Answer:

option A. 21 sec

Step-by-step explanation:

Speed = the distance over the time

Given:

Speed = 2 m/s  and distance = 42 m and time = t

So,

2 = 42/t

Solve for t

t = 42/2 = 21 sec.

The answer is option A. 21 sec

Mrs. Jones is creating a seating chart for the front row of her classroom. She has 10 possible students to place in the front ro
Lemur [1.5K]

Answer:

5 seats

Step-by-step explanation:

if I'm getting the right idea, the seats are NOT enough

since the number of arrangement of 10 people in a row is

10! = 3628800 which is a lot larger than 30240.

---------------------------------------------------------------------------------------

Let number of seats be

10PX = 30240

\frac{10!}{(10-X)!} = 30240

(10-X)! = \frac{10!}{30240}

(10-X)! = 120

(10-X)! = 5!

10-X = 5

X = 5

snow_tiger [21]

Answer:

  • 5 runs

Step-by-step explanation:

Initial number is 64 players

<u>Number of players reduce twice every run and will be equal to 2 to reach the grand final</u>

  • 64*(1/2)^x = 2
  • (1/2)^x = 1/32
  • 2^-x = 2^-5
  • -x = -5
  • x = 5

Number of runs is 5

64 > 32 > 16 > 8 > 4 > 2

Answer:

right

neither

straight

neither

Step-by-step explanation:

The first angle is a right angle.  The box in the corner indicates a 90 degree angle

The second angle is less than 90 degrees so it is an acute angle

The third angle is a straight line so it is a straight angle.

The fourth angle is wider than 90 degrees  it is an obtuse angle
