To visit his grandmother, Luis takes a train 6.376.376, point, 37 kilometers and a car 5.455.455, point, 45 kilometers.
murzikaleks [220]

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

Therefore, Luis traveled 11.82 km in total.

I hope it helps you!

Can someone help me with this question. I'll give brainliest answer to whoever helps me.
enot [183]

Answer:

The answer is 2root5 or C

Step-by-step explanation:

The square root of 20 is 4.472135... so, you have to solve what of your possible solutions could be the right answer (it's best to use a graphing calculator). We already know it not A, so that's off the list because the square root of 20 is already greater than 4. We then move onto C or 2root5 which we also get 4.472135... (by doing 2 * the square root of 5). We then move onto B and find that 5root2 is 7.07 (by multiplying 5 by the square root of 2). So B is off the plate. Lastly, is 20 = to the square root of 20. No, we already established that in the beginning of the problem. So, overall the answer is C or 2root5.

D

Step-by-step explanation:

y and 70° are same- side interior angles and sum to 180° , that is

y +70° = 180° ( subtract 70° from both sides )

y = 110° → D
