Answer:

5. R = 6

6. D = 22

Step-by-step explanation:

5. The area formula is πr2.

If πr2=36π,

π can be canceled out from both sides.

Then, it is r2=36.

If we square root both sides, we get:

r=6 .

Therefore, the radius of your circle is 6.

6.A = 121 π

A = r² π

r² π = 121 π

r = √ 121 = 11

The diameter: d = 2 r = 2 * 11 = 22 units

In the spinner below, what is true about the probability of landing on 3 and the probability of landing on 4?

Karo-lina-s [1.5K]

Answer:

C.The probabilities are equal.

The above statement is the only TRUE statement.

Step-by-step explanation:

Here, the given number of total possibilities are { 0,1,2,3,4,5,6,7,8,9}

So, number of total outcomes = 10

Let E : Event of spinner landing on 3

and E' : Even of spinner landing on 4

{Probability of Event E} = $\frac{\textrm{Total number of favorable outcomes}}{\textrm{Toatl outcomes}}$

$\implies P(E) = \frac{1}{10}$

⇒ P( landing on 3 ) = 1/10

and $P(E') = \frac{1}{10}$

P( landing on 4 ) = 1/10

Now, the given statements are

A.The probability of landing on 3 is less than probability of landing on 4.

FALSE, as both the probabilities are equal to 1/10.

B.The probability of landing on 3 is greater than probability of landing on 4.

FALSE, as both have same probabilities.

C.The probabilities are equal.

TRUE, both have same probability = 1/10

D.The probabilities cannot be predicted

FALSE, the probability are predictable.

Factor each of the following. Remember: It is the reverse of the distributive property and your first step is to find the greate

vaieri [72.5K]

To factor using the reverse of the distributive property, find what common factor the numbers have and what common factor the variables have.

10.

-8x - 16

8 is a factor of both -8 and 16.
The first term has x, but the second term does not, so there is no common variable. The only common factor is 8, or -8.

Factor out a -8:

-8x - 16 = -8(x + 2)

To see if the factorization is correct, multiply the answer using the distributive property. If you get the original expression, then the factorization is correct.

11.

w^2 - 4w

The first term only has a factor of 1. The second term has a 4. There is no common factor between 1 and 4 except for 1, so there is no number you can factor out. The first term has w^2. The second term has w. Both terms have a common factor of w. We can factor out w from both terms.

w^2 - 4w = w(w - 4)

12.

4s + 10rs

4 and 10 have a common factor of 2.
s and rs have a common factor of s.
2 times s is 2s, so the common factor is 2s.
We now factor out 2s

4s + 10rs = 2s(2 + 5r)
