solve 1/2 - 6/8 equals to 2​

The reasons for the statements supporting the proof that ∡TV ≅ ∡ XW are given as follows;

A - Given

H - Vertical Angles

F- Angles that inscribe a half circle are congruent and 90°

C - Angle-Angle-Side Triangle Congruence

E - CPCTC

D - Reflexive Property

I - Hypotenuse Leg (H-L) Triangle Congruence

G - CPCTC

B - Arcs of a congruent angles are congruent

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent". It is a theorem used in geometry to prove that two triangles are congruent.

An inscribed angle is half the measure of its intercepted arc. A half circle is a semicircle, which has an intercepted arc of 180°, so the inscribed angles are 1/2(180°) = 90° and congruent.

The reflexive property is a property of equality that states that any quantity is equal to itself. In other words, a = a. This property is used in many mathematical proofs.


The Hypotenuse-Leg (H-L) Triangle Congruence is a rule used to prove that two right triangles are congruent. If the hypotenuse and a leg of one triangle are congruent to the hypotenuse and the corresponding leg of another triangle, then the two triangles are congruent.

The set of sample means generated by Mark may not be representative of the population of the city.

This is because Mark's sampling method is not random and may introduce bias into the sample. By only surveying bypassers in the central street, the sample may not be representative of the whole population of the city. On the other hand, Judy's random sampling method has a higher chance of capturing a representative sample of the population.

To confirm this, we can compare the sampling distributions generated by both methods. We can calculate the mean and standard deviation of the sample means for each method and compare them. If the means and standard deviations are significantly different, it may suggest that Mark's sampling method is biased.

To calculate the standard deviation of the sampling distribution, we can use the formula:

Since the population standard deviation is not given, we can use the sample standard deviation as an estimate. Assuming the sample standard deviation is 2, we can calculate the standard deviation of the sampling distribution as follows:

For Judy's method:

For Mark's method:

Assuming that the central street has a population size of 1000, we can calculate the standard deviation as:

Answer:

40 and 27

Step-by-step explanation:

Answer:Let's call the two numbers x and y.

From the problem, we know that:

x + y = 67 (equation 1)

and

x - y = 13 (equation 2)

To solve for x and y, we can use the method of elimination. We can add equations 1 and 2 to eliminate y:

(x + y) + (x - y) = 67 + 13

Simplifying this equation, we get:

2x = 80

Dividing both sides by 2, we get:

x = 40

Now we can use equation 1 to solve for y:

x + y = 67

40 + y = 67

Subtracting 40 from both sides, we get:

y = 27

Therefore, the two numbers are 40 and 27.

Step-by-step explanation:

To determine whether the ice cream scoop will fit in the cone or overflow, we need to compare the volume of the scoop to the volume of the cone. If the volume of the scoop is less than or equal to the volume of the cone, the scoop will fit in the cone. If the volume of the scoop is greater than the volume of the cone, the scoop will overflow.

The formula for the volume of a sphere is:

V_sphere = (4/3)πr³

where r is the radius of the sphere. In this case, the radius of the ice cream scoop is 3 cm, so:

V_sphere = (4/3)π(3 cm)³ ≈ 113.1 cm³

The formula for the volume of a cone is:

V_cone = (1/3)πr²h

where r is the radius of the base of the cone and h is the height of the cone. In this case, the radius of the cone is also 3 cm and the height of the cone is 5 cm, so:

V_cone = (1/3)π(3 cm)²(5 cm) ≈ 47.1 cm³

Therefore, the volume of the ice cream scoop is greater than the volume of the cone, and the ice cream will overflow when it melts.

To explain this result, we can note that the volume of the ice cream scoop is determined by its shape and size, which cannot be changed. However, the volume of the cone is determined by both its shape and size, as well as the amount of space available inside it. When the ice cream melts, it will fill up the cone and displace the air inside, increasing the volume of the cone. However, the volume of the ice cream scoop will not change, so it will overflow the cone.

The volume of the right circular cone is approximately 1819.1 cubic centimeters.

