Kalani has run 4 1/5 miles in 2/3 an hour. If he continues to run at this rate, how many miles will he run in one hour?

Mathematics

Blizzard [7]3 years ago

Answer:

Kalani will run 6.3 miles OR 6 3/10 miles.

Step-by-step explanation:

So first step that I would do is make it easier to understand by converting the fraction to a whole number. 2/3 hour= 40 minutes.

So Kalani runs 4 1/5 miles in 40 minutes.

Then, we convert 4 1/5 to 4.2. Next, I would divide 4.2 by 2 to get how long he ran in 20 minutes. 4.2/2=2.1.

The final step is to add 2.1 and 4.2 and we get 6.3.

Extra step:

But if we need to turn it back into a fraction, it would be 6 3/10

Hope this helps :)

serious [3.7K]

Answer:

200 packages

Step-by-step explanation:

change 6 m  to cm

100 cm = 1 m

6m  * 100 cm/1m = 600 cm

we have 600 cm

take 600 cm and divide by 3 cm to close each package

600 cm /3 cm = 200 packages

21 3/16...as a decimal
the 21 is a whole number and goes to the left of the decimal....and the fraction 3/16 goes to the right of the decimal.
3/16 = 0.1875....now add ur 21 and u get 21.1875 inches wide

2 3/8....as a decimal
3/8 = 0.375....now put ur 2 in there and it becomes 2.375 inches thick

If a 24-kg mass stretches a spring 15 cm, what mass will stretch the spring 10 cm
natulia [17]

Answer:

<h2>16kg</h2>

Step-by-step explanation:

 This problem is borers on elasticity of materials.

according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>

F= ke

where F is the applied force in N

          k is the spring constant N/m

          e is the extension in meters

Given data

mass m= 24kg

extensnion=15cm in meters= \frac{15}{100}= 0.15m

we can solve for the spring constant k

we also know that the force F = mg

assuming g=9.81m/s^{2}

therefore

24*9.81=k*0.15\\235.44=k*0.15\\k=\frac{235.44}{0.15} \\k=1569.6N/m\\

We can use this value of k to solve for the mass that will cause an extension of  10cm= 0.1m

x*9.81=1569.6*0.1\\\\x= \frac{156.96}{9.81} \\\x= 16kg
