The question is incomplete as the total number I crosswords required for completion isn't given :
Hypothetically, if the total Number of cross words is taken as x ;
Answer:
2 /x
Step-by-step explanation:
The number of crosswords John did = 1 + 1 = 2
Total number of cross words = x
Fraction of crosswords John did :
2 / total number of crosswords
2 / x
Kindly substitute the actual number of crosswords for X to obtain exact answer.
Answer:
The area is changing by the rate of 44.62 meters per sec.
Step-by-step explanation:
Let x be the side of the square and r be the radius of the circle,
Then, the area outside the circle but inside the square is,
V = Area of square - area of circle,
∵ Area of a square = side² and area of a circle = (radius)²,
Thus,
Differentiating with respect to t ( time )
We have,
x = 20 meters, r = 3 meters,
Answer:
<h2>22ft</h2>
Step-by-step explanation:
Step one:
given that the orientation of the garden is a triangular shape(it has three sides)
the perimeter is given as=46ft
one side y=11ft
the second side z= 13ft
let the third side be xft
Step two:
the expression for the perimeter = z+y+x
46=11+13+x
46=24+x
solve for x
x=46-24
x=22ft
Therefore the third side is 22ft long
Answer:
b = 17.55
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + b^2 = 18^2
16 + b^2 = 324
<u>-16 -16</u>
b^2 = 308
square root them
<u>b = 17.55</u>
let me know if it is correct!
0.3r/0.3=2.1/0.3
r=2.1/0.3
r=7
