The RideEm Bicycles factory can produce 170 bicycles in a day at a total cost of $10,900. It can produce 190 bicycles in a day a
KatRina [158]
If we assume that when producing 190 bicycles vs 170 bicycles the difference in total daily cost is purely attributed to the extra 20 bicycles, THEN the cost to produce 20 bicycles (190 - 170) = 11600 - 10900 = 700

So the cost per bicycle is 700/20 = 35/bike

Now we can subtract the cost of bicycle production to determine the daily fixed cost that is not related to the number of bicycles.

i.e. 170 bicycles x 35 = 5950

So on a day that RideEm produces 170 bicycles, subtract 5950 from total day cost of 10900, which equals 4950.

So the fixed daily costs are $4950, and on top of this, the company pays 35/bike to produce.

What is the length of AC ?<br><br> 3ft<br> 4ft<br> 9ft<br> 18ft
WINSTONCH [101]

ΔACB and ΔMNB are similar. Therefore the corresponding sides are in proportion:

\dfrac{AC}{MN}=\dfrac{CB}{NB}\\\\MN=9\ ft\\CB=2\cdot3\ ft=6\ ft\\NB=3\ ft

Substitute:

\dfrac{AC}{9}=\dfrac{6}{3}\\\\\dfrac{AC}{9}=2\ \ \ \ |\cdot9\\\\AC=18\ ft

What is the next number and why ? 1,3,11,35,99,_
Vladimir79 [104]

Answer: 241

Step-by-step explanation:

This is a simple problem when using Pascal's triangle. First you look at 1 - 3, what is the difference in these 2 numbers? Its 2, then you look at 3 and 11, the difference is 8, then 11 and 35, the difference is 24. If you keep doing this you get; 2 8 24 64 142. Next you find out how these numbers are different. In the end you keep doing this until you get to the triangles point or the differences converge.

                                          1      3      11      35     99      <u>241</u>

                                             2      8     24       64    142

                                                6      16      40      78

                                                     10     24      38

                                                          14       14

In the end we get 14 but there is no difference in the numbers so we cant go any farther. Hope this helps!
