Explain why rational numbers are "friendly."

Answers

Answer:

What makes a number friendly?

In number theory, friendly numbers are two or more natural numbers with a common abundancy index, the ratio between the sum of divisors of a number and the number itself. Two numbers with the same "abundancy" form a friendly pair; n numbers with the same "abundancy" form a friendly n-tuple.

253 19/26 rounded to the nearest ten

Answers

Answer:

250

Step-by-step explanation:

As a decimal 253 and 19/23 can be written as 253.73

If we think about 253.73 being closer to 250 or 260, we can see that it is closer to 250, so that is the nearest ten we will round to.

Even if it is too difficult to convert to a decimal, if we round 19/23 to 23/23, our number becomes 254. The nearest ten is still 250.

Graphing Asymptotes for Rational Functions

Two copies of the same Rational Functions are shown below.

On the graph on the left, draw the Horizontal Asymptote and write the equation for the horizontal asymptote underneath.

On the graph on the right, draw the Vertical Asymptote and write the equation for the Vertical Asymptote underneath.

Answers

Answer:

Horizontal Asymptote:    y=2

Vertical Asymptote: x=3

Step-by-step explanation:

One way: Look at graph

Look at for a horizontal or vertical line that both lines don't touch.

Second Way:

When you look for vertical asymptotes, you set the denominator equal to zero and solve.

For example, the second question has a denominator of x-3.

x-3=0

x=3 (This is the vertical asymptote)

When you look for horizontal asymptote, you do long division.

For example, the first question [tex]f(x)=\frac{2x}{x-3}[/tex]

The answer will be 2. 2 is the quotient. You only want quotient not remainder.

y=2.

evaluate the expression (2.5)^3

Answers

The value of the expression is 15.625.

We have,

Expression:

(2.5)³

The base is 2.5 and the power is 3.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

This can be written as,

= 2.5 x 2.5 x 2.5

Convert the decimals into fractions.

= 25/10 x 25/10 x 25/10

Simplify the fractions.

= 15.625

Thus,

$4.03

Step-by-step explanation:

because 15% of 3.50 is 0.525

take 0.525 and round it up (0.53)

3.50 + 0.53 = $4.03

Answer:

$4.03

Step-by-step explanation:

there are two ways to work this problem:

a) find out what 15% of 3.50 and add it to 3.50; requires two steps

b) multiply 3.50 and 1.15 which will give you the answer in one step

Solutions:

a) 3.5 × .15 = 0.5250 which is 0.53 rounded to the nearest penny

now add 3.50 and 0.53 to get 4.03

b) multiply 3.50 and 1.15 to get 4.025 and round to 4.03

How do you solve 4 over 5 times 3.75

Answers

Answer:

3

Step-by-step explanation:

First of all simplify 4/5 to .8

Then Multiply:    .8*3.75=3

9514 1404 393

Answer:

  4/5×3.75 = 3

Step-by-step explanation:

There are many solution strategies available. Among them are ...

use a calculator to find 4/5×3.75 = 3convert the numbers to decimal and multiply by hand 0.8×3.75 = 3.000compute 2(2×3.75)/5 = 2(7.5)/5 = 15/5 = 3 in your headconvert 3.75 to an improper fraction and multiply (4/5)(15/4)=15/5=3

__

Additional comment

The mental arithmetic involved in adding a number to itself (doubling a number) is usually pretty easy. This means it is relatively easy to multiply by powers of 2, such as 4, 8, or 16. The second strategy listed above can be done in your head as ...

  8/10×3.75 = 2×(2×(2×3.75))/10 = 2×(2×7.5)/10 = 2×15/10 = 30/10 = 3

The same product can be found as ...

  8/10×3.75 = 8×(3.75/10) = 8×0.375 = 8×(3/8) = 3

In all cases, it is helpful to know your times tables, decimal equivalents of common fractions, and a few shortcut strategies for mental arithmetic. These are not difficult, but they do require you put some effort into memorizing them.
