Chord AB = ?
Chord AB = AC + CB

Chord HI = HC + CI
HC = 7
CI = 28
Chord HI = 7 + 28 = 35

Chord AB = Chord HI

CB is 4 times the Length of AC. Let AC be X.

x + 4x = 35
5x = 35
x = 35/5
x = 7

AC = x = 7
CB = 4x = 4(7) = 28

Step-by-step explanation:

2 \times  \frac{22}{7}  \times 14 \times 43

= 2 \times 22 \times 2 \times 43

Ben visits the park every 2 days and goes to the library every 5 days. if ben gets to do both of these today, how many days will
Alex Ar [27]
You could label "today" as "0."

Park every 2 days:  2, 4, 6, 8, 10, 12, 14, (etc.) days
Library every 5 days:  5, 10, 15, 20 (etc.)

You can see that the smallest number of days that must go by before Ben can do both things on one day is 10.
