How is a rational number that is not an integer different from a rational number that is an integer?

1 answer:

7 0

That's simple

Real numbers can either be rational or irrational. ... A rational number is a numberwhich can be written as a ratio of two whole numbers (integers). For example 5 is arational number since 5 can be written as ratio of 5 : 1 . 5 is also an integer. 2.5 is arational number since it is a ratio of 5 : 2 .

Hope it helps :)

You have $5600. The best interest rate you can find is 3%

EleoNora [17]

Answer:

18 years

Step-by-step explanation:

The formula for computing accrued amount A for a principal of P at an interest rate of r(in decimal) compounded n times in a year for t years is given by

$A = P(1 + \frac{r}{n})^{nt}$

Note that r is percentage converted to decimal. So 3% = 3/100 = 0.03

We can rearrange the above equation to:

$\frac{A}{P} = (1 + \frac{r}{n})^{nt}$

Taking logs on both sides

$log(\frac{A}{P}) = log(1 + \frac{r}{n})^{nt}$

This gives

$log(\frac{A}{P}) =nt \times log(1 + \frac{r}{n})\\So,\\nt = \frac{log(\frac{A}{P})}{ log(1 + \frac{r}{n})}$

In this particular problem, n = 4, , A= 9600, P = 5600, r =0.03, so r/n = 0.03/4 = 0.0075

1 + r/n = 1+0.0075 = 1.0075

4t = log(9600/5600)/log(1.0075) = log(1.714) / log(1.0075) = 0.234 /0.00325 = 72

t = 72/4 = 18 years

May you please help me figure out every angle?

djyliett [7]

Answer:

<D = 82°

<E = 49°

<F = 49°

Step-by-step explanation:

This is an isosceles triangle because two of the sides are the same length which means the 2 bottom angles are the exact same which means we can set them equal to each other to solve for it.

$\frac{2}{8}$ of students only saw jewelry collection

Solution:

Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs

7/8 of the students saw either the jewelry collection or the dinosaurs

To find: Fraction of students only saw jewelry collection

From given statement,

Fraction of students saw dinosaur = $\frac{5}{8}$

Fraction of students saw either the jewelry collection or the dinosaurs = $\frac{7}{8}$

Therefore,

Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur

$\rightarrow \frac{7}{8} - \frac{5}{8} = \frac{7-5}{8} = \frac{2}{8}$

Thus $\frac{2}{8}$ of students only saw jewelry collection
