Richard's net pay for the week, considering Social Security, Medicare, and FIT deductions, can be calculated by subtracting the total deductions from his gross earnings.

First, let's determine the amount deducted for Social Security. The Social Security rate is 6.2%, and the maximum earnings subject to this deduction are $118,500. Since Richard is $1,000 below the maximum level, the amount subject to Social Security deduction is $1,000. Therefore, the Social Security deduction is 6.2% of $1,000.

Next, we calculate the Medicare deduction. The Medicare rate is 1.45%, and it is applied to the entire earnings of $1,700.

To calculate the FIT deduction, we need additional information about Richard's taxable income, tax brackets, and exemptions. Without this information, we cannot provide an accurate calculation for the FIT deduction.

Finally, we subtract the total deductions (Social Security, Medicare, and FIT) from Richard's gross earnings of $1,700 to obtain his net pay for the week.

Answer:

-12 and 1

Step-by-step explanation:

If you multiply 12 by 1 you get 12, hence if you add -12 and 1 now you will get -11

The two numbers that multiply to be 12 and add to be -11, obtained using the quadratic formula are;

(-11 + √(73))/2, and 24/(-11 + √(73))

(-11 - √(73))/2 and 24/(-11 - √(73))

The quadratic formula is a formula that can be used to find the solution to a quadratic equation in the form; y = a·x² + b·x + c, where a ≠ 0, and a, b, and c are constant.

The quadratic formula can be presented as follows;

x = \(\frac{-b\pm \sqrt{b^2 - 4\cdot a \cdot c} }{2\cdot a}\)

Let x represent one of the numbers,. and let y represent the other number, we get;

x × y = 12...(1)

x + y = -11...(2)

Solving for y in the first equation, we get;

y = 12/x

Substituting the value for y above in equation (2), we get;

x + 12/x  = -11

x² + 12 = -11·x

x² + 11·x + 12 = 0

Solving the above equation using the quadratic formula, we get;

x = (-11 ± √(11² - 4×1×12))/(2 × 1)

x = (-11 ± √(73))/2

When x = (-11 + √(73))/2, y = 12/((-11 + √(73))/2) = 24/(-11 + √(73))

When x = (-11 - √(73))/2, y = 24/(-11 - √(73))

The two combination of numbers that multiply to be 12 and add to be -11 are;

(-11 + √(73))/2 and 24/(-11 + √(73)), and (-11 - √(73))/2 and 24/(-11 - √(73))

In perimeter, The cost to frame Joy's math certificate in a fancy frame is $138.00.

The dimensions of Joy's math certificate are 10 inches tall and 13 inches wide.

Joy wants to frame it in a fancy frame that costs $3.00 per inch.

To determine the total cost of framing the certificate, we need to find its perimeter and then multiply that by the cost per inch.

The perimeter of the certificate is:

Perimeter = 2 × (height + width)

Substituting the given values, we get:

Perimeter = 2 × (10 + 13)Perimeter = 46 inches

Therefore, the total cost of framing Joy's math certificate is:

Total cost = Perimeter × Cost per inch

Total cost = 46 × 3.00Total cost = $138.00

Thus, the cost to frame Joy's math certificate in a fancy frame is $138.00.

Answer:

91.204 cubic feet

Step-by-step explanation:

We are given that

Height of great pyramid, h=480feet

Side of square base, a=755  feet

Height of Danny's pyramid, h'=480/100 feet

Side of square base of Danny's pyramid, a'=755/100 feet

We have to find the volume of Danny's pyramid if the volume of Danny's pyramid is 1/100 the size of great pyramid.

We know that

Volume of square base pyramid, V=\(\frac{1}{3}a^2h\)

Where a= Side of base

h=Height of pyramid

Using the formula

Volume of Danny's pyramid=\(\frac{1}{3}\times(755/100)^2(480/100)ft^3\)

Volume of Danny's pyramid=91.204 cubic feet

The length x of a diagonal support, to the nearest tenth of a foot is; 11 ft

Let us say the side opposite to the 25° angle is a, in both triangles. The side opposite to the 65° angle is b, but we already know the length of b as it is 20/ 2 = 10 ft.

