5. Your family decides to take a trip to the Philippines. You have saved up $150 for this trip and need to exchange your U.S dol

lars (USD) for Philippine Pesos (PHP). For every $1 (USD), you will receive $43.29 (PHP).
a. How many Philippine Pesos do you have when you convert all of your money?

b. On the way back home from the Philippines, your family has a layover in Taiwan. The currency in Taiwan is the New Taiwan Dollar (TWD). You have $2,522.50 (PHP) left, how much money do you have to spend in Taiwan if $1 (PHP) is worth $0.69 (TWD)?

c. You finally made it back to the United States, and you have $439.25 (TWD) remaining. You want to convert this back to U.S. dollars. How much money do you have left from your trip if $1 (USD) is $30.05 (TWD)?

Answer:

a.  $6493.5 PHP

b.  $1740.525 TWD

c.  $14.60 US

Step-by-step explanation:

a.

$1 US = 43.26 PHP

150 US = 150(43.26) = 6493.5 PHP

b.

1 PHP = .69 TWD

2522.5 PHP = 2522.5(.69) = 1740.525 TWD

c.

1 US = 30.05 TWD

          439.25 TWD = 439.25/30.05 = $14.60 US

Find the equation for the line is perpendicular to 9x+3y=15 (-3,3)
saw5 [17]

well, let's keep in mind that perpendicular lines have negative reciprocal slopes, so hmmm wait a second, what's the slope of the equation above anyway?

\bf 9x+3y=15\implies 3y=-9x+15\implies y=\cfrac{-9x+15}{3}\implies y=\cfrac{-9x}{3}+\cfrac{15}{3} \\\\\\ y=\stackrel{\stackrel{m}{\downarrow }}{-3}x+5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill

\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-3\implies -\cfrac{3}{1}}\qquad \qquad \qquad \stackrel{reciprocal}{-\cfrac{1}{3}}\qquad \stackrel{negative~reciprocal}{\cfrac{1}{3}}}

so then, we're really looking for the equation of a line whose slope is 1/3 and runs through (-3,3)

\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{3})~\hspace{10em} \stackrel{slope}{m}\implies \cfrac{1}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{\cfrac{1}{3}}[x-\stackrel{x_1}{(-3)}] \\\\\\ y-3=\cfrac{1}{3}(x+3)\implies y-3=\cfrac{1}{3}+1\implies y=\cfrac{1}{3}x+4

Someone help me im struggling.

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.

So we have :

{h}^{2} =  {a}^{2} +  {b}^{2}

{h}^{2} = 64 + 9

{h}^{2} = 73

h =  \sqrt{73}

_________________________________

Step (2)

Now we another using of Pythagorean theorem for finding d :

{d}^{2} =  {h}^{2} +  {c}^{2}

{d}^{2} = 73 + 16

{d}^{2} = 89

d =  \sqrt{89}

d = 9.4

_________________________________

And we're done.

Thanks for watching buddy good luck.

What does x equal in 28 = -2-5x
s2008m [1.1K]
X = 6

28 = -2 - 5x
28 + 2 = 5x
30 = 5x
30/5 = 5x/5 (we divide by five on both side because we want x to be by itself)
6 = x
