Area=length * width
area= 9.87 * 1.09
The answer is 10.7583m and if you round it it is 10.8m.
Answer:
let cp be x
sp= 115x/100 ---(when 15%gain)
sp = 88x/100------(when 12% loss
according to question
115x/100 - 88x/100 = 81
or, (115x-88x)= 8100
or, 27x = 8100
or, x= 8100/27
x = 300
hence cp is RS 300
Expand the EXPRESSION
9x^2+216x+1296
Answer: 3/4 is 0.0075.
3/25 is 0.0012
Step-by-step explanation:
When you convert 3/4 into a decimal it is 0.75% but to change that into a decimal you have to move the decimal 2 place values and then 0.75% become 0.0075. The same happens for 3/25. 3 divided by 25 is 0.12% but when you move it 2 place values to the left then it becomes 0.0012.
Answer:
x = 36.87 degrees.
Step-by-step explanation:
4 cos x + 3 sin x = 5
Use the Auxiliary angle method:
R sin (α + x) = R sin α cos x + R cos α sin x
Comparing coefficients:
R sin α = 4 and R cos α = 3
R sin α / R cos α = 4/3
So tan α = 4/3
α = 53,13 degrees.
Now R^2(sin^2 α + cos^2 α ) = 3^2 + 4^2 = 25
R^2 = 25
R = 5.
R sin (x + 53.13) = 5
5 sin ( x + 53.13) = 5
sin (x + 53.13) = 1
x + 53.13 = 90
x = 36.87 degrees.
