When jonas does his math homework, he spends an average of 4 minutes on each problem. last night he spent 1.8 hours on his non-math homework, plus he completed 12 math problems. approximately how much time did jonas spend in total on all of his homework last night?

2.6 hours.

Step-by-step explanation:

That would be 1.8 hours plus 4 * 12 = 48 minutes.

48 minutes = 48/60 = 0.8 hours.

Total is 1.8 + 0.8 = 2.6 hours.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
