So the way to determine is to find the density of your unknown metal. To do that, you know density is g/mL or g/cm3. So, you do 979/58. It is approximately 16.88 g/mL. So, the density is more than pure gold. (A)

I’m not 100% sure that mL = cm3 for this case so make sure you check that but that’s what I think the answer is!

Hello from MrBillDoesMath!

Answer:

9/2 > 3/2 (slope of <u>greater than.</u>..)

Discussion:

This seems like an odd question. We can say that

9/2 > 3/2

so the slope of the line with m = 9/2 is greater than (in fact, 3 times greater than) the slope of the line with slope m = 3/2

Thank you,

What is the area of a semicircle with a diameter of 14

Neporo4naja [7]

Answer:

76.9690 square units (rounded off to four decimal values)

Step-by-step explanation:

The diameter of the semicircle is 14 units

The radius of the semicircle is thus 14 ÷ 2 = 7 units

Area of a semicircle is given by: $\frac{1}{2}$ × π × r²

In our case, the area is = $\frac{1}{2}$ × π × 7² = 76.9690200129 square units

Or 76.9690 square units (rounded off to four decimal values)
