Work out 69% of 102.16m
Give your answer rounded to two Decimal Place

Answers

Answer:

70.49

Step-by-step explanation:

Finding the percent of a number is the same as multiplying the number by the percent in decimal form. In other words, diving the percent by (100) and then multiplying the reuslt by the number one wants to find the percent of.

69% of 102.16

= (69 / 100) * 102.16

= 0.69 * 102.16

= 70.4914

Finish solving the equation -13y + 33 = 7.

Answers

Answer:

y = 2

Step-by-step explanation:

-13y + 33 = 7

add -13y to each side of the equation:

33 = 13y + 7

subtract 7 from each side:

13y = 26

divide both sides by 13:

y = 2

-13y + 33 = 7
-13y = 40
y = -3.0769

Find the measure of the indicated angle to the nearest degree

Answers

Answer:

A) 18°

Step-by-step explanation:

To find the measure of the indicated angle, we can use trigonometric ratios.

Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:

[tex]tan(?)=\frac{opposite}{adjacent}[/tex]

From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:

[tex]tan(?)=\frac{3}{9}[/tex]

Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:

[tex]?=tan^{-1}(\frac{3}{9})[/tex]

And we get:

? ≈ 18.4349488° ≈ 18°

So the answer would be 18°, or A.

I hope you find my answer to be helpful. Happy studying.

Answer:89

The value of x is 9.4 units in the given right triangle, which is determined by   Pythagoras's theorem.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The triangle is given in the form of a right-angled triangle

According to Pythagoras's theorem,

The formula is a² + b² = c²

Here a = 8, b = 5, and c = x

Substitute the values in the above formula,

⇒ 8² + 5² =  x²

⇒ 64 + 25 = x²

⇒ 89 = x²

⇒ x² = 89

⇒ x = √89

⇒ x = 9.433

Rounded nearest tenth

⇒ x = 9.4

Therefore, the value of x is 9.4 units in the given right triangle.

Here, we want to arrange 8 flags in a row

In the row, there will be 8 places

The first place has 8 flags to be chosen from

The second place has 7 and like that

So mathematically, the number of ways that we can arrange the flags is 8 factorial ways

We have this as:

Answers

Answer:

12.12 feets

Step-by-step explanation:

Based on the attached diagram, we can apply trigonometric rule to obtain h :

Sinθ = opposite / hypotenus

Opposite = h

Hypotenus = 14

Sin 60 = h / 14

0.8660254 = h / 14

h = 0.8660254 * 14

Height, h = 12.12 feets

There are plenty of reasons why movies are better than books.First, books are things that you can only enjoy alone. Movies are different. Whether you get together at a theater or have a movie night at a friends house, movies are a social activity. No one ever said: Hey, lets hang out and read a book tonight! Movies are better than books because they bring people together.Next, books take too long to read. Some books are short, but many books can be hundreds of pages long. In contrast, most movies are only two hours long. You can enjoy a movie in a single afternoon. You could even enjoy two or three! But some books can take weeks or even months to read.Finally, books are just plain less exciting. Movies have special effects, dramatic music, and talented actors who bring the story to life. Books, on the other hand, usually just have words! What is more exciting, reading a tedious description of a high-speed car chase, or actually getting to see one?Books may have more detail and let you use your imagination more, but movies are way more fun and enjoyable. In my opinion, movies are far superior to books.No sources were consulted in the composition of this passage.According to paragraph 3, it takes about two hours toAwatch a movieBwatch two or three moviesCread a bookDread two or three books PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!!

But in a country like South Africa, it was almost impossible for a man of my birth and color to fulfill both of those obligations. In South Africa, a man of color who attempted to live as a human being was punished and isolated.
