Answer: 31
Step-by-step explanation:
(x/5) - 1 = 5.2
x/5 = 6.2
x = 6.2 x 5
x = 31
The length of the band in terms of π is given by the expression:
L = 40mm + π*10mm
<h3>
How to get the length of the band?</h3>
Remember that for a circle of diameter D, the circumference is:
C = π*D.
Now, if you look at the image, you can see that the length of the band will be equal to 4 times the diameter of the pencils (one time for each side). Plus 4 times one-fourth of the circumference of each pencil (for the four corners).
because the diameter is 10mm, the length of the band will be:
L = 4*10mm + 4*(π*10mm/4)
L = 40mm + π*10mm
This is the length of the band in terms of π.

<span><span>Let x be the maximum speed of the plane and y be the speed of the wind
***Note: D = r*t or r = D/t***
x +y = 525mph |2100mi/4hr = 525mph
x -y = 350mph |2100mi/6hr = 350mph
2x = 875
x = 437.5mph, speed of plane. Wind speed is 87.5

Multiply 3 and 3.3 to get x. it’s division so you do the opposite which is multiplication
it is 10 first subtract 40 from 25 percent and then subtract 15 from 5
