X+4>-15
x>-15-4
So x>-19
so the value of xis greater than -19
3/4 or .75 hope this helps!!
Answer:
Hence it will take 35hours
Step-by-step explanation:
Let the time it took to dig hole be x
Ley the number of holes be n
Using the relationship x = kn (direct relationship)
if it takes 3 men 5 hours to dig 12 holes, hence;
when x = 5, n = 12
k = x/n
k = 5/12
To get how many hours it take for 3 men to dig 84 holes, then;
when n = 84, x = ?
x = 5/12 * 84
x = 5 * 7
x = 35hours
Hence it will take 35hours
The answer to the question is C
Answer:
d. (16/24) * 100%
Step-by-step explanation:
The infection rate =( Number of infected people/ total number of people) * 100%
After the end of round 3
Infection rate = (8/24)*100%
After the end of round 4, since no one is infected more than once
Infection rate = 2* (8/24)*100%
Infection rate = (16/24) * 100%
