a math teacher wants to make a test containing 50 easy questions and 20 hard questions. each easy question is allowed 30
seconds and each hard question is allowed 1 minute 30 seconds to complete. how many minutes should the teacher allow for the
whole test?

Maximum time the teacher should allow for the whole test should be = 55 minutes

Step-by-step explanation:

Number of easy questions in the test = 50

Number of hard questions in the test = 20

Time for each easy question = 30 seconds =    

[As 1 minute = 60 seconds]

Time for each hard question = 1 minute 30 seconds =

Using unitary method to find duration of whole test.

If 1 easy question takes = 0.5 minutes

Then, 50 easy questions will take = = 25 minutes

If 1 hard question takes = 1.5 minutes

Then, 20 hard questions will take = = 30 minutes

Total time for the test will be = = 55 minutes

Hello, User!

to find the volume of a cone you need to use this equation!

were r= radius and h=height

then we substitute the values into the equation!

Therefore your answer is about 47 in!

I hope I helped and I was super exited and honored to answer your question have a very nice day!

but if you dont do pi

you get..

so its B. 15(pie) in ^3
