y = 73x
y = 43x
y = 34x
y = 37x
Answer:
y=3/7x
Step-by-step explanation:
The equation from the given graph is y=3/7 x. Therefore, option D is the correct answer.
What is scatter plot?Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.
From the given figure,
The slope of a line is 3/7 and the y-intercept is c=0
Substitute m=3/7 and c=0 in y=mx+c, we get
y=3/7 x+c
y=3/7 x

Given the following equation, solve for the easiest variable.
3x + y = -6
Answer:
Let's solve for x.
3x+y=−6
Step 1: Add -y to both sides.
3x + y + −y = −6 + −y
3x = − y − 6
Step 2: Divide both sides by 3.
3x / 3 = − y −6 / 3
x = − 1 / 3 y −2
Answer:
x = − 1 / 3 y −2

which of the following is the solution to the equation 25(z-2 )= 125?
A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5
Answer:
The answer is z = 7.
Step-by-step explanation:
1) Divide both sides by 25.
[tex]z - 2 = \frac{125}{25} [/tex]
2) Simplify 125/25 to 5.
[tex]z - 2 = 5[/tex]
3) Add 2 to both sides.
[tex]z = 5 + 2[/tex]
4) Simplify 5 + 2 to 7.
[tex]z = 7[/tex]
Thus, the answer is z = 7.
Find the area of a rectangle with side lengths 5 /8 ft. And 1/ 3 ft. A 1-foot by 1-foot square is shown. The square is divided into 8 rows and 3 columns. Therefore, there are a total of 24 equal-sized cells inside the square. A. 5 /11 ft 2 B. 1 11/ 12 ft 2 C. 6/ 11 ft 2 D. 5 /24 ft 2
Answer: 5/24 ft²
Step-by-step explanation:
To find the the area of a rectangle with side lengths 5/8 ft and 1/3 ft, we need to know that the area of a rectangle is gotten by multiplying the length by the width.
In this case, the area of the rectangle will be:
= 5/8 × 1/3
= 5/24 ft²
A spinner used in a board game is divided into 8 equally sized sectors. Three of these sectors indicate that the player should move his token forward on the board, two of these sectors indicate that the player should move his token backward, and the remaining sectors award the player bonus points but do not move his token on the board. The total area of the sectors that do not allow the player to move his token is 35.9 inches squared. What is the radius of the spinner
Answer:
5.52 inch
Step-by-step explanation:
Recall :
Area of Sector : θ/ 360 * πr²
Sectors that do not allow movement : (8-3-2) = 3
Total sectors = 8
θ/ 360 = 3/8 ; Area = 35.9
Radius = r
35.9 = 3/8 * π * r²
35.9 / (3/8 * π) = r²
30.472866 = r²
r = √30.472866
r = 5.52 inch
The radius of the spinner is 5.520 inch whose [tex]\frac{3}{8}[/tex] sector area is 35.9 inches square.
It is given that the spinner used in a board game is divided into 8 equally sized sectors. three sectors indicate that the player should move his token forward on the board, two sectors indicate that the player should move his token backward, and the remaining sectors award the player bonus points but do not move his token on the board and its area of the sector is 35.9 inches square.
It is required to find the radius of the spinner.
What is the area of the sector?The region enclosed by the two radii of a circle and the arc is known as a sector's area. In other words sector area is a portion of the circle's area.
We know the formula of sector area (A):
[tex]\rm A= \frac{\theta}{360 \°} \pi r^2[/tex] Where 'r' is the radius of the circle and [tex]\rm \theta[/tex] is in degree
The remaining sectors = ( Total sectors - Three sectors - Two sectors)
= ( 8 - 3 - 2) ⇒ 3 sectors indicate the player do not move his token
Total sector = 8
[tex]\rm \frac{\theta }{360 \° } = \frac{3}{8} \ when \ A = 35.9 \ inches^2[/tex]
Putting these values in the above formula, we get:
[tex]\rm 35.9 = \frac{3}{8} \pi r^2\\\rm 35.9\times 8 = 3\pi r^2\\\rm 287.2 = 3\pi r^2\\\\\rm \frac{287.2}{3} = \pi r^2\\\\\rm 95.733= \pi r^2\\\rm 30.4728 = r^2[/tex]Where [tex]\rm \pi[/tex] = 3.14159
[tex]\sqrt{30.4728} = r\\\rm 5.520= r \\\rm or = 5.520 \ inch[/tex]
Thus, the radius of the spinner is 5.520 inch.

