Mean is the average. You would add up all the numbers and divide by how many numbers you have.  433/10=43.3

Alex Ar [27]

Answer:

The acceleration due to gravity on the moon is 1.642 m/s².      

Step-by-step explanation:

Given : In the pendulum formula , we use g = 9.8 m/s2 for the acceleration due to gravity on Earth. If an astronaut on the surface of the moon swings a 1-meter long pendulum, and it has a period of 4.9 seconds.

To find : What is the acceleration due to gravity, g, on the moon?        

Solution :

The pendulum formula is T=2\pi \sqrt{\frac{L}{g}}

where, T is the time period,

L is the length of the pendulum,

g is the acceleration due to gravity

We have to find the value of g acceleration due to gravity on the moon.

The formula became,

g'=(\frac{2\pi}{T})^2\times L

Substitute T=4.9 seconds , L= 1 m

g'=(\frac{2\times 3.14}{4.9})^2\times 1

g'=(\frac{6.28}{4.9})^2

g'=\frac{39.4384}{24.01}

g'=1.642

The acceleration due to gravity on the moon is 1.642 m/s².

Answer:

  $81

Step-by-step explanation:

The garden is 4 yards = 12 feet by 3 yards = 9 feet. The area of it is the product of these dimensions, ...

  (12 ft)(9 ft) = 108 ft²

The cost of fertilizer for that area will be ...

  ($0.75/ft²)(108 ft²) = $81.00

They will spend $81.00 to fertilize the garden.

PLEASE HELP ME WITH THIS QUESTION!!! WHATS THE ANSWER?? I WILL GIVE YOU BRAINLIEST AND A THANKS!!! THANK YOUUU!!! &lt;33
Free_Kalibri [48]

Answer:

A) 113 m²

Step-by-step explanation:

Use the formula for area of a circle.

Area of a circle = πr²

π = pi = 3.14 (rounded)

r = radius

² = the power of 2, or the radius (in this case) multiplied by itself.

Note that the radius is given, and it is 6. Plug in 6 for the radius:

A (circle) = π(6)²

First, solve the power. Multiply 6²:

6² = 6 * 6 = 36

Next, multiply 36 with π (3.14):

36 x 3.14 = 113.04

A) 113 m² is your closest answer.
