What is 31.55 rounded to two decimal places?

Answer:

Step-by-step explanation:

4A3-9B2

Answer:

  0.877

Step-by-step explanation:

The probability number can be found with a suitable app or calculator. A TI-83 will tell you ...

  normalcdf(-10,1.16) = 0.8769755969

The probability is about 0.877.

Answer:

One solution

Step-by-step explanation:

To start, let's simplify the equations to slope-intercept form

y - 1/4x = =1

  +1/4x     +1/4x

y           = 1/4x - 1

y - 2 = 4x

  +2          +2

y       = 4x + 2

As you can see, the equations do not have anything in common worth mentioning. The slopes are different and the y-intercepts are different, so there must be only one solution.

Answer:

Step-by-step explanation:

An engagement ring is likely very precise. The ring sizes used by some jewelers differs from the next size by 0.8 mm. As a % that's .8 / 16.5  * 100 = 4.80 %

The 0.8 is the number of mm needed to go from a size 6 to a size 7 ring size. So if you are ever going to buy a ring, be sure and let a jeweler measure the finger that it will go on.

The 16.5 mm is the diameter of the ring in mm. for a size 6 ring. If you have different information, you should go with what you have,

Size 14 dress

I can't answer this: it depends on where you live -- Europe or the US.

Also the type of dress matters: is it a skirt or a skirt and blouse combination. The % of the sides is much larger than 4% for the ring but it is still a definite description.  

Small Medium or Large

Depends entirely on where the garment is made, and where it is being sold.

Wish tells you to add a size if you live in North America. This too is not very distinct.

Answer:

(-3, 1, 2, 6, 7)

Step-by-step explanation:

coordinates work like (x,y)

range is the y values

domain is the x values

tan 47 = (side opposite the angle that is 47 degrees) / (side beside angle that is 47 degrees)

tan 47 = x/15

x = 15*tan47 = 16.09

Hope that helps!

Repost with original question.

Step-by-step explanation:

The equation given does not contain an x value and therefore cannot be solved.

Answers are in bold.

22. b/c

24. sqrt(17)/17

26. 1/4

28. sqrt(17)/17

30. 1/2

32. sqrt(2)/2

34. sqrt(3)/2

36. Approximately 5.4077 units

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

Explanation:

Problem 22

To get the cosine ratio, we divide the adjacent over hypotenuse.

cos(angle) = adjacent/hypotenuse

cos(x) = b/c

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

Problem 24

To get the sine ratio, we divide opposite over hypotenuse.

[tex]\sin\left(\text{angle}\right) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin\left(\text{x}\right) = \frac{2}{2\sqrt{17}}\\\\\sin\left(\text{x}\right) = \frac{1}{\sqrt{17}}\\\\\sin\left(\text{x}\right) = \frac{1*\sqrt{17}}{\sqrt{17}*\sqrt{17}}\\\\\sin\left(\text{x}\right) = \boldsymbol{\frac{\sqrt{17}}{17}}\\\\[/tex]

In the fourth step, I multiplied top and bottom by sqrt(17) to rationalize the denominator.

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

Problem 26

tan(angle) = opposite/adjacent

tan(x) = 2/8

tan(x) = 1/4

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

Problem 28

cos(y) = sin(x) in this case. The general rule is that sin(A) = cos(B) if and only if A+B = 90.

Therefore the answer is exactly identical to problem 24.

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

Problem 30

sin(30) = 1/2 is something you either memorize or look up on a reference chart, or use the unit circle. Alternatively, you can use a 30-60-90 triangle template.

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

Problem 32

[tex]\sin\left(45^{\circ}\right) = \boldsymbol{\frac{\sqrt{2}}{2}}\\\\[/tex] is something you memorize or have on a reference sheet. You could also use a 45-45-90 triangle.

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

Problem 34

[tex]\cos\left(30^{\circ}\right) = \boldsymbol{\frac{\sqrt{3}}{2}}\\\\[/tex] is similar to problems 30 and 32 in that you should memorize this or have it on a reference sheet. You could use a 30-60-90 triangle template here.

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

Problem 36

Let x be the length of side AC.

Use the tangent ratio to find x.

tan(angle) = opposite/adjacent

tan(B) = AC/AB

tan(31) = x/9

x = 9*tan(31)

x = 5.4077 approximately

Answer:

No

Step-by-step explanation:

Given the following question

In order to prove if three lengths can create a triangle two of the three sides added together HAS to be greater than the third side.

