We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc. For this type of problem you use the "n choose k" formula...
n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..
In this case:
20!/(10!(20-10)!)
20!/(10!*10!)
184756
For this case, the first thing to do is find the scale factor.
Using the measure of height we have:
k = (360) / (18 * (1/12))
k = 240
Thus, the length of the building is:
(14 * (1/12)) * (240) = 280 feet
Answer:
The lenght of the real building is:
280 feet
The base price of the car is about $22,196 because:
x= major options package
10x + x = 24,416
*the 10x is the price of the car
This then simplifies to
11x = 24,416
use division.
The destination charge is not needed unless you want to check your answer. If you have to then you would do the same thing. The equation would be:
y= destination charge
5y + y = 24,416
Hope this helps.
Answer:
13/14
Step-by-step explanation:
3/7+1/2
LCM = 14
6/14+7/14=13/14
Y = -2x - 7
slope = -2 (parallel shares the same slope, -2)
Option A:
y = -2x + 7
slope = -2
At (3, 1)
y = -2(3) + 7 = 1
Answer: Option A
