60% of 20 is (0.6 x 20) = 12 passes
There are a further 30 quizzes remaining (50 total during the year minus 20 already written)
80% of 30 is (0.8 x 30) = 24 passes
The student has passed (12 + 24) = 36 quizzes out of 50 total, giving an overall pass percentage of ((36 / 50) x 100)) = 72%.
Answer:
L - W = 2 and 2L + 2W = 68
Step-by-step explanation:
The two equations here are going to be-
Length minus width equals 2
L - W = 2
And
Length x 2 + Width x 2 = 68
2L + 2W = 68
Answer:
A
Step-by-step explanation:
So that is a 90 degree angle and there is an angle of 30. 30-90 is 60. 60 divided by 4 is 15. So thus the answer is A,15.
4( 40 - 30)
subtract 30 from 40 is expressed as 40 - 30
then multiply by 4 is expressed as 4 × (40 - 30) or 4(40 - 30) = 40
