Triangle ABC is dilated by a scale factor of 1.5 to form Triangle DEF. Are Triangles ABC and DEF congruent? Why or why not?
Triss [41]

Answer:

Yes, they will be.

Step-by-step explanation:

Congruent means when they are the same shape and same size.

If triangle ABC is dilated to <u><em>form</em></u> triangle DEF, that means that they will have the same shape and the same size.

So yes Triangles ABC and DEF will be congruent to one another because they will be the same shape, and they will have the same size as well.

Hope this helped!

Find the volume of a right circular cone that has a height of 14.3 ft and a base with a diameter of 17.2 ft. Round your answer t
saveliy_v [14]

Answer:

Volume of the given cone is 1107.6 cubic feet.

Step-by-step explanation:

Formula to get the volume of a right circular cone is,

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

Here r = radius of the circular base

h = height of the cone

Now we put the values in the given formula

Volume = \frac{1}{3}\pi (8.6)^2(14.3)  [ radius = \frac{17.2}{2}=8.6 ]

             = \frac{1057.628\pi }{3}

             = 1107.55

             ≈ 1107.6 cubic feet

Therefore, volume of the given cone is 1107.6 cubic feet.

A survey of nonprofit organizations showed that online fundraising has increased in the past year. You want to estimate the popu
kakasveta [241]

Answer:

e. a point estimate

Step-by-step explanation:

When an estimate for the unknown population parameter is expressed by a single value it is called a point estimate.

Example : If we wish to find the height of a very large group of students on the basis of a sample and we find it to be 64 inches. 64 inches is the point estimate.

<em>Similarly the value given is the point estimate.</em>

Point estimate of the population parameter provides as an estimate a single value calculated from the sample that is likely to be close in value to the unknown parameter. It is to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.

Please help the image below with question!
Katena32 [7]

Answer:

6π units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Since we only require one half of the circumference, then

0.5C = πr

given diameter = 12 then r = 12 ÷ 2 = 6, then

arc length = π × 6 = 6π units
