Answer:

Yes they are wrong, rational & irrational ones down below.

Step-by-step explanation:

So, lets start this by asking, what is a rational and irrational number?

Rational numbers are literally any numbers that arent pi, e, or other symbols, as well as square roots.

Irrational numbers are exactly the opposite, being the numbers that are symbols, including square roots.

Note that the symbols listed above such as pi are values that are neverending.

Now, using what we know of rational and irrational numbers, let see which answers are rational and which are not.

So, we start off with:

-13/3

I do not see a square root.

I do not see a symbol such as pi either.

It is not a ever going number.(number that continues infinitly)

So -13/3 is a rational number.

Next we have [tex]\sqrt{37}[/tex]

immediatly we tell it has a square root.

So [tex]\sqrt{37}[/tex] is a irrational number.

Next we have 0.1234

This is not a every going number.

There isnt a square root.

And it isnt a symbol.

So 0.1234 is a rational number.

Next we have [tex]-\sqrt{100}[/tex]

Again, we can immediatly know it has a square root.

So  [tex]-\sqrt{100}[/tex] is a irrational number.

Next we have -77

This is not every going.

It doesnt have a square root.

It doesnt have a symbol.

So -77 is a rational number.

Lastly we have   [tex]-\sqrt{12}[/tex]

Like the other ones, we can imediatly tell it has a square root.

So [tex]-\sqrt{12}[/tex] is a irrational number.

Bascially, to answer further questions, here is the criteria for a number being rational:

If one of these criterias are not met, then you know its a irrational number.

I'm not that sure but I think the answer is Median (A)

Answer:

16. r = 20, t = 48

17. a = 104, b = 175

19. 144/252, 20/35

20. 14/21, 18/27

21. 16/48, 12/36

22. 219 grams

23. 5 milligrams

Step-by-step explanation:

Answer:

16. r = 20

     t = 48

17. a = 104

    b = 175

19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]

     7.2 = 7.2

20. [tex]\frac{27}{18}= \frac{21}{14}[/tex]

     1.5 = 1.5

21. [tex]\frac{48}{16} =\frac{36}{12}[/tex]

     3 = 3

22. [tex]\frac{8}{3} :\frac{584}{y}[/tex]

     219 grams of peanuts

23. [tex]\frac{y}{2}: \frac{200}{80}[/tex]

     50 milligrams of medication

Step-by-step explanation:

16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]

8 · 4 = 32

5 · 4 = 20

r = 20

5 · 6 = 30

8 · 6 = 48

t = 48

17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]

Here is a different method.

[tex]\frac{10}{20} =\frac{1}{2}[/tex]

52 · 2 = 104

a = 104

350 ÷ 2 = 175

b = 175

22.

[tex]\frac{8}{3} :\frac{584}{y}[/tex]

8 · y = 3 · 584

8y = 1752

8y ÷ 8 = 1752 ÷ 8

y = 219

23.

[tex]\frac{y}{2}: \frac{200}{80}[/tex]

y · 80 = 200 · 20

80y = 4000

80y ÷ 80 = 4000 ÷ 80

y = 50

Answer: c

Step-by-step explanation:

The area of pentagon ABCDE is 36 times the area of pentagon PQRST. Therefore, the option C is the correct answer.

Any five-sided polygon or 5-gon is referred to as a pentagon. A basic pentagon's interior angles add up to 540°. A pentagon might be straightforward or self-intersecting.

We know the formula for the area of a pentagon, therefore, the area of the pentagon PQRST can be written as,

A= 1/4 ×√(5(5+25)×a²

Given that the side of the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, therefore, the area of the pentagon ABCDE can be written as,

Area of a ABCDE = 1/4 ×√(5(5+25)×(6a)²

= 1/4 ×√(5(5+25)×36a²

= 36A

Therefore, the option C is the correct answer.

Answer:

w=129.8

Step-by-step explanation:

w + 125.2 = 255​

                  -125.2

w=225-125.2

w=129.8

Answer:

Hope this helps please mark me as branlist.

Step-by-step explanation:

Subtract 125.2 from both sides:

w=125.2=255

w=125.2-125.2=255-125.2

w=255-125.2

w=129.8

An octagon has eight sides while the shape on the right has nine sides.

Answer:

No

Step-by-step explanation:

The shape shown in the picture has 9 sides(you can count) and therefore is not an octagon because octagons only have 8 sides.

Answer: 1) Using the order of operations, you first have to multiply the amount of each item by it's price, and then add those values. So for Pablo, you would do (0.50 x 1) + (0.75 x 3) + (1.25 x 3) and solve within the parentheses to get .50+2.25+3.75=$6.50

2) For Laurie, use the same method from #1. First multiply and then add, like so: (0.5 x 2) + (1.25 x 3) + (0.75 x 3) ---> 1+3.75+2.25, which equals $7

3) Laurie > Pablo

   $7.00 > $6.50

Step-by-step explanation:

The term order of operations is also known as PEMDAS

Answer:

8.40

Step-by-step explanation: This means the cost of the item to you is $8.4. You will pay $8.4 for a item with original price of $12 when discounted 30%. In this example, if you buy an item at $12 with 30% discount, you will pay 12 - 3.6 = 8.4 dollars.

Answer:

The new total will be $8.40.

Step-by-step explanation:

The 30% off discount gives you $3.60 off of your purchase.

Answer:

x = 34

Step-by-step explanation:

Given

x + 38 = 72 ( subtract 38 from both sides )

x = 34

Answer:

X=34

Step-by-step explanation:

Well, what you can do is bring the 38 to the other side and make it negative so you can subtract 38 with the 72. The 72-38 is= 34 and so x= 34

x+38=72

x=72-38

x=34

Answer:

73.5

Step-by-step explanation:

Please find the complete question in the attached image

Remember the notation SOHCAHTOA

We would be using cos because we have been given the hypotenuse and we are to determine the adjacent value

cos 37 = adjacent / hypotenuse

cos 37 = adjacent / 92

0.7986 = adjacent / 92

adjacent = 0.7986 x 92 = 73.5

Answer:

Respuesta. el resultado (17) va ser el numerdaor de la fraccion y el denominador se mantiene.

Step-by-step explanation:

Answer:

Company one charges $11 + $0.16 per min.

Then if you talk for x minutes, the cost will be:

C₁(x) = $11 + ($0.16 per min)*x

For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:

C₂(x) = $20 + ($0.11 per min)*x

Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.

C₁(x) = C₂(x)

$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x

($0.16 per min)*x - ($0.11 per min)*x = $20 - $11

($0.05 per min)*x = $9

x = $9/($0.05 per min) = 180 mins

If you speak for 180 minutes, the cost is the same in both companies.
