x = 4/5
2/5=1/2x
Step 1: Flip the equation.
1/2x=2/5
Step 2: Multiply both sides by 2.
2*(1/2x)=2*(2/5)x=4/5

James spent $20.16 on comic books. Each comic book cost $0.72. After he read the comic books, James sold each one for $0.20 less than he paid for it. What is the total amount of money that James received from selling his comic books? Enter your answer in the box.
Answer:
$14.56
Step-by-step explanation:
Steps to answering this question
Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic Determine the selling price of the comic multiply the amount of comics bought by the selling pricethe total number of comics bought = total amount spent on comics / per unit price of comics
$20.16 / $0.72 = 28
selling price = 0.72 - $0.20 = $0.52
Total amount received = selling price x total comics bought
$0.52 x 28 = $14.56
Answer: the answer is 14.56

Step-by-step explanation:
Angle c and angle d are vertical angles with m angle c = -3x + 58 and m angle d = x - 2
Answer:
x = 15Step-by-step explanation:
Vertical angles means angles of the same measure.
m∠c = m∠d
-3x + 58 = x - 2 {subtract x and 58 from both sides}
-4x = -60 {divide both sides by (-4)}
x = 15

what is the length of the interior diagonal, d, rounded to the nearest hundredth cm
Answer:
The length of the diagonal, d is approximately 24.49 cm
Step-by-step explanation:
The question asks to find the length of the interior diagonal of a rectangular prism, also known as a cuboid;
The parameters of the prism are;
The height of the prism = 10 cm
The width of the prism = 10 cm
The length of the prim = 20 cm
The length of the given diagonal of the cuboid is found by Pythagoras's theorem from the height, 'h', of the cuboid and the diagonal of the base of the cuboid
Let 'l' represent the diagonal of the base of the cuboid, we have, by Pythagoras's theorem;
l² = ((20 cm)² + (10 cm)²) = 500 cm²
The length of the diagonal, 'd', by Pythagoras's theorem is given as follows;
d = √(l² + (²10 cm))
By plugging in the known value for 'l² = 500 cm²', we get;
d = √(500 cm² + (²10 cm)) = √(600 cm²) = 10·√6 cm
The length of the diagonal, d = 10·√6 cm ≈ 24.49 cm (by rounding to the nearest hundredth cm)

Answer:
C) 4(5c -2d)
Step-by-step explanation:
You would need to find the greatest commen factor in the equation.
it would end up being 4 since it is the biggest number that can divide between 8 and 20.
20/ 4 = 5
8/4 = 2
so you would leave the varibles since you can't take them out and put 4 on the outside of the parantheses.
4(5c -2d)

Option C: 4(5c -2d)

Determine whether the following equation represents a direct variation If it does, find the constant of variation
2x + 3y = 0
Given:
The equation is
[tex]2x+3y=0[/tex]
To find:
Whether the equation represents a direct variation. If it does, find the constant of variation.
Solution:
The general equation of direct variation is
[tex]y=kx[/tex] ...(i)
Where, k is the constant of variation.
The equation of direct variation is always true for (0,0).
The given equation is
[tex]2x+3y=0[/tex]
It can be written as
[tex]3y=-2x[/tex]
[tex]y=-\dfrac{2}{3}x[/tex] ...(ii)
For x=0,
[tex]y=-\dfrac{2}{3}(0)[/tex]
[tex]y=0[/tex]
The given equation is true for (0,0). So, it represents a direct variation.
On comparing (i) and (ii), we get
[tex]k=-\dfrac{2}{3}[/tex]
Therefore, the constant of variation is [tex]-\dfrac{2}{3}[/tex].
Executive leadership wants to survey employees at a grocery store that is open 24 hours a day. They are interested in getting surveys from people from every job title (cashier, stocker, manager, etc.) Which of the following uses systematic random sampling?
Survey 3 randomly chosen cashiers, then repeat that process with the stockers, managers, etc.
Randomly select 1 of the 3 shifts (morning, afternoon, or night), and survey all the employees who work that shift.
List all of the employees by their employee ID number. Have the computer randomly select 25 of the numbers, and survey those employees.
List all of the employees by their employee ID number. Survey the 11th person on the list (with the number 11 being randomly chosen), then survey every 10th person on the list after that.
Answer:
(D) List all of the employees by their employee ID number. Survey the 11th person on the list (with the number 11 being randomly chosen), then survey every 10th person on the list after that.

What is the area of the triangle whose vertices are (-4,0), (-10, 0) and (-7,-6)?
Step-by-step explanation:
From the point -10 to -4, there is a difference of 6 units. Base = 6
From the x-axis to the furthest point, there is a difference of 6 units. Height = 6
6*6 = 36
36/2 = 18
Area = 18

DeSean is sorting his toy car collection. ⅔ of the cars are sports cars. ¼ of the remaining toys are pick up trucks. All of the other toy vehicles are fire trucks. What fraction of the toys are fire trucks? If DeSean has 3 fire trucks, how many toys does he have in his entire toy car collection?
Answer:
Fraction of fire trucks = [tex]\frac{1}{4}[/tex]
Total number of toy cars = [tex]16[/tex]
Step-by-step explanation:
Fraction of sports car = [tex]\frac{2}{3}[/tex]
Fraction of remaining cars [tex]=1-\frac{2}{3}=\frac{3-2}{3} =\frac{1}{3}[/tex]
So,
Fraction of pick up cars = [tex]\frac{1}{4}(\frac{1}{3})=\frac{1}{12}[/tex]
Therefore,
Fraction of fire trucks = [tex]\frac{1}{3}-\frac{1}{12}=\frac{4-1}{12}=\frac{3}{12}=\frac{1}{4}[/tex]
That is Number of fire trucks = [tex]\frac{1}{4}[/tex] ( Total number of toy cars )
Number of fire trucks = 4
Total number of toy cars = [tex]4(4)=16[/tex]
