Answer:
161700 ways.
Step-by-step explanation:
The order in which the transistors are chosen is not important. This means that we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this question:
3 transistors from a set of 100. So

So 161700 ways.
The second option. The 5.5w part shows that its $5.50 times each window. The -3.25 is because he deducted 3.25 from the total. And then you have the price that he got on the other side.
Here's the work to find the windows in case you want it:
5.5w-3.25=35.25
5.5w=38.50
w=7
He washed 7 windows

Answer:
w = 160, L = 50
Step-by-step explanation:
Length = 50 feet
Width = 160 feet
First Find the Length
w = l + 110
P=2w+2l
420=2w+2l
420=2(l+110)+2l
420=2l+220+2l
4l=200
l=50
Finding the Width
w=(50)+110
w=160
