Jamil finds that he reads 1/5 of his 115-page book in 1/4 hour

Answers

Answer:

He will read 92 pages in an hour going by the current rate at which he reads

Step-by-step explanation:

The complete question is as follows;

Jamil found that he reads 1/5 of his 115 - page book in 1/4 of an hour. At this rate how many pages does he read in an hour

We proceed as follows;

If he reads 1/5 of 115 in 1/4 hour

1/5 of 115 pages refer to 1/5 * 115 = 23 pages

This means that he reads 23 pages in quarter of an hour

So in an hours the number of pages he will read will be 23 * 4 = 92 pages

Tamara is reviewing recent orders at her deli to determine which meats she should order. She found that of 1,000 orders, 450 customers ordered turkey, 375 customers ordered ham, and 250 customers ordered neither turkey nor ham. Based on these data, how many of the next 1,000 customers will order both turkey and ham? Show your work and use complete sentences.

Answers

Tamara has 1000 orders of deli
=> 450 = ordered for turkey
=> 375 = ordered for ham
=> 250 = ordered for either ham and turkey

Now, let’s start calculating the possible answer:
=> 1000 – 250 (neither ham or turkey)
=> 750 remaining ham and turkey order
=> 450 ordered turkey and 375 ordered ham
=> 450 + 375 = 825 ordered for ham and turkey
=> 825 – 750 = 75

SO, it shows that there will be sure 75 ordered of neither ham nor turkey for the next 1000 order.



Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends and still had 2 chocolates left. Write an equation to determine the number of friends (x) at Jack's party.

Answers

Answer:

3x = 48

Step-by-step explanation:

To easily do this, we'll make the statement in mathematical form.

Let x represent the number of friends at Jack's wedding.

The equation would be:

3 * x = 50 - 2

3x = 48

x = 48 / 3

x = 16

Therefore, the equation to determine the number of friends (x) at Jack's party is expressed as:

3x = 48

List all factor for each number 100. 65. 70

Answers

The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100 .

The factors of 65 are 1, 5, 13, and 65 .

The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70 .
Factors of a number are those numbers which divide a number without leaving any remainder
The factors of 65 are 1,5, 13,65 because all of these can divide 65 without leaving any remainder
The factors of 70 are 1,2,5,7,10,14,35,70 since all of them can divide 70 without leaving any remainder
The factors of 100 are 1,2,4,5,10,20,25,50,100 since all these can divide 100 without leaving any remaider

To determine the area of a rectangle, one strategy is to split the rectangle into smaller pieces, and determine the smaller areas first. Explain how this strategy relates to binomial multiplication.

Answers

Area of the rectangle is determined by Binomial Multiplication as given below.

What is Binomial Multiplication ?

Binomial Multiplication follows FOIL method , Firsts , Outer terms , Inner Terms , Last Terms.

A rectangle is given and area of the rectangle has to be determined by splitting it into smaller rectangles.

Let the rectangle is of 5*3 ft

To determine the area the rectangle has been split into rectangles of 15 rectangles as seen in the figure attached.

Area of the smaller rectangle is given by Length * Breadth =  1*1

Let us consider x = 1

Then

The side of the rectangle will be ( x+4) ( x+2)

On solving this by FOIL

x² + 6x +8

Area = x² + 6x +8

Area = 1 + 6 + 8 = 15 sq.ft

Area of the bigger rectangle =  

= ( Area of 1st rectangle + Area of 2nd Rectangle + ...... +  Area of 15th Rectangle)

= 15 * ( Area of the smaller rectangle)

Area of the bigger rectangle  = 15 * ( 1 * 1)

Say you have a big rectangle. You can split that big rectangle up into little rectangles, say unit rectangles whose areas are 1, and then count up all those little rectangles to find the area of the larger rectangle. So for instance:
I have a rectangle that has an area of 4ft^2
I can split up that rectangle to smaller rectangles of 1ft^2
Then I can count how many smaller rectangles I have and deduce the area of the larger rectangle form that -> 1ft^2 * 4 = 4ft^2
