Given ABC = FGE find m

Answer:

None of the given points lies on the circle.

Step-by-step explanation:

The circle is represented by the following formula:

(x - xc)² + (y - yc)² = r²

Where (xc,yc) are the coordinates of the center and r is the radius of the circle. In the case we have:

(x+5)² + (y-9)² = 82

If a point belongs to this circumference, then the results of applying the points to the equation should be valid. To test all the points we are going to apply each to the equation as shown below:

A.

(0 + 5)² + (8-9)² = 82

5² + (-1)² = 82

25 + 1 = 82

26 = 82 (invalid)

The point does not lies on the circle.

B.

(13 + 5)² + (-9-9)² = 82

(18)² + (-18)² = 82

324 + 324 = 82

648 = 82 (invalid)

The point does not lies on the circle.

C.

(-5 + 5)² + (1 - 9)² = 82

0² + (-8)² = 82

64 = 82 (invalid)

The point does not lies on the circle.

D.

(3 + 5)² + (17-9)² = 82

8² + 8² = 82

64 + 64 = 82

128 = 82 (invalid)

The point does not lies on the circle.

Answer: [tex]x=-3\\y=8[/tex]

Step-by-step explanation:

[tex]3x+y=-1\\2x+3y=18[/tex]

Multiply by -3 the upper equation to make y equal in value but with opposite signs.

[tex](-3)(3x+y=-1)\\-9x-3y=3[/tex]

Now add equation 1 and 2.

[tex]-9x-3y=3\\2x+3y=18[/tex]

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

[tex]-7x=21[/tex]

Solve for x;

To isolate x, divide by -7

[tex]\frac{-7x}{-7}=\frac{21}{-7}[/tex]

[tex]x=-3[/tex]

Now use one of the equations above and replace the value of x.

[tex]3x+y=-1\\3(-3)+y=-1\\-9+y=-1\\y=-1+9\\y=8[/tex]

To prove if it's correct, take either equation and replace both x and y values, if the results are equal to each other, it is correct.

[tex]2x+3y=18\\2(-3)+3(8)=18\\-6+24=18\\18=18[/tex]

Answer:(-4,-9)

Step-by-step explanation:

Final answer:

After rotating the point (4,9) 180° about the origin, the new coordinates would be (-4, -9).

Explanation:

To determine the new coordinates of a point after a 180° rotation about the origin, you can apply the rules of rotation in a coordinate plane.

For a 180° rotation, each coordinate (x, y) becomes (-x, -y).

Therefore, if we rotate the point (4,9) 180° about the origin, we change the sign of both coordinates.

The new point after rotation would be (-4, -9).

The required probability of the selected letter was either an a or an n is 0.5.

Given that,

One letter was selected at random from the words San Antonio.  The probability that the selected letter was either an a or an n is to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total letters = 10
Total a and n = 2 and 3
The probability is given as = 2 / 10 + 3 / 10
                                            = 5/10 = 1/2 = 0.5

Thus,  the required probability of the selected letter was either an a or an n is 0.5.

Answer:

Step-by-step explanation:

the dependent variable is the amount of time she spends driving around.

Final answer:

In the scenario, the independent variable is the amount of gasoline used, and the dependent variable is the distance traveled. The domain is 0 to 2.5 gallons and the range is 0 to 162.5 miles, hence statement 2 is false regarding the dependent variable.

Explanation:

For the given situation, the independent variable is the amount of gasoline she'll use. This is because it is the variable that can be changed freely and does not depend on the other variables in the situation. In contrast, the dependent variable is the distance that can be traveled with the scooter, as it depends on the amount of gasoline used.

The domain for this situation would be the amount of gasoline available for use, which is between 0 gallons (an empty tank) and 2.5 gallons (a full tank). The range would be the distance the scooter can travel on that gasoline, from 0 miles (no gasoline) to 162.5 miles (2.5 gallons at 65 miles per gallon).

Therefore, statement 2 "The dependent variable is how many hours she will spend shopping in the stores" would have to be false given the situation and its parameters, because the dependent variable is actually the distance that can be traveled, not the time spent shopping.

