A company pays each of its two office employees each Friday at the rate of $120 per day for a five-day week that begins on Monday. If the monthly accounting period ends on Tuesday and the employees worked on both Monday and Tuesday, the month-end adjusting entry to record the salaries earned but unpaid is:
Answer:
Debit Salaries Expense $480 and credit Salaries Payable $480
Step-by-step explanation:
Firstly, we will need to calculate the salary expense of the company on these two employees.
Mathematically, that would be
2 employees * 2 days * 120/employee/day = 2 * 2 * 120 = $480
Thus, the month-end adjusting entry to record the salaries earned but unpaid is that salaries expense will be debited $480 and salaries payable will be credited $480

Parallel lines e and f are cut by transversal b. Horizontal and parallel lines e and f are cut by transversal b. At the intersection of lines b and e, the uppercase right angle is (2 x + 18) degrees. At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees and the bottom right angle is y degrees. What is the value of y? 16 50 130 164
Answer:
Angle y measures 130 degrees
Step-by-step explanation:
Notice that the angles marked as "2x+18", and "4x-14" must be equal angles since they are generated on the same sector (top right) of the parallel lines by the transverse line "b".
Then by finding the value of "x" we can deduce the value of the actual angle these two angles measure:
[tex]2x+18=4x-14\\18+14=4x-2x\\32=2x\\x=16^o[/tex]
Now, we can find the actual value of these two angles, we use for example the first expression:
Top-right angle = [tex]2\,(16^o)+18^o=50^o[/tex]
Now, if these two angles measure [tex]50^o[/tex], then angle "y" (which is the supplementary angle (angle which added renders [tex]180^o[/tex] ) for them, must equal [tex]180^o-50^o=130^o[/tex]

Stunt Double A movie stunt double jumps from the top of a
building 50 feet above the ground onto a pad on the ground
below. The stunt double jumps with an initial vertical velocity
of 10 feet per second.
a. Write and graph a function that models the height h (in feet)
of the stunt double t seconds after she jumps.
b. How long does it take the stunt double to reach the ground?
Answer:
2.1 s
Step-by-step explanation:
1. Write the equation
The formula for vertical displacement is
y = h + v₀t - ½gt²
h = 50 ft
v₀ = 10 ft/s
g = 32.2 ft/s²
Insert the values
y = 50 + 10t - ½ × 32.2t²
y = 50 + 10t - 16.1t²
The graph below shows the height as a function of time.
2. Solve the equation
a = -16.1; b = 10; c = 50
[tex]\begin{array}{rcl}x & = & \dfrac{-b\pm\sqrt{b^2 - 4ac}}{2a}\\\\& = & \dfrac{-10\pm\sqrt{10^2-4(-16.1) \times 50}}{2(-16.1)}\\\\& = & \dfrac{-10\pm\sqrt{100 - (-3220)}}{-32.2}\\\\& = & \dfrac{-10\pm\sqrt{100 + 3220}}{-32.2}\\\\& = & \dfrac{-10\pm\sqrt{3300}}{-32.2}\\\\& = & \dfrac{-10\pm 57.62}{-32.2}\\\\\end{array}[/tex]
[tex]\begin{array}{rcl}x = \dfrac{-10 + 57.62}{-32.2}& \qquad & x = \dfrac{-10 -57.62}{-32.2}\\\\x = \dfrac{47.62}{-32.2}& \qquad & x = \dfrac{-67.62}{-32.2}\\\\x = -1.479& \qquad & x =\textbf{ 2.1 s}\\\\\end{array}\\\text{It takes the stunt double $\large \boxed{\textbf{2.1 s}}$ to reach the ground.}[/tex]
Aitanacompreparaaitana compra para su fiesta de cumpleaños 5 litros de refresco y vasos de plastico de una capacidad de 250 metros cubicos ¿cuantos vasos podria servir en total?
Answer:
None
Step-by-step explanation:
In this case we must pass everything to the same unit of measure, we know that the total is 5 liters of soft drink and that each plastic cup has a capacity of 250 cubic meters.
We know that 1 liter is equivalent to 0.001 cubic meters, therefore we will pass the cubic meters of the plastic cup to liters, like this:
250 m ^ 3 * 1 L / 0.001 m ^ 3 = 250,000 L
Therefore we realize that the glass has a very large capacity, which suggests that there is an error in the statement, maybe it is not a cubic meter but a cubic centimeter, but as it is, it cannot serve any plastic cup because the capacity of this cup is very large with respect to the total amount of soft drink.
Calculate the rate of change for the quadratic function over the given interval: f\left( x \right) = {x^2} + 4x + 5;\; - 1 \le x \le 2f(x)=x 2 +4x+5;−1≤x≤2 1 5 2 -4
Answer: The rate of change is 5.
Step-by-step explanation:
Our equation is:
f(x) = x^2 + 4x + 5
And we want to find the rate of change in the range −1≤ x ≤2
when we want to find the rate between x1 ≤ x ≤ x2
we have:
Rate = (f(x2) - f(x1))/(x2 - x1)
So we have:
Rate = ( f(2) - f(-1))/(2 - 1)
Rate = (2^2 + 4*2 + 5 - (-1)^2 - 4*(-1) - 5)/3 = 15/3 = 5
The rate of change is 5.

What is the measure of angle Y, in degrees?
Answer:
The answer would be 116
Step-by-step explanation:
The angles X and Z would be equal at 32 so multiply them by 2 and you would get 64 subtract 64 from 180 and you would get 116
Answer:
Y =116
Step-by-step explanation:
We know that angle Z = angle X since they are base angles and the sides are the same length
The sum of the angles of a triangle are 180
X+Y+Z = 180
32+ Y + 32 = 180
64+Y=180
Y = 180-64
Y =116

1. The perimeter of a square is 18.4 m. What is its area?
Answer:
A ≈ 21.16m²
Step-by-step explanation:
Answer:
21.16 m^2
Step-by-step explanation:
If the perimeter is 18.4 m, then the length of a side is 18.4 m / 4, or 4.6 m.
Then the area of the square is (4.6 m)^2, or 21.16 m^2
An airplane travels 150 miles horizontally during a decrease of 35,000 feet vertically.
1. What is the angle of descent?
2. How long is the plane's path?
*teacher hint* remember to convert feet to miles or miles to feet or your answer will not make sense
The airplane's path is an illustration of right-triangles
The angle of descent is 2.5 degreesThe plane's path is 150.15 milesThe angle of descentRepresent the angle of descent with [tex]\theta[/tex]
The angle of descent, [tex]\theta[/tex] is then calculated using the following tangent identity
[tex]\tan(\theta) = \frac{35000\ feet}{150 \ miles}[/tex]
Convert feet to miles
[tex]\tan(\theta) = \frac{6.6287879\ miles }{150 \ miles}[/tex]
Divide
[tex]\tan(\theta) = 0.0442[/tex]
Take the arc tan of both sides
[tex]\theta = \tan^{-1}(0.0442)[/tex]
Evaluate the arc tan
[tex]\theta = 2.5[/tex]
Hence, the angle of descent is 2.5 degrees
The plane's pathRepresent the plane's path with p
The plane's path is calculated using the following Pythagoras theorem
[tex]p^2 = (150\ miles)^2 + (35000\ feet)^2[/tex]
Convert feet to miles
[tex]p^2 = (150\ miles)^2 + (6.6287879\ miles)^2[/tex]
Evaluate
[tex]p^2 = 22543.940829[/tex]
Take the square roots
[tex]p = 150.15[/tex]
Hence, the plane's path is 150.15 miles
