Answer:

480 inches cubed

Step-by-step explanation:

Volume= l*w*h

Volume= 12*8*2.5

Volume= 240 inches cubed

The problem asks for the volume of TWO boxes so multiply the volume by 2 and you get a volume of 480 inches cubed

Answer:

6 5/12 and 5 1/30

Step-by-step explanation:

Just simplify both sides of the equation.

1 3/4 + 1/6 + x = 7 1/2 ---> 1 11/12 + x =7 1/2

then subtract the 1 11/12 from both sides

x = 6 5/12

H=7 + 29t-16t^2 find all values of t for which the balls height is 19ft

NikAS [45]

$\bf \qquad \textit{initial velocity}\\\\
\begin{array}{llll}
\qquad \textit{in feet}\\\\
h(t) = -16t^2+v_ot+h_o
\end{array} 
\quad 
\begin{cases}
v_o=\textit{initial velocity of the object}\\
h_o=\textit{initial height of the object}\\
h=\textit{height of the object at "t" seconds}
\end{cases}\\\\
-------------------------------\\\\$

$\bf h(t)=7+29t-16t^2\qquad h(t)=19\implies 19=7+29t-16t^2
\\\\\\
16t^2-29t+12=0\impliedby \textit{now, let's use the quadratic formula}
\\\\\\
t=\cfrac{-(-29)\pm\sqrt{(-29)^2-4(16)(12)}}{2(16)}\implies t=\cfrac{29\pm\sqrt{841-768}}{32}
\\\\\\
t=\cfrac{29\pm\sqrt{73}}{32}\implies t\approx 
\begin{cases}
1.17\\
0.64
\end{cases}$

so hmm check the picture below, thus the ball hits 19 feet of height twice, once on the way up, and once on the way down, at about 0.64 seconds and at 1.17 seconds.
