Mr White can travel for 6 hours while taking 3 breaks of 10 minutes each. Once, he had to travel for 36 hours. How many minutes
alexgriva [62]

180 min

Explanation:

3 × 10 min = 30 min

In 6 hours, Mr. White takes a total of  30 min  in breaks.

36 h = 6 h × 6  

In  36 hours , there are  6  sets of  6 h .

Hence we can multiply the number of minutes in breaks taken in  

6 h ours by  6  to obtain the number of minutes in breaks taken in  36 h ours.  

30 min × 6 = 180 min

How can you tell if a point is a solution to a system of equations?
Anna35 [415]

Answer: you have to substitute them into the equation

Step-by-step explanation:

example: x = 2y - 6

lets say you test 4/5 so it would be 4 = 2(5) - 6

this equals 4 = 10 - 6 which is true

so that is how you test to see if the equation is right

remember the first number goes to "x" and the second one goes to y

hope this helps mark me brainliest if you can

If the null hypothesis of an experiment is “The true mean weight of the geese is greater than 40 pounds” what is the alternate h
Ira Lisetskai [31]

Answer:

<em>"The true mean weight of the geese is less than or equal to 40 pounds"</em>

<em></em>

Step-by-step explanation:

<u>Something (or some value) can be either equal to, greater than, or less than another thing (another value).</u>

Null Hypothesis is what is given and Alternate is what we are testing.

Since Null Hypothesis is given that the mean weight is GREATER THAN 40 pounds, the ALTERNATE HYPOTHESIS would be the mean weight is either EQUAL TO or LESS THAN 40 pounds.

Thus, alternate hypothesis is <em>"The true mean weight of the geese is less than or equal to 40 pounds"</em>
