Answer:

jim is 24 years old,  Mark is 20 years old

Step-by-step explanation:

This prompt can be set up using this equation:

Let's represent Mark's age by variable m and Jim's age by variable J.

j + m = 44

m + 4 = j

m = j - 4

j + (j - 4) = 44

2j - 4 = 44

2j = 48

j = 24

So, jim is 24 years old, meaning mark must be 20 years old. 20 + 24 results in 44 years old together.

An artist used silver wire to make a square that has a perimeter of 40 inches. She then used copper wire to make the largest cir
finlep [7]

Answer:

The area of the copper circle is <u>31.4 inches</u>.

Step-by-step explanation:

Given:

An artist used silver wire to make a square that has a perimeter of 40 inches.

She then used copper wire to make the largest circle that could fit in the square, with perimeter of 40 inches.

Use 3.14 to represent π.

Now, to find the area of the copper circle.

Perimeter of square = 40 inches.

So, we get the side of square by putting formula:

Perimeter=4\times side

40=4\times side

Dividing both sides by 4 we get:

10=side.

Side=10\ inches.

Now, as the side of square is 10 inches it is the diameter of the circle as the square is fit inside the circle:

For getting the area of circle we find the radius:

Radius (r) = \frac{Diameter}{2} \\=\frac{10}{2}= 5\ inches.

Now, putting the formula to get the area of the circle:

Area=2\times \pi \times r

Area=2\times 3.14\times 5

Area=31.4\ inches.

Therefore, the area of the copper circle is 31.4 inches.
