Answer:
7/4 +1/6 +X=15/2
1/6+X=15/2-7/4
1/6+X=30/4-7/4
X=23/4 - 1/6
X= 138-4/24
134/24
5.58333
Step-by-step explanation:
Answer:
x=16
Step-by-step explanation:
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x
S.P. of x articles = Rs. 20
Profit = Rs. (20 - x)
∴20−xx×100=25
⇒ 2000−100x=25x
125x=2000
⇒ x=16
Answer:
radius: 4√(2π)/π "four times the square-root of two pi, over pi"
Step-by-step explanation:
The formula for area of a circle is
A = πr², where A is the area, π is the constant value pi, and r is the radius
We are given an area of 32 m² and need to find the radius, so we have...
32 = πr²
First, divide by π to get the r term by itself
32/π = r²
Now take the square root of both sides...
√(32/π) = r
Simplify the left side, you can distribute the square root to the numerator and the denominator...
(√32)/(√π) = r
√32 breaks down into 4√2 using a factor tree. You can't have a square root in the denominator so multiply top and bottom by √π
[(4√2)(√π)]/[(√π)(√π)] = r
This simplifies to
4√(2π)/π
