The percent of increase for a population that changed from 25,000 to 30,000 will be 20%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The population changed from 25,000 to 30,000. Then the percentage is calculated as,

P = [(30,000 - 25,000) / 25,000] x 100

P = (5,000 / 25,000) x 100

P = 0.20 x 100

P = 20%

The percent of increase for a population that changed from 25,000 to 30,000 will be 20%.

Answer: Kim is 16 and Alan is 20

Kim => x

Alan => y

Kim is 4/5 as old as Alan  =>  [tex]x=\frac{4}{5}y[/tex]

In four years, she will be 5/6 as old as he will be => [tex]x+4=\frac{5}{6}(y+4)[/tex]

Solving the system we obtain x=16 and y=20

Answer:

-4

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1)

Where m is the slope and (x1,y1) is a point on the line

y + 3 = -4(x - 5)

The slope is -4

The lines in the picture parallel because they are equal width apart , option (D) is correct.

Two straight lines in a plane such that even on getting extend till infinity they do not intersect each other and always at same distance from each other .

In the given picture the red line and black lines appears to have same distance between them .They are parallel not only because they are coplanar as coplanar lines can intersect each other.

Two lines travelling to infinity need not to be parallel always as they can intersect at some point and still travel to infinity.

If two lines of same size are there still they can have different perpendicular distance between them at diff points, they can be slightly tilted towards each other . Therefore they need not be parallel when they are of same size. And given lines are infinite therefore we cannot say that they are of same size also.

If two lines are equal width apart and never meet then it means the distance between them is always same therefore they are parallel,

Therefore, the lines in the  picture are parallel because they are equal width apart option (d) is correct.

Answer: it’s C.

Step-by-step explanation:

The equation that represents the new price of a bag is y = 1.28p.

Markup rate is the ratio of the difference between the selling price and cost price to the cost price. It is given by:

Markup rate = (selling price - cost price)/cost price

Given that y is the selling price, p is the cost price and the markup rate is 28%, hence:

28% = (y- p)/p

y-p = 0.28p

y = 1.28p

Hence the equation that represents the new price of a bag is y = 1.28p.

Answer:

x = 41

y = 24

Step-by-step explanation:

Systems of equations is,

-2x - 7y = -250 ------(1)

4x - y = 140 ------(2)

Equation (1) multiplied by 2 then added to equation (2)

  -4x -14y = -500

(+)   4x - y = 140  

          -15y = -360

             y = [tex]\frac{360}{15}[/tex]

            y = 24

by putting y = 24 in equation (2),

4x - 24 = 140

4x = 140 + 24

x = [tex]\frac{164}{4}[/tex]

x = 41

For x = 41 and y = 24 both the equations are true.

Equation (1),   -2(41) - 7(24) = -250  [True]

Equation (2),   4(41) - (24) = 140  [True]

The equation is 100 + 30m = 50m and the no. of months for which total cost of both the gyms will be same is 5 months.

A linear equation is an algebraic equation in which a variable has a highest degree of 1.

According to the given question At Work-It-Out, a gym membership is $50 per month with no registration fee and At Get Fit, the registration fee is $100 and membership costs $30 per month.

Given no. of months is m.

∴ 50m = 30m + 100

50m - 30m = 100.

Step-by-step explanation:

The slope-intercept form of a line is y = mx + b where m and b are the slope and y-intercept respectively. From the graph we see that b = 11 (because it is halfway between 10 and 12) and m = 3 (see 2 marked points on the graph). Therefore our answer is y = 3x + 11.
