The <em>correct answer</em> is:

B) 7.

Explanation:

A set is a subset of itself. This is 1 subset.

Each individual letter can be taken as a subset; this gives us {A}, {B}, and {C}. This is 3 more subsets for 4 so far.

{A,B}, {A,C}, and {B,C} are also subsets. This makes 3 more, for a total of 7.

The total number of subsets of {A, B, C} is 8. It can be found by cubing 2 and the resulting answer will definitely be 8. The correct option among all the options that are given in the question is the third option or option "c". I hope that this answer has come to your help.

What is the solution for the equation 5/3b^3-2b-5=2/b3-2
irinina [24]

Answer:

Option C is correct.

Step-by-step explanation:

Given Equation:

\frac{5}{3b^3-2b^2-5}=\frac{2}{b^3-2}

To find: Solution of the Equation.

Consider,

5(b^3-2)=2(3b^3-2b^2-5)

5b^3-10=6b^3-4b^2-10

6b^3-5b^3-4b^2+10-10=0

b^3-4b^2=0

b^2(b-4)=0

b² = 0   ⇒ b = 0

b - 4 = 0 ⇒ b = 4

Therefore, Option C is correct.

Answer:

The 3rd option

Step-by-step explanation:

To prove that 2 triangles are similar, we need to prove that 2 pairs of their angle measurements are congruent.

This is because all triangles have 180 degrees, so if 2 pairs are congruent, the remaining angles will also be congruent

We know that m<D=m<E

We also know that m<DCA=m<ECB because they are vertical angles.

Vertical angles are always congruent.

Therefore, the triangles are similar.

The correct similarity statement would be 1, since <D corresponds with <E.

Now let's look at the 3rd Statement. To prove that two lines are similar, we would have to prove that their alternate interior angles are congruent.

A pair of alternate interior angles would be <D and B or or <E  and <A

There is no way to prove this, since we do not know any of the angle  or that measurements or if the triangles are isosceles triangles.

Hence, the correct choice would be 1 only.

In this swimming pool design, explain how to find the area of the pool's surface. ​
Svetllana [295]
With a square or rectangular shape, the formula for figuring out how big an area is is simple: multiply the length and width of the shape by the square feet is the surface area of a pool that is feet long and feet wide (8x 10).

True or False: In scientific notation a number is written m X 10^w where m is between 1.000 and 9.999...
Bogdan [553]

Answer: True

Step-by-step explanation:

We try to keep the number greater than 1 and lower than 10, so between 1, and 9.

For example: 3545346 would be 3.5x10^6

you can see 3.5 is between 1 and 9
