Step-by-step explanation:
the length of unknown side =
√18²-(33-25)² =
√18²-8²= √324-64
=√260 = 16.1 ft
the perimeter= 16.1 +33+18+25
= 92.1 ft
Answer: 3. Distributive
Step-by-step explanation:
3(x -2y) = 3x - 6y To get from left to rigth, you have to multiply them which is the same as distribitue.
3(x) - 3(2y) = 3x - 6y
Answer:
If your solving by sub. then it would come out as
a=-2
b=1
c=-2

Answer:
Step-by-step explanation:
This is a probability event that expresses the likelihood of an event to occur.
Number of paper clips in sack = 3
Number of erasers in sack = 5
Problem: Probability that one will draw a paper clip and then an eraser?
These are two mutually exclusive events.
Total number of paper in sack = 3 + 5 = 8
Pr(drawing paper clip) =
without replacement suggests that the total number of paper in sack will reduce by 1 to 7;
Pr(drawing eraser) =
So:
Pr(paper clip and eraser ) = =
Answer:
See below
Step-by-step explanation:
Do a factor tree for sevens....
7, 14, 21, 28, 35, 42, 49
Then, for the price price start at 32 and add 3 for every crossingthe first crossing is the pass price plus the fee.
35, 38,41, 44, 47, 50
So the driver can cross five times for $35, or just once for the discount pass. However, the pass would be cheaper in the long run. By the 11th crossing the regular fee would be up to$77, while the discount would be $65.
