Area of circle is πr^2
<u>Here</u>,
• π = 3.14
• d = 10
• so, r = d/2 = 10/2 = 5
<u>substituting the values in the formula,</u>
Area = 3.14 x 5 x 5
Area = 3.14 x 25
Area = 78.5 m^2
Hence, option (c) is correct.
Answer:
S= z (y-x)/(x+y)
Step-by-step explanation:
Lets the speed of high speed train = u
Lets the regular speed train = v
We know that
Distance = Speed x time
For high speed train
z = u .x
u= z/x ----------1
For regular speed train
z = v .y
v = z/y -------------2
Both are traveling in opposite direction so relative speed
Vr = z / x+ z /y
Lets in time t they will meet
z = (z / x+ z /y) t
t= xy/ (x+y)
Lets take distance cover by high speed train is m when it moves A to B and speed cover by regular train is n when it is moving B to A.They meet at time t.
m = u .t
m = z / x .xy/ (x+y)
m = zy/ (x+y) -----------3
n = v .t
n = z / y .xy/ (x+y)
n = zx/ (x+y) -----------4
From equation 3 and 4
So
m - n= zy/ (x+y) - zx/ (x+y)
S= z (y-x)/(x+y)
Option a is correct.
Answer:
21f
Step-by-step explanation:
5f+16f
(5+16)f
21f
Answer:
5/2
Step-by-step explanation:
<u>Rise</u> = <u>5</u>
Run 2
Now, with that, our y intercept is -6 because the line hits the y axis at -6 units. Then, we can setup our own equation for y=
and that is y=5/2 x -6
Then I have attached a graph below to certify my answer.
