need to multiply 12.5 by 10 to get 125. Finally, you wold need to simplify 125 minutes to hours giving you 2 hours and 5 minutes.

if y varies inversely with x and the constant of variation is 4.5 what are the values missing in the table
Alexxandr [17]
Seems like you forgot to attach the table.
For this reason, I will explain how to solve this question and you can apply using the numbers in your table.

We are given that:
y is inversely proportion to x. This means that as y decreases, x increases and vice versa.
Writing this into equation, we would get:
y = c/x where c is the constant of proportionality.
Now, we have the constant of proportionality given as 4.5.
This means that the equation that relates x and y is:
y = (4.5) / x

So, to fill in the table, we would substitute with the given x or y in the equation above and solve for the other variable.

Examples:
If given that x=2, then:
y = (4.5) / (2) = 2.25
If given that y=3, then:
3 = (4.5) / x
x = (4.5) / (3) = 1.5

Hope this helps :)

My circumference is 20 cm what is my diameter and radius?
Musya8 [376]

Answer:

The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.

The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.

Step-by-step explanation:

<h3>The diameter can be solved using: D = \frac{C}{\pi }</h3>

So, the first step would be : D = \frac{20}{\pi }

Then : D = 20 ÷ \pi

Finally, the answer will be : 6.36619772 cm. or 6.4 cm.

<h3>The Radius can be Solved using: r = \frac{c}{2\pi }</h3>

The first step would be : r = \frac{20}{2\pi }

Then : 20 ÷ 6.2831853071796 (2\pi)

Finally, the answer will be : 3.18309886 cm. or 3.2 cm.

Please help 1. another term for adding money to an account is
zzz [600]
<span>Payment. While payment is the sum of money paid in exchange for something either goods and services; the money can be credited (or added) into an account directly without making direct payment. We can also credit our account which is also payments. The most efficient way of building a savings is having a set minimum or percentage for saving whichever is greater. Sometimes we may need to save more than our "set minimum" especially when we earn more. The higher we earn the more our set minimum pales in comparison to what we ought to save. On the other hand if we have a set percentage it would also need to be raised higher when we earn more, but saving whichever is greater ensures that we make the best and most efficient savings decision at any period in time.</span>

the area of a rectangle is 42 square inches and one side is 12 inches long . find the perimeter of the rectangle
valentinak56 [21]
The area is one side times the other side
Make the other side x.
12x=42
x=42/12=3.5
The perimeter is 2x+2y where x and y are sides of the rectangle.
P= 2(3.5)+2(12)=7+24=31 inches
Hope this helps.
