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

bogdanovich [222]

The electric power of microwave is 900 watts.

Step-by-step explanation:

Given,

Voltage in the circuit = 120 volts

Current in the circuit = 7.5 amp

Electric power of microwave = Voltage*Current

Electric power of microwave = 120*7.5

Electric power of microwave = 900 watts

Therefore,

The electric power of microwave is 900 watts.

If -10 is subtracted from a number, the result is 6. what is the number?
brilliants [131]
Subtracting a negative number is the same as adding a positive number

assume your number is n

n - (-10) = 6
n + 10 = 6

subtract 10 from both sides

Factor the expression completely.
densk [106]

Answer:

\fbox{\begin{minipage}{13em}Option D: 2(3x + 4)(3x - 4)\end{minipage}}

Step-by-step explanation:

      A = 18x^{2}  - 32\\

Find the sharing components:

<=> A=2*9*x^{2} - 2*16

Apply the inverse of associative property:

<=> A = 2(9x^{2} - 16)

Identify two square components inside the parenthesis:

<=> A = 2((3x)^{2} - 4^{2} )

Factorize:

<=> A = 2(3x + 4)(3x - 4)

=> Option D is correct

Hope this helps!
