Answer:
26
Step-by-step explanation:
h represents highschool members
m represents middle school members
42 = h+m
h = 2m-6
Substitute h for 2m-6 in first equation:
42 = (2m-6)+m
Solve for m:
42 =3m-6
48 = 3m
m = 16
Subsitute 16 for m in second equation:
h = 2(16)-6
Solve for h:
h = 32-6
h = 26
Answer:
4
Step-by-step explanation:
We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.
We will use volume of cone formula to solve our given problem.
, where
r = Radius of cone,
h = Height of cone.
We know that diameter is two times the radius, so radius will be half of diameter that is 
.
Therefore, the volume of the cone would be approximately 128.3 cubic cm.
Answer:
9x+3x=12x
180/12=15
9 x 15= 135
3 x 15= 45
135+45=180
x=15

Answer:
- <em>B) 41 − 45; 46 − 50; 51 − 55; 56 − 60 </em>
Explanation:
When you build a <em>histogram </em>the intervals must be of the same size. About 4 to 8 intervals is good but it also depends on the number of data and the range of those data.
Option D has only two intervals. That is too few. Thus, this is discarded. Three intervals also seems few. Thus, option C, is not good.
The option A shows intervals of different size:
- 46 - 41 = 4
- 49 - 46 = 3
- 52 - 49 = 3
- 56 - 53 = 3
Thus, this is not good either.
The optio B seems good:
Interval Frequency
- 45 - 41 = 4 3
- 50 - 46 = 4 4
- 55 - 51 = 4 4
- 60 - 56 = 4 1
Hence, the correct answer is B) 41 − 45; 46 − 50; 51 − 55; 56 − 60
