The table shows the participation in a school's debate club during the last four years.
Year 1 2 3 4
Students 14 19 25 33
Between which two years did the club see the greatest growth? By what percent did it grow?
A. The greatest growth was between years 3 and 4. The growth between those years was about 32%.
B. The greatest growth was between years 1 and 2. The growth between those years was about 5%.
C. The greatest growth was between years 3 and 4. The growth between those years was about 8%.
D. The greatest growth was between years 1 and 2. The growth between those years was about 36%.
Answer:
D
Step-by-step explanation:
19 - 14 = 5 / 14 x 100 = 35.714 > 36%
The other values by calculating the percent increase were
(from 2-3) = 31.57%
(from 3-4) = 32%
Greatest growth was between years 3 and 4. The growth between those years was about 32%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given table is participation in a school's debate club during the last four years.
Year 1 2 3 4
Students 14 19 25 33
We need to find between which two years did the club see the greatest growth.
From year 1 and 2 the growth is increased by 5 (19-14)
year 2 and 3 the growth is increased by 6 (25-19)
year 3 and 4 the growth is increased by 8 (33-25)
So between 3 and 4 there is greatest growth.
Now let us find the percentage of the growth.
33-25/25
0.32×100
32%
Hence, greatest growth was between years 3 and 4. The growth between those years was about 32%.

What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.
Answer:
-1/1
Step-by-step explanation:
The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.
(-2)-(0) / (0)-(-2) = -2 / 2
the denominater is a possitive two because, when you subtract a negative number, that number becomes positive and you now add it due to the distributive property. 0-(1)(-2) = -2 x -1 = 2

Jason is traveling by car from his home to his office. He has gone 3.5 miles so far. From this point on, he can cover 100 miles every 2 hours. What is the equation of a line that models the total miles traveled, y, in x hours after this point?
A.
y = 100x + 3.5
B.
y = 100x – 3.5
C.
y = 50x + 3.5
D.
y = -50x + 3.5
answer: 50x +3.5
Step-by-step explanation:
100 miles divided by 2 hours is 50 miles per hour, and he has already gone 3.5 miles, so the answer would be y= 50x +3.5

Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.
g(x) = _______________________
Answer:
1 and 1/3
Step-by-step explanation:
Fx equals 4x-6
Add six to both sides
6 equals 4X
Divide both sides by 4
2/3 equals x
Then GX equals f (2x)
Two times 2/3 is 1 and 1/3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given that f(x) = 4x − 6 and g(x) = f(2x), then;
We have to Add six to both sides;
f(x) = 4x − 6
6 = 4X
Now Divide both sides by 4;
2/3 = x
Then G(X ) is equals to f (2x)
Now, 2( 2/3 ) = 1 /3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

Which of the following describes two triangles that are similar to one another?
We have to determine, which of the following triangle is similar to another one.
Two similar triangle are always congruent. Two figures are similar if they have the same shape and size.
Two triangles are similar if their corresponding sides are proportional. Two polygons are similar if their corresponding side are proportional.
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
Both triangles are similar by SSS theorem, because all three pairs are in proportion,
To calculate the proportion of sides,
Triangle 1; m1 = 67, m2 = 15Triangle 2 ; m1 = 15 , m2 = 95
[tex]\dfrac{67}{15}= \dfrac{15}{95}[/tex]
Thus the angles are not proportion then the triangle are not similar.
Triangle 1; m1 = 24, m2 = 101Triangle 2 ; m1 = 65, m2 = 101
[tex]\dfrac{24}{65}= \dfrac{101}{101}[/tex]
Thus the angles are not proportion then the triangle are not similar.
Triangle 1; m1 = 45, m2 = 80
Triangle 2 ; m1 = 59 , m2 = 45
[tex]\dfrac{45}{59}= \dfrac{80}{45}[/tex]
Thus the angles are not proportion then the triangle are not similar.
Triangle 1; m1 = 71, m2 = 32Triangle 2 ; m1 = 71 , m2 =77
[tex]\dfrac{71}{71}= \dfrac{32}{77}[/tex]
Thus the angles are in same proportion then the triangle are similar.

The measure of the exterior angle is ________
PLEASE ANSWER ASAP!!!!
Find the measures of two supplementary angles if their measures are in the given ratio.
3:7
Two supplementary angles are in the ratio 3:7. Find the angles ?
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Measure of angles are 54° and 126°.
What is Supplementary angle?
Sum of two or more angles are 180 degrees then, the angles are called supplementary angle.
Given that;
The ratio of angles are 3 : 7.
Now,
Let the two angles be 3x and 7x.
Since, Supplementary angles are add up to 180 degrees.
So,
3x + 7x = 180
10x = 180
x = 18
So, First angle of supplemental angles = 3x
= 3 × 18
= 54
And, Second angle of supplemental angles = 7x
= 7 × 18
= 126
Thus, Measure of angles are 54° and 126°.
