What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
(a).By using formula we get;
Regular gross pay= Regular Hours x Hourly Rate
D2=B2*C2
(b) By using the formula we get;
Overtime Hours = Hours Worked -Regular Hours
E2=A2-B2
(c) By using the formula we get;
Time-and-a-half overtime
hourly rate = Hourly rate 1.5
F2=C2x1.5
(d) By using the formula we get;
Total overtime pay
=Overtime Hours x Overtime rate
G2=E2 x F2
(e) By using the formula we get;
Total weekly pay = Regular pay + Overtime pay
H2=D2+G2
Therefore, the unitary answer will be H2=D2+G2

Is 1 2 a half or half?
Answer: half
Step-by-step explanation:
A circle is centered at O. The tangent to the circle at P is extended to Q. Line segment QS intersects the circle at R. Given that OS = 2, SR = RQ = 3, and PQ = 6, find the radius of the circle.
The radius of the circle will be [tex]\sqrt{22}[/tex].
In our question, we shall first extend QRS to the circle's point T.
According to the power of a point.
[tex]QP^{2}[/tex] = QR*QT
[tex]6^{2}[/tex] = 3*QT
QT = 12
Since QR = 3, RT = 9.
Since RS = 3, ST = 6.
Draw OT and OR, creating a triangle(TSO) and triangle(RSO).
OT and OR are radii, Let the radius be r.
Use the Law of Cosines on these two triangles.
OT2 = [tex]r^{2}[/tex] = [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)
OR2 = r2 = [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)
Since these are equal:
[tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO) = [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)
40 - 24*cos(TSO) = 13 - 12*cos(RSO)
Since angle(RSO) is supplementary to angle(TSO), cos(RSO) = - cos(TSO)
40 - 24*cos(TSO) = 13 + 12*cos(TSO)
27 = 36*cos(TSO)
0.75 = cos(TSO)
Since [tex]OT^{2}[/tex] = [tex]r^{2}[/tex] = [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)
[tex]r^{2}[/tex] = 40 - 24*0.75
[tex]r^{2}[/tex] = 22
r = [tex]\sqrt{22}[/tex]
Hence the radius of the given circle will be [tex]\sqrt{22}[/tex].

Step-by-step explanation:
band-aids are packaged in 100 per box. you had four full boxes when you started work yesterday. at the end of the day, you had two full boxes left. what percentage of them were used yesterday?
Out of 400 band-aids, 200 were used yesterday. Therefore, the percentage of band-aids used yesterday is 50%.
You started with 4 boxes × 100 band-aids per box
= 400 band-aids.
You ended with 2 boxes × 100 band-aids per box
= 200 band-aids
So you used
400 band-aids - 200 band-aids = 200 band-aids yesterday.
To find the percentage of band-aids used, you can divide the number of band-aids used by the total number of band-aids you started with and multiply by 100:
= (200 band-aids / 400 band-aids) × 100

The position number for term 47 is 269.
This is an arithmetic sequence since each term has a common difference. Let us test it.
The difference between 1st and 2nd terms is
-7 + d = -1
d = -1 + 7
= 6
Now we check the difference for term
The difference between 3rd and 4th terms is
5 + d = 11
d = 11 – 5
= 6
So the difference is the same so we can apply a common equation for arithmetic sequence
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )
Where :

(3 points) part c: find the value of integral from 4 to 9 of 2 times g of x minus f of x end quantity dx. show the work that leads to your answer. (4 points)
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x.
Part a:
The value of the integral from 0 to 6 of f(x)dx is 16. This can be calculated using the Fundamental Theorem of Calculus (FTC) which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫f(x)dx = F(6) - F(0)
The anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫f(x)dx = (62 + 2*6) - (02 + 2*0) = 36 - 0 = 16.
Part b:
The value of the integral from 4 to 9 of g(x)dx is 20. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫g(x)dx = G(9) - G(4)
The anti-derivative of g(x) is G(x) = x3 + 3x2, so the value of the integral is:
∫g(x)dx = (93 + 3*9) - (43 + 3*4) = 729 - 168 = 20.
Part c:
The value of the integral from 4 to 9 of 2*g(x) - f(x)dx is 68. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫(2*g(x) - f(x))dx = 2*G(9) - F(9) - [2*G(4) - F(4)]
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫(2*g(x) - f(x))dx = (2*(93 + 3*9) - (92 + 2*9)) - [2*(43 + 3*4) - (42 + 2*4)]

