Answer:
5(25 + z)
Step-by-step explanation:
(100+4z)20 can be reduced, since 4 divides evenly into 100, 4 and 20:
(25 + z)(5), or 5(25 + z).
This result can be left as is, or rewritten as 125 + 5z.
Answer:
0.5
Step-by-step explanation:
From the given data, to find out the probability of the train being late we employ the following method:
Probability of train being late = how many times the train was late / total train trips
Probability of train being late = 5 / 10 = 0.5
Since this is the probability of the train being late, the probability of it being on time will be 1 - (prob. of train being late)
This is:
Probability of train being on time = 1 - 0.5 = 0.5
Answer:
multiply one or both of the equations until a variable can cancel out
Answer:
about 15.6cm.
Step-by-step explanation:
I got my answer of 15.6cm because I did the Pythagorean theorem.
a^2+b^2=c^2
The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.
Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.
In conclusion, the measure of the other leg is about 15.6cm.
