Answer 2
Answer: Since there are 5 volumes to rearrange and the way to find the number of combinations to rearrange objects is by multiplying numbers that you count down from the original number (5 in this case) to 1, the problem is set up as 5×4×3×2×1.
Now solve!
5×4×3×2×1
20×3×2×1
60×2×1
120×1
120
120 ways to rearrange the volumes.

A merchant bought 30 dozen pairs of gloves. How many individual gloves did the merchant buy? A-720 B-420 C-300

Answers

The merchant product bought a total of 360 individual gloves is C-300.

To find the total number of individual gloves the merchant bought, we need to calculate the product of the number of dozen pairs and the number of gloves in each pair.

30 dozen pairs of gloves mean 30 x 12 pairs of gloves since there are 12 pairs in a dozen.

Now, to find the total number of individual gloves, we multiply the number of dozen pairs by the number of gloves in each pair:

30 dozen pairs x 12 gloves per dozen pair = 360 gloves

30x12x2

There are 30 dozen, a dozen means twelve. 30 times 12 is 360. There are 360 pairs of gloves. A pair means 2. 360 pairs times 2 gloves in a pair equals 720.

If a ferris wheel diameter is 250 ft. Find it's cirumference. Give an exact answer and an approximation using 3.14 for pi how do I come up with this answer I keep trying but cant figure it out

Answers


The circumference of ANY circle is (pi) times (diameter).  Doesn't matter
if it's one tiny link in the silver chain of a necklace or the circular orbit of
a planet. 

             Circumference = (pi) times (diameter) .

Please memorize that.  In high school, you should already have it memorized.

The diameter of the ferris wheel is 250-ft.

   Exact answer:     Circumference = 250 pi feet

You can't write the exact answer completely in numbers,
because you can't write 'pi' completely in numbers.

   Approximation using pi = 3.14 :

                             Circumference = (250) x (3.14) = 785 feet
Circumference = πd
C= 250(3.14)
C=785

Over twenty years, it was found that the number of doctors of medicine, MD (in thousands), in the United States can be approximated by MD=(28,390+693t)/(85-t) where t=0 represents 1980. The number of doctors of osteopathy, DO (in thousands), can be approximated by DO=(776-12t)/(65-2t) .Write an expression for the total number I of doctors of medicine (MD) and doctors of osteopathy (DO). Simplify the result.

How many MDs did the United States have in 2010? How many MDs did the United States have in 2010?

Answers

The expression for the total number of doctors is (-1374t^2+43192.22t+67805.35)/((65-2t)(85-t) )

We have to write an expression for the number of MD and DO

a. MD + DO

(28390+693t)/(85-t) +(776-12t)/(65-2t)

This can be simplified as

((28390+693t)(65-2t)+(776-12t)(85-t) )/((85-t)(65-2t) )

= (-1374t^2+43192.22t+67805.35)/((65-2t)(85-t) )

b. If t = 0 in 1980, in 2010, t = 30

The number of MD would be

(28390+693*30)/(85-30) \n= 379

The number of DO would be

(776-12*30)/(65-2*30)\n\n= 83
