Answer:

people 2010:

224,000

people in 2015:

224,000(1+0.06) =237,440

people in 2020

237440(1-0.04) =227,942

The population increased between 2010 and 2015, with 4000 being the nearest 100 persons.

percentage, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

Given, In 2010, the population of the city was 224,000. From 2010 to 2015, the population grew by 6%. hence,

Population by 2015 = 224,000 * (1.06) = 2,37,440

Also given, From 2015 to 2020, it fell by 4%. Hence,

Population by 2020 = 237,440 * 0.96 = 227942

Thus, the population difference between 2010 and 2020 = 227942 - 224,000

the population difference between 2010 and 2020 = 3942

Therefore, the population growth from 2010 to 2015, to the nearest 100 people is 4000.

Answer:

The correct choices are: Both tables are relations because both display a set of ordered pairs, and table B is a function because each input has exactly one output.

Step-by-step explanation:

Both statements are true, both tables can be considered relations since all functions are relations, and because table A has proper inputs and outputs despite the fact of the same inputs resulting in different outputs. Table B can be considered a function because it has different inputs that each have an output, and there is no same input value that results in different outputs.

Answer:

x=136 degrees

Step-by-step explanation:

ok so basically the angles are the same because the line intersects both lines at the same degree.

Answer:

136°

Step-by-step explanation:

Since both line are equal in length and size and both straight then if on side is 136° then the other side must be 136°

Answer:

9). 15 miles

10). 12880.8 in²

Step-by-step explanation:

9). Total distance to be covered by Kelly = Perimeter of the given triangle

                                                                    = Sum of three sides of the triangle

    To know the length of Laurel drive (Hypotenuse of the triangle), we will apply Pythagoras theorem in the given triangle,

    (Hypotenuse)² = (Leg 1)² + (Leg 2)²

                             = (2.5)²+ 6²

                             = 6.25 + 36

     Hypotenuse = [tex]\sqrt{42.25}[/tex]

                           = 6.5 mi.

     Therefore, total distance covered by Kelly = 6.5 + 2.5 + 6

                                                                             = 15 mi.

10). Amount of paper required to cover one desk of the class

     = Area of the trapezoid shown in the figure

     = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

      Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides of the trapezoid

      And 'h' is the distance between the parallel sides.

      By applying Pythagoras theorem in ΔPRT,

      PR² = RT² + PT²

      PT = [tex]\sqrt{PR^2-RT^2}[/tex]

      PT = [tex]\sqrt{(18)^2-2^2}[/tex]

            = [tex]\sqrt{324-4}[/tex]

            = [tex]\sqrt{320}[/tex]

            = 17.89 in.

      Area of the trapezoid PQRS = [tex]\frac{1}{2}(PQ+RS)(PT)[/tex]

                                                      = [tex]\frac{1}{2}(22+26)(17.89)[/tex]

                                                      = 429.36 in²

      Therefore, paper required to cover 30 desks = 30 × 429.36

                                                                                   = 12880.8 in²

Answer:

b= -15

Step-by-step explanation:

First combine like terms 9-16= -7

Next add 7 to both sides

Left 3b= -45

Finally divide

So b= -15

[tex]300[/tex] or [tex]+300[/tex]

Step-by-step explanation:

Given

300 feet above sea level

Required

Represent as an integer

Sea level implies 0 ft.

So, when a distance (300) is above the sea level, it means that the position is:

[tex]Position = 0 + 300[/tex]

[tex]Position = 300[/tex]

Hence, the position is 300 or +300

Step-by-step explanation:

Part A:

Rate of pay for David = [tex]\frac{\text{Change in earnings}}{\text{Change in hours worked}}[/tex]

                                            = [tex]\frac{3700-3200}{140-120}[/tex]

                                            = $25

Part B:

If he worked for number of hours = x

Then the function representing the earning will be,

f(x) = 25x + b

For an ordered pair (120, 3200),

3200 = 25(120) + b

b = 3200 - 3000

b = 200

Therefore, function will be,

f(x) = 25x + 200

Part C:

"Slope = 25" means the rate of change in earnings per hour is $25.

Similarly, y-intercept 'b = 200' will represent the fixed amount earned by David in addition to the per hour earnings.
