Answer:
d * 0.20 = x
Step-by-step explanation:
In order to calculate the total cost of the DVD's we first need to change the percentage of the discount that Miguel's manager is giving him into decimal format by dividing the percentage by 100 like so...
20 / 100 = 0.20
Now that we have the decimal value we can multiply it by the actual cost of the DVDss to find the total cost before taxes. Since we do not have the actual DVD cost we would make the following equation where x is the final total cost and d is the initial cost of the DVDs.
d * 0.20 = x

The teacher plans to organize them in such a way that each row has students with the same shirt color and all rows have the same number of students. Find the largest number of students in each row. There are 81 students in green shirts, 54 students in white shirts, and 27 in orange shirts. The
Answer:
27
Step-by-step explanation:
Given that:
Green shirt = 81 students
White shirt = 54 students
Orange shirt = 27 students
The largest number of student in each row : we need to obtain the greatest common factor for the three numbers.
Factors of :
81 : 1, 3, 9, 27, 81
54 : 1, 2, 3, 6, 9, 18, 27, 54
27: 1, 3, 9, 27
The greatest factor which is common in all three numbers is 27, hence, the largest number of student in each row should be 27

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (1, [tex]\frac{1}{2}[/tex] ), thus

Find the distance between thE two coordinates A(2,6),N(5, 10)
Using it's formula, the distance between the points A(2,6) and N(5,10) is of 5 units.
What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For this problem, the points are A(2,6) and N(5,10), hence the distance is given by:
[tex]D = \sqrt{(5 - 2)^2+(10 - 6)^2}[/tex]
D = sqrt(3² + 4²)
D = sqrt(25)
D = 5.

Erin drinks the same amount of milk every day. The equation below represents the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk. 16m=2d How long does it take for Erin to drink 1 gallon of milk?
Answer:
8 days
Step-by-step explanation:
We have that the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk is:
[tex] 16m = 2d [/tex]
Hence, the days that would take Erin to drink 1 gallon of milk is:
[tex] d = \frac{16m}{2} = 8m = 8*1 = 8 d [/tex]
Therefore, it would take for Erin 8 days to drink 1 gallon of milk.

A $55 pair of shoes was discounted 15 percent, making the sale price $46.75. The discounted price was then discounted again by 10 percent. Explain how you would find the final price of the shoes.
Answer:
$42.07
Step-by-step explanation:
If a pair of $55 shoes are discounted by 15%, then $55 (0.15) = 8.25. The pair of shoes were discounted by $8.25.
$55 - $8.25 = $46.75
If a $46.75 pair of shoes is further discounted by 10%, then $46.75 (0.10) = $4.675, or $4.68 rounded.
$46.75 - $4.68 = $42.07
Answer:
Sample response: The final price will be the discounted price multiplied by 100% — 10%. I could also multiply the discounted price by 0.10 and subtract that amount from the discounted price to get the final price.

Let us assume B to be at (x, y), hence:

The time that it takes a randomly selected job applicant to perform a certain task has a distribution that can be approximated by a normal distribution with a mean value of 110 sec and a standard deviation of 15 sec. The fastest 10% are to be given advanced training. What task times qualify individuals for such training? (Round the answer to one decimal place.) seconds or less
Answer:
The task times is [tex]x =90.77 \ s[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 110 \ sec[/tex]
The standard deviation is [tex]\sigma = 15 \ sec[/tex]
Generally the task times that qualify individuals for such training is mathematically represented as
[tex]P(X < x) = 0.10[/tex]
=> [tex]P(X < x) = P( \frac{X - \mu}{\sigma } < \frac{x - 110}{15} ) = 0.10[/tex]
Generally [tex]\frac{X - \mu}{\sigma } = Z (The \ standardized \ value \ of X )[/tex]
=> [tex]P(X < x) = P( Z < \frac{x - 110}{15} ) = 0.10[/tex]
Generally the z -score of 0.10 from the z-table is
[tex]z -score = -1.282[/tex]
So
[tex]\frac{x - 110}{15} = -1.282[/tex]
=> [tex]x =90.77 \ s[/tex]

A trapezoid has a base of 4.5 inches, a height of 6 inches, and an area of 21 square inches. The equation below can be used to determine b2, the length in inches of the second base of the trapezoid.
12(4.5+b2)(6)=21
Answer:
2.5in
Step-by-step explanation:
Given parameters;
Base = 4.5inches
Height = 6inches
Area = 21in²
Unknown:
b₂ = ?
Solution:
Formula for finding the area of a trapezium;
A = [tex]\frac{1}{2}[/tex][tex](b_{1} + b_{2} )[/tex] x h
Input the parameters and solve for b₂;
21 = [tex]\frac{1}{2}[/tex][tex](4.5+ b_{2} )[/tex] x 6
21 = 3(4.5 + b₂)
21 = 13.5 + 3b₂
21 - 13.5 = 3b₂
b₂ = 2.5in

Answer:
Yes
Step-by-step explanation:

Vertical Line Test: If a vertical line intersects a graph more than once, then the graph is not a function.
So if you draw a vertical line through that graph, it is only intersected once. Therefore, it is a function.
Jon caught four fish that weighed a total of 264 pounds. The kingfish weighed twice as much as the
amberjack and the white marlin weighed twice as much as the kingfish. The weight of the tarpon was 5
times the weight of the amberjack.
How much did each fish weigh?
Answer:
Amber jack 22 pounds
Tarpon 110 pounds
King fish = 44 pounds
White Marlin = 88 pounds
Step-by-step explanation:
Let the weight of the amber jack be x pounds
Kingfish weighed twice as much = 2 * x = 2x pounds
White Marlin weighed 2 times kingfish
= 2x * 2 = 4x pounds
Tarpon weighs 5 times amber jack = 5 * x = 5x
Add all together to give 264
5x + 4x + 2x + x = 264
12x = 264
x = 264/12
x = 22 pounds
Hence ;
Amberjack weighs 22 pounds
Tarpon = 5 * 22 = 110 pounds
Kingfish = 2 * 22 = 44 pounds
White Marlin = 2 times king fish = 2 * 44 = 88 pounds
