The sum of<span> the three interior </span>angles<span> always add to 180°.

40</span>° + y° + 30° + y° = 180°
40° + 2y° + 30° = 180°
70° + 2y° = 180°
2y° = 110°
<u>y° = 55°</u>

Gennadij [26K]

<h2>Explanation:</h2>

In this problem we have a pumpkin is launched from the top of a 20 foot tall platform at an initial velocity of 84 feet per second. So the height, h, of the pumpkin at time t seconds after the launch can be modeled by the equation:

$h(t) = -16t^2 + 84t + 20$

So this is the equation of a parabola. The maximum of this parabola occurs at its vertex. So let's find this vertex:

$\text{The x-value of the vertex is}: \\ \\ t=-\frac{b}{2a} \\ \\ \\ Where: \\ \\ a=-16 \\ \\ b=84 \\ \\ c=20 \\ \\ \\ t=-\frac{84}{2(-16)} \\ \\ t=-\frac{84}{-32} \\ \\ t=\frac{21}{8}=2.625 \\ \\ h(2.625)=-16(2.625)^2+84(2.625)+20 \\ \\ h(2.625)=-110.25+220.5+20 \\ \\ h(2.625)=130.25m$

Finally, the maximum occurs at time 2.625 seconds when the height is 130.25m

Your commission is $60 for

klio [65]

It’s C becuase when you divide the 700$ by 200$, you will get 3.5. So you basically multiply it with 60$ and there you have your answer which is 60*3 + 60*0.5=210
