The school band is going to buy candy bars for $430 and sell them at school for $1.50 each. The band has to raise $1,350 to help

Answer:

x = 900 or 1.50 * x = 1,350 (Though I advise you to use x = 900)

Step-by-step explanation:

Divide 1,350 by 1.50 to see that they need to sell exactly 900 bars. We can fact check by using a calculator to do the equation 1.50 * 900 = 1,350.

Answer:

$\theta=287^o$

Step-by-step explanation:

<u>Position in the Plane </u>

If we place an object in a plane and mesure its x and y coordinates, we are referencig its position according to the rectangular system. Other popular way to reference positions is in polar form or magnitude-angle form. If we have the rectangular coordinates (x,y), we can easily find the polar coordinates $(r,\theta)$ (and vice-versa). We use the formulas

$r=\sqrt{x^2+y^2}$

$\displaystyle tan\theta=\frac{y}{x}$

We have x=31.4 Km East (a positive coordinate) and y=-102.5 Km South (negative because it's pointing downwards). we need to find the angle respect to the East reference where $\theta=0^o$ . Check the image below for reference.
