Answer:

8 1/6

Step-by-step explanation:

5/6 + 7 1/3

Change the fractions to different denominators.

5/6 x 1/1 = 5/6

1/3 x 2/2 = 2/6

5/6 + 2/6 = 7/6

7/6 = 1 1/6

1 1/6 + 7 = 8 1/6

In a tank of water, a can of regular soda will sink to the bottom, but can a diet soda of diet soda of the same size will float

Anastasy [175]

Answer:

One of the many reasons of this is because the diet soda is less dense than the normal soda, therefor, it will float even though there's the same amount of liquid in each can, and the cans weigh the same amount

7.33. Tom can paint Mr. Thatcher's fence in 6 hours, while Huck can paint Mr. Thatcher's fence in 5 hours. If they work together

Alik [6]

Answer:

It takes them 30/11 hours to paint them together.

Step-by-step explanation:

This is known as a work problem (rate * time = work). We are given the individual times for Tom and Huck (6 hours and 5 hours respectively). However, we are not given the rates at which they can paint the fence. Since we know that the total work that they both do individually is 1 (there is 1 job to do), we can calculate the rates at which Tom and Huck paint the fence on their own:

$Tom: R_{T}*6=1\\Huck: R_{H}*5=1$

We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:

$Tom: R_{T}=\frac{1}{6}\\Huck: R_{H}=\frac{1}{5}$

Now, we can calculate the time it takes for Tom and Huck to work together using the same formula (the combined rate is just the sum of Tom and Huck's individual rates):

$(\frac{1}{6} +\frac{1}{5})*T=1\\\\T*(11/30)=1 , T = 30/11$
