4 0

Answer:

{1.2}^{n}  \times 2.5

Step-by-step explanation:

it's simple my dear friend.

first, she runs 3 miles per week.

so in

{a}^{(n - 1)}   \times b

b is 3. the initial value.

increasement by 20% means she runs 1.2 times than before.

\frac{100 + 20}{100}  =  \frac{120}{100}  =  \frac{12}{10}  = 1.2

then a=1.2

so we have now:

{1.2}^{(n - 1)}  \times 3 \\  =   {1.2}^{n}  \times  \frac{3}{1.2}   \\  =  {1.2}^{n}  \times 2.5

and we got it!

Raul drove 80 miles. This represents 50% of his entire trip. What is the total number of miles in Raul's trip?
Dafna11 [192]
If 80 miles is 50% of his trip, then you know that 80 miles is only HALF of his entire trip. To get the distance Raul traveled in total, simply double the 80 miles. This would be 160 miles. 
Raul traveled a total of 160 miles in his trip.

svetlana [45]

Answer:

C. The mean is 111.9F and the median is 114.5F.

Step-by-step explanation:

The mean is 111.9 given that (105 + 113 + 122 + 121 + 116 + 118 + 107 + 93)/8 = 111.875 which can be rounded to 111.9 F.

Organizing the values we have:

[93, 105, 107, 113, 116, 118, 121, 122]

We find that the median is going to be between 113 and 116. Therefore:

(113 + 116) / 2 = 114,5

Therefore, the correct answer is option C.

tester [92]

Answer:

<u>The rate the swimming pool is filled is 9 gallons of water per minute</u>

Step-by-step explanation:

Let's review the information provided by Ronald to us to help him to find the answer to the question:

Time it takes to fill the swimming pool = 8 minutes

Amount of water the swimming pool can hold = 72 gallons

2. At what rate does the swimming pool fill, in gallons per minute?

Rate the swimming pool is filled = Amount of water the swimming pool can hold /Time it takes to fill the swimming pool

Replacing with the real values, we have:

Rate the swimming pool is filled = 72/8 = 9 gallons of water per minute
