Answer:
$742
Step-by-step explanation:
To solve this, you need to figure out what 6% of 700 dollars is and then add that to 700. The easiest way to find the percentage of a number is to set it up in the equation:
6/100 = x/700 where 6 is the percentage of 700 (out of 100 because you can only get up to 100 percent in this case) and x is 6 percent of 700. when you cross multiply, you get 100x = 4200. Then you divide both sides by 100 to get x by itself. This will give you x = 42 Add this to 700 for 742 as the total amount that will be paid. Sorry if this first half was a little confusing
Find the separate areas.
We have a triangle with base 5 cm and height 5 cm, calculate the area:

Plug in what we know:

Multiply:

Now for the two quarter circles, we know that if we put these two together we will end up with a semi-circle with radius 5 cm. The formula for the area of a circle is:

A semi-circle is half of a whole circle, so the formula for the area of it must be:

Now plug in what we know(use 3.14 to approximate for pi):

Simplify the exponent:

Multiply:

Now add this to the area of the triangle to find the approximate area of the entire figure(round to the nearest tenth):
Answer:
c
Step-by-step explanation:
You can find the unit rate when given a rate by setting up a proportion of the rate equal to how many per one.
40 miles per 2 hours = 20 miles per one hour.
20 miles/hour is a unit rate. (How many per one?)
A five percent tip of 81.24 would be 85.30, and rounded to the nearest ten dollars, it would be 90 even.
