The ratio of people to books in a classroom is 10:4 what is the unit rate of people per book
Alex73 [517]

Answer:

Unit rate of people per book = 2.5

Step by step explanation:

Given:

Number of peoples =  10

Number of books = 4

Their ratios = 10 : 4

We have to find the unit rate of people per book.

To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.

Or

For this we will follow the unitary method:

For 4 book there are 10 persons.

For 1 book there will be \frac{10}{4} persons.

So,

The numeric value = \frac{10}{4}

                               = 2.5

There are 2.5 people per book and that it also the unit rate of people per book.

When can we use the method of extracting the square root in solving the roots of quadratic equations?​
viva [34]

Answer:

This is the “best” method whenever the quadratic equation only contains x2 terms.

The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side.

step by step: but in order to solve a quadratic using the square root principle the problem must be in the correct form. To solve a quadratic using the square root principle the quadratic must be in vertex form, a(x – h)2 + k.

KATRIN_1 [288]

Answer:

(a)Bill's Total piecework pay =$500

(b)Amount owed by his boss=$26

Bill receives 25 Cents=$0.25 for every document

Therefore for x documents, Bill should receive: $0.25x

If Bill prepared 2000 documents for mailing

x=2000

The amount he should receive = $0.25 X 2000 =$500

(a)Bill's Total piecework pay =$500

(b)Amount owed by his boss

=500-474

=$26
