6x+6y=30 and 4x+8y=30.60

Ipatiy [6.2K]

<span>Simplifying 4x + 8y = 30.60 Solving 4x + 8y = 30.60 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8y' to each side of the equation. 4x + 8y + -8y = 30.60 + -8y Combine like terms: 8y + -8y = 0 4x + 0 = 30.60 + -8y 4x = 30.60 + -8y Divide each side by '4'. x = 7.65 + -2y Simplifying x = 7.65 + -2y</span>

1. A penny is dropped from the top of the empire state building. The function h(t) = -16t^2 +1250 describes the height of the pe

liubo4ka [24]

Answer: $8.83\ s$

Step-by-step explanation:

Given

Height of the dropped penny is given by

$h(t)=-16t^2+1250$

When penny hit the ground, $h(t)=0$

$\therefore -16t^2+1250=0\\\Rightarrow 16t^2=1250\\\\\Rightarrow t^2=\dfrac{1250}{16}\\\\\Rightarrow t=\sqrt{\dfrac{1250}{16}}\\\\\Rightarrow t=8.83\ s$

Thus, it takes 8.83 s to hit the ground.
