Answers

Answer:

It took 3 hours for the two to meet, and they were 12 miles from Joseph's home when they met.

Step-by-step explanation:

Since Joseph is planning to meet up with his friend Naomi, and Joseph jogs from his house traveling at a rate of 4 miles per hour, while Naomi is initially 27 miles from Joseph's house and travels towards Joseph at 5 miles per hour, for To determine how many hours went by before they met and how many miles were they from Joseph's house when they met, the following calculations should be performed:

27 - (4 + 5) = 27 - 9 = 18

27 - (4 + 5) x 3 = 0

Therefore, it took 3 hours for the two to meet.

4 x 3 = 12

Thus, they were 12 miles from Joseph's home when they met.

Hey circle is divided into 24 sectors are shown below the sectors were rearranged into the figure shown below by placing the sector side-by-side this figure can be used to derive the equation for the area of a circle which statement about the figure is true

Answers

Answer:

the answer is two

Step-by-step explanation:

The equation is

The figure is similar to a parallelogram , with a base length equivalent to the circumference of the circle and a height equivalent to the radius of the circle

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the radius of the circle be represented as r

Now , the equation will be

The circumference of the circle C = 2πr

And , the circle is divided into 24 sectors and it is placed side-by-side

The figure formed is in the shape of a parallelogram

The base length of the parallelogram = circumference of the circle

And ,

Height of the parallelogram = radius of the circle r

Hence , the base length is the circumference and height is the radius of the circle

10^7 (its just 10 times itself 7 times) = 10,000,000
