What is the approximate length of side a? A. 6.62 m B. 8.78 m C. 13.77 m D. 18.21 m​

Answer:

16Ft

Step-by-step explanation:

We can use proportions to solve this problem.

Let's let "x" be the height of the flagpole. We know that the sign is 4 feet high, and it casts a shadow of 1 1/4 feet. So we can set up the proportion:

4/1.25 = x/5

Simplifying the left side of the equation, we get:

4/1.25 = 16/5

Substituting into the original equation, we have:

16/5 = x/5

Multiplying both sides by 5, we get:

16 = x

Therefore, the height of the flagpole is 16 feet.

Answer:

Step-by-step explanation:

For her medical expenses, it has to be more than 7.5% of her gross income of $32,500 => 7.5% of $32,500 = $2437.5.

so her deduction for medical expenses is $19,500 - $2437.50 = $17,062.5

so her total itemized deduction is $6,320.00 + $17,062.50 = $23,382.50

Given Kristina will file a single so her standard deduction for 2022 is $12,950.

If she uses standard deduction, her taxable income is 32,500 - 19,500 = 13,000

For the first 10,000 taxed at 10% so it is 10,000 x 10% = $1,000

The next $3000 taxed at 12% = $360

Her total tax is $1,000 + $360 = $1,360

If she uses itemized deduction, her taxable income is 32,500 - 23,382.50 = 9117.5

For the first 10,000 taxed at 10% so it is 9117.5 x 10% = $911.75

The tax saved is $1,360 - $911.75 = $448.25

Hope this helps.

A system of equations are a pair of equations.

Given the system of equations

4/x - 2/y = 12 (1) and

5/x + 1/y = 8 (2)

We proceed to solve as follows.

Since we have

4/x - 2/y = 12 (1) and

5/x + 1/y = 8 (2)

Multiplying equation (1) by 1 and equation (2) by 2, we have that

4/x - 2/y = 12 (1) × 1 and

5/x + 1/y = 8 (2) × 2

4/x - 2/y = 12 (4)  and

10/x + 2/y = 16 (5)

Now, adding equations (4) and (5), we have that

4/x - 2/y = 12 (4)  

+

10/x + 2/y = 16 (5)

14/x = 28

14 = 28x

x = 14/28

x = 1/2

Substituting x = 1/2 into equation (1), we have that

4/x - 2/y = 12 (1)

4/(1/2) - 2/y = 12 (1)

4 × 2 - 2y = 12

8 - 2y = 12

-2y = 12 - 8

-2y = 4

y = 4/-2

Answer:

To calculate the periodic interest rate for an account billed monthly with an APR of 21.99%, we need to divide the APR by the number of billing periods in a year.

Since there are 12 months in a year for a monthly billing cycle, we can divide 21.99% by 12 to get the monthly periodic interest rate.

Periodic Interest Rate = APR / Number of Billing Periods in a Year

Periodic Interest Rate = 21.99% / 12

Periodic Interest Rate = 1.8325%

Rounding this answer to the nearest hundredth, we get a periodic interest rate of 1.83%.

Answer:

To determine how many loaves will not meet quality standards on Tuesday, we need to count the number of integers in the sample that are between 1 and 50, inclusive. From the given sample, we can see that there are 2 integers that fall between 1 and 50: 47 and 4. Therefore, we can predict that 2 loaves will not meet quality standards on Tuesday.

To calculate the difference between the number of sub-standard loaves produced on Monday and the number predicted to be sub-standard on Tuesday, we need to subtract the number of sub-standard loaves on Monday from the number predicted for Tuesday.

Number of sub-standard loaves on Monday = 50

Number predicted to be sub-standard on Tuesday = 2

Difference = 2 - 50 = -48

The difference is -48, which means that there were 48 fewer sub-standard loaves predicted on Tuesday than the number produced on Monday.

In the parallelogram ABCD the measure of ∠BEC is obtained as 113°.

What is a parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side.

