PLZ HELP I REWARD BRAINLIEST PLZ!!

Answer:

Option A.

Step-by-step explanation:

A rational number is a number that can be expressed in a fraction (ratio of integers).

Option A is rational since both quantity are rational

Option B is irrational since

[tex]\sqrt{3}\cdot\sqrt{9}=\sqrt{27}[/tex]

where 27 is not a square of any fractions/ integers. Hence, it cannot be expressed as a fraction and is irrational.

Option C is irrational. Note that PI is irrational. Any rational multiples of an irrational number must also be irrational.

Option D is irrational. Similar to Option B.

Answer:  1  1/2

You can write this as 1 & 1/2

The whole part is 1. The fractional part is 1/2

==========================================================

Explanation:

Let's say we had 18 cookies to hand out to 12 students.

How many cookies does each student get?

Using a calculator shows that 18/12 = 1.5 which means they get one whole cookie each

The leftovers is 18-12 = 6

Then notice how 6/12 = 1/2

So that's how the improper fraction 18/12 becomes the mixed number 1 & 1/2

So each student gets 1 full cookie, plus half a cookie.

------------------

Or we could do the problem like this

18/12 = (12+6)/12

18/12 = (12/12)+(6/12)

18/12 = 1 + (1/2)

18/12 = 1 & 1/2

4 - 5|6 - 3(8 - 2)|

4 - 5|6 - 3 × 6|

4 - 5|6 - 18|

4 - 5|-12|

4 - 5 × 12

4 - 60

Answer:

P= -80

Step-by-step explanation:

Make bring p to the other side

.60p-p=32

-.4p=32

p= -32/.4

p=-80

P= -80 Is the final answer

Answer:

They are actually 53.9 miles away.

Step-by-step explanation:

1 in = 15.4 mi

Set up an equation:

Variable x = number of miles

1/15.4 = 3.5/x

Cross multiply:

1 × x = 15.4 × 3.5

x = 53.9

Answer:

x=6

Answer:

Step-by-step explanation:

This is one of those things that will drive you insane until you understand the answer.

Every y value is 4 no matter what x is.

The perpendicular will meet y = 4 at the point (6,4)

Answer: So the equation has to be x = 6.

The blue line is y = 4

The red line is x = 6

The point of intersection is marked.

the correct answer is false

Answer:

76

Step-by-step explanation:

Firstly I called the original number 'y'

Then i formulated an equation by adding in the processes mentioned in the question: (y + 14) x 2/3 = 60

Then i solved the equation

First I multiplied (y + 14) by 2/3: (y + 14) x 2/3 = (2/3 x y) + (14 x 2/3) = 2y/3 + 28/3

I simplified that to 2y + 28/3 = 60 since you can add fractions which have the same denominator

Then to get rid of the fraction i multiplied both sides by 3 to get 2y + 28 = 180

Then i took away 28 from both sides to get 2y = 152

Then i divided both sides by 2 to get 'y'(the original number) on its on: y = 76

Answer:

Step-by-step explanation:

All the reasons are correct apart from the 4th.

Step 4 involves multiplication of both sides by (2/3). Thee reason given is: "Division property of equality", which is wrong as division is not applicable.

Answer:

Reason 4 is correct I just did the quiz

Answer:

these both are the same equations

Answer:

[tex] {( - 2a)}^{5} [/tex]

open the bracket:

[tex] = ( - 2) {}^{5} (a) {}^{5} \\ \\ = - 32 {a}^{5} [/tex]

magnitude:

[tex] | - 32 {a}^{5} | = 32 {a}^{5} [/tex]

Answer:

-32a**5

Step-by-step explanation:

any negative to an odd power is negative

(-2a)**5 = (-2**5 * a**5) = -32a**5

Answer:

I think the correct answer to this, (if I'm not wrong), would be D.

Answer:

p = -1.66

Step-by-step explanation:

-3p = p - 1 - (p - 6)

-3p = p - 1 - p + 6

-3p = 5

p = 5/-3

p = -1.66

Answer:

$4.70 + $4.75m = $18.95 which is 3 miles in total.

Step-by-step explanation:

First make the numbers without the variables on one side.

4.75m = 18.95-4.70

Then subtract.

4.75m = 14.25

Finally divide the two numbers.

14.25 ÷ 4.75 = 3 miles

Answer:  m = 3  or 3 miles

Answer:

3 miles

Step-by-step explanation:

Pick up fee = $4.70

Charge = $4.75 per mile therefore this is expressed as 4.75 x m (or 4.75m)

18.95 = 4.7 + 4.75m (add the pick up fee plus fare per mile)

Subtract 4.7 from both sides then divide 4.75 from both sides.

This leaves you with m = 3

Answer:

give brainliest please I need it to level up

Step-by-step explanation:

the gcf of 13 and 65 is 13

13 + 65 can be rewritten using the gcf as

13( 1 + 5)

The greatest common factor of 13 and 65 is 13.

The 13 + 65 could be written using the gcf as 13(1 + 5).

Given that,

Based on the above information, the calculation is as follows:

The GCF is 13

And, it could be rewritten as 13(1 + 5).

Step-by-step explanation:

#1

Length = Area/Width

Length = 5673/61

Length = 91 m

#2

Perimeter = 2(l + w)

292 = 2(88 + w)

292/2 = 88 + w

146 = 88 + w

146 - 88 = w

58 = w

Answer: Radius is 3 ft

Step-by-step explanation:

Formular:

[tex]{ \boxed{V = \frac{4}{3} \pi {r}^{3} }} \\ [/tex]

substitute:

[tex]36\pi = \frac{4}{3} \pi {r}^{3} [/tex]

multiply all sides by 3:

[tex](36\pi \times 3) = ( \frac{4}{3} \pi {r}^{3} ) \times 3 \\ \\ 108\pi = 4\pi {r}^{3} [/tex]

divide all sides by π :

[tex] \frac{108\pi}{\pi} = \frac{4\pi {r}^{3} }{\pi} \\ \\ 108 = 4 {r}^{3} [/tex]

divide all sides by 4:

[tex] \frac{108}{4} = \frac{4 {r}^{3} }{4} \\ \\ {r}^{3} = 27[/tex]

take a cube root:

[tex] \sqrt[3]{ {r}^{3} } = \sqrt[3]{27} \\ r = \sqrt[3]{(3 \times 3 \times 3)} \\ r = \sqrt[3]{ {3}^{3} } \\ \\ r = 3[/tex]
