Using basic proportionality theorem

\\ \sf\longmapsto \dfrac{x}{10}=\dfrac{42}{15}

\\ \sf\longmapsto 15x=42(10)

\\ \sf\longmapsto 15x=420

\\ \sf\longmapsto x=\dfrac{420}{15}

\\ \sf\longmapsto x=28

Elan Coil [88]
Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since t<span>he straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function
</span>
\tan 23^{\circ}= \dfrac{\text{Chad's length}}{\text{Chad's shadow length}},

then \tan 23^{\circ}= \dfrac{\text{Chad's length}}{14.3}, \\ \text{Chad's length}=14.3\cdot \tan 23^{\circ}=6.1.<span />

mart [117]
So this problem would be written as this(:

so you start with 331 students together, but then you lose 7 who travel in the cars.

331-7=324

then it would be 324 divided by the 6 buses. that would look like this

324/6
that equals 54.
so in conclusion the answer is 54 students went into each bus:) hope that helps you!
