Answer:

0 percent

Step-by-step explanation:

it is a good question

in the question only there is written that he took *3 marbles*

Answer:

1 = 3

2 = 6

3 = 9

Step-by-step explanation:

for every # it is multiplied by 3 (ex. 7 • 3 = 21, 8 • 3 = 24, ect.)

therefore if it is multiplied by 3 each time

then 1 • 3 = 3

2 • 3 = 6

and 3 • 3 = 9

Answer:

Step-by-step explanation:

The measure of arc mFD in the above figure is 130°.

The arc of a circle is a portion of the circumference of that circle. It's outlined as a continuous curve that connects two points on the circle. The two endpoints of the arc are known as the arc's endpoints, while the center of the circle is appertained to as the arc's center.

The extent of an arc is directly proportional to the size of the angle it subtends at the center of the circle. However, the arc will be longer, and if the angle is inferior, If the angle subtended is substantial.

From the figure, it is evident that ∠AOC = 90° and ∠AOB = 140°.

As it is known that the whole angle is 360°.

So,

∠AOB + ∠AOC + ∠BOC = 360°

140° + 90° + ∠BOC = 360°

∠BOC = 360° - 140° - 90°

∠BOC = 360° - 230°

∠BOC = 130°

So,

mBC = 130°

Also, as evident from the figure,

mFD = mBC

So,

mFD = 130°.

Therefore, the measure of arc mFD is 130°.

Answer:

49.47 m

Step-by-step explanation:

You will need to use the cosine function

which is the ratio adjacent side/hypotenuse

So, let x = length of guy wire

then   cos 14 = 48/x

         x cos 14 = 48

             x = 48/cos 14

                = 49.47 m

Note:  You must memorize the definitions of all the trig functions so you can do problems like this one.  OK?

Answer:

X= 6.4   ∠A=68.8

Step-by-step explanation:

We know that these 2 angle must equal 180 so we use the equation:

180=7x+24+3x+92

OR

180=7x+3x+24+92

Then, we add like terms (both variable and numbers)

180=10x+116

After that, we solve

180=10x+116

-116        -116

__________

64=10x

________

64/10 = x

________

6.4=x

Now that we have found x, we can plug in x to figure out the new equation to find the angle of A (or B).

∠A= 7(6.4)+24

If we solve that, it would be:

∠A=44.8+24

___________

∠A=68.8

Answer:

x= 154°

Step-by-step explanation:

since the interior angle sum of a triangle is 180°, we can subtract the interior angles we already have from 180°

so, 180-108-46= 26° which gives us our missing interior angle.

then, we see the straight line is 180° where we need x.

so, we subtract 26 from 180 which leaves us with 154.

therefore, x= 154°

Answer: 28

Step-by-step explanation:

Let the number of balloons that she had last party be represented by x.

Since Mrs.Hines has 40 ballons for a party which was 12 more balloons than she had for her last party. The number of ballons had last party will be formed into an equation as:

x + 12 = 40

Collect like terms

x = 40 - 12

x = 28

She had 28 balloons last year

Answer:

A shows the equation y = -3x

Answer:

1.25π

Step-by-step explanation:

Hello There!

The area of a sector can be found using this formula

[tex]A=\frac{0}{360} \pi r^{2}[/tex]

where 0 = angle and r = radius

so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula

so...

[tex]A=\frac{50}{360} \pi 3^{2} \\3^{2}=9 \\\frac{50}{360} 9=1.25[/tex]

so the area of the sector = 1.25π

Note: it says to leave your answer in terms of pi so we do not have to apply pi

Answer: 4311/9900 or 479/1100

Step-by-step explanation:

Okie so in order to do this, we need to get rid of the repeating part of the decimal

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

Right now we have x = 0.435454545454...

If we multiply this by 100, we get

100x = 43.545454545454

And if we multiply by 10000 we get

10000x = 4354.5454545454

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

Subtract the two equations

10000x = 4354.5454545454

100x = 43.545454545454

------------------------------------------------- (notice: the repeating part will cancel out)

9900x = 4311

x = 4311/9900

If you simplify the fraction you get: 479/1100

The fraction that represents the repeating decimal is

[tex]\frac{479}{1100}[/tex]

Given :

A repeating decimal  [tex]0.4354545454...............[/tex]

there is bar at 54 , so 54 is repeating

We need to convert this decimal into fraction

54 is repeating so we multiply by 100

Let x= [tex]0.4354545454...............\\[/tex]

[tex]100x=43.54545454...............[/tex]

Now we subtract x from 100x

[tex]100x=43.54545454...............\\ x= 0.4354545454...............\\-----------------------------------------\\ 99x=43.11[/tex]

Now divide both side by 99

[tex]x=\frac{43.11}{99} \\[/tex]

multiply top and bottom by 100 to remove the decimal

[tex]x=\frac{4311}{9900} \\Divide \; top \; and \; bottom \; by 9\\x=\frac{479}{1100}[/tex]