Volume is the measure of the amount of space occupied by a three-dimensional object or shape. It is expressed in cubic units, such as cubic centimeters, cubic meters, or cubic inches, depending on the system of measurement being used. The formula for volume varies depending on the shape of the object, but for many common three-dimensional shapes, such as cubes, spheres, cylinders, and cones, there are well-known formulas for calculating their volumes.

According to the given information :

The formula for the volume of a right circular cone is V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone.

Substituting the given values, we get:

V = (1/3)π(9.6 cm)²(19.9 cm)

V ≈ 1819.1 cubic centimeters (rounded to the nearest tenth)

Therefore, the volume of the right circular cone is approximately 1819.1 cubic centimeters.

Answer:

1.)  51.515%  2.) 48.485%

Step-by-step explanation:

In this question we know 66 is 100% of the fraction, so we can start the process of converting a fraction into a percent, by figuring out how to adjust the fraction so that the denominator will be 100. First, divide 100 by the denominator.

100/66 = 1.515

Now we want to multiply denominator and numerator by 100.

34 × 1.515 = 51.515

66 × 1.515 = 100

Therefore, 34/66 as a percentage will be 51.515%

Now we want to convert 32/66. We will do the same for this equation.

100/66 = 1.515

32 × 1.515 = 48.485

66 × 1.515 = 100

Therefore 32/66 as a percentage will be 48.485

Therefore the total cost for 18 months of membership is[tex]$742.50[/tex].The equation to find the cost of initiation and x months of membership is y + 59x = 742.50

The equation to find the cost of initiation and x months of membership is y + 59x = 742.50. Since the cost for one year of membership is known, the cost for initiation can be found by subtracting 59x from both sides of the equation, resulting in y = 742.50 - 59x. To find the total cost for 18 months of membership, we plug x = 18 into the equation, resulting in y + 59(18) = 742.50. This can be simplified to y + 1062 = 742.50, which means that y = -319.50. Therefore, the total cost for 18 months of membership is[tex]$742.50 - $319.50[/tex], which equals [tex]$423.00[/tex]. This calculation can be represented by the equation y + 59x = 742.50, where y is the cost of initiation and x is the number of months of membership. Plugging in the number of months of membership (x = 18) gives us the total cost for 18 months of membership (y + 1062 = 742.50). Simplifying this equation yields y = -319.50, and therefore the total cost for 18 months of membership is[tex]$742.50.[/tex]

Answer:

To find out which expression must be added to 3x - 7 to equal 0, we need to solve the equation:

3x - 7 + a = 0

where "a" is the expression to be added.

To solve for "a", we can isolate "a" on one side of the equation by adding 7 to both sides:

3x - 7 + a + 7 = 0 + 7

Simplifying the left side, we get:

3x + a = 7

Therefore, the expression that must be added to 3x - 7 to equal 0 is:

a = -3x + 7

We can check that this is correct by substituting -3x + 7 for "a" in the original equation:

3x - 7 + (-3x + 7) = 0

Simplifying the left side, we get:

3x - 3x - 7 + 7 = 0

0 = 0

The equation is true, which confirms that the expression -3x + 7 must be added to 3x - 7 to equal 0.

The minimum value of the function is 9, and the function never stops increasing.

The given function is y=(x−9)²+9.

We need to find the minimum and maximum value of the function. The given function is a quadratic function whose graph is a parabola. Since the coefficient of x² is positive, the graph of the quadratic function will be in the form of an upward parabola whose vertex is at the point (h,k).

The vertex form of the quadratic function is given byy = a(x - h)² + k, where(h,k) is the vertex of the parabola.

a is the coefficient of (x - h)².

In the given function,y = (x-9)² + 9, the vertex of this function is (9,9) and a=1.

Therefore, the minimum value of the function is 9 at x=9, which is the vertex of the parabola.

The function y=(x−9)²+9 is an upward parabola, and hence it never stops increasing, which means that the function has no maximum value.

Thus, the minimum value of the function is 9, and the function never stops increasing.
