Phoenix [80]
Since the length is 15, and the width would be 15, you need to first do 15 x 15.

15 x 15 = 225


Multiply the 6 faces.

The radius of a circle is 3.9 in. Find the circumference to the nearest tenth.
masha68 [24]

Answer:

C = 24.5 in

Step-by-step explanation:

Formula to find the circumference of a circle is :

C = 2πr

Here,

r ⇒ radius

So let us solve now.

C = 2πr

C = 2 × π × r

C = 2 × 3.14 × 3.9

C = 24.492 in

So, they've asked for nearest 10th.

Therefore, the answer will be 24.5 in.

Hope this helps you :-)

Let me know if you have any other questions :-)

Suppose a certain religious university has a ratio of approximately 90 males to 125 females enrolled as a students. If he curren
Nitella [24]
How many males and how many females would there be if the total enrollment is 15000?

Ratio is 

  90 males      15000 - x
  ------------- = ---------------
   125 fem              x

Then 90x = 1875000 - 125x, or 215x = 1875000

                                                      x = approx 8720 females
                       and 15000-8720, or 6279 males

If every male finds a dance partner, that would leave (8720-6279) females, or 2440, without dance partners.  ;(

Check:  is the male:female ratio near 90:125?

Is 6279:8720 approx equal to 90:125?

Yes.  0.72 (approx) = 0.72 (approx).

To paint a house, a painting company charges a flat rate of $500 for supplies plus $50 for each hour of labor. What is the slope
Nataly_w [17]
The slope of the line is 50. You can try looking at the equation, which is

y=50x+500

500 is your y-intercept, and is where the cost starts.

50 is your slope, since the cost goes up by $50 every time.

x is how many hours, which determines how many $50s there are.

I hope this helps. All in all, the slope is 50.
