Answer: 15%
Step-by-step explanation:
From the question, we are informed that a survey results of a middle school shows that 3/20 of the students played football.
The percentage of the students that play football in this schools would be calculated as multiplying the fraction by 100. This will be:
= 3/20 × 100
= 3 × 5
= 15%
Answer:
r < -12 and r > -6
Step-by-step explanation:
Hello!
First you find out the amount of balloons by adding them up
10 + 12 + 15 + 8 = 45
Then you add all the balloons that are not green
10 + 12 + 15 = 37
Then you put the amount of balloons that are not green over the total amount of balloons
The answer is 37/45
Hope this helps!
Sense -4 and +2 would be 6 digits away from each other, we would then have to figure out, what would 4 times x - 2 would equal "x".
We would do, 4×2 = 8.
8 - 2 = 6.
Sense 6 is the amount of how much -4 and +2 would be from each other, this would then mean that x would then equal 8.
Answer: d=5
Step-by-step explanation:
Arithmetic progression
An=a1+d(n-1)
An= nth term
A1= first term
D= common difference
N= nth position
We are given the 4th and 7th terms
For 4th term,n=4
A4=a1+d(4-1)
A4= 16
16= a1+d(4-1)
16= a1+3d........equation 1
For the 7th term,n=7
A7=a1+d(7-1)
A7= 31
31=a1+6d......equation 2
Bring them together
16=a1+3d
31=a1+6d
Subtract equation 1 from 2
So we have
15=3d
D=15/3
D=5
Therefore, the common difference is 5
