7 and 19 are both prime numbers.
Factors of 7
1 * 7 = 7
7 * 1 = 7
factors are 1 and 7
Factors of 19
1 * 19 = 19
19 * 1 = 19
factors are 1 and 19
GCF = greater common factor
So GCF is 1 because there is no greater common number in the 7 and 19
Answer:
The ratio is 5:8.
Step-by-step explanation:
Since we are looking for books and tennis balls, we have to look at how many there are. There are 5 books and 8 tennis balls. We're looking for the ratio of books to tennis balls, so it has to be in that order. 5:8

Using an exponential function, it is found that you would have $10,240 after 18 years.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
Considering the initial value of $2,500, and the growth rate of 60% every 6 years, the equation is given by:

Hence, after 18 years, the amount is given by:

Answer:
58 minutes.
Step-by-step explanation:
From the question, Karen worked on the model in two windows;
1) 11.13 AM - 11.54 AM = 41 minutes
2) 1.29 PM - 1.46 PM = 17 minutes.
Hence, the total amount of time Karen spent working on the Shuttle model is:
41minutes + 17minutes = 58 minutes.
Answer:
36
Step-by-step explanation:
EF = is 1/3 of 15
Since the triangles are similar, then the perimeters are similar.
The perimeter of EDF is 12
The perimeter of ABC should be 3 times as large.
3*12 = 36
The perimeter of ABC = 36
