Vikki [24]4 years ago

The answer is false.

The formula for the SA of a cone is \pi r^{2}+\pi rl where <em>r</em> is the radius of the base and <em>l</em> is the slant height.
Since we have both the slant's height and the radius of the base we can answer this just by plugging numbers in;
SA=\pi r^{2}+\pi rl\\&#10;SA=\pi (2^{2})+\pi (2)(6)\\&#10;SA=4\pi+12\pi\\&#10;SA=16\pi\\
16\pi≈50.2654...

So your answer is false.

Write a word problem that would have the equation 8x - 4 = 28
xxMikexx [17]

Answer:

John's mother has the present age that is four less than the 8 times the present age of John.

If his mother has the age of 28 years now, then find John's present age.

Step-by-step explanation:

We have to write a word problem that would have the equation 8x - 4 = 28.

John's mother has the present age that is four less than the 8 times the present age of John.

If his mother has the age of 28 years now, then find John's present age.

So, if we consider the age of John as x years, then we will get the equation as 8x - 4 = 28. (Answer)

PLEASEEEE HELPP Enrollment in a dance studio has grown exponentially since the studio opened. A graph depicting this growth is s
marishachu [46]

Answer:

  25%

Step-by-step explanation:

The first doubling, from 20 to 40 occurs in a little more than 3 years, so the multiplier each year is a little less than 2^(1/3) ≈ 1.26. That is, each year is a little less than 26% more than the previous year.

The graph also goes near the point (8, 120), so grows by a factor of 6 in 8 years. That suggests a multiplier of 6^(1/8) ≈ 1.251. Each year is about 25.1% more than the previous year.

Both of these multipliers represent yearly growth rates near 25%.

___

Using the "rule of 72", the product of doubling time and percentage growth is about 72. So, for a doubling time of 3 years, the percentage growth is predicted to be near 72/3 = 24 percent.

All of these estimates help you choose the correct answer: 25%.
