Answer:
280.8
Step-by-step explanation:
Since 100% is the full amount, and it is 35% off you add 35 to the 100. So you get 1.35. You finally multiply by 207 and get 280.8
Answer: Assume the cross section is taken at the same height where the circumference was measured. Then
48/3 = 16 inches, close enough, actually. Trees aren't cylinders.
48 × 7 / 22 inches = 15.2727272
48/3.1415926 = 15.2788747
48/pi = 15.2788745368219522338128412837... ☺️
Step-by-step explanation:
circumference / diameter = pi = 3.1415926......
So diameter = circumference / pi.
Answer:
P is price per lawn, 20 is the money made per lawn, L is the number of lawns mowed, 100 is his initial cost.

Answer: 
Step-by-step explanation:
Let be "x" the amount of miles light will travel in 4,200,000 seconds.
Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:
According to the exercise, light travels
miles in 1 second.
Therefore, based on this data, you can set up the following proportion:

And finally, you must solve for "x" in order to find its value.
(Remember the Product of powers property:
)
Then:

Answer: n = 63
Step-by-step explanation:
n ÷ 21 = 3
Do the opposite to find n!
3 × 21 = 63
So, to check our answer
63 ÷ 21 = 3
n = 3