[tex]a+b > c[/tex]
[tex]1+10=11[/tex]
[tex]11 < 20[/tex]

Which means your answer is "no," the given sides cannot create a triangle for they do not pass the Triangle Inequality Theorem.

Hope this helps.

Solution:

We know that:

Verification:

Conclusion:

The given side lengths cannot be a triangle.

Answer:

Complementary angles

adjacent angles

Step-by-step explanation:

[tex]< 1+ < 2=90[/tex]°

⇒     complementary angles

The sum of two angles is 90° are complementary angles.

[tex]< 1[/tex] is close to [tex]< 2[/tex]

⇒     adjacent angles

I hope this helps you:)

Answer: 78 eggs

Step-by-step explanation:

We can set up a ratio.

Let x be the amount of eggs in 13 cartons.

Then, [tex]\frac{1 carton}{6 eggs} = \frac{13 cartons}{x eggs}[/tex]

Now we can cross multiply and we get x = 78 eggs

The total number of eggs in the 13 cartons is 78.

Given the parameters:

Number of eggs in one carton = 6 eggs

Number of cartons = 13

Total number of eggs in 13 cartons =?

To determine the total number of eggs in 13 cartons, you simply multiply the number of eggs per carton (6) by the number of cartons (13).

Using the multiplication method:

Total number of eggs = Number of eggs in one carton × Number of cartons

Plug in the values:

Total number of eggs = 6 eggs/carton × 13 cartons

Total number of eggs = 6 eggs × 13

Total number of eggs = 78 eggs

Therefore, the total number of eggs is 78.

Answer:

3(2v - 3)(3v + 2)

Step-by-step explanation:

18v² - 15v - 18 ← factor out 3 from each term

= 3(6v² - 5v - 6) ← factor the quadratic

consider the factors of the product of the coefficient of the v² term and the constant term which sum to give the coefficient of the v- term.

product = 6 × - 6 = - 36 and sum = - 5

the factors are - 9 and + 4

use these factors to split the v- term

6v² - 9v + 4v - 6 ( factor the first/second and third/fourth terms )

= 3v(2v - 3) + 2(2v - 3) ← factor out (2v - 3) from each term

= (2v - 3)(3v + 2)

Then

18v² - 15v - 18 = 3(2v - 3)(3v + 2)

Answer:

210

Step-by-step explanation:

The mean=210

When your doing mean next time this is how you do it. you add up all the numbers so 210 225 206 214 180 and 225. The you divide by the total of numbers so there are a total of 6 numbers.

When you add up all these numbers it has a total amount of 1,260.

so what is 1,260 divided by 6? It=210.

Would you like to also know mode median and range.

Median=212
When you do median you sort the list of numbers least to greatest and the middle number is median now since there are an even amount of numbers you would use 3 and 4 since were on 6 and do the middle between them 2 so 210 and 214.

The middle number between them is 212 and that's your answer,

Mode=All the numbers above and for the list of numbers here,all the numbers appear the same amount of times because dealing with mode,mode is the number or numbers that appears most in the data set,and for this one they all appear once.

Range=45

Range is the highest number-the lowest number so 225-180=45.

Minimum is 180 because minimum is the lowest number in the data set.

Maximum is 225 because maximum is the highest number in the data set.

Hope it helps have a great day:)

Answer:

324pi

Step-by-step explanation:

V of sphere = 4/3 x pi x r^3

V of cone = pi x r^2 x h x 1/3

4/3 x pi x 6^3 = 288 pi

pi x 6^2 x 15 x 1/3 = 180 pi

since the sphere is cut in half = 288/2 = 144

144 pi + 180 pi = 324 pi

Answer:

label a graph doing -5,-8, and 4,4  use the formula which is

d = ( x 2 − x 1 )^2 + ( y 2 − y 1 )^2

 x2-x1 = 4–2= 2 Y2–Y1 = 1–3 = -2 d=√(2)^2+(-2)^2 =√4+4 = √8 d= 2√2

8 tons = 16000 pounds

conversion:

1 tons ➟ 2000 pounds

8 tons ➟ (2000 * 8) pounds

8 tons ➟ 16000 pounds   ⚡⚡

The amount 8 tons in pounds can be written as 16, 000 pounds.

To convert 8 tons to pounds,

we need to know that 1 ton is equal to 2,000 pounds.

We know that when a smaller unit converted to big unit then we have to multiply.

So, the conversion of 8 tons to pounds

= 8 tons x 2,000 pounds/ton

= 16,000 pounds

Thus, the amount 8 tons in pounds can be written as 16, 000 pounds.
