density= mass/volume
mass= densiy x volume
mass= 6.3 g/mm^3 x 30mm^3= 189 g
Answer: 22.4
Explanation:
The pieces of the chords multiply together to get the same result. This is from the intersecting chord theorem.
The first chord has pieces of 10 and x, which multiply to 10*x
This is equal to the other product found by multiplying the pieces 14 and 16 (from the other chord)
10*x = 14*16
10x = 224
x = 224/10 ... divide both sides by 10
x = 22.4
Thrice means three, so 3 times the difference of x and 4.
3(x - 4) < 9
multiply 3 by all in parentheses
(3*x) + (3*-4) < 9
3x - 12 < 9
add 12 to both sides
3x < 21
divide both sides by 3
x < 7
ANSWER: x < 7
