Answer:
$960
Step-by-step explanation:
take the total salary to be 100%, since the taxes are 20% subtract 20% from 100% to get 80% which will represent the left over after the taxes have been taken so say if 100%=$1200 what about 80% 80times 1200 then divide by 100.
Let x be the brick portion of the wall
Since x is 2/3 of the wall
Then x= (2/3)(2 3/4)
x= 11/6 = 1 5/6
So the brick portion of the wall is 1 5/6 feet
Note: that's not 15/6, it's a mixed fraction which is 1 + 5/6.. just to let you know

Answer:
1 student.
Step-by-step explanation:
No of students that like Reasoning = 129 - (85-54) - (89-54)
= 63
No of students that like Reasoning only = 63-54
= 9
No of students that like Calculus = 129 - (86-54) - (89-54)
= 62
No of students that like Calculus only = 62-54
= 8
No of students that like Algebra = 129 - (86-54) - (85-54)
= 66
No of students that like Algebra only = 66-54
= 12
No of students that like Algebra and Resoning only = (85-54)
= 31
No of students that like Algebra and Calculus only = (86-54)
= 32
No of students that like Reasoning and Calculus only =(89-54)
= 35
Total students = 182
Total students offering at least one module + total students offering none = Total students
182 = 9 + 8 + 12 + 31 + 32 + 35 + 54 + X
X = 182 - 181
= 1 student.