Final answer:

The circumference of a circle with a given radius can be calculated using the linear equation C = 6.3r. Two examples of solutions to this equation are C = 12.6 units when r = 2, and C = 31.5 units when r = 5.

Explanation:

The circumference of a circle with a radius of r units is given by the linear equation C = 6.3r. To find two solutions of this function, we can substitute different values for r into the equation.

For example, if we let r = 2, then the circumference C is calculated as C = 6.3 * 2 = 12.6 units.

Another solution is when r = 5. In this case, the circumference C is C = 6.3 * 5 = 31.5 units.

Answer: Diameter = 7.06 cm

Step-by-step explanation:

The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Where

h represents the height of the cone

r represents the radius of the cone

π is a constant whose value is 3.14

From the information given

Volume = 157 cubic centimeters

Height = 12cm

Therefore,

157 = 1/3 × 3.14 × r² × 12

157 =12.56r²

r² = 157/12.56

r² = 12.5

Taking square root of both sides of the equation, it becomes

r = √12.5

r = 3.53 cm

Diameter = 2 × radius = 2 × 3.53

Diameter = 7.06 cm

Answer:

y = 1/4x -8

Step-by-step explanation:

First find the slope of the line

x-4y =3

Subtract x from each side

x-4y -x = -x+3

-4y = -x+3

Divide each side by -4

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

y = 1/4 x -3/4

This is in the form y= mx+b where the slope is m and the y intercept is b

The slope is 1/4

We want the same slope

y = 1/4x +b

we know the y intercept is -8

y = 1/4x -8

Answer: the sale price of one hammer is $6.8

the sale price of one nail is $0.16

Step-by-step explanation:

Let x represent the sale price of one hammer.

Let y represent the sale price of one nail.

His first customer bought 3 hammers and 16 nails for $22.96. It means that

3x + 16y = 22.96- - - - - - - - -1

His last customer bought 2 hammers and 20 nails for $16.80. It means that

2x + 20y = 16.8- - - - - - - - - 2

Multiplying equation 1 by 2 and equation 2 by 3, it becomes

6x + 32y = 45.92

6x + 60y = 50.4

Subtracting, it becomes

- 28y = - 4.48

y = - 4.48/- 28

y = 0.16

Substituting y = 0.16 into equation 2, it becomes

2x + 20 × 0.16 = 16.8

2x + 3.2 = 16.8

2x = 16.8 - 3.2

2x = 13.6

x = 13.6/2

x = 6.8

Answer:

x = 52

y = 38

Step-by-step explanation:

Angle x is supplementary to a 128º angle.

Supplementary angles add to 180

x+128 = 180

Subtract 128 from each side

x+128-128 = 180-128

x =52

Angle x and y are complementary.  

Complementary angles add to 90

x+y =90

52+y =90

Subtract 52 from each side

52-52 +y = 90-52

y = 38

Answer:

x = 52°

y = 38°

Step-by-step explanation:

x = 180 - 128

x = 52

y = 90 - 52 = 38

Answer: [tex]r=3[/tex]

Simplify both sides of the equation

[tex]r+12/5=27/5[/tex]

Subtract 12/5 from both sides

[tex]r+12/5-12/5=27/5-12/5[/tex]

[tex]r=3[/tex]

The solution to the equation 2 2/5 + r = 5 2/5 is r = 3, which is found by subtracting 2 2/5 (converted to 12/5) from 5 2/5 (converted to 27/5).

The solution to the equation 2 2/5 + r = 5 2/5 is found by isolating the variable r.

First, convert the mixed numbers to improper fractions.

We have 12/5 (equivalent to 2 2/5) and 27/5 (equivalent to 5 2/5).

Now, subtract 12/5 from both sides of the equation to get r on one side:

After subtraction, we find that:

Thus, the solution to the equation is r = 3.

Answer:

Step-by-step explanation:

The question keeps telling me to STOP!  Never mind.

