We can write an equation to represent this problem:
.525x=25.83
Divide by .525
x=49.2
52.5% of 49.2 is 25.83

The variable $x$ varies directly as the square of $y$, and $y$ varies directly as the cube of $z$. If $x$ equals $-16$ when $z$
Kisachek [45]

If x varies directly as y^2, then there is some constant a for which

x=ay^2

Similarly, there is some constant b such that

y=bz^3

Given that x=-16 when z=2, we have

\begin{cases}-16=ay^2\\y=8b\end{cases}\implies-16=a(8b)^2\implies ab^2=-\dfrac14

Now when z=\frac12, we get

\begin{cases}x=ay^2\\y=\frac b8\end{cases}\implies x=a\left(\dfrac b8\right)^2=\dfrac{ab^2}{64}=\dfrac{-\frac14}{64}=\boxed{-\dfrac1{256}}

Solve for x. Round to the nearest TENTH of a degree. Type your answer as a single value (don't type "x=" or include any labels).
8090 [49]

Answer:

x = 36.9

Step-by-step explanation:

Use the sine function if you know the length of the opposite side and the hypotenuse. Plug your values into the equation: sine (x) = opposite ÷ hypotenuse. Say that the length of the opposite side is 6 and the length of the hypotenuse is 10. Divide 6 by 10, which is equal to 0.6. Now you know that sine (x) = 0.6 which is the same as x = sine^-1 (0.6).

Steps:

sin (x) = 6/10

sin(x) = 0.6

then we do sin^-1(0.6), which equals 36.869897645844 ° (degrees)

36.869897645844 ° (degrees) rounded to the nearest tenth is 36.9

so x = 36.9
