The table below would represent a proportional relationship except for one y-value. Identify which y-value prevents the table from representing a proportional relationship. Then, select the value that would make the table proportional.
X 1.5, 2, 4, 4.5, 7
Y 6, 8, 16, 16.5, 28
Alternative values 17, 18, 18.5, 19.5, 20
9514 1404 393
Answer:
non-proportional y-value: 16.5
corresponding proportional y-value: 18
Step-by-step explanation:
Each y-value is 4 times the corresponding x-value except for (x, y) = (4.5, 16.5).
The correct proportional values would be (4.5, 18).
Yes, because each input has an output.
Yes, because 3 has one output.
No, because 1 has two inputs.
No, because -2 has two outputs.
Answer:
no because -2 has two outputs

The sales tax rate in New Mexico is 5.125%. What will you pay for a $14.50 area rug in New Mexico after tax?
Answer:
15.243125
Step-by-step explanation:
we need to calculate how much would be the tax for 14.5$
so 14.5 * 5.125% = 0.743125
and then we will add that to 14.50

If ‘c’ is directly proportional to‘d’ and c = 24 when d = 4
Find an equation connecting ‘c’ and ‘d’
Find ‘c’ when d = 8
Find ‘d’ when c = 54
Answer:
When d = 8
c = 48
when c = 54
d = 9
Step-by-step explanation:
We have the equation c is proportional to d
[tex]c \: \: \: \alpha \: \: d[/tex]
ie
[tex]\frac{c}{d} = \: a \: constant[/tex]
here given that c = 24 and d = 4 so,
[tex] \frac{c}{d} = \frac{24}{4} = 6[/tex]
so we have to find values for c and d which gives
c/d = 6
so when d = 8
[tex] \frac{c}{8} = 6 \\ so \: \\ c = 8 \times 6 = 48 \\ \\ and \: when \: \\ c \: = 54 \\ \\ \frac{54}{d } = 6 \\ \\ d \: = \frac{54}{6} = 9[/tex]
Answer:
c = 6dc = 48 when d=8d = 9 when c=54Step-by-step explanation:
We know:
‘c’ is directly proportional to‘d’
and
c = 24 when d = 4
W can write this in mathematical form as:
c∝d
Removing the proportionality symbol, k is the constant of proportionality
c = kd
To find the value of k, putting the known values of c and d
[tex]24 = k * 4\\k = \frac{24}{4} = 6[/tex]
So the equation becomes
[tex]c = 6d[/tex]
To find the value of c when d = 8
[tex]c = 6*8\\c = 48[/tex]
To find the value of d when c=54
[tex]54 = 6d\\d = \frac{54}{6}\\d = 9[/tex]
Hence,
c = 6dc = 48 when d=8d = 9 when c=54Solve for X

Answer:
So 180-94 =86 so then it becomes 60°, 86°, and 2x so you would then add 60 and 86 together and get 146 and 180 - 146 is 34 then divide by two and you get 17 so x=17°
Step-by-step explanation:
Sorry if that’s confusing
Answer:
x = 17
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
94° is an exterior angle of the triangle, thus
2x + 60 = 94 ( subtract 60 from both sides )
2x = 34 ( divide both sides by 2 )
x = 17
write 15% as a fraction step by step
Answer:
15/100
Step-by-step explanation:
15% is out of 100% so when writing it into a fraction it is 15 over 100, because 15% is out of 100%
Hint:If you want to put it into a decimal it will be 0.15 so when turning it into a fraction, the 1 is in the tenths place and the 5 is in the hundredths place.

An unbiased dice with faces marked 1, 2, 3, 4, 5 and 6 is rolled four times. Out of four face values obtained, the probability that the minimum value is not less than 2 and the maximum value is not
greater than 5 is:
a) 1/81 b) 80/81
c) 16/81 d) 65/81
Solution with some explanation
Step-by-step explanation:
Let us intepret this condition in our context:
"...that the minimum value is not less than 2 and the maximum value is not greater than 5"
This means that when we roll the dice, we do not want 1 or 6 to appear. Instead we wish for 2/3/4/5 to appear.
The probability of getting these four sides out of six in a roll is 4/6, or 2/3.
We have to roll this dice 4 times. Hence we raise the probability to a power of 4:
Total probability = (2/3)⁴
= (2)⁴ / (3)⁴
= 16/81. (C)

A rabbit moves n times as fast as a squirrel . A fox moves m times as fast as a rabbit . The fox moves how many times as fast as the squirrel?
Answer:
the fox moves mn times as fast as the squirrel
Step-by-step explanation:
the easiest way to do problems like this is by using hypothetical values that make sense (it's best to avoid 0, 1, and 2)
we'll say that n = 3 and m = 4
so if the squirrel moves at s pace, then the rabbit moves at ns, or 3s.
if the fox moves at m (4) times the rabbit's pace (3s), then it moves at 4(3s)
then just switch out the numbers for their variables, giving you m(ns)
remember that s simply represents the squirrel's pace, we cannot replace it with a number in this case, so switch it with the idea/value it represents
and there you go, mn times the squirrel's pace

How can you use addition rules to solve subtraction problems with integers?
Answer:
Not entirely sure about what the question is asking, but explanation of what I think it is asking.
Step-by-step explanation:
There are three basic rules of addition.
Positive + Positive = Positive Ex: 1+1=2
Negative + Negative = Negative Ex: -2+-2=-4
Negative + Positive = Positive or Negative depending on the value.
Ex= 1+(-2)=(-1)
Ex=2+(-1)=1
So subtraction problems can be turned into addition problems.
For example:
4-2 is the same as 4+(-2).
Or -5-7 is the same as -5+(-7).
Hope this makes sense.

A function is shown. To the nearest whole number, what is the average rate of change of the function over the interval from x = 0 to x = 15? f(x) = 50,900(1.03)
Answer:
X=13
Step-by-step explanation:
Answer:
1893 or B
Step-by-step explanation:
To find the rate of change we divide the output value by the input values in this case
f(x) = 50,900(1.03)^0= 50900
f(x) = 50,900(1.03)^15= 79300
79300-50900=28400
So if we find the Rate of change by dividing the output value by the input value so we have 28400/15=1893 that is how you get your answer
Manny makes dinner using 1 box of pasta and 1 jar of sauce. If pasta is sold in packages of 10 boxes and sauce is sold in packages of 2 jars, what is the least number of dinners that Manny can make without any supplies leftover?
Answer:
10 dinners
Step-by-step explanation:
We solve using the Least Common Multiple Method.
We are told:
Pasta is sold in packages of 10 boxes Sauce is sold in packages of 2 jars.
We find the Multiples of 2 and 10
Multiples of 2:
2, 4, 6, 8, 10, 12, 14
Multiples of 10:
10, 20, 30
Therefore,
LCM(2, 10) = 10
The least number of dinners that Manny can make without any supplies leftover is 10 dinners
