Use the distance formula to get the answer.
(-4-(-2))*2+(-2-2)*2
-2*2+4*2
4+16=20
Then you simply 20
=4.472135955
Factoring the numerator, we get 3(x-9). Factoring the denom., we get 3(x+1).
Simplifying
3(x-9) x-9
----------- we get --------
3(x+1) x+1
Answer:
650 calls
Step-by-step explanation:
so since you have 18$ per month plus 5 cents per call you would do
18+0.5n(n represent the number of calls)= the total fee of $50.50 cents.
thus,now you need to figure out how much the phone calls were without the monthly fee so you would do:
50.50-18=32.50
so 32.50 is the price of all the phone calls
then you divide 32.50 by 0.05 which equals to 650
meaning that n=650

Answer:
60% of the students passed the test
Step-by-step explanation:
total # of people taking the test: 36
# of people passed: 18
# of people failed: 36-18 = 18 (18 people failed the test)
percentage= (number of favorable outcomes/total number of outcomes)* 100%
(18/36)*100
= 60%
Answer:
378 people
Step-by-step explanation:
60% of 630 = 0.6 × 630 = 378
