Answer:

the answer is 10

Step-by-step explanation:

the line AC devides OB at point E which is the midpoint of line OB meaning line AC cuts OB evenly therefore line OE and EB are the same length added together they make up OB which is half the diameter of circle O because O is center point and half the diameter is the radius. If OE is 5 then EB is too and added together they make 10

A)48

Explanation:

2^3 - 2^2 = 8 - 4 = 4
3^3 - 3^2 = 27 - 9 = 18
4^3 - 4^2 = 64 - 16 = 48
5^3 - 5^2 = 125 - 25 = 100
6^3 - 6^2 = 216 - 36 = 180
7^3 - 7^2 = 343 - 49 = 294
8^3 - 8^2 = 512 - 64 = 448

A person on a moving sidewalk travels 40 feet in 8 seconds. The moving sidewalk has a length of 200 feet. How long will it take

beks73 [17]

Answer:

The man covers 200 ft in 40 seconds.

Step-by-step explanation:

A person is moving on the sidewalk from one end to the other end.

He walks 40 feet in 8 seconds.

Therefore his speed = $\frac{distance covered}{time}$

= $\frac{40}{8}$

= 5 ft/ $s^{2}$

He covers the sidewalk distance at a rate of 5 feet every second.

To calculate the time taken to cover 200 ft,

time = $\frac{distance to be covered}{speed}$

time = $\frac{200}{5}$

<u>time = 40 seconds</u>

Hence the man covers 200 ft in 40 seconds.
