What is the question you have?
Given:
First side(A): 2B - 7
Second side(B): B
Third side(C): B + 4
Plug in values:
A + B + C = 80
2B - 7 + B + B + 4 = 80
If you look at the coefficients only, you can rewrite the equation like this:
2B + B + B - 7 + 4 = 80
This means that 4B - 7 + 4 = 80
=4B - 3 = 80
= 4B = 80 + 3
B = 83/4, so you can either write B as 83/4 or as 20.75.
Checking your work:
A: 2(20.75) - 7 = 34.5
B: 20.75
C: 4 + 20.75 = 24.75
34.5 + 20.75 + 24.75 = 80cm.
Hope this helped.
The height of the right cone is 10.68 unit
<h3>What is Volume ?</h3>
Volume is defined as the space occupied by a three dimensional object.
Volume of a right cone is given by
V = π r²h/3
C = 2 π r
r = 247/2 π
3 * 17287 = π r²h
3 * 17287 = π *(247/2 π )²h
h = 51861 *π *4/61009
h = 10.68 unit
Therefore the height of the right cone is 10.68 unit.

Answer:
Weight on 1 may = 104 lb
Step-by-step explanation:
Given:
Weight on last may = 110 lb
Weight gain for to week = 2 x 19 = 38 lb
Weight lose for to week = 2 x 22 = 44 lb
Find:
Weight on 1 may
Computation:
Weight on 1 may = Weight on last may - Weight gain for to week + Weight lose for to week
Weight on 1 may = 110 - 44 + 38
Weight on 1 may = 104 lb
Answer:
- 3.5
- 2
- B
- A
Step-by-step explanation:
Middle School:
Find the median by arranging the data points from smallest to largest.
1, 1, 1, 3, 4, 4, 5, 6 (Take the average of the two points in the middle, 3 and 4)
7/2 = 3.5
High School:
1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 4 (Take the average of the two points in the middle, 2 and 2)
4/2 = 2
Most of the points in the middle school plot are four or less.
A (High school students had more variation.)
