Answer:
Option B. (0.7)n = 45.50
Step-by-step explanation:
If n represents the number of dollars she raised this year then as per question the equation will be (7/10)n = 45.50
(0.7)n = 45.50
Therefore option B. 45.50 = 0.7n is the answer.
To solve this problem you must apply the proccedure shown below:
As you can see in the figure attached above, the figure has a semicircle and a rectangle, then, you have that the perimeter is:
P=(18x2)+15+(15/2)(3.14)
P=36+15+23.55
P=74.55
Therefore, as you can see, the answer for this exercise is the last option, the option d, which is: d. 74.55
The answer is A. The domain is the set of all X values.
