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):

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

Therefore, the time it takes them to paint the fence together is 30/11 Hours

To paint a sunset , Tran makes a shade of orange paint using 5 drops of red paint for every 8 drops of yellow paint

lora16 [44]

So we multiplied the red paint by three because 5 times 3 is fifteen so we have to multiply 8 by 3 as well. The answer is 24 drops of yellow paint. I hope this helps and have wonderful day!! :)

3/4 = c/36 I need help with this fraction proble.

Nataliya [291]

Answer:

c = 27

Step-by-step explanation:

given $\frac{3}{4}$ = $\frac{c}{36}$ ( cross- multiply )

4c = 3 × 36 = 108 ( divide both sides by 4 )

c = 27

note that $\frac{27}{36}$ = $\frac{3}{4}$ in simplest form

The surface area of the world is about 7/10 water. If a very small, non-dangerous meteoroid lands on the earth, what is the prob

galben [10]

Answer: 3/10 probability

Step-by-step explanation:

We are telling the probability with tenths, so we can say that the probability of the meteoroid landing on Earth is 3/10.

If the surface area of the world is approximately 7/10, or 70 percent, water, there is approximately 3/10, or 30 percent, chance of the meteoroid hitting land.

I'm pretty sure, at least ^_^
