Options

David has 11 books and 27 DVDs.

David has 11 DVDs and 27 books.

David has 11 DVDs and 27 items total.

David has 11 books and 27 items total

Answer:

b. David has 27 books and 11 DVDs

Step-by-step explanation:

Given

Parameters: Books and DVDs

Let B represent number of books

Let D represent number of DVDs

From the question, we have that the ratio of the number of books that he owns to the number of DVDs that he owns as 27:11

This mean that

B : D = 27 : 11

By comparing the position of items at the left hand side (B and D) relative to the items at the right hand side (i.e 27 and 11).

We have that

B = 27 and

D = 11

Recall that

B represent number of books and

D represent number of DVDs

This means that

Number of books = 27

Number of DVDs = 11

So, we can conclude that David has 27 books and 11 DVDs

Which quadratic equation is equivalent to (x – 4)2 – (x – 4) – 6 = 0?
Viktor [21]

I hope choices must be given in the problem.

I am showing the method to find the equivalent equation of the above equation. You can match with your given choices.

First step is to expand the first term. So,

(x-4)² = (x - 4)(x - 4) Since a²= a*a

= x² - 4x - 4x + 4 * 4 By multiplying.

= x² -8x + 16 Combine the like terms.

So, (x - 4)² - (x -4) - 6

= x² - 8x + 16 - x + 4 - 6

= x² - 9x + 14 Combine the like terms.

So, equivalent equation of the above equation is x² - 9x + 14 = 0.

A runner increases his velocity from 0 m/s to 20 m/s in 2.0s. What was his average acceleration?
xenn [34]

change in velocity = 20 - 0 = 20

change in time = 2 seconds

Divide the change in velocity over the change in time: 20/2 = 10

The average acceleration is 10 m/s^2

I.e, each second, the speed increases by 10 m/s

the local volleyball team hosts a concession stand to raise money. They can spend $120 to purchase popcorn, candy, and drinks. t
Art [367]
To solve this question, I did an equation:
0.75x + 1.20y = 120
0.75(95) + 1.20(35) = 120
Then multiply:
71.25 + 42 = 120
Now to check:
71.25 + 42 = 113.25
Answer: 120 - 113.25 = $6.75 Hope this helps
