If $6,000 is invested for six years and seven months at 6% compounded semi-annually, what is the interest that the investment ea

Vera_Pavlovna [14]

Answer: Option (B) is correct.

Given:

P = $6000

r = 6%

t = 6 years and 7 months = 79 months

∵ It is compounded semi-annually

∴ $I = P\times(1+\frac{r/2}{100})^{\frac{t}{6} } - P$

$I = 6000\times(1+\frac{6/2}{100})^{\frac{79}{6} } - 6000$

I = 8854.72 - 6000

I = 2854.72

$|\Omega|=(\text{the area of the triangle})=\dfrac{a^2\sqrt3}{4}=\dfrac{3^2\sqrt3}{4}=\dfrac{9\sqrt3}{4}\\|A|=(\text{the area of the sector})=\dfrac{\alpha\pi r^2}{360}=\dfrac{60\pi \cdot 1^2}{360}=\dfrac{\pi}{6}\\\\\\P(A)=\dfrac{\dfrac{\pi}{6}}{\dfrac{9\sqrt3}{4}}\\\\P(A)=\dfrac{\pi}{6}\cdot\dfrac{4}{9\sqrt3}\\\\P(A)=\dfrac{2\pi}{27\sqrt3}\\\\P(A)=\dfrac{2\pi\sqrt3}{27\cdot3}\\\\P(A)=\dfrac{2\pi\sqrt3}{81}\approx13.4\%$

Carl has a rock collection. Of the rocks, 3/8 are quartz and 1/3 are granite. What fraction of Carl's rocks are quartz or granit

hoa [83]

Answer:

$\frac{17}{24}$ of Carl's rocks are quartz or granite

Step-by-step explanation:

Proportions and Fractions

A proportion is expressed as a fraction a/b, where a and b are compared by division. If a=b, the proportion (or ratio) equals 1, if a<b, the ratio is less than 1, and if a>b, the ratio is greater than 1. The proportion of elements of a set to the total number of elements of the set is less than one, and the sum of all them equals 1.

We know 3/8 of Carl's rock collection are quartz and 1/3 are granite. If both subsets of rocks are mutually exclusive or disjoint (cannot happen simultaneously), then the proportion of both is the sum of the fractions.

$\displaystyle \frac{3}{8}+\frac{1}{3}=\frac{9+8}{24}=\frac{17}{24}$
