I cannot draw its graph but the equation is
70b+30p=2100
when b is for books and p is for pens
The answer is 12c^8/d^2 or answer A
Circumference of circular track, C = 0.5 miles = 0.5×5280 feet = 2640 feet.
We know, circumference in circle is given by :

( Here, r is radius i.e distance of centre from track )
Putting values in above equation :
2 × 3.14 × r = 2640
6.28 × r = 2640
r = 420.38 feet
Therefore, distance between centre and track is 420.38 feet .
Hence, this is the required solution.
Hey there!
To order them from least to greatest, we can convert them each into decimals.
To convert a fraction into a decimal, simply divide the numerator by the denominator.
1)

To convert

into a decimal, simply divide the numerator which is 3, by the denominator which is 5.
3 ÷ 5 = 0.6
So,

is equal to 0.6 as a decimal.
2)

To convert

into a decimal, simply divide the numerator which is 3, by the denominator which is 7.
3 ÷ 7 = 0.43 approximately
So,

is equal to 0.43 as a decimal. (approximately)
3)

To convert

into a decimal, simply divide the numerator which is 3, by the denominator which is 4.
3 ÷ 4 = 0.75
So,

is equal to 0.75 as a decimal.

⇒ 0.6

⇒ 0.43

⇒ 0.75
So, from least to greatest, the order is:
