Which one of these relationships is different than the other three? Explain how you know. Hint: Find all
of the constants of proportionality.
Answer:
Graph 2 has a different constant of proportionality
Step-by-step explanation:
See attachment for graphs
To calculate the constant of proportionality, we simply determine the slope of each graph using
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where x's and y's are corresponding values of x and y
Graph 1:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (0.8,4)[/tex]
Substitute these values in: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{4 - 0}{0.8 - 0}[/tex]
[tex]m = \frac{4}{0.8}[/tex]
[tex]m = 5[/tex]
Graph 2:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (10,55)[/tex]
Substitute these values in: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{55 - 0}{10 - 0}[/tex]
[tex]m = \frac{55}{10}[/tex]
[tex]m = 5.5[/tex]
Graph 3:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (4,20)[/tex]
Substitute these values in: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{20 - 0}{4 - 0}[/tex]
[tex]m = \frac{20}{4}[/tex]
[tex]m = 5[/tex]
Graph 4:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (10,50)[/tex]
Substitute these values in: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{50 - 0}{10 - 0}[/tex]
[tex]m = \frac{50}{10}[/tex]
[tex]m = 5[/tex]
From the calculations above, graph 2 has a different constant of proportionality of 5.5 while others have 5 as their constant of proportionality

Step-by-step explanation:
Sohan was putting covers on his note books. He put 1/4th of the covers on monday. He put another 1/4th of the covers on tuesday and the remaining on wednesday. What fraction of covers did he put on wednesday?
Answer:
[tex]Wednesday = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]Monday = \frac{1}{4}[/tex]
[tex]Tuesday = \frac{1}{4}[/tex]
[tex]Wednesday = Others[/tex]
Required
Determine the fraction of Wednesday
The summation of fractions on each day must be equal to 1.
So:
[tex]Monday + Tuesday + Wednesday = 1[/tex]
Substitute values for Monday and Tuesday
[tex]\frac{1}{4} +\frac{1}{4} +Wednesday = 1[/tex]
Collect Like Terms
[tex]Wednesday = 1 - \frac{1}{4} -\frac{1}{4}[/tex]
Take LCM
[tex]Wednesday = \frac{4 - 1 - 1}{4}[/tex]
[tex]Wednesday = \frac{4 - 2}{4}[/tex]
[tex]Wednesday = \frac{2}{4}[/tex]
Simplify fraction
[tex]Wednesday = \frac{1}{2}[/tex]

a bakery uses flour at a rate of 1/3 pounds each minute. at approximately what rate does the bakery use flour, in pounds per day
Answer:
I'm pretty sure the bakery uses 480 pounds per day
Step-by-step explanation:
You would multiply 1/3 by 60, which is 60 minutes an hour, and that gives you 20 which you would then multiply 20 by 24, which is 24 hours a day, which would then give you 480 pounds of flour per day.
Answer:
480 pounds
Step-by-step explanation:
because 1/3 times 60 is 20 and that is 20 pound /a hour then multiply it by 24
because there are 24 hours a day

Please help! Question 7. BRAINLIEST TO CORRECT ANSWER!!!
A manufacturer determines that the number of toys it can sell is given by the formula
T=-4p2+160p-305, where p is the price of the toys in dollars.
At what price will the manufacturer sell the maximum number of toys and what is the maximum
number of toys that can be sold?
Answer:
The price where the manufacture sells the maximum number of toys is $20
Step-by-step explanation:
The given equation for that represents the number of toys the manufacturer can sell is given as follows;
T = -4·p² + 160·p - 305
Where;
p = The price of the toys in dollars
At the point where the manufacture sells the maxim number of toys on the graph of the equation T = -4·p² + 160·p - 305, which is the top of the graph, the slope = 0
Therefore, at the maximum point;
The slope = 0 = dT/dp = d(-4·p² + 160·p - 305)/dp = -8·p + 160
∴ -8·p + 160 = 0
160 = 8·p
8·p = 160
p = 160/8 = 20
The price where the manufacture sells the maximum number of toys is = p = 20 dollars

Write a number that is a rational number, but not an integer.
Answer:
1.6
this is a rational number, since it can be written in fraction form, however it is not an integer because it is a decimal number and not a whole number.
====================================================
Explanation:
Pick any two numbers you want as long as they don't divide to form an integer. For instance, picking 14 and 7 divides to 14/7 = 2 which is an integer. So this pair of values won't work.
In this case, 2 and 3 don't divide to form an integer. We can see this through using a calculator
2/3 = 0.667 approximately
Note: The denominator can never be zero. The numerator can be zero, but a zero numerator leads to an integer, so you'll have to ignore zero entirely for this problem.

Step-by-step explanation:
Which division problem does the model show? 3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third. 3 divided by one-third = 9 3 divided by two-thirds = 9 9 divided by one-third = 3 9 divided by two-thirds = 3
Step-by-step explanation:
There are three big '1' blocks shaded in dark blue. They have a total sum of 3.
There are 9 small '1/3' blocks shaded in light blue. They also have a total sum of 3.
We can divide the total sum, 3, by the '1/3' blocks to get 9 blocks.
The division problem being shown is 3 / (1/3) = 9.
The division 3 ÷ (1/3) model shows 3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third option first is correct.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
As we can see in the picture:
There is a dark blue box in which there are 3 times 1 so the total sum of the ones:
= 1
There are three sky blue boxes each box contains 1/3 of the sum of the all 1/3 is:
=9(1/3)
= 3
So the fraction becomes:
[tex]= \frac{3}{\frac{1}{3} }[/tex] or
= 3 ÷ (1/3)
= 9
Thus, the division 3 ÷ (1/3) model shows 3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third option first is correct.

1. Find the value of x.
55°
(4x - 5)°
O
26
O
Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26
