Answer:
They will be at a distance of 16 miles apart from each other.
Step-by-step explanation:
Both Joe and Anita start roller balding in opposite directions, and both of them have the same speed of 4 mph.
As they move oppositely in a straight line therefore, the distance between them will be the distance travelled by each of them's sum.
Distance covered by Joe in 2 hours= 8 miles
Distance covered by Anita in 2 hours= 8 miles
Therefore, the total distance from each other =16 miles
24.12 because you have to divide 34 into 820 and then you get 24.12
you're given the pythagorean theorem, which is a^2 + b^2 = c^2.
what you're trying to find is ?, which is the number under the radical.
let's pretend one leg is a and the other is b.
a = 9
b = 10
so let's plug it into the equation. we get 9^2 + 10^2 = c^2
so that equals 81 + 100 = c^2
181 = c^2
so c will equal the square root of 181. therefore, ? = 181.
hope i helped! good luck.
Answer:
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Step-by-step explanation:
A sphere is a geometrical shape formed from a circle. Some of its parts are: diameter, center, radius circumference, etc.
The center of a sphere is a point at its middle. The diameter is a straight line, e.g a chord, that is drawn from one point on the circumference of a sphere to another point and passes through its center. While radius is a line that is from the center of the sphere to a point on its circumference.
A diameter is twice of a radius, so that:
Radius = 
⇒ Diameter = 2 × Radius
Therefore with respect to the question, Gregoire is correct because a diameter is a chord that passes through the center of the sphere.