We should find the length of a using trigonometric ratios, and by Pythagorean Theorem, determine the length of x.

Thus;

a = tan 25 * ( 10 )

a ≈ 4.663 ft

b = 10 ft

By Pythagorean Theorem,

a² + b² = x²

4.663² + 10² = x²

21.74 + 100 = x²

x² = 121.74

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:

= x² + 3x² + 3x² - 6xy - 3xy + 4xy + 9y² - 4y² + 3x

= 7x² - 5xy + 5y² + 3x

The simplified form of the expression is 7x² - 5xy + 5y² + 3x.

The logistic model is a mathematical function that depicts how a limited quantity grows. To use a sketch of the phase line to argue that any solution to the logistic model approaches the equilibrium solution p(t) a b as t approaches infinity, the first step is to sketch the region where p(t) is increasing and decreasing.

The logistic model is a mathematical function that depicts how a limited quantity grows. This model is given by;\($$\frac{dp}{dt}=aP(1-\frac{P}{b})$$\) where a, b, and p0 are positive constants.To use a sketch of the phase line to argue that any solution to the logistic model approaches the equilibrium solution p(t) ≡ a b as t approaches infinity, let's follow the below steps.

Step 1: Sketch the phase lineThe logistic model's phase line can be illustrated by showing the regions where p(t) is increasing and decreasing. To depict the phase line, the equilibrium solution needs to be located at pb. For a solution to approach the equilibrium solution p(t) ≡ a b as t approaches [infinity], it implies that the solution must be to the right of pb on the phase line. As the curve approaches infinity, it gets closer to the equilibrium solution p(t) ≡ a b, as shown in the below sketch.

Step 2: Use the sketch to argue any solution approaches equilibriumThe phase line indicates that any solution on the left-hand side of pb on the phase line will approach zero as time increases. Thus, the equilibrium solution p(t) ≡ a b is the only stable solution when t approaches infinity. Therefore, any solution to the logistic model below, where a, b, and p0 are positive constants, approaches the equilibrium solution p(t) ≡ a b as t approaches [infinity].

The perimeter of the triangle if y equals 3 feet is 31 feet.

Given:

sides of the triangle are y+5, 4y-3 and 3y+5 feet.

y = 3 feet

Let a = y + 5 = 3+5 = 8.

so a = 8 feet.

b = 4y - 3

= 4*3 - 3

= 12 - 3

b = 9 feet.

c = 3y+5

= 3*3+5

= 9+5

c = 14 feet.

Perimeter of the triangle = a+b+c

= 8 + 9 + 14

= 17 + 14

= 31 feet.

The plane will reach an altitude of 21,000 feet approximately 29.2 minutes after lift off. Rounded to the nearest whole minute, the plane will be at an altitude of 21,000 feet 37 minutes after lift off.

To determine the number of minutes after lift off when the plane reaches an altitude of 21,000 feet, we need to solve the equation a = 21,000, where "a" represents the altitude in feet. By substituting the altitude value into the equation and solving for the variable, we can find the number of minutes.

The given equation represents the altitude "a" of the plane in feet, given by a = 3480 + 600t, where "t" represents the time in minutes after lift off. We need to find the number of minutes when the plane is at an altitude of 21,000 feet.

By substituting a = 21,000 into the equation, we have:

21,000 = 3480 + 600t

To isolate "t," we subtract 3480 from both sides:

21,000 - 3480 = 600t

Simplifying, we get:

17,520 = 600t

Dividing both sides by 600, we find:

t = 29.2

Here we will show you how to calculate the angle in degrees made by the hour hand and minute hand on a 12-hour clock at 11:12.

Before we continue, note that a clock is shaped like a circle and is composed of 360 degrees.

There are 60 minutes in an hour, and 360 degrees divided by 60 minutes is 6. Therefore, the minute hand moves 6 degrees per minute.

As you can see, the hour hand and minute hand showing 11:12 on the clock make an angle. We used the hands to make the pie chart below so it is easier to visualize what we are calculating.

The hour hand and minute hand on a clock showing 11:12 actually make two angles: The hour hand to the minute hand is outlined in blue, and the minute hand to the hour hand is outlined in red.