The octagon is 8 isosceles triangles.  Each has common side r and base 10.  The central angle is 360/8 = 45°.  By the Law of cosines,

10² = r² + r² - 2 r² cos 45° = 2r²(1 - √2/2) = r²(2-√2)

r² = 100/(2-√2)

The area of a triangle with sides a,b and included angle C is (1/2)ab sin C. Our 8 octagon isosceles triangles each have sides r and r and included angle 45° so our total area, 8 triangles, is

A = 8(1/2) r² sin 45° = (400/(2-√2)) (√2/2) × (2+√2)/(2+√2) = 200(1+√2)

A ≈482.84271

Answer: 482.8 sq cm

Final answer:

To find the area of a regular octagon with a side length of 10 cm, use the formula: Area = 2 * (1 + √2) * side length². Substitute the given side length and round the answer to the nearest tenth.

Explanation:

To find the area of a regular octagon with a side length of 10 cm, we can use the formula:

Area = 2 * (1 + √2) * side length²

Substituting the given side length into the formula:

Area = 2 * (1 + √2) * (10)²

Area = 2 * (1 + √2) * 100

Area ≈ 414.2 cm² (rounded to the nearest tenth)

After further computation, the area approximates 414.2 cm², rounded to the nearest tenth. This formula captures the geometric intricacies of a regular octagon, demonstrating a concise method to calculate its area based on the given side length. This formula encapsulates the unique characteristics of a regular octagon, providing a streamlined approach to computing its area and showcasing the elegant relationship between side length and the polygon's spatial coverage.

Final answer:

The probability of capturing a green sea turtle considered illegal due to its size is about 45.52%. This is calculated using Z-scores and probabilities from the normal distribution, given the mean turtle size and standard deviation.

Explanation:

In the scenario provided, the probability of capturing a green sea turtle that is considered illegal (outside the 40cm to 60cm size limits) can be determined using normal distribution calculations. Given that the curved carapace length of these turtles is approximately normally distributed with a mean of 55.7 centimeters and a standard deviation of 12 cm, we will calculate the Z-scores for both size limits and then find the corresponding probabilities.

The Z-score formula is: Z = (X - μ)/σ, where X is the value in question, μ is the mean, and σ is the standard deviation. For the minimum size limit (40cm), Z = (40 - 55.7)/12 = -1.308. For the maximum size limit (60cm), Z = (60 - 55.7)/12 = 0.358.

Using standard normal distribution tables or a calculator, we find the probability corresponding to the Z-score of -1.308 and 0.358. The area to the left of Z = -1.308 is approximately 0.0951, and to the left of Z = 0.358 is approximately 0.6399. The probability of catching an illegal turtle is the sum of the probabilities of catching one smaller than 40cm and one larger than 60cm, which is P(X < 40) + P(X > 60) = 0.0951 + (1 - 0.6399) = 0.0951 + 0.3601 = 0.4552, or 45.52%.

Answer: Todd earned $40 mowing the neighbor's lawn.

Step-by-step explanation:

Let x represent the amount of money that Todd earned, mowing his neighbor's lawn.

He spent one-fourth of his money see a movie. It means that the amount spent in seeing a movie is x/4

Then he spent $6.00 on popcorn and drinks. It means that the total amount spent is

x/4 + 6

The amount left would be

x - (x/4 + 6) = x - x/4 - 6

When he went home, he had $24.00 left. It means that

x - x/4 - 6 = 24

x - x/4 = 24 + 6

x - x/4 = 30

Cross multiplying by 4, it becomes

4x - x = 120

3x = 120

x = 120/3

Answer: it will take 9 hours to empty the pool.

Step-by-step explanation:

The pool is shaped like a rectangular prism with length 30 feet, wide 18 ft, and depth 4ft. It means that when the pool is full, its volume is

30 × 18 × 4 = 2160 ft³

If water is pumped out of the pool at a rate of 216ft3 per hour, then the rate at which the water in the pool is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence(initial amount of water in the pool when completely full).

d represents the common difference(rate at which it is being pumped out)

n represents the number of terms(hours) in the sequence.

From the information given,

a = 2160 degrees

d = - 216 ft3

Tn = 0(the final volume would be zero)

We want to determine the number of terms(hours) for which Tn would be zero. Therefore,

0 = 2160 - 216 (n - 1)

2160 = 216(n - 1) = 216n + 216

216n = 2160 - 216

216n = 1944

n = 1944/216

n = 9
