Answer:
The volume of cylinder is V=πr^2h
Answer:
$60
Step-by-step explanation:
The savings of Andries is $120 and his grandfather offered that he would give 50% of the amount he saved.
50% is actually just half of a given amount. So the short way to do this is just half the saving of Andries.
![\dfrac{\$120}{2} = \$60](https://tex.z-dn.net/?f=%5Cdfrac%7B%5C%24120%7D%7B2%7D%20%3D%20%5C%2460)
You can also think of it this way:
![50\%=\dfrac{50}{100}](https://tex.z-dn.net/?f=50%5C%25%3D%5Cdfrac%7B50%7D%7B100%7D)
So we multiply that to the amount saved to solve for what is 50% of 120.
![\$120\times\dfrac{50}{100} = \dfrac{\$6000}{100}=\$60.00](https://tex.z-dn.net/?f=%5C%24120%5Ctimes%5Cdfrac%7B50%7D%7B100%7D%20%3D%20%5Cdfrac%7B%5C%246000%7D%7B100%7D%3D%5C%2460.00)
Your answer would be -13 !!!
Answer:
Luis traveled 11.82 km in total.
Step-by-step explanation:
<em>The statement should say</em>: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?
Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):
![d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km](https://tex.z-dn.net/?f=%20d%20%3D%20d_%7Bt%7D%20%2B%20d_%7Bc%7D%20%3D%206.37%20km%20%2B%205.45%20km%20%3D%2011.82%20km%20)
Therefore, Luis traveled 11.82 km in total.
I hope it helps you!
