9:10
So you have to simplify so it = 9/10 then just turn it into a ratio 9:10
I'm not sure how much the monthly fee is, but assuming it's low, (150/22=6) she would be able to use the fitness club for 6 months.
It is 7.7 because u need to round it to the neares but not everytime;)

The ratio of OC to OA is OC/ 10√2 - OC
<u>Explanation:</u>
Given -
AD = 4 cm
M is the midpoint of CD
Ratio of OC to OA = ?
In a square, all the interior angles are 90°
Therefore,
ΔADC, ΔABC and ΔBCM are right angled triangle
AC is the diagonal which divides ∠DAB and ∠DCB equally
If AD = 4 cm, then AB, BC and DC are also 4cm
In ΔADC,
(AC)² = (AD)² + (DC)²
(AC)² = (10)² + (10)²
AC = 10√2 cm
AC = OA + OC
OA = AC - OC
OC/OA = OC / AC - OC
OC / OA = OC / 10√2 - OC
Therefore, the ratio of OC to OA is OC/ 10√2 - OC
65 MPH (Miles Per Hour) would be 0.0290576 KM (Kilometers).
