Answer:
Step-by-step explanation:
The radius of the circle is 35 cm
Step-by-step explanation:
One revolution of the wheel of a cart = the length of the circumference of the wheel
Let the radius of the wheel be r cm
The circumference = 2 X pi X r
In 5000 revolutions the wheel covers 2 X pi X r X 5000 cm
According to the problem,
2 X pi X r X 5000 = 11 X 1000 X 100
or, pi X r = (11 X 1000 X 100)/(2 X 5000)
or, r = 110 / pi
or, r = (110 X 7)/22
= 35
Here is the answer.
Answer:
y+21 = -4(x-7)
Step-by-step explanation:
well first you need to find slope what is y2-y1 over x2-x1
23-(-21) ----> 23+21 = 44
-4 - 7 ---> -4 + -7 = -11
so it 44/-11 = -4 is the slope
now choose one pair of points like 7 , -21 and plug them in
y-y1 = m(slope)(x-x1)
so it be y+21 = -4(x-7)
also remember two negatives = a postitive
Angle DFB = (1/2)*[(arc CE)+(arc BD)]
Angle DFB = (1/2)*(84+38)
Angle DFB = (1/2)*122
Angle DFB = 61
(Angle DFB) + (angle DFE) = 180
angle DFE = 180 - (Angle DFB)
angle DFE = 180 - 61
angle DFE = 119 degrees

Final Answer is choice D) 119 degrees
Answer:
Rs. 4.2
Step-by-step explanation:
10 kg of apples cost Rs. 42
1 kg of apples cost Rs. 42 / 10 = Rs. 4.2
