jonny [76]

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

The circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. What is the
marin [14]

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.

V=\frac{1}{3}\pi r^2 h, 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 r=\frac{7}{2}.

V=\frac{1}{3}\pi\cdot (\frac{7}{2})^2\cdot 10

V=\frac{1}{3}\pi\cdot (\frac{49}{4})\cdot 10

V=128.2817

V\approx 128.3

Therefore, the volume of the cone would be approximately 128.3 cubic cm.

Nataly [62]

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
