Answer:

StartFraction StartRoot 3 EndRoot Over 3 EndFraction

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

we know that

In the right triangle XYZ

cos(Y)=\frac{ZY}{XY} ---> adjacent side divided by the hypotenuse

substitute the values

cos(30\°)=\frac{ZY}{4}

Remember that

cos(30\°)=\frac{\sqrt{3}}{2}

so

substitute

\frac{\sqrt{3}}{2}=\frac{ZY}{4}

ZY=(4)\frac{\sqrt{3}}{2}

ZY=2\sqrt{3}\ units

step 2

sin(Y)=\frac{XZ}{XY} --> opposite side divided by the hypotenuse

substitute the values

sin(30\°)=\frac{XZ}{4}

Remember that

sin(30\°)=\frac{1}{2}

so

\frac{1}{2}=\frac{XZ}{4}

XZ=2\ units

step 3

tan(Y)=\frac{XZ}{ZY} --> opposite side divided by adjacent side

substitute the values

tan(Y)=\frac{2}{2\sqrt{3}}

tan(Y)=\frac{1}{\sqrt{3}}

Simplify

tan(Y)=\frac{\sqrt{3}}{3}

so

Samantha took out two loans totaling $6,000 to pay her first year of college. She borrowed the maximum amount she could at 3.5%
Sidana [21]
Our simple interest formula is <em>I = prt</em>, where <em>I</em> is the amount of interest, <em>p</em> is the amount of principal, <em>r</em> is the percentage written as a decimal, and <em>t</em> is the amount of time (in this case in years).  We will define our variable <em>x</em> as the amount borrowed at the lower percentage rate.  Our formula would then look like
I=x(0.035)(1) \\ =0.035x.  (Remember that when we convert percentages to decimals, we divide by 100; 3.5/100 = 0.035.)
The remaining money borrowed was invested at 7% interest.  The expression to represent the remaining money would be 6000 - <em>x</em>, as it is what was left over to borrow.  The interest formula for this loan would be
I=(6000-x)(0.07)(1). (Again, we must divide 7 by 100 to convert the percentage; 7/100=0.07.)
Using the distributive property we have:
I=6000*0.07-x*0.07 \\ =420-0.07x (<em>t</em> in this case is 1, since it is 1 year.)
The total amount of interest for both loans for one year was $259, so we have:
259=0.035x+420-0.07x
Combine our like terms:
259=-0.035x+420
Cancel 420 by subtracting:
259-420=-0.035x+420-420 \\ -161=-0.035x
Cancel -0.035 by dividing:
\frac{-161}{-0.035}=\frac{-0.035x}{-0.035} \\ 4600=x
This means she borrowed $4600 at the lower interest rate.  The remainder would be $6000-$4600=$1400 at the higher interest rate.
