It’s easy for the first one you add 10 each time
Answer:
I’m not sure what this question is asking, but I’ll write an equation of this circle you are describing. Here, the x coordinate of the center is h, the y coordinate is k, and radius is r in the equation : (x-h)^2+(y-k)^2=r^2, meaning the equation in this situation is the following: (x-2)^2+(y-8)^2=9
Step-by-step explanation:
<u>Given</u>:
The given graph represents the cost of the Kayak's rental per hour.
The coordinates are (2,30) and (3,45)
We need to determine the unit rate of renting per hour.
<u>Unit rate of renting:</u>
The unit rate of renting can be determined using the formula,

Substituting the coordinates (2,30) and (3,45), we get;

Simplifying, we get;

Dividing, we get;

Thus, the unit rate for renting a Kayak is $15 per hour.
Answer:

Step-by-step explanation:
<u>Operations with Fractions</u>
Mark sold
gallons of lemonade.
Regan sold
as much lemonade as Mark
We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:

Now we multiply:

Regan sold
gallons of lemonade
I think it’s compound interest
