Which graph of ordered pairs shows a proportional relationship?
(Provide an explanation if you can! Thanks.)
Answer:
1 and 4 i think they look proportional
Answer:
Only the first graph
Step-by-step explanation:
In order for a equation to be proportional it has to have a straight line (which indicates that it has a constant rate of change.) and it has to go through the origin
If you were to draw a line straight through the ordered pairs of graph 1 it would be a straight line and it would go through the origin (0,0)
therefore graph one would show a proportional relationship
What type of angle pair is it?

Step-by-step explanation:
Chelsea mailed 2 boxes and 2 bags to her uncle in army. The two boxes weighed 8 ½ pounds each and the two bags weighed 4 ½ pounds each. How many pounds do all 2 boxes and 2 bags weigh?
Answer:26
Step-by-step explanation:
4.5x2=9+17=26
8.5x2=17
Answer:
26lbs.
Step-by-step explanation:
this problem is quite simple when we break it down
first we multiply each of the amounts of the bags and the boxes by two to represent the two of each items as shown
8 1/2 * 2 = 17
4 1/2 * 2 = 9
then all we have to do is add the two new amounts together and TADA:
17 + 9 = 26
we have our answer
NOTE: when multiplying a fraction, you are multiplying how many parts (the numerator) and NOT the size of the part within the whole number (the denominator) in this case 1/2 * 2 = 2/2 and 2/2 = 1

There are 16 dogs at the dog park last Saturday, and 6 of them were poodles. Considering this data, how many of the next 10 dogs to arrive at the park next Saturday should you expect to be poodles?
Answer:
3 poodles.
Step-by-step explanation:
6/16 dogs were poodles, so 3/8 of the total number.
If now we consider 10 dogs, we have to calculate 3/8 of them-
Which is 3,75 and it makes no sense because it has decimals, so the actual number of poodles is 3

Step-by-step explanation:
What is the length of the base of a parallelogram if the Area is 125 sq. yds., and the height is 5 yds. ? Just put the answer. Hint: write the formula for area of a parallelogram and substitute what information you know. Use algebra to solve.
Answer:
25 yd = L
Step-by-step explanation:
The formula for the area of a parallelogram of length L and width W is
A = L * W.
Here we know that A = 125 yd^2, which (from the formula) equals (L)(5 yd).
125 yd^2
Solving for the length, L, we get L = --------------- = 25 yd = L
5 yd

Answer:
A. Each large envelope costs $1.42
Step-by-step explanation:
To solve this, we want to set up a system of equations.
The first customer paid $12 for 14 postcards & 5 large envelopes.
The total number of dollars paid is $12. This will be on one side of the equal sign.They bought 14 postcards. This will be represented by 14p.They bought 5 large envelopes. This will be represented by 5eThe equation will be: 14p + 5e = 12The second customer paid $24.80 for 10 postcards & 15 large envelopes.
The total number of dollars paid is $24.80. This will be on one side of the equal sign.They bought 10 postcards. This will be represented by 10p.They bought 15 large envelopes. This will be represented by 15eThe equation will be: 10p + 15e = 24.80Now let's set up our equations together.
14p + 5e = 12
10p + 15e = 24.80
We will solve this through elimination. First we want to eliminate one variable at a time. We will start with e because we can see that 5 and 15 will simplify easily.
Multiply the first equation by -3 to cancel out the variable e.
-3(14p + 5e = 12) = -42p - 15e = -36
Now set this up for elimination.
-42p - 15e = -36
10p + 15e = 24.80
______________
-32p = -11.2
Divide both sides by -32.
p = 0.35
Each postcard costs $0.35.
Now that we know the value of p, let's plug it into one of equations to find e.
14p + 5e = 12
14(0.35) + 5e = 12
4.9 + 5e = 12
5e = 7.1
e = 1.42
Each large envelope costs $1.42
Check your answer by plugging both values back into the equation you haven't used yet.
10p + 15e = 24.80
10(0.35) + 15(1.42) = 24.80
3.5 + 21.3 = 24.80
24.80 = 24.80
Your answer is correct.
Hope this helps!
Solve the problem in the example. Show your work.
You would have to divide 195 by both 15 and 12 to get both hours mowing and hours babysitting.
195 / 15 = 13
195 / 12 = 16 1/4
now if you put the answers in place of b and m you would get (15*13) + (12*16.25) = 195
Answer: 195
Conclusion: Sophia gets over payed
Step-by-step explanation:
One hour of babysitting costs $15 One hour of mowing costs $12
Let the of hours babysitting be x, Let the hours of mowing be y,
$195÷2=$97.5
$195-$49.5 = $145.5 $97.5 - 12 X 4 =$49.5
∴ Total money Sophia got for ∴ Total money Sophia got
baby sitting is $145.5. mowing is $49.5.
Now, Now,
15 X x = $145.5 $12 X y = $49.5
x = [tex]\frac{145.5}{15}[/tex] y = [tex]\frac{49.5}{12}[/tex]
x = 9.7 y = 4.125
∴ Sophie babysitted for ∴ Sophia mowed for 4.125 hours.
9.7 hours.
Note:
You can check if your answer is correct like this:
Multiply 9.7 by $15 ( you will get $145.5 as the answer)
Then, multiply 4.125 by $12 (you will get $49.5 as the answer)
Lastly, add the answers together.($145.5 + $49.5 which will give the answer
as $195)
And boom you got the same answer as written in the question.
It's just a small trick to check if your answer is correct.
I hope this will help you!!!
