The image shows two angle measures. Which equation can be used to find the
value of x?
2x - 15 = 45
2x - 15 = 135
2x - 15 + 135 = 90
2x - 15 + 131 = 360

Given:

Radius of the circle = 10 in

Central angle of the sector = 45 degrees

To find:

The area of the sector.

Solution:

Area of a sector is

[tex]A=\dfrac{\theta}{360^\circ}\pi r^2[/tex]

Where, [tex]\theta[/tex] is the central angle in degrees.

Putting r=10 and [tex]\theta=45^\circ[/tex], we get

[tex]A=\dfrac{45^\circ}{360^\circ}\pi (10)^2[/tex]

[tex]A=\dfrac{1}{8}\pi (100)[/tex]

[tex]A=12.5\pi[/tex]

Therefore, the area of the sector is 12.5π sq. inches.

Answer:

(4y/3, 0) or if there are no options, it's probably (0, 0)

Step-by-step explanation:

2x + 3y = 5x - y

So we are trying to find the missing value in the solution (_, 0)

We are looking for the x-intercept/root if the coordinate is in this way:  (_, 0)

So to find the root, We are solving for x

2x + 3y = 5x - y

First, subtract 5x from bth sides

2x + 3y - 5x = 5x - y - 5x

2x + 3y - 5x = -y

Add like terms

-3x + 3y = -y

Now, subtract 3y from both sides

-3x + 3y - 3y = -y - 3y

-3x = -4y

Divide both sides by -3

-3x/-3 = -4y/-3

x = -4y/-3

We are not done yet because the answer above is not quite right. A negative number divided by a negative number results in a positive number.

So x = 4y/3

Now that we found x, we can input it to the coordinate

(4y/3, 0)

I put it on Sesmos graphing calculator and the answer seems to be (0, 0)

Answer:

Parallel

Step-by-step explanation:

Let the required lines be y-x = 5 and y = x-1

If y-x = 5

y = x + 5

The slope m = 1

For the line y = x - 1

The slope m is also 1

Since the slope of both lines are the same, hence both liens are parallel

Answer:

-4(3v - 10)(3v + 10)

Step-by-step explanation:

You must find the factored form of 400 - 36v^2.

You can rearrange this to - 36v^2 + 400 to make it less confusing.

So you have - 36v^2 + 400.

The next step is to see what you can take out of this. You can take out a GCF, a greatest common factor. This is basically a number that goes into both 36 and 400. This number is 4.

36 / 4 = 9 and 400 / 4 = 100.

Since it is a negative 36, you need to take out a negative 4.

So you put a 4 outside parenthesis and divide - 36 / 4 and 400 / 4.

-4(9v^2 - 100).

Now you must factor the inside of the parenthesis.

9v^2 - 100.

This is the same as 9v^2 + 0v - 100.

What are 2 numbers that multiply to get -100 and add to get 0?

These numbers are -10 and +10.

2 terms that multiply together get 9v^2 are 3v and 3v.

So the answer is:

-4(3v - 10)(3v + 10).

This is the factored form.

Answer:

Margarine = 210 gram

Sugar = 180 gram

Syrup = 150 ml

Oats = 360 gram

Raisins = 75 grams

Step-by-step explanation:

Given:

Recipe for 8 flapjacks

140 g margarine

120 g sugar

100 mL syrup

240 g oats

50 g raisins

Find:

Recipe for 12 flapjacks

Computation:

Margarine = [140/8]12

Margarine = 210 gram

Sugar = [120/8]12

Sugar = 180 gram

Syrup = [100/8]12

Syrup = 150 ml

Oats = [240/8]12

Oats = 360 gram

Raisins = [50/8]12

Raisins = 75 grams

Answer:

The equation: 6 + 0.5x = 2 + 1x

How many hours till the cost is the same: 8 hours

What will the cost be: $10

Step-by-step explanation:

6 + 0.5x = 2 + 1x

subtract 0.5x from both sides

6 = 2 + 0.5x

subtract 2 from both sides

4 = 0.5x

divide both sides by 0.5

x = 8

Lets check our work:

Garage A:

6 + 0.5(8)

6 + 4 = 10

Garage B:

2 + 1(8)

2 + 8 = 10

After 8 hours the price for both garages will be equal at $10

Answer: The actual area of the base of the building = 4418 square feet.

Step-by-step explanation:

Dimensions of model: 2 inches in length and 1 inch in width.

The scale on the model is 1 inch = 47 feet.

Actual length = 2 x (47 feet) = 94 feet

Actual width = 1 x 47 feet = 47 feet

Actual area of base of building  = (Actual length) x (Actual width)

= 94 x 47 square feet

= 4418 square feet

Hence, the actual area of the base of the building = 4418 square feet.

Answer:

The three gallon container is the better buy. See below.

Step-by-step explanation:

8 pints

2 pints = 1 quart.

8 pints = 4 quarts.

4 quarts = 22.64   Divide by 4

1 quart = 5.66

3 gallons.

1 gallon = 4 quarts

3 gallons = 12 quarts.

The cost of 1 quart = 54.48/12 = 4.54

Answer:

A.21

Step-by-step explanation:

We can use trigonometry to slove for sides in this triangle...

Using the 60 degree angle...we can solve for x.

We are dealing with adjacent and opposite sides, so we use the tangent function in the calculator.

And since we're using tangent, we have to use opposite/adjacent

We have tan60=x/7sqrt3-multiply the adjacent side(7qrt3) to the other side,

and we have 7sqrt3tan60=x--enter this in to you're calculator, and you should

get an answer of 21

Answer:

Answer:

18-x=6

Step-by-step explanation:

because

if you have eighteen and some were borrowed and 6 were left so it will be subtracted

Answer:

18 - x = 6

Step-by-step explanation:

In any equation x is the unkown you are trying to figure out.

In a word-problem-solving question its helpful to set out what you know and what you dont know:

You know the original number of pens = 18

You know the final number of pens = 6

You dont know how many pens were taken.

Therefore x is the difference between 18 and 6.

18 pens take away x pens is equal to 6

hence 18 - x =6

Answer:

46

Step-by-step explanation:

180-134=46

Answer:

They're both 46 degrees

Step-by-step explanation:

Angle b and 134 are right next to each other so they're supplementary and have to equal 180 degrees.

180-134=46, and since Angle c is is a vertical angle with Angle b, it also equals 46^^

Step-by-step explanation:

Answer:

(a) Earnhardt (40%), Gordon (29%), Waltrip (18%), and Petty (13%)

(b) 144, work is below

(c) No

Step-by-step explanation:

(b)

convert 40% to a decimal by dividing by 100 = 0.4

360 x 0.4 = 144 people voted for Earnhardt

(c) converting Petty's percentage to a decimal, we get 0.13. 360 x 0.13 = 46.8, or 47 people, not 65.

Waltrip's percentage, 0.18 x 360 = 64.8, or 65 people.

60% as a decimal is 0.60

Multiply the distance by 0.60:

150 x 0.60 = 90 miles.

Answer:

90

Step-by-step explanation:

60 percent is the same as 0.6
