The following is a special trapezoid. Given WX is parallel to ZY. Which of the following is also true about trapezoid WXYZ?
∠W ≅ ∠Z
∠Z and ∠W are supplementary
∠W ≅ ∠X
∠X and ∠Y are complementary
Answer:
∠Z and ∠W are supplementary
Step-by-step explanation:
In the diagram given showing a special trapezoid, WX and ZY are two opposite sides that are parallel to each other.
Thus, consecutive angles would be supplementary.
Therefore, the only correct option that is true is:
∠Z and ∠W are supplementary.
The test options are incorrect as consecutive angles are not complementary and they are not in themselves congruent to each other.
They ARE supplementary so it WOULD be B <z and <w are supplementary

Step-by-step explanation:
A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink. A player applies a horizontal force of 0.5 N to the puck. Find the speed and the traveled distance 5 s later.
Answer:
1) The speed after 5 seconds is 13.[tex]\bar 8[/tex] m/s
2) The distance traveled after 5 seconds is 34.7[tex]\bar 2[/tex] meters
Step-by-step explanation:
1) The given parameters are;
The mass of the hockey puck, m = 0.18 kg
The horizontal force applied by the player, m = 0.5 N
The time at which the speed is calculated, t = 5 seconds after the force is applied
Therefore;
From the equation for the applied force, F = m × a. where a represents the acceleration, by substituting the known values get;
0.5 = 0.18 × a
∴ a = 0.5/0.18 = 50/18 = 25/9 = 2.[tex]\bar 7[/tex]
a = 2.[tex]\bar 7[/tex] m/s²
The speed after 5 seconds is given from the kinematic equation, v = u + a·t
Where;
v = The final velocity
u = The initial velocity = 0 m/s
t = The time = 5 seconds
By substitution of the known values, we get;
v = 0 + 2.[tex]\bar 7[/tex] × 5 = 13.[tex]\bar 8[/tex]
The speed after 5 seconds = 13.[tex]\bar 8[/tex] m/s
2) The distance traveled, s, after 5 seconds is given by the equation, s = u·t + 1/2·a·t²
From which we have;
s = 0 × 5 + 1/2 × 2.[tex]\bar 7[/tex] × 5² = 34.7[tex]\bar 2[/tex]
The distance traveled after 5 seconds = 34.7[tex]\bar 2[/tex] meters

$9,526 and $38,700, and 22 percent on Incomes between $38,701 and $82,500. In 2018, you made $42,000. What was your income tax this year?
O $5,040
$8,400
$4,200
$9,240
Answer:
$9,240.
Step-by-step explanation:
Given that in 2018, all salaries between $ 38,701 and $ 82,500 had to pay a federal income tax of 22%, and that my salary in that year was $ 42,000, to determine the amount that I had to pay in concept of said tax, the following calculation must be done:
(42,000 x 22) / 100 = X
924,000 / 100 = X
9,240 = X
Therefore, the amount of federal income tax that I had to pay in 2018 was $ 9,240.

If the cost of a competing factor of production, such as a machine that also could do the job, rises. This would result in a shift in the demand for this factor out to the right and would put pressure on the wage to rise. I don't understand why this is the case because I thought if machines replaced human labor then wouldn't wages be lower because there wouldn't be a need for human labor?
Keep in mind that we're framing it based on what the first sentence says, which is "If the cost of a competing factor of production, such as a machine that also could do the job, rises".
So if the cost of getting a machine part, various parts, or the entire machine cost rises, then demand for the machine will go down. This will make employers seek out substitutes. In this case, those substitutes would be human labor. As employers demand for labor goes up, the wages will rise assuming the supply of workers is held constant. If the supply of workers increased, then you could argue the wages could go down. So that's why I'm assuming the supply is held in check.

Paulo identifies one point on a line as (6,3), and he knows that the slope is 2. How can he derive the equation of the line
Answer:
y = 2x + 3
Step-by-step explanation:
Points (6,3) are x,y coordinates.
Use slope intercept form: y = mx + b
b = y intercept
m = slope
The equation that has a slope of 2 and passes through (6, 3) will be y = 2x - 9.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the equation is 2. Then the equation is given as,
y = 2x + c
The line is passing through (6, 3), then we have
3 = 2(6) + c
3 = 12 + c
c = 3 - 12
c = - 9
The equation will be given as,
y = 2x - 9
The equation that has a slope of 2 and passes through (6, 3) will be y = 2x - 9.

