There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?
Answers
There is an increase in total participants.
What is unitary method?
The unitarymethod is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.

Answer: y=-2x+8
Step-by-step explanation:
To find the slope of the line, you would use . With the 2 points we are given , we can plug it into this equation to find the slope.
Now we know the slope is -2. To find the y-intercept, we know that the x value is 0. We are given that one of the points is (0,8). That means 8 is our y-intercept.
The final equation we get is y=-2x+8.
Answer:
y= -2×+8
Step-by-step explanation:
find m(slope)
y2-y1 over x2-x1
substitute using (0,8) and (4,0)
m=-2
y=mx+b
substitute x and y to find b using either (0,8) or (4,0)
0=-2(4) + b
0= -8 +b
0+8= -8+8 +b
8=b
y=-2x+8

a. write a rule for the sequence using centimeters. The initial height is given by term n = 1
For this case we have a sequence of the form:
Where
a0: initial height
r: rate of change
n: number of paths
On the other hand we have the following conversion:
1 meter = 100 centimeters
Therefore we have:
Thus, the general rule for the sequence in centimeters is:
Answer:
a rule for the sequence using centimeters is:
b. what height will the ball be at the top of the sixth path
For this case, we substitute the value of n = 6 in the equation obtained in part a.
We have then:
Answer:
the height of the ball will be 27.06 at the top of the sixth path
an = a1 r^(n-1)
with a1 as 1.5
and r = 0.71
So,
a.
The rule for sequence is:
an = 1.5 (0.71)^(n - 1)
b.
After the sixth path, the height of the ball at the top is
a6 = 1.5 (0.71)^(6 - 1)
a6 = 0.27 m
