If (20,8) and (25, 10) belong to a proportional relationship, what is the constant of proportionality
A. 5/2
B. 3/2
C. 1/2
D. 2/5
Answer:
The proportionality constant is 2/5
Step-by-step explanation:
Here, we want to get the proportionality constant
Let us view the two points as being points on a line
The constant of proportionality will be the slope of the line that connects the two points
Mathematically, we can use the formula for the slope of a line
We have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (20,8)
(x2,y2)= (25,10)
m = (10-8)/(25-20) = 2/5

find the size of angle q if it is five times it's supplement
Answer:
q = 150
Step-by-step explanation:
Supplementary angles are angles that form a straight line and have a sum of 180 degrees, e.g. 120 and 60. If its supplement is thirty, and angle q is five times its supplement, it's 150. We know this is correct because 150 + 30 = 180, which is what we need for a supplementary angle.
The measure of one side of a square is (s+3) inches long. which pair of expressions both represent the perimeter of this square?
Answer:
D. 4(s + 3) & (s + 3) + (s + 3) + (s + 3) + (s + 3)
Step-by-step explanation:
We know this is a square (which is a polygon, which requires at least 3 sides), so A & B are out. C is also out because of the first expression. All 4 sides are s + 3; what the first expression on C is saying is we're adding a 5th side of 3 to 4 sides with length s. That leaves D as our answer. Bonus: Another expression that could work for this is 4s + 12 (which is both of D's expressions simplified.).
Which one of the following sets of ordered pairs determines a line whose slope is 4/3? A. (5,-3)(2,3)
B. (3,10) (-3,-2)
C. (3,-5) (-3,-7)
D. (-1,-3) (5,5
Given statement solution is :- The set of ordered pairs (-1, -3) and (5, 5) determine a line with a slope of 4/3, according to the given statement's answer.
To determine the slope of a line given two ordered pairs (x1, y1) and (x2, y2), we use the formula:
slope is equal to y2 - y1 / x2 - x1.
Let's calculate the slopes for each set of ordered pairs:
A. (5, -3) (2, 3)
slope = (3 - (-3)) / (2 - 5)
= 6 / (-3)
= -2
B. (3, 10) (-3, -2)
slope = (-2 - 10) / (-3 - 3)
= -12 / (-6)
= 2
C. (3, -5) (-3, -7)
slope = (-7 - (-5)) / (-3 - 3)
= (-2) / (-6)
= 1/3
D. (-1, -3) (5, 5)
slope = (5 - (-3)) / (5 - (-1))
= 8 / 6
= 4/3
Option D's set of ordered pairs, (-1, -3) and (5, 5), results in a line with a slope of 4/3.

Suppose a city with population 800,000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 17 years.
Answer:
1,752,000
Step-by-step explanation:
1. First you have to take the 7% and multiply that by the years whish is 17 so that way you know your total percentage of growth which is 119%
2. Second you then need to find how much 1% is to find out our total growth in population so you take 800,000 and divide that by 100 since there's only 100% and you get 8,000.
3. Now you take the 8,000 and multiply that by the percentage of the growth that you have which is 8,000*119 and you get 952,000
4. Lastly all you have to do is add the growth of the population to the population you already have so 800,000+952,000=1,752,000

What fraction of the time did Snowy Pines get at least 14 inches of snow?
Answer:1/4
Step-by-step explanation:
I got it right.
Fraction of time that the Snowy Pines get at least 14 inches of snow is 1/4.
What is Box Plot?Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.
Given is a box and whisker plot.
We know that box plot represents the first quartile, median and third quartile of the data set.
First quartile is where the 25% of the data points lie.
Median is where the 50% of the data points lie.
Third quartile is where 75% of the data points lie.
Above 14 inches lie the third or upper quartile.
75% of the data points lies below 14.
Data points which are at least 14 inches is 14 or more than 14.
Snowy Pines get at least 14 inches of snow for 100% - 75% = 25% of data points.
Fraction = 25/100 = 1/4
Hence the required fraction of time is 1/4.

