What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The fastest pizza box folder can assemble 8 pizza boxes in 21 seconds.
The rate of assemble = 21/8 seconds per pizza
The time is taken to assemble 20 pizza boxes:
= (21/8)x20
= 420/8
= 52.5 seconds
Thus, the time taken is 52.5 seconds to assemble 20 pizza boxes if the fastest pizza box folder can assemble 8 pizza boxes in 21 seconds.

Find the values of x and y
Answer:
x = 8
y = 21
Step-by-step explanation:
The angle (7x + 12)° and the angle (12x-28)° are alternate interior angles and so has got the same measurement
7x + 12 = 12x - 28
12 + 28 = 12x - 7x
40 = 5x divide both sides by 5
8 = x
The sum of angle (12x - 28)° and (9y - 77)° must be equal because they make a straight line with the measure of 180°
12x - 28 + 9y - 77 = 180 we already found the value of x as 8 so let's rewrite the equation
12 × 8 - 28 + 9y - 77 = 180
96 - 28 - 77 = 180 add like terms
9y - 9 = 180
9y = 189 divide both sides by 9
y = 21

Functions f, g, and h are defined as follows: f(x) = x +1, g(x) = x^2 +1, and h(x) = x^3 +1.
(a) Find the inverse of function g(x).
(b) Find f(h(-2))
(c) Find g(f(3)
Answer:
a. let the gx be x
g(x) = x^2+1
or, x^2+1=y
or, x^2= y-1
:. x=2 root y-1
inter changing the relation of xand y

b) n = -5
C) 5.7 n + 4.1 = 2.96
c) n = -0.2
D) n/8 + 1/2 = -3 1/2
d) n = -3.2
Thank you..
Answer:
(A) and c
(B) and a
(C) and d
(D) and b
Step-by-step explanation:
these are from the calculations i got, what you do is minus the two answers you have to find n
For equations,
A) -1.4 n + 2.1 = 6.58 then n = 3.2
B) 4 n - 2 3/4 = -22 3/4 then n=24
C) 5.7 n + 4.1 = 2.96 then n=-0.2
D) n/8 + 1/2 = -3 1/2 then n=24
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A) -1.4 n + 2.1 = 6.58
Subtract 2.1 on both sides
1.4n=6.58-2.1
1.4n=4.48
Divide both sides by 1.4
n=3.2
B) 4 n - 2 3/4 = -22 3/4
4n-11/4=-85/4
4n=85/4+11/4
4n=96
Divide both sides by 4
n=24
C) 5.7 n + 4.1 = 2.96
5.7 n = 2.96- 4.1
5.7n=-1.14
n=-0.2
D) n/8 + 1/2 = -3 1/2
n/8 = -3 1/2-1/2
n/8 = -5/2-1/2
n/8 = -3
n=-24
Hence, equations A) -1.4 n + 2.1 = 6.58 then n = 3.2
B) 4 n - 2 3/4 = -22 3/4 then n=24
C) 5.7 n + 4.1 = 2.96 then n=-0.2
D) n/8 + 1/2 = -3 1/2 then n=24

What is the mean?
Answer:
The mean is 15.25.
Step-by-step explanation:
First, we need to be sure we know that the mean is the average number in the group of numbers. That doesn't mean the most repeated or the number in the middle. Simply, the average.
To find the mean of a group of numbers you simply add them all together and divide by the number of numbers. So, let's solve.
12 + 14 + 17 + 18
= 61 ÷ 4
= 15.25
So the mean of 12, 14, 17, and 18 is 15.25.

If two 12-sided dice are rolled, what is the probability that both numbers will be even?
ANSWERS:
1/2
73/144
1/4
71/144
The probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
Given that two 12-sided dice are rolled and need to calculate the probability of getting an even number.
Number of favorable outcomes = 6 x 6 = 36
Number of sample = 12 x 12 = 144
The probability of getting an even number will be calculated as:-
Probability = Number of favorable outcomes / Number of sample
Probability = 36 / 144
Probability = 1 / 4
Therefore, the probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.

At a high school football game, admission is $5 for students and $10 for non-students. There were 500 people at the first game, and the school made $4,000 from admissions. In this activity, you will find the number of students and non-students at the game.
Please write the two equations algebraically and then solve :)
Answer:x = 200 students
y = 300 non-students
Step-by-step explanation:
5x + 10y = 4000
x + y = 500
Set y = 500-x
5x + 10(500-x) = 4000
5x + 5000-10x
-5x + 5000 = 4000
-5x = -1000
x = 200 students
y = 300 non-students
Let's double checks
5(200) + 10(300)
1000 + 3000 = 4000
