Change 13/5 to a mixed number PLEASE HELP ME
Answer:
[tex] 2 \frac{3}{5} [/tex]
Step-by-step explanation:
13 = 5 + 5 + 3
[tex] \dfrac{13}{5} = [/tex]
[tex] = \dfrac{5 + 5 + 3}{5} [/tex]
[tex] = \dfrac{5}{5} + \dfrac{5}{5} + \dfrac{3}{5} [/tex]
[tex] = 1 + 1 + \dfrac{3}{5} [/tex]
[tex] = 2 \frac{3}{5} [/tex]
Answer:
[tex]2\frac{3}{5}[/tex]
The fraction consists of two numbers and a fraction bar: 13/5 The number above the bar is called numerator: 13 The number below the bar is called denominator: 5 The fraction bar means that the two numbers are dividing themselves. To get fraction's value divide the numerator by the denominator: Value = 13 ÷ 5
To calculate the greatest common factor, GCF: 1. Build the prime factorizations of the numerator and denominator. 2. Multiply all the common prime factors, by the lowest exponents. Factor both the numerator and denominator, break them down to prime factors: Prime Factorization of a number: finding the prime numbers that multiply together to make that number. 13 is a prime number, it cannot be factored into other prime factors; 5 is a prime number, it cannot be factored into other prime factors; * Positive integers that are only dividing by themselves and 1 are called prime numbers. * A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself. Multiply all the common prime factors, by the lowest exponents. But, the numerator and denominator have no common factors. gcf (13; 5) = 1Fraction 13/5 is a positive improper fraction (numerator > denominator).Mixed number = a whole number and a proper fraction, of the same sign. Proper fraction = numerator smaller than denominator.
13 ÷ 5 = 2 and remainder = 3 =>
13 = 2 × 5 + 3 =>
13/5 =
(2 × 5 + 3) / 5 =
2 + 3/5 =

An online shopping club has 11,200 members when it charges $7 per month for membership. For each $1 monthly
increase in membership fee, the club loses approximately 400 of its existing members. Write and simplify a function R
to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # members. monthly fee.
Answer:
Monthly revenue = R(x) = (11,200 - 400x) * (7 + x)
Step-by-step explanation:
Monthly revenue = Number of members * Monthly fee ......... (1)
Where;
Number of members = 11,200
Monthly fee = $7
For each $1 monthly increase in membership fee, we have
For 1 month, one dollar the decrease = 400 * 1 = 400
For 2 months, 2 dollar increase will lead to decrease of 400* 2 = 800 members
Therefore, for x months
Innrease in membeship fee or price increase = 7 + x
Decrease in the numbers of members = 400x
Substitute the values into equation (1), we have:
Monthly revenue = R(x) = (11,200 - 400x) * (7 + x)

[50 Points] The function [tex]y = 4.2\sqrt{0.28 x - 1}[/tex] models the annual number of visitors to an amusement park, where y is the number of visitors in millions and x is the number of years since 1975. Find the first year in which the amusement park had 12 million visitors?
Answer:
In 2008.
Step-by-step explanation:
The function:
[tex]y=4.2\sqrt{0.28x-1}[/tex]
Models the annual number of visitors to an amusement park, where y is the number of visitors (in millions) and x is the number of years since 1975.
We want to determine the first year in which the amusement park had 12 million visitors.
So, we will set y equal to 12 and solve for x. This yields:
[tex]12=4.2\sqrt{0.28x-1}[/tex]
By dividing both sides by 4.2, we acquire:
[tex]\displaystyle \frac{12}{4.2}=\frac{120}{42}=\frac{20}{7}=\sqrt{0.28x-1}[/tex]
And by squaring both sides:
[tex]\displaystyle \frac{400}{49}=0.28x-1[/tex]
Adding 1 to both sides produces:
[tex]\displaystyle \frac{400}{49}+1=\frac{449}{49}=0.28x[/tex]
And finally, dividing both sides by 0.28 gives us the approximation:
[tex]\displaystyle x=\frac{449}{49}\cdot \frac{1}{.28}=\frac{11225}{343}\approx32.72\approx33[/tex]
So, 33 years after 1975, the amusement park will have 12 million annual visitors.
Therefore, the first year in which the amusement park will have 12 million annual visitors is in the year 2008.

Regina had 30 meters of ribbon. She gave 2.7 meters of the ribbon to each
of her four friends and used the rest to tie some presents for her birthday
party. Each present required 75 centimeters of ribbon to tie. Find the
maximum number of presents Regina could tie.
Answer:
25 presents.
Step-by-step explanation:
First subtract 2.7(4) from 30.
30 - 2.7(4) = 19.2 meters
Now, convert 19.2 into centimeters.
There's 100cm in 1m, so 19.2 meters can be found by doing:
19.2 x 100 = 1920 cm.
Now, do 1920 divided by 75:
1920/75 = 25.6
Since you can't tie 0.6 of a present, you disregard that. So, she can tie 25 presents.

Which of the following best represents the rate of change for the number of gallons of fuel remaining with respect to the number of hours the truck has been driven?
-200 gal/h
-10 gal/h
0-1 gal/h
O-to galh
Answer:
-10 gal/h
Step-by-step explanation:
Rate of change for the number of gallons of fuel remaining and the number of hours the truck has driven is (-10) gallons per hour.
Option (2) will be be the answer.
Average rate of change of a function is given by the expression,
Average rate of change = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table given,
Two points are (0, 200) and (2.5, 175),
Average rate of change = [tex]\frac{175-200}{2.5-0}[/tex]
= [tex]-\frac{25}{2.5}[/tex]
= -10 gallons per hour
Therefore, average rate of change for the given table will be Option 2. (-10) gallons per hour.

In an arithmetic sequence, a3=15 and a8=0. What is the value of a5?
Answer:
a3=15 , n=3
a8=0, n=8
a5 = ?
an = a1+ (n-1)d
a3 = a1 + (3-1) d
a3=a1+2d
and a8 = a1 + (8-1 )d
a8= a1+ 7d
15 = a1 + 2 d-------1
0= a1 +7 d----------2
substacting eq 2 from eq 1
15= - 5d
- 5d = 15
divide by - 5
d = -3
putting the value of d in eq 1
15 = a1 + 7 (-3)
15 = a1 -21
adding 21 on both sides
a1-21+21= 15+21
a1 = 36
a5 = ?, n=5, d= -3, a1=36
a5 = 36 + (5-1) (-3)
= 36+(4)(-3)
= 36-12
= 24
