If you
Let x to be the total number of pages in a book,
then 1/3x = 117
because 117 = 1/3 of a book
The answer is 10.4 because you multiply 0.2 by 52
Answer: C x=-4 and -10
Step-by-step explanation:
Answer:
area of a square = side x side
Step-by-step explanation:
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
