Answer: 12 men would be needed to repair the same road in 3 1/3 hrs. Inverse proportion because usually in work,food and time its inversly proportional.
8 hours --> 5 men
1 hour --> 5*8 = 40 men
3 1/3 hours --> 40/ (3 1/3) men
--> 12 men
Answer:
y = 3x - 10
Step-by-step explanation:
Step 1: Rewrite 1st equation
2y = 6x + 4
y = 3x + 4
Step 2: Find 2nd equation
y = 3x + b
-4 = 3(2) + b
-4 = 6 + b
b = -10
Step 3: Rewrite 2nd equation
y = 3x - 10
And we have your parallel equation!
36/54=2/3
36/24=2/3
so each time it bounches 2/3 or what it bounced before
seems to be a geometric sequence
an=a1r^(n-1)
a1=first term
r=common ratio
a1=54
common ratio is 2/3
an=54(2/3)^(n-1)
Answer:
The correct option is A.
Step-by-step explanation:
Braxton is testing 2 different types of motor oil in his truck to determine which one will last longer.
Now, he adds Brand A to the truck and Brand B to his sister's car.
Now, as Braxton wants to test the motor oil in his truck so there is no need of adding the motor oil to his sister's car as by doing so he cannot result in to a meaningful conclusion.
So, Braxton need to add both the motor oil into his truck one by one.
Hence, The conclusion of Braxton is not valid because he added Brand B to his sister's car, not the truck.
Therefore, The correct option is A.
