How would I write 8.21 as a mixed number?

Answers

Answer 1

Answer:

we know that

A mixed number is a number consisting of a whole number and a proper fraction

we have

$8.21$

$8.21=8+0.21=8+(21)/(100)=8(21)/(100)$

therefore

the answer is

$8(21)/(100)$

Answer 2

Answer:

The value of mixed number of number 8.21 is,

⇒ 8 (21 / 100)

We have to given that;

A number is,

⇒ 8.21

Now, We can simplify as;

⇒ 8.21

⇒ 8.21 × 100 / 100

⇒ 821 / 100

⇒ 8 21/100

Therefore, The value of mixed number of number 8.21 is,

⇒ 8 (21 / 100)

It's about Pythagorean theorem.

AB*AB + BC*BC = AC*AC, so:

35*35 + 25*25 = AC*AC
1225 + 625 = AC*AC
1850 = AC*AC

So AC is a root of 1850, which is ~43 (exactly: 43,01162633521313)

It means that distance between A and C is 43 meters and some milimeters.

Consider the functions f(x) = x2 − 13 and g(x) = x + 5. What is the value of (f − g)(−4)? ...?

Answers

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

f(x) = x2 - 13
g(x) = x + 5

and are asked to compute "f-g" when x=-4. there are two ways of doing this. you can either first find f(-4) and g(-4) and then substract one from other like so:

f(−4)=(−4)2−13=16−13=3
g(−4)=−4+5=1

f(−4)−g(−4)=3−1=2

or you can create a new function that represents "f-g", call it "h", and work out h(-4) as follows:

h(x)=f(x)−g(x)=(x2−13)−(x+5)=x2−13−x−5=x2−x−18
h(−4)=(−4)2−(−4)−18=16+4−18=2

Write 0.55 as a fraction in simplest form

Answers

Hey There :)

0.55 as a fraction would be $(55)/(100)$ because whenever you change decimal to fraction the denominator will always be 100.

Steps to simplify

1. $(55)/(100)$ lcd = 5

2. 55/5= 11 and 100/5=20

3. Final fraction from step 2 is $(11)/(20)$

In conclusion 0.55 changed into a fraction is $(11)/(20)$

Have A Brainly Day :)

0.55 as a fraction in its simplest form is 55/100.

What is a fraction?

A fraction is a representation that has a denominator and numerator as its main constituent. The expression, 0.55 can be expressed as a fraction by putting 55 as the numerator and 100 as the denominator.

If we are to simplify this further, we would have;

55/100

Divide by 5

= 11/20

At this point, the fraction cannot be simplified further.
