First off, we see the y-intercept is at (0, 240), allowing us to eliminate F and H.

Then we look for the slope: the line decreases from 240 to 210 (a change of -30) when traveling 300 miles (a change of 300). Since the slope is rise over run, we have -30/300=-1/10.

Therefore, the correct answer is J.

Instruction: use the ratio of a 30-60-90 triangle to solve for the variables. Leave your answers as radicals in simplest form.u=

almond37 [142]

Let's start by identify a 30-60-90 triangle

If we compare those two traingles we can stablish the following relation:

$\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}$

Therefore, a=6

u is the opposite side to the 90° angle, therefore

$\begin{gathered} u=2a \\ u=2\cdot6 \\ u=12 \end{gathered}$

on the other hand, v is the opposite side to the 30° angles, so

$\begin{gathered} v=a \\ v=6 \end{gathered}$

zvonat [6]

There are <em><u>25 danishes </u></em>contain cream filling

<h3>Further explanation</h3>

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)

Formula used:

$\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}$

Fractions either proper or mixed (consisting of numerators and denominators) or decimal forms

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert proper fractions to percent forms is by multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number

35% from Several trays of danishes are filled with cream

There are four (4) trays

18 danishes on each tray

Total danishes :

$\displaystyle =18\times 4\\\\=72\:danishes$

35% are filled with cream

$\displaystyle = \frac{35}{100}\times 72\\\\=\boxed{\bold{25.2}}$

Round up to<em><u> </u></em><em><u>25 danishes</u></em>
