Answers

As you are given multiple choice, you can use trial and error with each of the answers. You can see that with each number the sign before it is reversed (so it goes even, odd , even , odd etc.) and the numbers are halved each time.
The answer is B) because you are dividing by 2 each time, and changing the sign before the number.

The answer would be b. It is b because if you do 400 divided by -2 is -200 and then you just keep dividing by -2

Answer:

216c³

Step-by-step explanation:

8 yellow = 2³ (sides = 2 cubes)

Green added to cover yellow, making it (2+2)³ = 4³

Red added to cover green, making it (4+2)³ = 6³

Total cubes = 6³ = 216 cubes

Each cube has a volume = c³

Volume of the final cube = 216c³ units³

(x + 5)2 + (y - 7)2 = 36, its radius is

Answers

The answer would be 6

Steps: The equation of a circle is (x – h)² + (y – k)² = r²; since we are trying to find the radius we are going to focus on the r². Now if you look the equation has the 36 filled in as the r² so r² = 36; we now have to isolate the r to get the radius, how do we get the radius? We Square root the r² and 36. After we get r = 6, The radius is 6 units

Dr. Black is standing 13 feet from a streetlamp. The lamp is making his shadow 9 feet long. He estimates that the angle of elevation from the tip of his shadow to the top of the streetlamp is 50. To the nearest foot, the streetlamp is about _____.

Answers

Distance from tip of shadow to lamp post = 13 +9 feet = 22 ft Height of lamp post = x tan 50 = x /22 = 1.192 x = 22 * 1.192 =.26.2 ft. rounded = 26ft

Answer:

26 ft height

Step-by-step explanation:

The distance between the streetlamp and the tip of his shadow is 9 + 13 = 22 ft.

A rectangle triangle is formed in which one side is 22 ft long and the other side is the streetlamp height. The angle between the 22 ft side and the hypotenuse is 50°. From tangent definition:

tan(50°) = (streetlamp height)/(22 ft)

tan(50°) * (22 ft) = streetlamp height

26 ft = streetlamp height
