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.
In 2010, the population of a city was 224,000. From 2010 to 2015, the population grew by 6%. From 2015 to 2020, it fell by 4%. How much did the population grow from 2010 to 2015, to the nearest 100 people?
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.
What is the percentage?
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.

Step-by-step explanation:
Answer:
Movie Rental B is better to buy. It's cheaper by .75 cents.
Step-by-step explanation:
Solving Movie Rental A
To find the unit rate of this one, we divide the dollars and the rentals.
So, 15 ÷ 3 = 5
Unit Rate for Movie Rental A is 5
Solving Movie Rental B
Same as Movie Rental A, divide the dollars and the Rentals.
8.5 ÷ 2 = 4.25
The number with the less amount is cheaper so
4.25 is less than 5

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

David keeps records of his monthly earnings. Last month he worked 140 hours and earned $3700. This month he worked 120 hours and earned $3200.
Answer:
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.

Write an integer to show 300 feet above sea level
Answer:
[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
