Answer:
D) 11/3
Step-by-step explanation:
Let x represent monthly salary.
We have been given that for each month of a given year except December, a worker earned the same monthly salary and donated one-tenth of that salary to charity.
Salary earned in 11 months would be 
.
Money donated in 11 months would be 
.
Further we are told that in December, the worker earned N times his usual monthly salary and donated one-fifth of his earnings to charity.
Salary for December would be 
.
Money donated in December would be 
.
The worker's charitable contributions totaled one-eighth of his earnings for the entire year that is 
.
Dividing whole equation by x, we will get:
Combine like terms:
Therefore, the value of N is 11/3 and option D is the correct choice.
Answer:
B)
Step-by-step explanation:
If you try to divide 135 with each number,every number is divisible by 135 XD
Answer:
Step-by-step explanation:
Since all the answers are 100s I assume the sizes are 10, 10 and 20.
This would mean there are 2 sides of 10x10 and 4 of 10x20
The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800
Area of rectangle is given by:
Area=length*width
let the length be l
the width width will be:
w=192/w
but Pythagorean theorem is given by:
c^2=a^2+b^2
thus plugging in the values we get:
20²=w²+(192/w)^2
400=w²+36864/w²
solving the above we get:
w=-16, w=-12, w=12, w=16
thus the dimensions are 12 inches by 16 inches
