im not sure exactly but that the answer i got
Call the hypotenuse of the 60° triangle "y". Then the definition of the sine function tells you
... sin(60°) = (8√2)/y
or (multiplying by y/sin(60°))
... y = (8√2)/sin(60°) = (8√2)/(√3/2) = (16/3)√6
Similarly, the definition of the sine function applied to the larger triangle tells you
... sin(45°) = y/x
or
... x = y/sin(45°) = ((16/3)√6)/(1/√2) = (32/3)√3 . . . . matches selection C.
X + y = 9 .....x = 9 - y
0.02x + 0.04y = 0.24
0.02(9 - y) + 0.04y = 0.24
0.18 - 0.02y + 0.04y = 0.24
-0.02y + 0.04y = 0.24 - 0.18
0.02y = 0.06
y = 0.06 / 0.02
y = 3......4% milk
x + y = 9
x + 3 = 9
x = 9 - 3
x = 6 ....2% milk
Nathan used twice as much 2% milk as 4% milk....u r correct
This is saying that four is the result of a number "x" minus 12....therefore the equation is x-12=4
If 90% of bodies are water weight, then we have 10% left.
76+10% = 83.6.
83.6 total.
