7 0

Let’s first find the rate that she types at in wok.
128/3 = 42+2/3 words per minute.
Now divide 576 by the rate.
576/42.666= 13.5 minutes

Lostsunrise [7]

Answer:

Volume = 112

Step-by-step explanation:

formula: V = (1/3) × L × W × h,

$formula: V = ( \frac{1}{3} ) × L × W × h, \\ = \frac{1}{3} \times 8 \times 7 \times 6 \\ divide \: both \: 3 \: and \: 6 \\ = 1 \times 8 \times 7 \times 2 \\ = 56 \times 2 \\ = 112$

Find the coordinates of the missing endpoint if B is the midpoint of AC. C(-5,4), B(-2,5) I need the steps and answer pls and ty

mylen [45]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
A&({{ x}}\quad ,&{{ y}})\quad 
% (c,d)
C&({{ -5}}\quad ,&{{ 4}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)$

$\bf \left( \cfrac{-5+x}{2}~,~\cfrac{4+y}{2} \right)=\stackrel{B}{(-2,5)}\implies 
\begin{cases}
\cfrac{-5+x}{2}=-2\\\\
-5+x=-4\\
\boxed{x=1}\\
----------\\
\cfrac{4+y}{2}=5\\\\
4+y=10\\
\boxed{y=6}
\end{cases}$

1000/t + 50

Asymptotes:

t = 0

If the loan is to be paid in 0 months, the amount is very large
