Sean answered 18 of 20 quiz questions correctly. what percent of the quiz questions did sean answer correctly? a 11% b 18% c 90% d 98%

C. 90% this is found by
20*0.90 or 90%=18
so 90% would be correct.
hope this helps!

It is indeed C but to find it you need to divide the number of answers he got correctly by the total number of answer.
So, it's 18 divide by 20, which would give you 0.90
Once you get the decimal, you multiply it by 100 to get the percentage, which is 90%.
I hope this helps.
YOU'RE WELCOME :D

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

What the heck don’t understand
