Yes, the conveyors are in a proportional relationship.
Given,
A conveyor belt moves at a constant rate of 12 feet in 3 seconds.
A second conveyor belt moves 16 feet in 4 seconds.
We need to find whether the two conveyors are in proportion relationship.
What is a proportional relationship?
There is a proportional relationship if the ratios of each pair of values are the same.
We have,
- First conveyor belt
12 feet in 3 seconds.
Ratio = 12 / 3 = 4
- Second conveyor belt
16 feet in 4 seconds.
Ratio = 16 / 4 = 4
Ratios are the same.
4 = 4
Thus the conveyors are in a proportional relationship.

Point T is on line segment \overline{SU} SU . Given SU=4x+1,SU=4x+1, TU=3x,TU=3x, and ST=3x-1,ST=3x−1, determine the numerical length of \overline{SU}. SU
Answer:
The numerical length of SU =
5 units
Step-by-step explanation:
Here, we want to get the length of point SU
mathematically;
SU = ST + TU
4x + 1 = 3x -1 + 3x
4x + 1 = 6x - 1
6x-4x = 1 + 1
2x = 2
x =2/2 = 1
But SU = 4x + 1 = 4(1) + 1 = 5 units

Six years after a tree was planted, its height was 7 feet. Nine years after it was planted, its height was 16
feet. Which of the following equations gives the heighty, in feet, of the tree after x years if the tree grows at
a constant rate? Check all of the boxes that apply.
y - 6 =3(x - 10)
y-16 = 3(x-9)
y = 3x - 11
y=-3x - 23
I'm not good in this but.....
x = years
9x-6x = 16-7
3x = 9
x = 3
That means the tree will grow three feet per year.
A property insurance policy is issued at a total cost of $2,540 for 6 months. If the insurance company offers a one-time $50 rebate, what is the cost per month?
Answer:
$431.67
Step-by-step explanation:
Let
The one time $50 rebate be for the first month
Cost of insurance per month = x
First month cost of insurance = x-50
Total cost of insurance = $2,540
Total cost of insurance = 1st + 2nd + 3rd + 4th + 5th + 6th
2,540 = x-50 + x + x + x + x + x
2540 + 50 = 6x
2590 = 6x
Divide both sides by 6
x= 2,590 / 6
= 431.67
x= $431,67
The cost of the insurance per month = $431.67
Check:
$431.67 * 6 months
=$2,590.02
Minus one time rebate of $50
= $2,590.02 - $50
= $2,540.02
Approximately
$2,540

The tables show linear functions representing the cost per hour to rent a bicycle and the cost per hour to rent in-line skates. Bicycle per Hour In-Line Skates per Hour Which function has the greater slope and what does it represent? The in-line skate function has the greater slope, which shows that the cost per hour is greater than that of the bicycles The in-line skate function has the greater slope, which shows that the cost per hour is less than that of the bicycles. The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates. The bicycle function has the greater slope, which shows that the cost per hour is less than that of the in-line skates.
Answer:the bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates
Step-by-step explanation:
The function has the greater slope and it represent : The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates
What are linear functions?
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
What is slope?The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
According to the question
The cost per hour to rent a bicycle and the cost per hour to rent in-line skates are given .
We will conclude which function has the greater slopes
if any function have greater slope than other that implies that it have greater change in y axis in comparison to other
as over here
y axis = cost
x axis = hours
Therefore,
The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates
Hence, The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

What is the mean of the data set (3, 2, 2, 12, 6, 5, 14, 4]? O 2 O 4 O 6 O 7
Answer: 6
Step-by-step explanation:
{3, 2, 2, 12, 6, 5, 14, 4}
To find the mean,add everything up, the divide it by how many numbers you added up.
So, do :
3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48
Then, because you added 8 numbers together, you would divide 8 from 48.
48 ÷ 8 = 6
So, your mean is 6

wallpaper is sold in rolls that are 2 feet wide what is the minimum length you would need to purchase to cover the wall and 60 feet covers the wall
Answer:
28feetStep-by-step explanation:
Let the wallpaper be a rectangle
Area of a rectangle = Length * Width
A = LW
Perimeter P = 2L+2W
If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.
60 = 2L + 2(2)
60 = 2L + 4
2L = 60-4
2L = 56
L = 56/2
L = 28
The minimum length that will be purchased to cover the wall is 28 feet

how to expand a using the distributive law
Answer:
2x(3x+5)+1(3x+5)
Step-by-step explanation:
The distributive law is the law that states that multiplying a number by a group of numbers is the same as doing each multiplication separately. Eg. A(B+C) =AB+AC
In the case of two sets of parenthesis it would look like:
2x(3x+5)+1(3x+5)
Which would give us:
6x^2 +10x +3x+5
6x^2+13x+5
The general format for 2 bracket ones would be:
(A+B) (C+D) =A(C+D) +B(C+D)
where the two terms in the first bracket go outside the second bracket twice individually because each term must be multiplied by all terms in the other bracket.
