Answer:

<em></em>(x,y) = (5,15)<em></em>

<em></em>

Step-by-step explanation:

Given

Nickels = x

Pennies = y

Minimum of 20 coins means:

x + y \ge 20

A nickel worth $0.05

A penny worth $0.01

So, the worth can be represented as:

0.05x + 0.01y \le 0.40

<em>See attachment for graph</em>

<em></em>

From the attachment, the solution is:

<em></em>(x,y) = (5,15)<em></em>

the area of a rectangular photograph is 35 square inches. If the width of the photo is 5 inches how tall is the photo
Vika [28.1K]
We know that:

Area= length*width

Plug in the stuff you know.

35= length(tall)*5

Divide both sides by 5.

7= length

The photo is 7 inches tall.

I hope this helps!

What is the area of Georgia rounded to the nearest square mile, The is square mile as 59,424.77?
bazaltina [42]

Answer:

59,425 sq mi

Step-by-step explanation:

When you want to round to the units place, you look at the digit in the number that is in the place to the right of that: the tenths place. Here, that digit is 7, which is more than 4. Because that digit is more than 4, 1 is added to the units place and all the digits to the right of that are dropped.

This gives you 59,424 +1 = 59,425.

_____

If the tenths digit were 4 or less, no change would be made to values in the units place or to the left of that. The tenths digit and digits to the right would be dropped.

... 59,424.3 ⇒ 59,424 . . . . . for example
