Answer:
3 hours
Step-by-step explanation:
Given that:
Time taken by Kalon = 4 hours
Time taken by Marna =?
Time taken if the work together = 1 5/7 hours
Kalon's rate = 1/ time =. 1/4
Kalon + Marna = 1 ÷ 1 5/7 = 7/12
Hence,
Marna's rate = 7/12 - 1/4
Marna's Rate = (7 - 3) / 12 = 4/12 = 1/3
Marna's rate = 1/3
Hence, time it takes Marna = reciprocal of rate = 1÷ 1/3 = 1 * 3/1 = 3 hours
Answer:
3
Step-by-step explanation:
Mean= add up all the numbers, then divide by how many numbers there are. 0+3+6=9
9/3=3
Answer:
D) If an integer is NOT even then it is NOT divisible by 2.
Step-by-step explanation:
An inverse if/then statement is like an opposite statement. So the statement "if A happens, then B will happen" the opposite would be like saying "if A does NOT happen then B will NOT happen." Hopefully that makes sense :)
Answer:
Can you explain more?
Step-by-step explanation:
You can do prime factorization then find common factors to factor out.
6m² - 15m
2·3·m·m - 3·5·m
Both terms have 3·m so we can factor it out:
3·m (2·m - 5)
So that would be 3m (2m - 5)
