Sq.root of 1240 is approx 35 mm
Join the centre O to the chord (let it be MN) & let OH be the perpendicular to the chord
OH bisects MN into 2 equal parts (each one is x/2)
OMH is a right triangle with one side =8, the second leg =x/2 & the hypotenuse = 12 (Radius)
Apply Pythagoras:
12² = 8² +(x/2)² ==>144=64 + x²/4 ==> x²=4(144-64) =320
x²=320==> x=√320 =17.88 ≈17.9
Answer:
Step-by-step explanation:
To find the distance between two points, 
and 
, you can use the following distance formula:
Plugging in the points from the problem, you'll get the following:
40 apps.
Explanation:
60 divided by 12 is 5. That’s how many downloading sessions could fit in a minute. Multiply 5 by the number of apps, which is 8. Your answer is 40 apps.
You plug in x + 8 for y in the second equation.
answer: x + x + 8 = 2
