Select the letter of the correct answer
A woman sailed around the globe. Suppose the circumference of the world is 24,901 miles.
Estimate the world's radius in kilometers. Round your answer to the nearest whole kilometer.
Hint
A
6,384 kilometers
B
3,965 kilometers
C
3,256 kilometers
D
7,320 kilometers
It’s b

The estimate value of the world's radius is 6384 kilometers ⇒ A

Step-by-step explanation:

The formula of the circumference of a circle is C = 2πr, where r is the radius of the circle

∵ The circumference of the world is 24,901 miles

∵ C = 2πr

- Substitute C by 24,901 to find r

∴ 24,901 = 2πr

- Divide both sides by 2π

∴ = r

∴ The radius is 3965.127389 miles

Change the mile to kilometer

∵ 1 mile = 1.60934 kilometers

- Multiply the value of the radius by 1.60934

∴ r = 3965.127389 × 1.60934

∴ r = 6381.238111 kilometers

- Round it to the nearest kilometers

∴ r = 6381 kilometers

The world's radius is 6381 kilometers

The nearest choice for this value is A

The estimate value of the world's radius is 6384 kilometers

x=30

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
