A parachutists rate during the freefall reaches 189 km/h. What is the rate in meters per second? At this rate how many meters will dead parachutist fall during 10 seconds of free fall? Do not round your answers

Answers

Answer 1
Answer: 1 km = 1000m
1 hr = 3600 s

189 km/h
189 * 1000 / 3600 m/s
189*5/18 m/s
945/18 m/s
315/6 m/s
105/2 m/s
52.5 m/s

in 10 s
52.5*10
525 m

It will take him 40 minutes to run 5 mile.

D) 40 minutes

Answer:

C) 40 minutes

Step-by-step explanation:

It takes Marcus 8 minutes to run a mile. In 40 minutes, Marcus would have ran 5 miles.

1 mile = 8 minutes

5 miles x 8 minutes = 40 minutes to run five miles

A pyramid has a square base that is 160 m on each side. what is the perimeter in kilometers

Answers

Keywords:

perimeter, square, base, pyramid, kilometers, side

For this case we must find the perimeter of the base of a square pyramid, whose side of the square measures 160m. In addition, the measure obtained must be converted to kilometers. So, we have by definition the perimeter of a square is the sum of its sides, which is equivalent to P = 4l, where "l" is the side of the square.

Ifl = 160m, then:

P = 4 * 160m\nP = 640m

Thus, the perimeter of the base of the pyramid is 640m.

On the other hand, by definition: 1Km = 1000m

By making a rule of three we have:

1Km ---------> 1000m

x --------------> 640m

Where "x" represents the perimeter of the base of the pyramid in Km.

x = \frac {640 * 1} {1000}\nx = 0.64km

Thus, the perimeter of the base of the pyramid is 0.64Km

Answer:

The perimeter in kilometers is 0.64

1km=1000m 160m=0.160x4=0.64

Solve the inequality: 3. n - 23 < -2.5

Answers

Answer:

\Huge \boxed{\boxed{\bf{n < 20.5}}}

Step-by-step explanation:

To solve the inequality\tt{n - 23 < -2.5 }, we want to isolate the variable \tt{n}.

Let's begin by adding 23 to both sides of the inequality:

  • \tt{n - 23 + 23 < -2.5 + 23}

This simplifies to:

  • \tt{n < 20.5}

Therefore, the solution to the inequality is \bf{n < 20.5}.
