4 0

You can set up a proportion for 36 copies to 1 minute and x copies for 3 minutes and 15 seconds (15 seconds is a fourth of a minute, so it would be .25

36/1=x/3.25

Then just cross multiply to get

117=x

You can also simply multiply 36 by 3.25 since 36 copies are made in 1 minute

36 x 3 = 108

60/15 = 4
36/4 = 3.75

108 + 3.75 = 111.75
Answer: 111.75 copies

What is the equation of the line that passes through the points (-2,2) and (0,5)

gregori [183]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -2}}\quad ,&{{ 2}})\quad 
% (c,d)
&({{ 0}}\quad ,&{{ 5}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{5-2}{0-(-2)}\implies \cfrac{5-2}{0+2}
\\\\\\
\cfrac{3}{2}$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-2=\cfrac{3}{2}(x-(-2))\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-2=\cfrac{3}{2}(x+2)\implies y-2=\cfrac{3}{2}x+3\implies y=\cfrac{3}{2}x+3+2
\\\\\\
y=\cfrac{3}{2}x+5$

(3x-4)/(14)=(9)/(10) Solve the proportion. Round to the tenths

____ [38]

The value of "x" is 5.5

<em><u>Solution:</u></em>

Given that we have to solve the proportion

$\frac{3x - 4}{14} = \frac{9}{10}$

We can solve the above given proportion for "x" by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable "x"

$\rightarrow \frac{3x - 4}{14} = \frac{9}{10}\\\\\rightarrow 10(3x - 4) = 14 \times 9\\\\\rightarrow 30x - 40 = 126\\\\\rightarrow 30x = 126 + 40\\\\\rightarrow 30x = 166\\\\\rightarrow x = 5.533$

On rounding to nearest tenth we get 5.5

Thus value of "x" is 5.5
