The relationship between the length of a side and the area is non proportional.

The answer is non proportional because the side length is x,

so is the other side lengths.

The side lengths are all equal and to find area you do x squared or x times x.

So they are not proportional because there will be different numbers for each.

For example. X= 2, area ( x squared ) is 4.

Hence, The relationship between the length of a side and the area is non proportional.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

In a square, we need to find the relationship between the length of a side and the area.

Answer:

[tex]\frac{5}{6} * 15 = 12\frac{1}{2}[/tex]

[tex]\frac{2}{3} * \frac{1}{4} = \frac{1}{6}[/tex]

[tex]\frac{4}{9} * \frac{3}{8} = \frac{1}{6}[/tex]

Step-by-step explanation:

[tex]\frac{5}{6} * 15 = \frac{5 * 15}{6} = \frac{75}{6}\\[/tex]

Reduce the fraction by diving both sides by the common factor.

[tex]\frac{75}{6} = \frac{75 / 3}{6/3} = \frac{25}{2}[/tex]

To convert the improper fraction to a mixed fraction, divide the numerator (25) by the denominator (2), put the whole part of the result in front and the remainder in place of the original numerator.

25 / 2 = 12 with remainder of 1

[tex]\frac{25}{2} = 12\frac{1}{2}[/tex]

[tex]\frac{2}{3} * \frac{1}{4} = \frac{2 * 1}{3 * 4} = \frac{2}{12} = \frac{2/2}{12/2} = \frac{1}{6}[/tex]

[tex]\frac{4}{9} * \frac{3}{8} = \frac{4 * 3}{9 * 8} = \frac{12}{72} = \frac{12 / 12}{72 / 12} = \frac{1}{6}[/tex]

Answer:

7 : 1.

Step-by-step explanation:

1 - 7/8 = 1/8 is syrup.

So, water to syrup

= 7/8 : 1/8

= 7 :1.

The ratio of water to syrup is 7:1

The quantitative relation between two amounts showing the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"

Given here, 7/8 of a can of drink is water, the rest is syrup thus the fraction for syrup is 1/8 of the can. Therefore the ratio of water and syrup is

7/8:1/8=7:1

Hence, The ratio of water to syrup is 7:1

Step-by-step explanation:

and got it right on edmentum

We get that the solution for the equation 4 x² - 7 x = 3 x + 24 as 4 or 3 / 2.

We are given an equation:

4 x² - 7 x = 3 x + 24

We need to solve it for x.

4 x² - 7 x - 3 x = 24

4 x ² - 10 x = 24

4 x ² - 10 x - 24 = 0

4 x² - 16 x + 6 x - 24 = 0

4 x( x - 4) + 6( x - 4) = 0

(x - 4)(4 x + 6) = 0

Solving for x, we get that:

x = 4 or x = 6 / 4 = 3 / 2.

Therefore, we get that the solution for the equation 4 x² - 7 x = 3 x + 24 as 4 or 3 / 2.

Average speed of the train as it covered 30 kilometers in 8 minutes is equal to 139.8 miles per hour.

As given,

Total distance= 30 kilometers

Total time taken = 8 minutes

1 kilometer = 0.62137 miles

30 kilometers = 30 × 0.62137

                     = 18.641 miles

8 minutes = ( 8 / 60) hour

Average speed= total distance / total time taken

                                          = 18.641 / (8/60)

                                          = 139.8 miles/ hour

Slope of line PQ = -3

Slope of line RS = 3

They are neither parallel nor perpendicular.

If two lines are parallel to each other, they would have the same slope value.

If two line are perpendicular, the slope value of one would be the negative reciprocal of the other.

Slope = change in y / change in x.

Slope of line PQ = (-1 - 14) / (2 - (-3))

Slope of line PQ = -15/5 = -3

Slope of line PQ = -3

Slope of line RS = (-10 - 8) / (-2 - 4)

Slope of line RS = -18/-6

Slope of line RS = 3

Answer:

128.52

Step-by-step explanation:

140 × (1-0.15) = 119

119 × 1.08 = 128.52

Answer:

$128.52

Step-by-step explanation:

Firstly to find the price of the scooter, you divide 140 by 100 and then multiply it by 15. The answer is what you subtract from the original price.

15(140/100) = 21

140 - 21 = 119

Now that we have the price of the scooter after the discount, we need to figure out the price of the sales tax. Sales tax is based on the reduced price, so we need to take the same steps as before to find the price. Divide 119 by 100, then multiply it by 8, then add the total to 119.

8(119/100) = 9.52

119 + 9.52 = 128.52

Answer = $128.52

Salma can rent the car for at most 5 days while driving 275 miles

Although part of your question is missing, you might be referring to this full question: A rental car company charges $22.50 per day to rent a car and $0.10 for every mile driven. Salma wants to rent a car, knowing that: she plans to drive 275 miles. She has at most $140 to spend. Write and solve an inequality which can be used to determine, the number of days Salma can afford to rent the car while staying within her budget

The equation which addresses this problem is:

22.5x + 0.10(275) <=140

Let x be the number of days Salma can afford to rent the car

Per day rent of the car = $22.5

Cost per mile = $0.10

Plan to drive = 275 miles

Budget with Salma = $140

Equation:

22.5x + 0.10(275) <= 140

Solving the equation we get x <= 5

So, Salma can rent the car for at most 5 days while driving 275 miles

Given three relations between the costs of balls, bats, and bases, you want to find the cost of each.

Solving three linear equations in three unknowns can be accomplished easily by any number of calculators, apps, or spreadsheets. Here, we'll use an ad hoc solution.

Subtracting twice the third equation from the second, we have ...

  (4 balls + 8 bats + 2 bases) -(2(2 balls + 3 bats + 1 base) = 78 -2(33.60)

  2 bats = 10.80 . . . . . . . simplify

  1 bat = 5.40 . . . . . . divide by 2

Subtracting the second equation from the first, we have ...

  (10 balls +3 bats +2 bases) -(4 balls +8 bats +2 bases) = (99) -(78)

  6 balls -5 bats = 21 . . . . . simplify

  6 balls = 21 + 5(5.40) . . . . . add 5 bats and substitute their cost

  6 balls = 48 . . . . . . . . simplify

  1 ball = 8.00 . . . . . . . divide by 6

Using the last equation, we can find the cost of 1 base.

  1 base = 33.60 -2 balls -3 bats = 33.60 -2(8.00) -3(5.40)

  1 base = 1.40

The costs are ...

  1 ball: $8.00

  1 bat: $5.40

  1 base: $1.40
