Answer:
MULTIPLYING
Proper fractions: The first step when multiplying fractions is to multiply the two numerators.
Improper: The first step is to convert all the fractions into improper fraction.
Mixed: Multiply the numerators from each fraction to each other and place the product at the top.
DIVIDING
Proper: Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.
Improper: When you divide by a fraction, you want to cancel the second fraction by changing it to a 1
Mixed: To divide mixed fractions, you could first convert each to an improper fraction.
Step-by-step explanation:
:)
Answer:
Multiply
So, to multiply two mixed numbers, rewrite each as an improper fraction and then multiply as usual. Multiply numerators and multiply denominators and simplify. And, as before, when simplifying, if the answer comes out as an improper fraction, then convert the answer to a mixed number. Multiply.
Dividing
Change both mixed numbers to improper fractions. Invert the second improper fraction, then multiply it by the first fraction to get the answer. Reduce it if possible, and convert it to a mixed number if desired.

Answers
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

A theater company has raised $810.75 by selling 15 floor seat tickets. Each ticket costs the same.
Part A: Write an equation with a variable that can be solved to correctly find the price of each ticket. Explain how you created this equation. (5 points)
Part B: Solve your equation in Part A to find the price of each floor seat ticket. How do you know your solution is correct? (5 points)
Answers
Let's assume the price of each floor seat ticket is represented by the variable 'x'.
Since the theater company has raised $810.75 by selling 15 floor seat tickets, we can create an equation using the concept of total revenue. The total revenue is calculated by multiplying the price of each ticket by the number of tickets sold.
Therefore, the equation can be written as:
15x = 810.75
In this equation, '15x' represents the total revenue from selling 15 tickets at the price of 'x' per ticket, and '810.75' represents the total amount of money raised.
Part B:
To solve the equation 15x = 810.75, we need to isolate the variable 'x' on one side of the equation.
Dividing both sides of the equation by 15, we have:
x = 810.75 / 15
Evaluating the division, we find:
x ≈ 54.05
Therefore, the price of each floor seat ticket is approximately $54.05.
To confirm the solution, we can substitute the value of 'x' back into the original equation:
15 * 54.05 ≈ 810.75
This equation holds true, as the left side is approximately equal to the right side. Hence, we can conclude that the solution is correct.
I hope this helps! :)
Part A: 15x= $810.75. Part B: x= $54.05
The total money earned from 15 tickets is $810.75.
Assume, the money earned from selling 1 ticket is $x.
Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75
Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.
Using the equation above,
15x= $810.75.
Dividing both sides by 15,
We get,
x= $54.05
Hence, $54.05 is the price of each ticket.

How many total ounces of perfume are in the result
in each trial (each row?
Answers
Answer:
10 oz
Step-by-step explanation:
edge
The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.
Given to us,
For Trial 1,
A = 2 oz
B = 4 oz
C = 4 oz
Percentage of rose oil = 22%
weight of trail 1 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial 1 = weight of trail 1 x Percentage of rose oil in 1
= 10 oz x 22% = 2.2 oz
total ounces of perfume in trial 1
= weight of trail - Weight of rose oil in trial 1
= 10 - 2.2 = 7.8 oz
For Trial 2,
A = 4 oz
B = 2 oz
C = 4 oz
Percentage of rose oil = 27%
Total weight of trail 2 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial2 = weight of trail 2 x Percentage of rose oil in 2
= 10 oz x 27% = 2.7 oz
total ounces of perfume in trial 2
= weight of trial 2 - Weight of rose oil in trial 2
= 10 - 2.7 = 7.3 oz
For Trial 3,
A = 1 oz
B = 7 oz
C = 2 oz
Percentage of rose oil = 23.50%
Total weight of trail 3 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial 3= weight of trail 3 x Percentage of rose oil in 3
= 10 oz x 23.50% = 2.350 oz
total ounces of perfume in trial 3
= weight of trail - Weight of rose oil in trial 3
= 10 - 2.2 = 7.8 oz
Hence, The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.

whats the surface area?
Answers
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.
