We assume that the problem above involves right triangles, wherein the diameter of the moon would be the height and the distance from Earth would be the base. By finding the desired angle, we used the tangent function:
tan (theta) = 2160 / 238860
theta = tan -1 *( 2160 / 238860) = 0.516 degrees
Therefore the angle in the eye of the beholder would be half a degree.
Answer:
The speed of the boat in still water u = 8
Step-by-step explanation:
Let speed of the boat = u
Speed of the current = v = 4
Given that the first boat to travel 3 miles upstream and back in a total 1 hour.
So
Since v = 4
By solving above equation
u = 8 , - 2
Since u = -2 is not valid.
⇒ u = 8
This is the speed of the boat in still water.

Answer:
Solution is not correct.
Step-by-step explanation:
Given question is incomplete; Here is the complete question.
Is the solution shown in the attachment correct ?
9x + 2 = 8x² + 6x
We have to solve this equation with the help of quadratic formula,
-8x² + 9x + 2 = 6x
-8x² + 9x - 6x + 2 = 0
-8x² + 3x + 2 = 0
Quadratic formula of a standard quadratic equation (ax² + bx + c = 0) is,
x =
By comparing our equation with the standard quadratic equation,
a = -8
b = 3
c = 2
By substituting the values of a, b and c in the quadratic formula,
x =
x =
x =
Therefore, the given solution is not correct.
Answer:
The amount of D's there were is 275.4
Step-by-step explanation:
D : A
6 : 19
D : 872
Cross multiply 872 and 6
6*872 = 5232
Then divide the total by 19
5232/19 = 275.4 (simplified)
