Answer:
proportional relationship does not exist.
proportional relationship does exist.
proportional relationship does not exist.
proportional relationship does exist.
Step-by-step explanation:
To establish proportionality :
For data 1:
y α x
y = kx ; k = proportionality constant
Take x = 1 ; y = 5
5 = k
k = 5
Hence, to obtain other data points :
y = 5x (if data is proportional ; if otherwise, the data isn't proportional).
Take ; x = 2
y = 5* 2 = 10
10 ≠ 9
Hence, data isn't proportional.
2.)
Data 2:
y α x
y = kx ; k = proportionality constant
Take x = hours 2 ; y = miles = 110
110 = 2k
k = 110/2
k = 55
Take ; x = 5
y = 55*5 = 275
275 = 275 (proportional relationship exist)
3.)
For the graph:
First graph isn't proportional
4 = 2k ; k = 4/2 = 2 ; k = 2
At x = 6
y = 6*2 = 12
From graph ; y = 8 at x = 6
Hence, proportional relationship does not exist.
4.)
For the 2nd graph:
4 = 2k ; k = 4/2 = 2 ; k = 2
At x = 6
y = 6*2 = 12
From graph ; y = 12 at x = 6
Hence, proportional relationship does exist.

Step-by-step explanation:
if you try out 710 divided by 7 times 3 it doesn't equal 390 dollars, so you're not getting a fair price and you're paying extra, whereas you know on the first one that if you double 360 by 2 it equals 720 so it is a linear pricing
Jayden and Derek go to Chipotle. Jayden gets a burrito for $7.49 and Derek gets a lifestyle bowl for $8.29. They each get a drink for $1.79. If they have to pay 8% tax on their meal, what will the total cost be?
Answer:
$18.97
Step-by-step explanation:
Add $7.49, $8.29, and $1.79 together= $17.57.
Then, add the 8% tax. So $17.57+8% of tax= $18.97.

A division problem is shown below.
Long division showing 368 divided by 23. First step 368 minus 230 equals 138. Second step is 138 minus 138 equals 0.
Enter numbers in the boxes below to show how to use partial products to divide.
Step 1:
group(s) what of 23 = 230.
Step 2:
group(s) what of 23 = 138.
Step 3: Add the partial quotients:
what + what = what
Answer:
16
Step-by-step explanation:
a, 10
Group of 10 23s gives us 230. This is so because of you arrange 23 in groups, you would need to arrange it in 10 places, to get 230.
b, 6
Group of 6 23s gives 138. Again, like stated above, arranging 23 in 6 places ends up giving us a total of 138.
Adding both together, we have
10 + 6 = 16.
This means our answer is 16. And this is rightly so. Dividing 368 by 23 gives us 16 exactly. So, 16 is the answer.

Answer:
the 1st one. the unit rate is $21.00
А
is 35% of
B.
then
B
А
is 65:35.
Find 35% of 65, since A= 35 and B= 65.
35%=.35
Multiply that by 65, for the percentage.
65*.35= 22.75
So, 35% of 65= 22.75
22.75 is not equal to 35.
This statement is false.

Answer:
it states to round to the tenths place for 1 which would be 1.5 because the 2 after is not 5 or above so it stays the same

My answers:
2)76.27
3)23.494
4)8.3926
5)342.6
Answer:
You can easily round any number to any place using a simple rule. Look to the digit to the right of the digit you want to round to. If that digit is 5 or greater than 5, you round UP to the next higher digit. If the digit to the right of the digit you’re trying to round to is 4 or less, you leave the digit alone.
1. 1.528 = 1.5
2. 76.2714 = 76.27
3. 23.49382 = 23.494
4. 8.39261 = 8.926
5. 342.62984 = 342.6
The probability of rolling a 6 with a six-sided number cube is 1/6 Choose the
likelihood that best describes the probability of this event.
Answer:
UNLIKELY
Step-by-step explanation:
Given that:
Probability of rolling a six with a six sided nuner cube = 1/6
Required outcome / Total possible outcomes
Number of 6 / total sides of number cube = 1/6
The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.
Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'

Step-by-step explanation:
At a book sale, all paperback books cost d dollars each and all hard books cost 2d dollars each. If Kate paid 7d dollars for 5 books at this sale, how many paperback books did she buy?
Answer:
3 paperback books
Step-by-step explanation:
Let the number of paperback Kate bought be a and the number of hard books be b.
Given that she bought 5 books then
a + b = 5
Also, If Kate paid 7d dollars then
a * d + b * 2d = 7d
Divide through by d
a + 2b = 7
Hence we have 2 equations
a + b = 5
a + 2b = 7
subtract the first from the second
2b - b = 7 - 5
b = 2
since
a + b = 5
a + 2 = 5
a = 5 - 2
= 3
Recall that the number of paperback she bought is a hence this is 3

Answer:
1,680
Step-by-step explanation:
We know a hummingbird beats its wings 420 times in 30 seconds. To find the unit rate, divide 420 by 30.
420/30
42/3
14 beats/second
Now we know a hummingbird beats its wings 14 times in 1 second. Two minutes equals 120 seconds. Multiply 14 by 120 to get the answer here.
14 * 120
(14 * 12) * 10
168 * 10
1,680 beats
Answer:
1680
Step-by-step explanation:
From the table, we can see that per each 30 seconds, a mocking bird flaps its wings 420 times.
Each minute contains 60 seconds. Therefore, in order to calculate the number of times a mockingbird flaps its wings in 2 minutes, we can
60 seconds x 2 minutes = 120
Then, we can divide this number by 30 to figure out how many times we need to multiply 420 to get our answer.
120/30 = 4
Therefore,
420 x 4 = 1680
Sue is drawing two lines on a coordinate plane. She begins the first line at the origin and ends at (4,3). She begins the 2nd line at (0,4) and ends at (3,0). Where will these lines intersect?
PLEASE HELP
The point of intersection of the lines, if The coordinates of the first line (0, 0) and (4, 3), and The coordinates of the second line (0, 4) and (3, 0), is (1.92, 1.44).
What is a line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Given:
The coordinates of the first line (0, 0) and (4, 3),
The coordinates of the second line (0, 4) and (3, 0),
Write the equation of the line as shown below,
The equation of the first line,
y - 0 = 3 - 0 / 4 - 0 (x - 0)
y = 3/4 x
4y = 3x
4y - 3x = 0
The equation of the second line,
y - 0 = (0 - 4) / (3 - 0) (x - 3)
y = -4 / 3 (x - 3)
3y = -4x + 12
3y + 4x = 12
Solve these equations,
x = 1.92 and y = 1.44
Thus, they intersect at (1.92, 1.44)