The graph shows how the height of a balloon is changing over time.
BALLOON HEIGHT
Height
Time
Which quantity is given by the slope of the line on the graph?
A
the time the balloon stays in the air
B
the rate at which the balloon is rising
С
the final height of the balloon
D
the starting height of the balloon
Answer:
B. The rate at which the balloon is rising.
Step-by-step explanation:
Mathematically speaking, the slope of the line represents the change in dependent variable (Height) divided by the change in independent variable (Time). According to the graph, a postive change in time leads to a positive change in height, meaning that slope is positive. Physically speaking, the slope represents the rate of change at which the height of the ballon is rising.
Hence, correct answer is B.

Jillian is making a paper flower motif for an art project the flower she is making has 4 petals each petal is made of three semicircles as shown below, What is the area of the paper flower?
Answer:
[tex]Area = 216\pi[/tex]
Step-by-step explanation:
Given
See attachment for semicircles
Required
The area of the paper
First, calculate the area of each petal.
The petal is made up of:
1. Semicircle of diameter 12cm
2. Semicircle of diameter 18cm (i.e. 12cm + 6cm)
3. A hole semicircle of diameter 6cm
The area of each semicircle is calculated as follows:
[tex]Area = \frac{\pi r^2}{2}[/tex]
For (1):
[tex]d = 12cm[/tex] --- diameter
[tex]r = 0.5 * d = 0.5* 12cm = 6cm[/tex] --- radius
So:
[tex]A_1 = \frac{\pi * 6^2}{2}[/tex]
Evaluate the exponent
[tex]A_1 = \frac{\pi * 36}{2}[/tex]
Divide 36 by 2
[tex]A_1 = 18\pi[/tex]
For (2):
[tex]d = 18cm[/tex]
[tex]r = 0.5* 18cm = 9cm[/tex]
So:
[tex]A_2 = \frac{\pi * 9^2}{2}[/tex]
[tex]A_2 = \frac{\pi * 81}{2}[/tex]
[tex]A_2 = 40.5\pi[/tex]
For (3):
[tex]d = 6cm[/tex]
[tex]r = 0.5* 6cm = 3cm[/tex]
So:
[tex]A_3 = \frac{\pi * 3^2}{2}[/tex]
[tex]A_3 = \frac{\pi * 9}{2}[/tex]
[tex]A_3 = 4.5\pi[/tex]
Recall that (3) is a hole.
So, the area (A) of a petal is:
[tex]A = A_1 + A_2 - A_3[/tex]
[tex]A = 18\pi + 40.5\pi - 4.5\pi[/tex]
[tex]A = 54\pi[/tex]
The paper uses 4 petals.
So:
[tex]Area = 4 * A[/tex]
[tex]Area = 4 * 54\pi[/tex]
[tex]Area = 216\pi[/tex]

About 150 million tons of plastic waste is in the world’s oceans. If each 001/B system can clean up 10,000 tons of plastic per year, how many systems would have to be deployed to meet the Ocean Cleanup’s goal of cleaning the oceans by 2040? Write a y = mx equation to solve.
Answer:
750 systems are needed in 20 years to clean 150 million tons wastes.
Step-by-step explanation:
Total waste = 150 million tons
Waste cleaned each year by 1 machine = 10,000 tons
No of years from 2020 to 2040 = 20 years
Waste cleaned in 20 years by 1 machine = 20* 10,000= 200,000 tons
Machines needed in 20 years to clean 150 million tons wastes using
y= mx ( where m= number of machines)
and x is the waste cleaned in 20 years by 1 machine
150,000,000 = m 200,000
or m = 150,000,000 /200,000
m= 750
The results of a study exhibit response bias. Select the statement that best describes the bias in the study.
There were not enough subjects who chose to respond to a survey that was sent as part of the study.
The interviewer for the study was the boss of the subjects.
The interviewer for the study did not record the responses of the subjects accurately.
* There was a significant amount of people who declined to participate in the study.
Answer:
"The interviewer for the study did not record the responses of the subjects accurately." I believe this is most pertinent. B, or the boss of the subjects, could have been an answer, but if all members associated in the study exhibit the similar level of response bias based upon superior employers, then the study remains somewhat accurate, but C, or inaccurate record of responses, would remain biased entirely.