find the point on the line y=2x+3 that is closest to the origin
From the given line equation, the closet point to the origin is (-6/5, 3/5).
Here we have given that the point on the line y=2x+3 that is closest to the origin.
As we all know that the closest point from origin will be the perpendicular distance from origin to the line.
Here we need to find an equation of the perpendicular from (0,0) on y = 2x + 3.
As we all know that the standard form of the equation is in slope-intercept form is written as,
=> y = mx + c
While we comparing this with the given equation, then we get the value of the Slope that is m = 2 and the Slope of the perpendicular is calculated as,
=> - (1/m) = -1/2
Now, we have to write the equation of the perpendicular is found by using the formula,
=> (y - y1) = m (x - x1)
Apply the value on the equation, then we get,
=> y - 0 = (-1/2) (x - 0)
=> y = (-1/2)x
therefore, the resulting perpendicular equation is written as,
=> 2y + x = 0 ----------------(2)
When we solving (1) and (2), then we get,
=> 5y = 3
Therefore, y = 3/5
And the value of x is calculated as
=> x + 2(3/5) = 0
=> x = -6/5
So the point on the line is (-6/5, 3/5).

Help me solve this triangle cuz im at 99
Answer:
Given: QR = QS (by given)
We are to prove: LS = ZR
Proof:
Since QR = QS, by the SAS (Side-Angle-Side) congruence postulate, we know that triangle QRS is congruent to triangle QSZ (both have two equal sides and included angle).
By the AAS (Angle-Angle-Side) congruence postulate, we know that if two angles of one triangle are congruent to two angles of another triangle, and the included side is congruent, then the two triangles are congruent.
Therefore, by using AAS congruence, we can say that triangle QRS is congruent to triangle QSZ.
By the CPCTC (Corresponding parts of congruent triangles are congruent), we know that if two triangles are congruent, then their corresponding sides are congruent.
Therefore, LS is congruent to ZR.
Therefore, we have proved LS = ZR
Note: The above proof uses the properties of congruence of triangles, if the student is not familiar with this, it might be challenging for them.
For every one litre of water used to make medicine,199ml of sucrose and 271ml of saline solution are used. express the amount of water,sucrose and saline solution needed as a ratio in its simplest form.
The ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.
The amount of water, sucrose, and the saline solution used can be expressed as a ratio in its simplest form by finding the greatest common divisor (GCD) of the three quantities and dividing each by it.
1l of water = 1000 ml of water.
Let's find the GCD of the three quantities:
GCD(199,271,1000) = 1
So we can express the amount of water, sucrose, and saline solution needed as a ratio in its simplest form by dividing each of the three quantities by 1
Water : Sucrose : Saline solution = 1000 : 199/1 : 271/1 = 1000:199:271
Hence, the ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.

Which inequality represents all the solutions of 10(3x + 2) > 7(2x − 4)?
Answer:
Step-by-step explanation:
The inequality that represents all the solutions of 10(3x + 2) > 7(2x − 4) is 10(3x + 2) > 7(2x − 4). To solve this inequality, first we must combine like terms on each side of the inequality. On the left side, 10(3x + 2) becomes 30x + 20. On the right side, 7(2x − 4) becomes 14x − 28. After combining the like terms, the inequality becomes 30x + 20 > 14x − 28. Next, we must subtract 14x from both sides of the inequality. On the left side, 30x + 20 becomes 16x + 20. On the right side, 14x − 28 becomes −28. After subtracting 14x from both sides, the inequality becomes 16x + 20 > −28. Finally, we must subtract 20 from both sides of the inequality. On the left side, 16x + 20 becomes 16x. On the right side, −28 becomes −48. After subtracting 20 from both sides, the inequality becomes 16x > −48. To solve the inequality, we must divide both sides of the inequality by 16. On the left side, 16x becomes x. On the right side, −48 becomes −3. Therefore, the solution to the inequality is x > −3.
