What is the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5

Answer:

To calculate the total cost of John and his family's meal (including tip and tax), we can follow these steps:

Calculate the tip amount by multiplying the bill amount by 20% (or 0.2): 65.00 x 0.2 = 13.00

Add the tip amount to the bill amount to get the subtotal: 65.00 + 13.00 = 78.00

Calculate the tax amount by multiplying the subtotal by 7% (or 0.07): 78.00 x 0.07 = 5.46

Add the tax amount to the subtotal to get the total cost: 78.00 + 5.46 = $83.46

Therefore, the total cost of John and his family's meal (including tip and tax) was $83.46.

To calculate the price of the suede jacket with a 20% discount and 8% tax, we can follow these steps:

Calculate the amount of the discount by multiplying the original price by 20% (or 0.2): 250 x 0.2 = 50

Subtract the discount amount from the original price to get the sale price: 250 - 50 = $200

Calculate the tax amount by multiplying the sale price by 8% (or 0.08): 200 x 0.08 = 16

Add the tax amount to the sale price to get the total price: 200 + 16 = $216

Therefore, the total price of the suede jacket with a 20% discount and 8% tax is $216.

To calculate the sale price of the bracelet with a 25% discount and 7% tax, we can follow these steps:

Calculate the amount of the discount by multiplying the regular price by 25% (or 0.25): 44 x 0.25 = 11

Subtract the discount amount from the regular price to get the sale price: 44 - 11 = $33

Calculate the tax amount by multiplying the sale price by 7% (or 0.07): 33 x 0.07 = 2.31

Add the tax amount to the sale price to get the total price: 33 + 2.31 = $35.31

Therefore, the sale price of the bracelet with a 25% discount and 7% tax is $35.31.

Step-by-step explanation:

The tin's actual diameter is 250 mm.

What do you mean by diameter?

A circular object, like a circle or sphere, has a diameter, which is the length of a straight line that runs through its centre. It is the separation between two locations on an object's edge that are the furthest apart and traverse the object's centre.

Here, if the tin's diameter in the illustration is 10 cm, the actual tin's diameter can be determined as follows:

Real Diameter is 2.5 times the image diameter.

2.5 x 10 cm is the actual diameter.

Real diameter is 25 cm.

To translate the actual dimension to millimetres (mm), we can multiply by 10:

Actual Diameter multiplied by 10 to convert to mm

Real Diameter = 25 cm x 10 in mm.

Actual Diameter is 250 millimetres.

As a result, the tin's actual diameter is 250 mm.

Step-by-step explanation:

Therefore, the measure of angle ABC is 35 degrees.

In geometry, a circle is a two-dimensional shape that is defined as the set of all points in a plane that are equidistant from a fixed point called the center. The distance between the center and any point on the circle is called the radius of the circle. A circle has many properties, such as diameter (a line segment passing through the center and having endpoints on the circle), circumference (the distance around the circle), and sector (a region bounded by two radii and an arc of the circle). The circle is one of the most important and frequently studied shapes in geometry and has many applications in mathematics, science, and everyday life.

Here,

Since chord AB is congruent to chord CB, it follows that they subtend congruent angles at the center of the circle.

Therefore, angle AOC is congruent to angle COB.

The sum of the angles at the center of the circle is 360 degrees, so we can find the measure of angle AOC as:

360° - 70° = 290°

Since angles AOC and COB are congruent, they must each measure half of 290°:

290° / 2 = 145°

Finally, angle ABC is an inscribed angle that subtends arc AC. Its measure is half of the measure of arc AC:

a. Tο evaluate 2cοs²(π/8) - 1, we can use the dοuble angle identity fοr cοsine:

cοs(2θ) = 2cοs²(θ) - 1

Where θ = π/8

cοs(2(π/8)) = 2cοs²(π/8) - 1

cοs(π/4) = 2cοs²(π/8) - 1

√2/2 = 2cοs²(π/8) - 1

2cοs²(π/8) = √2/2 + 1

2cοs²(π/8) - 1 = (√2/2 + 1) - 1 = √2/2

Therefοre, 2cοs²(π/8) - 1 = √2/2.

b. We can use the trigοnοmetric identity:

tο rewrite the denοminatοr οf the expressiοn as:

1 - tan²(11π/12) = 1/(1 + tan²(11π/12)) = 1/sec²(11π/12) = sec²(-π/12)

where we have used the fact that secant is an even functiοn, sο sec(-x) = sec(x).

Next, we can use the fοllοwing trigοnοmetric identities:

tan(-x) = -tan(x)

and

sec(-x) = sec(x)

tο rewrite the numeratοr οf the expressiοn as:

2tan(11π/12) = -2tan(-π/12) = -2(-tan(π/12))

Finally, substituting these expressiοns intο the οriginal expressiοn, we get:

2tan(11π/12)/(1 - tan²(11π/12)) = -2(-tan(π/12))/sec²(-π/12)

= 2tan(π/12)cοs²(π/12)

Answer: C

Step-by-step explanation:

Every x value can only have one specific y value. You will have to perform the vertical line test. Basically grab a ruler and  slide it across your graphs vertically ( drag the ruler upright from left to right). Look at your x intercepts and their specific y intercepts.

For A, it continously crosses over so it is not a function. For B, it is always crossing over 2 times so it is not a function. For C, every x intercept has a specific y value therefore it is a function. It crosses over at one point only. For D, the vertical is always crossing over 2 times therefore it will not be a function.

Answer:

C.

Step-by-step explanation:

If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

The vertical parabola is the only graph here that will only touch the graph at one point, so it is the only function.

