Round 8,503 to nearest thousand
Jlenok [28]

Answer:

9,000

If x < 5, we round down.

If x ≥ 5, we round up.

Since 8,503, 500 is ≥ 5, we round up to 9. So,

Jocelyn was asked to draw a square with an area of 20 cm2. Which could be the side length of the square? I. 20 cm II. 5 cm III.
Paladinen [302]

Answer:

The correct option is III: 4.5 cm.

Step-by-step explanation:

The area of a square is the following:

A = b^{2}    (1)

Where:

A: is the area

b: is the side of the square

We have that the area is 20 cm², hence by solving equation (1) for <em>b</em> we can find the side:

b = \sqrt{A} = \sqrt{20 cm^{2}} = 4.5 cm

Therefore, the correct option is III: 4.5 cm.

I hope it helps you!
