How can an area model help you set
up an equation for a problem situation?

Answers

Answer 1

Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the  or the  and  define the length and width of the rectangle.

We can break one large  of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the  or quotient.

Step-by-step explanation:

For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

Answer:

6.5 minutes

Step-by-step explanation:

T0 = initial time

T1=T0 - 2.1

T2=T1 x 0.9= 3.96

T1 = 3.96/.9= 4.4

T0=T1+2.1=6.5

what is the decimal multiplier to increase by 75%​

Answers

Answer:

1.75

Step-by-step explanation:

Let the number to be increased be x

If x is to be increased by 75% then the result after the increase T may be expressed as

T = x + 75% * x

T = x + 0.75x

T = 1.75x

As such when x is increased by 75%, the result is the product of x and 1.75 (the multiplier).
