Answer:
P=1/42.
Step-by-step explanation:
We know that the student council has 10 members where 5 of the members are Seniors. They need to choose a President, Vice President, Secretary and Treasurer. We calculate the probability that the President is a Senior:
We calculate the number of possible combinations:

Number of favorable combinations is 5.
Threfore, the probability is
P=5/210
P=1/42.
Let the value of the vertical drop be x
cos20°=x/11
x=0.9*11
x=9.9
Thus, the length of the vertical drop is 9.9 feet
Answer: root of 18
9+9=x^2
18=x^2
x = 3 root of 2 or root of 18
the difference from 240 to 120 is 50%
Answer:
343 can be written as

Step-by-step explanation:
since we know,
343 = 7 × 7 × 7
so, we can write 343 as cube of 7
hence,