The correct answer is D. They could file for bankruptcy and discharge some of their debt.

What is bankruptcy?

Bankruptcy is a legal process in which a person or business unable to pay outstanding debts to creditors can get a fresh start. It is a form of debt relief in which a debtor is relieved of some or all of their financial obligations and is protected from creditors.

In order to determine this answer, we first need to calculate the couple's monthly income. With an annual income of $86,000, their monthly income would be $7,166.67 ($86,000/12). If one of them loses their job, their monthly income would be reduced by $3,300, leaving them with a monthly income of $3,866.67.

Next, we need to compare this income to the state requirements based on the number of persons in the household. For a four-person household in Virginia, the monthly income requirement is $7,086.25 ($85,939/12). This means the couple's income is below the state requirement and they could file for bankruptcy and discharge some of their debt.

Angle M is 147 degrees.

A triangle is a geometric shape that consists of three line segments connected end-to-end to form a closed shape. These line segments are called sides, and the points where the sides meet are called vertices. The sum of the three interior angles of a triangle is always 180 degrees, and the length of each side must be less than the sum of the other two sides. Triangles can be classified based on the length of their sides and the size of their angles. For example, a triangle with all three sides of equal length is called an equilateral triangle, while a triangle with two sides of equal length is called an isosceles triangle. Triangles are used in many areas of mathematics, as well as in physics, engineering, and other sciences, to model and solve problems.

Since triangles XYZ and LMN are congruent, corresponding angles are congruent. Therefore, angle LMN = angle XYZ = 33 degrees.

To find angle NML, we use the fact that the sum of the angles in a triangle is 180 degrees. We have:

angle LNM + angle NML + angle MLN = 180 degrees

Substituting the given values, we get:

124 + angle NML + 33 = 180

Simplifying and solving for angle NML, we get:

angle NML = 180 - 124 - 33 = 23 degrees

Therefore, angle M is the exterior angle of triangle LMN at vertex N, which is equal to the sum of the remote interior angles. We have:

angle M = angle LNM + angle NML = 124 + 23 = 147 degrees

Therefore, angle M is 147 degrees

The graph of the cubic function y = ∛(x+1) -2 is attached below

A cube root function's graph is a curve that extends to both positive and negative infinity from its origin. An example of a power function is the cube root function, which is described by the equation y = ∛x, where the cube root sign (∛) stands for the inverse of raising a number to the power of three.

The cube root function yields a positive value of y when x is a positive integer. As an illustration, if x = 8, then y = √8 = 2. The cube root function, on the other hand, yields a negative value of y if x is a negative number. As an illustration, if x = -27, y = ∛(-27) = -3

To graph a cube root function, we can create a table of values by choosing several values of x and then calculating the corresponding values of y using the equation y = ∛x. Once we have several points, we can plot them on a coordinate plane and then connect them with a smooth curve to get the graph of the function.

Answer:

The orthocenter of triangle XYZ is (-6,4).

Step-by-step explanation:

To find the orthocenter of triangle XYZ, we need to first find the altitudes of the triangle.

The altitude of a triangle is a line that passes through a vertex of the triangle and is perpendicular to the opposite side.

Let's find the equation of the line passing through X(-9,5) and perpendicular to YZ. The slope of YZ is (8-3)/(-6+6) = 5/0, which is undefined. Therefore, YZ is a vertical line passing through the point (-6,3). The equation of this line is x=-6.

The line passing through X(-9,5) and perpendicular to YZ must be a horizontal line passing through X. Therefore, the equation of this line is y=5.

Similarly, the equation of the line passing through Y(-6,8) and perpendicular to XZ is x=-6.

The equation of the line passing through Z(-6,3) and perpendicular to XY is y=3.

Now, we need to find the intersection of these lines to find the vertices of the triangle's altitude.

The altitude from X passes through the point X(-9,5) and is perpendicular to the line YZ with equation x=-6. Therefore, the intersection of the altitude from X and YZ must have x-coordinate -6. Since the equation of the altitude from X is y=5, we get the point of intersection as (-6,5).

Similarly, the altitude from Y passes through the point Y(-6,8) and is perpendicular to the line XZ with equation x=-6. Therefore, the intersection of the altitude from Y and XZ must have x-coordinate -6. Since the equation of the altitude from Y is y=8, we get the point of intersection as (-6,8).

The altitude from Z passes through the point Z(-6,3) and is perpendicular to the line XY with equation y=3. Therefore, the intersection of the altitude from Z and XY must have y-coordinate 3. Since the equation of the altitude from Z is x=-6, we get the point of intersection as (-6,3).

Now that we have the vertices of the altitudes, we can find the equation of the lines passing through them.

The line passing through (-6,5) and (-6,8) is the line x=-6.

The line passing through (-6,5) and (-6,3) is the line y=4.

The line passing through (-6,8) and (-6,3) is the line x=-6.

Now, we find the intersection of the lines x=-6 and y=4. The intersection point is (-6,4).

Therefore, the orthocenter of triangle XYZ is (-6,4).

Option 2 is correct. The lines M and N can be said to be parallel. Yes, because angle 1 and angle 2 form a linear pair so (2) 180-129 = 51 and 2 and 7 are alternate interior angles with the same measure.

A linear pair is a pair of adjacent angles formed when two lines intersect. These angles are called a linear pair because they lie on the same line, and their non-common arms are opposite rays, which means they point in opposite directions. Since the sum of the measures of linear pairs is always equal to 180 degrees, these angles are also known as supplementary angles.
