brad built 1/4 of a model airplane on monday and 2/3 of it on tuesday. he finished building the airplane on wednesday. what frac
Inessa05 [86]
Teh answer is 1/12. 1/4+ 2/3 is 11/12. First, you need to find the common denominator of 4 and 3, and that is 12.Then, you multiply 1*3 because 4*3 is 12.You then have the fraction of 3/12. Then, you multiply 2*4 because again, what you do to the top, you also do to the bottom, so you would also have the fraction of 8/12.The rest is easy. 3/12 + 8/12 is 11/12.And the missing piece of 11/12 is 1/12, because that made it whole.
Hope that helps!

Convert to standard form of the equation into the slope intercept form -3x-5y=-15
Mamont248 [21]
Our goal is to get y by itself
We will first add 3x to both sides to get
-5y = 3x - 15
We will then divide both sides by -5 to get y by itself which becomes
y = -3/5x + 3

Let us suppose that one of the fireworks is launched from the top of the building with an initial upward velocity of 150 ft/s an
ivanzaharov [21]

Answer:

9.6 seconds

Step-by-step explanation:

The equation for projectile motion in feet is h(t)=-16t^2+v_0t+h_0 where v_0 is the initial velocity in ft/s and h_0 is the initial height in feet.

We are given that the initial upward velocity is v_0=150ft/sec and the initial height is h_0=35ft. Thus, plugging these values into our equation, we get h(t)=-16t^2+150t+35 as our equation for the situation.

The firework will land, assuming it doesn't explode, when h(t)=0, thus:

h(t)=-16t^2+150t+35\\\\0=-16t^2+150t+35\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-150\pm\sqrt{150^2-4(-16)(35)}}{2(-16)}\\ \\t=\frac{-150\pm\sqrt{22500+2240}}{-32}\\\\t=\frac{-150\pm\sqrt{24740}}{-32}\\\\t=\frac{-150\pm2\sqrt{6185}}{-32}\\ \\t=\frac{75\pm\sqrt{6185}}{16}\\\\t_1\approx-0.2\\\\t_2\approx9.6

Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.