The cargo hold of a truck is a rectangular prism measuring 18 feet by 13.5 feet by 9 feet. The driver needs to figure out how many storage boxes he can load. Choose true or False for each statement.
Answer:
B
Step-by-step explanation:
The solution is
Option A - True
The volume of the rectangular cargo is 2187 feet³
Option B - True
The volume of the rectangular cargo is 2187 feet³
Option C - True
The volume of the rectangular cargo is 2187 feet³
Option D - True
The volume of the rectangular cargo is 2187 feet³
What is the Volume of a Rectangle?
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
Let the cargo hold be a rectangular prism
Now , the dimensions of the rectangular prism is
18 feet x 13.5 feet x 9 feet
And , the Volume of Rectangle = Length x Width x Height
Substituting the values in the equation , we get
Volume of Rectangle = 18 x 13.5 x 9
Volume of Rectangle = 2187 feet³
a)
The number of boxes = 6
The dimensions of the cargo be = 9 feet x 4.5 feet x 9 feet
So , the volume of the cargo = number of boxes x 9 x 4.5 x 9
On simplifying the equation , we get
Volume of the cargo = 6 x 364.5
Volume of the cargo = 2187 feet³
b)
The number of boxes = 81
The dimensions of the cargo be = 3 feet x 3 feet x 3 feet
So , the volume of the cargo = number of boxes x 3 x 3 x 3
On simplifying the equation , we get
Volume of the cargo = 81 x 27
Volume of the cargo = 2187 feet³
c)
The number of boxes = 24
The dimensions of the cargo be = 4.5 feet x 4.5 feet x 4.5 feet
So , the volume of the cargo = number of boxes x 4.5 x 4.5 x 4.5
On simplifying the equation , we get
Volume of the cargo = 24 x 91.125
Volume of the cargo = 2187 feet³
d)
The number of boxes = 12
The dimensions of the cargo be = 9 feet x 4.5 feet x 4.5 feet
So , the volume of the cargo = number of boxes x 9 x 4.5 x 4.5
On simplifying the equation , we get
Volume of the cargo = 12 x 182.25
Volume of the cargo = 2187 feet³
Hence , the volume of the rectangular cargo is 2187 feet³

What are the factors 60 that add up to 17? *
A company manufactures computers. Function N represents the number of components that a new employee can assemble per day. Function E represents the number of components that an experienced employee can assemble per day. In both functions, t represents the number of hours worked in one day.
N(t)=50t/t+4
E(t)= 70t/t+3
Which function describes the difference of the number of components assembled per day by the experienced and new employees?
A. D(t)= 10t(2t+13)/t+3
B. D(t)= 10t(2t+13)/ (t+4)(t+3)
C. D(t)= 10t(2t-13)/t+4
D. D(t)=10t(2t-13)/ (t+4)(t+3)
The difference of the number of components assembled per day by the experienced and new Employees is : D(t)= 10t(2t+13)/ (t+4)(t+3)
Here we perform subtraction :
D(t) = N(t) - E(t)
N(t) = 50t / (t+4)
E(t) = 70t / (t+3)
The difference :
D(t) = E(t) - N(t)
D(t) = [70t / (t+3)] - [50t / (t+4)]
The L.C.M of (t+3) and (t+4) is (t+3)(t+4)
[70t(t+4)] - [50t(t+3)] / (t+3)(t+4)
70t² + 280t - [50t² + 150t] / (t+3)(t+4)
[70t² + 280t - 50t² - 150t] / (t+3)(t+4)
20t² + 130t / (t+3)(t+4)
D(t) = 10t(2t + 13) / (t+3)(t+4)
The difference of the number of components assembled is : D(t)= 10t(2t+13)/ (t+4)(t+3)
