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.
first divide 90 by 4 to see how many words per minute
90 ÷ 4 = 22.5
then multiply 22.5 by 10 to get your answer
so your answer is;
225 words per 10 minutes
Answer:
56%
Step-by-step explanation:
Step-by-step explanation:
x=180°-109°=71° (Interior angles)
y= 71° (Alternate angles)
y= 180°- 65°=115° (Adjacent angles)
x= 65° (Corresponding angles)
So electricity costs 15cents every 1,000 watts used, and if he watches tv for 2hrs every day for a month that’s 60 hours (2*30) And every hour he watches tv it’s 150 watts. They want you to do the 60 hrs times 150watts which is 9,000 (amount of watts he uses in the month) and remember 1,000 watts is 15cents
