You are out bottle caps, and decide to use Popsicle sticks instead. You measure them, and they are 15.2 cm tall. How many Popsic
satela [25.4K]
It depends on how many Popsicle sticks you are going to use.So, for example, say that you are using 5 Popsicle sticks for the model. What you do is 15.2 x 5, 15.2 being the height of the sticks and 5 for the number of sticks you are using. The answer will be 76 cm tall.           21                                                                                                                     15.2                                                                                                               x    5                                                                                                                ---------                                                                                                             76.0

Which line is parallel to 4x + 2y = 0?<br>A. y=2x+3<br>B. -1/2×+3<br>C. y=-2x+3<br>D. y=1/2x+3
egoroff_w [7]
Line A is parallel to line B if line A and B have the same slope and have the same or different y-intercept.

Convert the standard form equation to slope-intercept form as it will be easier to see the slope.

Solve for y.

4x + 2y = 0
2y = -4x <-- Subtract 4x from each side
y = -2x <-- Divide both sides by 2

In the slope-intercept form y = -2x, a y-intercept of 0 is implied

Now find a slope-intercept form equation that has the same slope as y = -2x

So, the answer is C y = -2x + 3.

kicyunya [14]
First..
\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions} \ \textgreater \  \frac{\left(\frac{15}{4}\right)}{\frac{45}{8}}

\mathrm{Divide\:fractions}: \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c} \ \textgreater \  \frac{15\cdot \:8}{4\cdot \:45}

\mathrm{Multiply\:the\:numbers:}\:4\cdot \:45=180 \ \textgreater \  \frac{8\cdot \:15}{180}

\mathrm{Multiply\:the\:numbers:}\:15\cdot \:8=120 \ \textgreater \  \frac{120}{180}

\mathrm{Cancel\:the\:common\:factor:}\:60 \ \textgreater \  \frac{2}{3}

Hope this helps!
