$\frac{19}{20}-\frac{11}{20}=\frac{19-11}{20}=\boxed{\frac{8}{20}=\frac{8:4}{20:4}=\frac{2}{5}}$

Answer:

19/20-11/20 is 8/20, or 2/5 in simplest form.

Step-by-step Explanation:

These are both like terms already, so you can just subtract: 19-11=8

Then, since they both have the same denominator, you will just take 8 and put it over 20, like so: 8/20

However, this fraction can be simplified.

The GCF of these two numbers is 4. So, 8÷4=2 and 20÷4=5

So, 2 is the numerator and 5 is the denominator, meaning that you would have 2/5 as your answer.

We can observe that the function describing the graph is linear and so the equation is of linear nature:

$y=mx+n$

Numbers m and n have special names. m is called the slope, n is called y-intercept.

From the graph one can tell that the line intercepts y-axis at y = -1 that means n = -1. What about the slope you say?

The slope can be calculated using two points' coordinates that lie on the line:

$m=\frac{\Delta y}{\Delta x}=\frac{-1-5}{0-5}=\frac{6}{5}$

Now our line has an equation,

$y=\frac{6}{5}x-1$

Hope this helps.

Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :)

You are asked to choose a vowel (a, e, i, o, u) from a list, and then to choose either the number 6 or 7. How many possible outc

faltersainse [42]

Answer:

10 possible outcomes

S = {a6, a7, e6, e7, i6, i7, o6, o7, u6, u7}

Step-by-step explanation:

As there are 5 vowels and 2 numbers that have to be chosen, the total outcomes are

= 5x2 = 10

Each vowel can be chosen with 6 or with 7

Let S be the sample space

a vowel will be chosen first then there is possibility that either the number chosen with it is either 6 or 7 so each vowel will have two possible outcomes with the number

S = {a6, a7, e6, e7, i6, i7, o6, o7, u6, u7} ..
