Amount is directly proportional to weight
thus
A = kw               A  =  amount
                           k  = constant      ^    which is price per gram
                           w =  weight

To convert degrees Fahrenheit (F) into degrees Celsius (C) use the formula 2003-05-04-00-00_files/i0150000.jpg. Rewrite the equa
mihalych1998 [28]
To covert degrees Fahrenheit (F) to degrees Celsius (C) we use the equation C<span> = (</span>F<span> - 32) × 5/9</span> . To convert degrees Celsius (C) to degrees <span>Fahrenheit (F) we have to rewrite the equation. 
First step: Divide both sides by 5/9. The equation would look like this: 
</span>C(9/5) = (F - 32) 

Second step: Add 32 on both sides. 
32 + (9/5)C = F or F = <span>32 + (9/5)C</span>

Y=mx+b is used for what math equation
soldier1979 [14.2K]
       y = m x + b is a linear equation. 
      This equation is in the slope - intercept form, where m is the slope and b is y - intercept.
       For example: y = 2 x + 5
       In this equation: m = 2 ( the slope ) and b = 5 ( the line intercepts y-axis at the point ( 0, 5 )  ).

Answer:

100 beats per minute

Step-by-step explanation:

If it takes 28.8 secs for the piano to play 48 beats, then it would take 60 secs (1 minute) to play x number of beats.

To find the value of x, which is the number of beats the piano makes per minute, let's set the proportion as shown below:

28.8 secs = 48 beats

60 secs = x beats

Cross multiply

28.8*x = 60*48

28.8x = 2,880

Divide both sides by 28.8

x = 2,880/28.8

x = 100

✅Thus, if the Piano plays 48 beats in 28.8 secs, therefore, the tempo of the piano in beats per minute would be 100 BPM

What is the surface area of a sphere with radius 2
Gelneren [198K]

Answer:

A

Step-by-step explanation:

The surface area (A) of a sphere is calculated as

A = 4πr² ← r is the radius

here r = 2, hence

A = 4π × 2² = 4π × 4 = 16π units² → A
