Answer:
B) 5 hours
Step-by-step explanation:
First, find the amount of mph between 60 and 80:
80 - 60
= 20 mph
Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:
20/4
= 5
So, the correct answer is B, 5 hours
Remember that the cone volume formula is
, with r = radius and h = height. Using our information, we can form our equation as such:
(I'll be keeping the answer in pi form.)
Firstly, solve the exponents:
Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
Answer:
In 16170 ways the committee can be formed.
Step-by-step explanation:
3 faculty members and 5 students are required to form a committee.
The eligible to serve on the committee are 7 faculty members and 11 students.
If each committee position has the same duties and voting rights.
Then, the number of ways of selecting 3 faculty members out of 7 eligible faculty members is
.
Again, the number of ways of selecting 5 students out of 11 eligible students is given by
.
Therefore, in (35 × 462) = 16170 ways the committee can be formed. (Answer)

Answer:
B. 100
Step-by-step explanation:

143-13=130
10x=130 divide both sides by 10 130/10= 13 x=13
MN=7(13)=91+9=100
LN=3(13)=39+4=43
100+43
