Answer:
9(4y - 7) = 36y
^^multiple the bracket by the number outside the bracket
P0 = 1000
<span>(A) pt = 1000 + 90t ; 1000 + 90 + 90 + 90 ... </span>
<span>(B) pt = 1000 * 1.03^t ; ((10000 * 1.03) * 1.03)..</span>
3/4 divided by 2 1/2 is 3/10
3/10
He spent $65 of his total $650 leaving him with $585.
650/10=65
650-65=585
or (650/10)-65=585
the / is the division symbol.
<h3><em>The distance from the lighthouse to the boat will be given by:
</em></h3><h3><em>tan θ=opposite/adjacent
</em></h3><h3><em>θ=angle of depression=23
</em></h3><h3><em>opposite= height of the lighthouse
</em></h3><h3><em>adjacent=distance from the boat to the bottom of the light house
</em></h3><h3><em>hence
</em></h3><h3><em>tan 23=210/a
</em></h3><h3><em>thus solving for a we obtain:
</em></h3><h3><em>a=210/tan23
</em></h3><h3><em>hence
</em></h3><h3><em>a=494.73 ft</em></h3><h3><em>HOPE IT HELPS !!!</em></h3>
