ella bought some key chains and spent a total of 24 each key chain cost the same whole dollar amount she bought between 7 and 11 key chains how many key chains did ella buy?

Answers

Answer 1

Answer:

Answer: there are 8 key chains Ella can buy.

Step-by-step explanation:

Since we have given that

Ella bought some key chain and spent a total of 24.

Each key chain cost the same whole dollar amount she bought between 7 and 11 key chains.

As we know that between 7 and 11, there is only 1 number which is factor of 24 i.e. 8

Hence, there are 8 key chains Ella can buy.

Answer 2

Answer: To solve this problem, you need to use a process of trial and error, and add up each number until you get 24 or above. If you get above, it is wrong. The only number that goes into 24 evenly is 8, so the answer is 8 keychains.

What is the correct classification of 7x2 + 9x + 4? Select one of the options below as your answer:A. monomial B. binomial C. trinomial

Answers

Answer:

The correct classification is trinomial.

Step-by-step explanation:

Given the equation

$7x^2+9x+4$

we have to choose the options.

Monomial is an algebraic expression containing one term, binomial with two terms and trinomial with 3 terms.

Now, the given expression

$7x^2+9x+4$

consisting of 3 terms therefore called trinomial.

Hence, the correct classification is trinomial.

B. binomial

this expression has two terms (whole numbers and a x-term

A spinner with 6 equally sized slices has 1 blue slice, 2 red slices, and 3 yellow slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a blue or red slice? Write your answer as a fraction in simplest form.

Answers

Answer:

1/2

Step-by-step explanation:

Step one:

given data

sample space

1 blue slice,

2 red slices, and

3 yellow slices

sample size= 1+2+3= 6

Required:

The probability that the dial stops on a blue or red slice

1. The probability that the dial stops on a blue = 1/6

2. The probability that the dial stops on a red= 2/6= 1/3

Hence The probability that the dial stops on a blue or red= 1/6+1/3

= 1+2/6

=3/6

=1/2
