Answer:
The answer to this is -32.48
Step-by-step explanation:
What you do first is remove the negative (-) in 2.9. Then multiply, 11.2 times (x) 2.9 equals (=) 32.48. Then you can put the negative (-) back. It should look like this -32.48.
1. tanA = 12 / 25 = 26.
2. radius = 38.4 / 2 = 19.2.
14.7^2 + b^2 = 19.2^2 => b = 12.4, by pythagorean theorem.
Finally, x = 19.2 - 12.4 = 6.8.

Answer:28inches & 84inches
First, lets write an equation that fits the data given. The string is 112 inches long. When the two pieces are cut, the first piece will be three times as long as the second piece. If we use the variable, x, to represent the second piece, we can create the following equation...
112=3x+x
Now lets solve for x.
112=4x
divide both sides by 4
28 inches=x
Now we know that the second piece is 28inches long. Since the first piece is three times as long, simply multiply 28*3 and we'll know the length of the first piece.
28*3=84 inches
28+84=112
Answer:
B (Y, N, N)
Step-by-step explanation:
a) y = 1/3x, so each value satisfies it. This is true.
b) If "a" is "Y" then b has to be no
c) 1 * 11 = 11
2 * 2 = 22
3 * 5 = 15
The last equation does not follow the rules for the previous two equations, so it is no.
Thus, the answer is B (Y, N, N)