In a two-digit number, the first digit is 5 less than the second digit. The number itself is three times the sum of its digits. What is the number? (I WILL MARK BRAINLIEST)
Answer:
27
Step-by-step explanation:
taking the second digit as 'x'
as per question the first digit is 'x-5'
therefore putting this in the one, tens, hundreds form
u multiply the first digit by 10 and the second by 1
therefore,
10(x-5) + 1(x)
now you have that the 2-digit number is equal to twice the sum of the digits,
so
10(x-5) + 1(x) = 3 [ (x-5) + (x) ]
on solving
10x - 50 + x = 3 (2x - 5)
11x -50 = 6x - 15
taking 6x on the right and -50 on the left
11x - 6x = 50 - 15
5x = 35
therefore x = 7
now substituting this value we get that the number is

The product of two consecutive even integers is 8. Find the integers.
Note: each set of brackets represents one solution.
Answer:
-4 and -2
2 and 4.
Step-by-step explanation:
Let n be the first even integer.
Then the consecutive even integer will be represented by (n+2).
We know that their product is 8. So:
[tex]n(n+2)=8[/tex]
Solve for n. Distribute:
[tex]n^2+2n=8[/tex]
Subtract 8 from both sides:
[tex]n^2+2n-8=0[/tex]
Factor:
[tex](n+4)(n-2)=0[/tex]
Zero Product Property
[tex]n+4=0\text{ or } n-2=0[/tex]
Solve for n for each case:
[tex]n=-4\text{ or } n=2[/tex]
Hence, we will have two correct solutions.
Case 1: -4 and -2. -4(-2) is indeed 8.
Case 2: 2 and 4. 2(4) is also 8.
Hence, our solutions are:
-4 and -2
2 and 4.
How do the expressions 72 divided and -72divided by (-9) and compare when they are evaluated?
Complete question is;
How do the expressions 72 divided by 9 and -72 divided by (-9) compare when they are evaluated?
A. They have different values and are different signs.
B. They have different values but are the same sign.
C. They have the same value but are different signs.
D. They have the same value and the same sign
Answer:
D. They have the same value and the same sign
Step-by-step explanation:
For 72 divided by 9,it is;
72/9 = 8
Usually when we don't have any sign in front of a number, it is said to be positive.
Thus, the answer can be expressed as; +8
Also, when -72 is divided by (-9), it is;
-72/-9
The negative signs will cancel out to give; 8
Similar to the first division, since no sign is attached to 8,it is said to be positive as +8.
This means both divisions yield same values and same signs

Draco invests $5000. Approximately how long will it take for the investment to double if the rate is 10% compounded annually?
Answer:
I'm in 6th grade and I think it is 500
For the investment to double if the rate is 10% compounded annually,
it will take about 7 years and 3 months.
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n[tex])^{nt}[/tex]
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for.
Given:
Draco invests $5000.
Draco wants his investment to double.
That means, accrued amount = $10000
Interest rate = 10%
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 per year,
Then, by using the formula,
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )
t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )
t = 7.273 years
t = about 7 years 3 months
Therefore, the required time is about 7 years 3 months.

Susie is paying $538.66 every month for her $150,000 mortgage. If this is a 30 year mortgage, how much interest will she pay over the 30 years of payments?
Answer:
Step-by-step explanation:
So First we know she pays (538.66) every month (12months in a year ) for (30) years
So 538.66*12*30 = 193,917.60
Then, we take his total payment minus the what he originally owed.
193,917.60 - 150,000 = $43,917.60
Susie's monthly mortgage payment on her $150,000 home is $538.66. If the loan has a 30-year term, the total interest she will have to pay throughout that time will be $43,917.60.
What is a mortgage?
A mortgage is, to put it simply, a contract that a person forms after borrowing money from a lender (in this case, a bank) and giving the lender a guarantee (in the form of a real estate property) that the money will be paid back in full.
So first one must know as she pays 538.66 every month as there are 12 months in a year and for 30 years, the payment calculation is:
538.66 × 12 × 30 = 193,917.60
Then, deduct the amount he originally owed from his total payment.
193,917.60 - 150,000 = $43,917.60
Therefore, the total interest she will have to pay throughout that time will be $43,917.60.
