Solve the equation sin theta = .3 to the nearest tenth. Use the restrictions 90 < theta <180

olga55 [171]

Sinα=3/10

α=arcsin(3/10)°

α≈17.5°

But since we are restricted to 90°<α<180° the angle must lie in the second quadrant so:

α≈(180-17.5)°

α≈162.5°

The time t required to drive a certain distance varies inversely with the speed r. if it takes 4 hours to drive the distance at

Aleksandr [31]

$\bf \qquad \qquad \textit{inverse proportional variation}
\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf \stackrel{\textit{time \underline{t} required to drive a certain distance varies inversely with the speed \underline{r}}}{t=\cfrac{k}{r}}
\\\\\\
\textit{we also know that }
\begin{cases}
t=4\\
r=35
\end{cases}\implies 4=\cfrac{k}{35}\implies 4(35)=k
\\\\\\
140=k\qquad therefore\qquad \boxed{t=\cfrac{140}{r}}
\\\\\\
\textit{now, when \underline{r} = 45, what is \underline{t}?}\qquad t=\cfrac{140}{45}$

Halfway through a bus route, 23 students have been dropped off and 48 students remain on the bus. Write an equation to determine

jonny [76]

Answer: The required equation is

$x=23+48\\\Rightarrow\ x=71$

Thus, there are 71 students on the bus at the beginning of the route.

Step-by-step explanation:

Given: The number of students dropped off = $23$

The number of students remain on the bus = $48$

Let 'x' be the total number of students in the bus then we get the equation as

$x=23+48$

On adding 23 to 48, we get 71

Hence, $x=71$

Therefore, There are 71 students on the bus at the beginning of the route.
