What simple interest rate is needed for $6,000 to earn $1,000 in 15 months
Mekhanik [1.2K]

let's recall that a year has 12 months, so 15  months is really 15/12 years.

\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill&\$1000\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\to \frac{15}{12}\dotfill &\frac{5}{4} \end{cases}

\bf 1000=(6000)r\left( \cfrac{5}{4} \right)\implies 1000=7500r\implies \cfrac{1000}{7500}=r\implies \cfrac{2}{15}=r \\\\\\ \stackrel{\textit{converting that to a percentage}}{\cfrac{2}{15}\cdot 100 = r\implies \cfrac{40}{3}=r}\implies \stackrel{\%~\hfill }{13.\overline{3}}=r

Find sin theta if cot theta =-4 and cos theta &lt; 0
asambeis [7]
Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).

Then the hypotenuse length is √(1+4²) = √17.

The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so

sin(\theta) = \frac4{\sqrt{17}}

What is 155.78=2.95h+73.18<br> a. 28<br> b. 36<br> c. 3.6<br> d. none of these
xz_007 [3.2K]

Answer:

a. 28

Step-by-step explanation:

Given:

155.78=2.95h+73.18

We need to evaluate given expression to find the value of 'h'.

Solution:

155.78=2.95h+73.18

Now first we will apply Subtraction property of equality and subtract both side by 73.18 we get;

155.78-73.18=2.95h+73.18-73.18\\\\82.6=2.95h

Now we will use Division property of equality and divide both side by 2.95 we get;

\frac{82.6}{2.95}=\frac{2.95h}{2.95}\\\\h=28

Hence After evaluating given expression we get the value of 'h' as 28.
