lord [1]

Answer:

showing bellow

Step-by-step explanation:

Let me use an exsample to show this.

Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster. He enlarges the stamp using a scale of 2 inches to 1 centimeter. If the actual length of the stamp is 3 centimeters and its width is 5 centimeters, what are the dimensions of the scale picture?

6 inches by 10 inches

Step-by-step explanation:

It tells us that the scale is 2 In: 1 cm so we know that for every centimeter long or wide the stamp is the enlardged scale is two inches.

2 times 3 is 6. 6 inches. we are multiplying two inches by the number of centimeter long it is.

5 times 2 is 10 inches. we are multiplying two inches by the number of centimeter wide it is.

therefore the enlarged stamp is 6 In by 10 In.

Hope this helps :)

For the given decimal −0.009, find the two integers closest to it.
asambeis [7]

Answer:

The two integers closest to -0.009 are -1 and 0

Step-by-step explanation:

we have the number

-0.009

Convert to fraction number

-0.009=-\frac{9}{1,000}

In a number line

-\frac{1,000}{1,000} < -\frac{9}{1,000}

Remember that

-\frac{1,000}{1,000}=-1\\\frac{0}{1,000}=0

so

-1 < -\frac{9}{1,000}

therefore

The two integers closest to -0.009 are -1 and 0
