A)
The number of tickets is decreasing by 3% each year.
B)
The number of tickets is decreasing by 97% each year.
The number of tickets is increasing by 3% each year.
D
The number of tickets is increasing by 979% each year.
Answer:
The number of tickets is increasing by 97% each year
Step-by-step explanation:
From the given word problem, the smaller number is 5
Let's assume the smaller number is represented by x and the larger number is represented by y.
According to the given information in the word problem, the difference between the two numbers is 25. This can be expressed as:
y - x = 25 (Equation 1)
It is also stated that the smaller number is 1/6th of the larger number:
x = (1/6) * y (Equation 2)
To find the value of the smaller number (x), we can substitute Equation 2 into Equation 1:
y - (1/6) * y = 25
Multiplying through by 6 to eliminate the fraction:
6y - y = 150
5y = 150
Dividing both sides by 5:
y = 30
Substituting the value of y back into Equation 2:
x = (1/6) * 30 = 5
Therefore, the value of the smaller number is 5.

#SPJ6
line passing through (-6.10)
with a slope of -1.
Answer:
y= -1x +4
Step-by-step explanation:
So if you meant (-6,10) then I have solved it.
Writing this in y= mx+b form we already have M
y= -1x + b
So let’s substitute by putting in then y and x
10 = -1(-6) + b
10 -6= 6 -6+ b
4 = b
Answer:
D The range in shelter A is 22 and the range in Shelter B is 18
Step-by-step explanation:
All you have to do is look at the start of the line and the end of the line and then subtract it.
30 - 8 = 22
28 - 10 = 18
C. A survey of 70 teachers showed that 21 of them have a second job.
D. A survey of 80 teachers showed that 32 of them have a second job.
In math class, 4 students complete individual surveys to determine the percentage of high school teachers that have a second job. Which two surveys show proportional results?
A) A and B
B) B and D
C) A and D
D) B and C
Answer:
Correct option is:
D) B and C
Step-by-step explanation:
A. A survey of 110 teachers showed that 28 of them have a second job.
B. A survey of 90 teachers showed that 27 of them have a second job.
C. A survey of 70 teachers showed that 21 of them have a second job.
D. A survey of 80 teachers showed that 32 of them have a second job.
Percentage of teachers having second job is calculated by the formula:
So, percentage of second job teachers of survey A,B,C and D is:
A B C D
Percentage 25.45% 30% 30% 40%
Hence, two surveys that are proportional are
B and C
Hence, Correct option is:
D) B and C
