Answer:
b: The graphs will look the same
Step-by-step explanation:
a: The steps will be different, because if they use an x-y table to graph, calculating the numbers will different, because they put the negative sign in different parts of the fraction.
In reality, that won't make a difference.
The graphs will look the same regardless

Answer:
B) m + 7
Step-by-step explanation:
x + y + z = (m+9)/2 + (2m+15)/2 + (3m+18)/2 = (6m + 42)/2 = 3m + 21
Average of x, y, and z = (x + y + z)/3 = (3m + 21)/3 = m + 7
Answer:
m + 7
Step-by-step explanation:
\(x = \frac{m + 9}{2}\\ \\y = \frac{2m + 15}{2}\\\\z = \frac{3m + 18}{2}\\\\To\;\;find\;\;\\\frac{x+y+z}{3} \\\\= \frac{1}{3} *[\frac{m + 9}{2}+\frac{2m + 15}{2}+\frac{3m + 18}{2}]\\\\= \frac{6m + 42}{6}\\ \\= m + 7\)

Proportional relationships, please answer all of the parts! Thank you!
Answer:
a. No (see below)
b. (see below)
c. Johnny
d. Johnny = $12.50 / hour Doug = $9.16... / hour
e. Doug: extend the table to show how much he gets paid for 1 hour of work (the unit rate)
Johnny: already on the graph
Step-by-step explanation:
a. No. This is because a proportional relationship would have a certain ratio between payment and the amount of time spent working, which would not change. However, if Doug's neighbour pays him $55 for 6 hours, it's likely that this is not a proportional relationship, or we would be able to divide $55 by the 6 hours Doug spent working.
b. Even though above I said that it's probably not a proportional relationship, if it were, we would have to divide everything equally. I'm guessing the table should look like this:
Doug
Time (hr) Earnings ($)
4 $36.66...
5 $45.8333...
6 $55
7 $64.4666....
8 $73.333...
To work out how much Doug would get for working 4 hours:
4/6 x $55 = 2/3 x $55 = $36.66... (so definitely not a proportional relationship)
To work out how much Doug would get for working 5 hours:
5/6 x $55 = $45.8333.... (more evidence that this is not a proportional relationship)
To work out how much Doug would get for working 7 hours (we already got 6 hours):
7/6 x $55 = $64.4666...
To work out how much Doug would get for working 8 hours:
8/6 x $55 = $73.33... (we could double the 4 hour payment, but this is probably more accurate)
c. Johnny is getting paid more. If we look at how much Doug gets for 6 hours, it's $55. If we look out at how much Johnny gets for 6 hours, it's $75. (If we do the same with the other amounts of time, it's the same.
4 hours: D = $36.67 vs J = $50
5 hours: D = $45.83 VS J = $60
etc...
d. Johnny gets $75 per 6 hours --> 75/6 = $12.50 per hour
Doug gets $55 per 6 hours --> 55/6 = $9.1666... per hour
e. Carry on the table for Doug all the way to 1, so you can see the how much Doug gets paid for 1 hour of work (i.e. the minimum).
The unit rate is already on the graph for Johnny.

A group of 24 students spent 1,296 minutes studying for an upcoming test. What prediction can you make about the time it will take 150 students to study for the test?
It will take them 174 minutes.
It will take them 2,592 minutes.
It will take them 8,100 minutes.
It will take them 8,745 minutes.
Answer:
It will take them 8,100 minutes.
Step-by-step explanation:
If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)
150 x 54 minutes = 8,100 minutes.
It will take them 8,100 minutes.

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

An object has a mass of 17 grams.
What is its weight in ounces?
Use 1 ounce=28.35 gram to write the conversion facto
Step-by-step explanation:
In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:
17 grams * (1 ounce / 28.35 grams) = 0.6 ounces
Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.
Phil spent $17 of his $157 pocket money on eating out for one meal. What percent of Phil's pocket money did he spend on eating out for one meal?
Answer:
17/157=10.82%
Step-by-step explanation:
Answer: 10.8% (maybe 11% depending on if your teacher wants a decimal in the answer or not)
Step-by-step explanation:
157 x 0.108 = 16.956
16.956 can be rounded up to 17.
Therefore, Phil spent about 10.8% of his pocket money ($157).

Density is measured in units of mass per units of volume. It can be thought of as a unit rate. The mass of a block of aluminum is 9.45 grams. The volume is 3.5 cubic centimeters (cm³).
What is the density of aluminum?
Answer:
you answer will be 2.7
Step-by-step explanation:
you just have to divide the 9.45 to 3.5 and you got your answer
The density of the aluminum will be 2700 kilograms per cubic meter.
What is the density?The number of molecules per unit volume is known as density. The SI unit of the density is kilograms per meter cube. The density is a scalar quantity. More density means more the number of molecules present in a unit volume. Then the density is given as,
Density = Mass / Volume
A chunk of metal weighs 9.45 grams. 3.5 cubic centimeters is the volume.
Then the density of the aluminum is given as,
D = 9.45 / 3.5
D = 2.7 grams per cubic cm
D = 2700 kilograms per cubic meter
The density of the aluminum will be 2700 kilograms per cubic meter.

Step-by-step explanation:
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
