How many smaller rectangles are there in an area model that represents 27 times 83 Why? What are their dimensions?

ipn [44]

Answer;

4 small rectangles

That is; 20 by 80, 20 by 3, 7 by 80, and 7 by 3.

Explanation;

We have; 27 by 83

We can decompose 27 into 10s and 1s to get; 20 + 7 , and

also decompose, 83 into 10s and 1s to get; 80 + 3;

But we know area is given by length times width, thus;

we have rectangles; 20 × 80, 20 × 3, 7 × 80 and 7 × 3

-The total area will be given by the sum of the area of the four triangles that is equivalent to 83 × 27.

The inequality x - y > 0 is satisfied by point (-1, 1).<br><br> T/F

Mekhanik [1.2K]

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

Step-by-step explanation:

We need to identify the point (-1,1) satisfies the inequality x - y > 0

Solving:

The value of x = -1 and y =1

Putting values in the inequality:

$x-y>0\\-1-1>0\\-2>0\,\,false$

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

Andrew needs to print a document that is 180 pages long. How much longer will it take to print the document on a sure fire print

baherus [9]

A centroid printer is a fast-print printer with a speed of 20 pages per minute. A surefire printer is also fast but it's a bit slower with a printing speed of 15 pages per minute. So,
180 pages / (20 pages per minute) - 180 / (15 pages per minute)
= 36 minutes
It would take 36 minutes faster for the centroid printer to print the document than a surefire printer.
