The volume (V) of the cone is one-third of the product of its height (h) and area (A). 
                                    V = A x h = πr²h 
Now, if the radius is quadrupled and the height is reduced to 1/5, the equation will be,
                                  V2 = π(4r)²(1/5 h) = π(3.2)r²h
Thus, the second volume would be 3.2 time the first volume.

if the results of the survey were claimed to indicate that 7.7% of adults in the country who own digital cameras plan to replace
Elena L [17]

The above statement is inferential in its approach.

Step-by-step explanation:

Inferential results are deferred results meaning results are deduced from the above assumptions or survey.  

As per the results of the survey, 7.7% of adults in the country owning a digital camera and are in process to replace their camera in the coming 12 months.

This means that the survey formed the basis of the above-made deduction that of all the 7.7% adult who owns a camera is planning to replace it. Hence the statement is inferential in its approach.

Answer:

x = 19

Step-by-step explanation:

The angles of a triangle add to 180

U and S are equal since they are the base angles  and UT and ST are equal

S + T + U = 180

x + 26 + 90 + x+26 = 180

Combine like terms

2x +142 = 180

Subtract 142 from each side

2x = 38

Divide each side by 2

2x/2 = 38/2

x = 19

Caitlyn did 6/7 of the problems on her math correctly and 4 incorrectly. She did all the problems. How many were there?
Viefleur [7K]
If \frac{6}{7} were incorrect, it means that \frac{1}{7}=4 were correct
4*7=28
There were 28 problems ;)

What is the lcm of 6and 15
Maurinko [17]
LCM stands for least common multiple. We are being asked to find the lowest multiple that 6 and 15 have in common.

Multiples of a number (n) are integers that are the product of n and another number. Let's list the multiples of both 6 and 15:

6: 6, 12, 18, 24, 30, 36

15: 15, 30, 45, 60, 75, 90

The LCM of 6 and 15 is 30.
