least to greatest 11/20,1/2,0.51

Answers

Answer:

1/2, 0.51, 11/20

Step-by-step explanation:

11/20 = 0.55

1/2 = 0.50

0.51

Least to greatest ---> 1/2, 0.51, 11/20

Answer:

1/2, 0.51, 11/20

Step-by-step explanation:

To find out which one is least to greatest, I suggest turning all the numbers into decimals. In order to do this you need to divide the 11 by 20 on a calculator which equals 0.55. Then, we already know that 1/2 = 0.50, and that leaves us with 0.51. So, know we order them.

Vicci designed a square tile in art class. Each corner of the square tile has a measure of 90 degrees.
Which equation could be used to find the measure of Angle x?

Answers

Answer:

360-270=x

x=90 degrees

Step-by-step explanation:

There are two ways i know of how you can do this

The first way:

Ok so lets add up all the angles we know

90+90+90=270

Now we subtract that from 360

360-270=90

And there we have it the measure of angle x is 90 degrees

The second way:

Ok lets name all the angles we know. Hypothetically we only know that one angle is 90.

measure of angle one is 90 degrees

So now we subtract that from 360

360-90=270

Now we divide that by three because there are only 4 angles and we know the measure of one of the angles

270/3=90

And there we have it the measure of angle x is 90 degrees

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.

1/4x = -10
x = -40

Answers

Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4

His mistake is that he does not open the bracket first. The value of the x is negative of 4.

What is a BODMAS rule?

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2.

First, open the bracket, then we have

$\dfrac{x}{4} + \dfrac{12}{4} = 2$

On simplifying, we have

$\dfrac{x}{4 } + 3 = 2$

Subtract 3 from both sides, we have

$\dfrac{x}{4} = -1$

Multiply the equation by 4, we have

$x = -4$

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
$\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}$
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
$\hrulefill$
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
