A. x = 7 , 1
B. x = -7 , 1
C. x = 7 , -1
Answer:
b. 48,000
c. 47,268.569
d. 47,000
The required number would be 47,268.569 which is rounded to the thousandths place which is the correct answer would be option (C)
Rounded to the closest thousandths means a multiple of 1000 which is near to the number. The decimal point is followed by the number closest to the tenth, and the hundredth place number is used to decide whether or not the value should be rounded. Leave it alone if it is four or less; if it is four to nine, bump it up one.
We have to determine Round the number 47,268.568593 to the thousandth place.
⇒ 47,268.568593
Rounded to the nearest thousandths.
⇒ 47,268.569
Therefore, the required number is 47,268.569 which is rounded to the thousandths place which is the correct answer would be option (C)

Piano Tempo
What is the tempo, in beats per minute, of the piano?
beats per minute
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
