Answer:

C) 9

Step-by-step explanation:

Note that the factors are already given to you:

54 = 2 * 3 * 3 * 3

81 = 3 * 3 * 3 * 3

Note that they all have 3 3's. However, there is not a choice for 27 (as 3 * 3 * 3 = 27), therefore, choose the next option: 3 * 3 = 9

C) 9 is your answer.

How to solve this showing all work ! Also explain why they aren’t polynomials if you can :)
Lesechka [4]

Polynomials are linear combinations of positive integer powers. For example,

x^{100}+30x^2-\sqrt 2\,x+21

is a polynomial, but

-x^{-1}-4x^\pi+x^{3/2}

is not.

(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of a and b is k_1a+k_2b, where k_1,k_2 are any numbers.)

8x^2-18\sqrt x+5x-3 is not a polynomial; the offending term is -18\sqrt x, or -18x^{1/2}.

Which of the following questions is a statistical question?
MariettaO [177]

Answer:

Step-by-step explanation:

Im not full sure what the answer is but I do know that A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer. For example, "How many minutes do 6th grade students typically spend on homework each week?" is a statistical question.

I think that a one of the answers may be number 3 but im not 100%

Carson's wheelbarrow can hold 345 pounds. If he has 121 pound of rock in the wheelbarrow what number of pounds p can he pull wit
dangina [55]

Answer:

p\leq 224\ lb

The maximum number of pounds p is 224

Step-by-step explanation:

Let

p ----> the maximum number of pounds he can pull without going over the weight limit

we know that

121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds

In this problem the word "at most" means "less than or equal to"

so

The inequality that represent this situation is

p+121\leq 345

solve for p

subtract 121 both sides

p\leq 345-121

p\leq 224\ lb

therefore

The maximum number of pounds is 224
