Answer:D) 1 hr
Step-by-step explanation:
Given
Pump A and B can fill tank in 
Pump A and C can fill tank in 
Pump B and C can fill tank in 
Let A be the total hr taken A therefore rate of 
Let B be the total hr taken B therefore rate of 
Let C be the total hr taken C therefore rate of 
-----1
-----2
-----3
Adding 1,2 & 3



thus time taken by A,B and C combined is 1 hr
Solve the equation for y
x-3y= -18
-3y = -18-x
now, divide both sides with -3
y = (-18-x)/-3
y = 6 +x/3
your slope is 1/3
and y-intercept is 6

Answer:
No.
Step-by-step explanation:
Let's find out if 1 bag of soil is enough to fill 1 container.
<u>Given:</u>
2/5 of a bag fills 1/3s of a containter.
With the given, multiplying 2/5 by 2.5 represents one. Multiply 1/3 by 2.5 aswell.
<u>Products:</u>
1, and 2.5/3 or 5/6
1 bag can fill 5/6 of a container.
Therefore, 1 bag can't fill 1 container.
Answer:
part a
The probability of getting a 2 is 1/6 and the probability of getting a head is 1/2. The probability of getting both is thus 1/6 x 1/2= 1/12
part b
The probability of getting an even number is 3/6 = 1/2. The probability of getting a tail is 1/2. The probability of getting both is thus 1/2 x 1/2= 1/4.