It is given that ABCD is a parallelogram.

The measure of ∠EAD = 30°.

The measure of ∠EDA = 37°.

In the parallelogram ∠EBC = ∠EDA as they form alternate interior angles pair.

Similarly, ∠ECB = ∠EAD as they form alternate interior angles pair.

The measure of ∠ECB = 30°.

The measure of ∠EBC = 37°.

Since EBC forms a triangle, so the sum of the angles of a triangle is 180°.

The equation is -

∠ECB + ∠EBC + ∠BEC = 180°

Substitute the values into the equation -

30° + 37° + ∠BEC = 180°

67° + ∠BEC = 180°

∠BEC = 180° - 67°

∠BEC = 113°

Therefore, the measure of ∠BEC = 113°.

Answer:

I ammm really sorry for the question

The equation that shows  the damping ratio for a mass-spring-damper system which is defined in terms of the mass, m, stiffness, k, and damping, b is  ζ = b / (2sqrt(mk)).

The damping ratio ζ is defined as the ratio of the damping coefficient b to the critical damping coefficient b_c, which is the minimum damping required to prevent the system from oscillating.

The damping ratio is a dimensionless quantity that represents the amount of damping in the system relative to the critical damping needed to prevent oscillations. A higher damping ratio indicates a more heavily damped system, while a lower damping ratio indicates a less damped system that may oscillate more.

The motion of a mass-spring-damper system can be described by a second-order linear ordinary differential equation (ODE) of the form:

md²x/dt² + bdx/dt + kx = F(t)

where m is the mass of the system, b is the damping coefficient, k is the spring constant, x is the displacement of the mass from its equilibrium position, and  the external force applied to the system is F(t).

The critical equation will be -

b_c = 2√(mk)

Therefore, the damping ratio can be expressed as:

ζ = b / b_c

Substituting the expression for b_c into the above equation, we get:

ζ = b / (2√(mk))

Answer:

12 feet

Step-by-step explanation:

Let x be the length of the shorter part of the pipe.

According to the problem, the longer part is three times as long as the shorter part. Therefore, the length of the longer part is 3x.

We also know that the sum of the lengths of the two parts is equal to the original length of the pipe, which is 16 feet.

So we can write an equation:

x + 3x = 16

Simplifying this equation, we get:

4x = 16

Dividing both sides by 4, we get:

x = 4

So the length of the shorter part is 4 feet, and the length of the longer part is 3 times as long, or 3 × 4 = 12 feet.

To evaluate whether x or o won the tic tac toe game, we need to check for the three possible winning conditions:

The two solutions are (1, 1/7) and (3.36, 1)

Assume that you spend some time walking (t_w) and some time canoeing (t_c) to cover a 30-mile trip. We can use the following formula to relate the time spent walking and canoeing:

distance = speed × time

For the walking part of the trip, the distance covered is (30 - d), where d is the distance covered by canoeing. We know that the walking speed is 4 mph, so we can write:

(30 - d) = 4t_w

For the canoeing part of the trip, the distance covered is d. We know that the canoeing speed is 7 mph, so we can write:

d = 7t_c

We also know that the total time spent on the trip is:

t_w + t_c

So, the constraint equation is:

t_w + t_c = 30/4 + 30/7

Simplifying this equation, we get:

11t_w - 7t_c = 30

Now, to determine two solutions, we can arbitrarily assign a value to one of the variables and then solve for the other. Let's assume t_w = 1, then we get:

11(1) - 7t_c = 30

7t_c = 1

t_c = 1/7

So, one solution is t_w = 1 and t_c = 1/7.

Similarly, assuming t_c = 1, we get:

11t_w - 7(1) = 30

11t_w = 37

t_w = 3.36

So, another solution is t_w = 3.36 and t_c = 1.

To graph the equation, we can plot t_w on the x-axis and t_c on the y-axis, and then plot the line 11t_w - 7t_c = 30. The two solutions will be the points of intersection of the line with the axes.
