Step-by-step explanation:
8 + (22 + 15) = 8 + 37 = 45
To evaluate the expression, we must first perform the operations inside the parentheses. In this case, 22 + 15 = 37. Then we can add 8 to that result, which gives us 8 + 37 = 45. So the final value of the expression is 45.
Answer:
Using BODMAS, you are to solve the one in the bracket
22+15 which=37
then you add it to 8
37+8=45
Assuming all the workers employed at the beanbag factory are of equal ability,
what might the beanbag factory do to address the diminishing marginal returns it
experiences after the hire of its third worker?
A. Fire the manager.
B. Invest in more equipment.
C. Hire more workers.
D. Wait for its workers to improve.
Assuming all the workers employed at the beanbag factory are of equal ability, the beanbag factory invest in more equipment to address the diminishing marginal returns it experiences after the hire of its third worker. So the option B is correct.
It is assumed that all of the factory's employed employees have the same level of skill. Additionally, it must follow that if they are working to their maximum ability, they will be able to accomplish the same amount of work as before.
Since the third man was hired, the quantity of work the three of them have completed has decreased, making it clear that he is to blame for the diminishing returns.
Therefore, it seems sense to fire the individual since he is either not performing to his full capacity or encouraging other employees to do the same.

a) The average of daily income of a plumber from Sunday to Friday is Rs 1,300 in the last week. If he earned Rs 2,000 on Saturday, find his average of daily income of the week.
Answer: To find the average of daily income of the week, we need to find the total income of the week and divide it by the number of days in the week.
We know that the average daily income of the week is Rs 1,300 and we know that he earned Rs 2,000 on Saturday. To find the total income for the week, we can add the Saturday income to the average daily income for the 6 days.
Therefore, the total income for the week = Rs 1,300 (average daily income) x 6 (days) + Rs 2,000 (Saturday income) = Rs 7,800 + Rs 2,000 = Rs 9,800
To find the average daily income for the week, we divide the total income by the number of days in the week (7)
Average daily income = Rs 9,800 / 7 = Rs 1,400
Therefore, the average daily income of the plumber for the week is Rs 1,400.

A circle has a circumference of 36 cm. What is the length
of an arc that has a measure of 190°?
The length of an arc that has a measure of 190° is equal to 9 cm.
How to calculate the length of an arc?In Mathematics, if you want to calculate the length of an arc formed by a circle, you will divide the central angle that is subtended by the arc by 360 degrees and then multiply this fraction by the circumference of the circle.
Mathematically, the length of an arc formed by a circle is given by:
Length of an arc = 2πr × θ/360
Length of an arc = C × θ/360
Where:
r represents the radius of a circle.C represents the circumference of a circle.θ represents the angle subtended by the arc.Substituting the given points into the length of an arc formula, we have the following;
Length of an arc = 36 × 90/360
Length of an arc = 36 × 1/4

The person will have to place the compasses 6 feet away from the point they want the arch to start, and draw the arch with a radius of 9 feet.
The radius of the arch is 9 feet.
The formula for calculating the radius of an arch is [tex]R = (width / 2) / sin(90°)[/tex].
Therefore, the radius of the arch is:

Answer: 5R
Step-by-step explanation:
Half a dozen =6 pieces
R30/6=5R
How much is one dozen?
One dozen is equal to 12, so one half of a dozen is 6.
If 6 candles are priced at R30, we can divide R30 by 6 to get the cost of 1 candle.
30 ÷ 6 = 5.
Therefore, each candle costs R5.

7. Segment MN has endpoints at M(-12,-5) and N(8, 10). A third point Q is located on MN such that MQ:ON=2:3. Answer the following questions. (a) Find the coordinates of Q. Show how you arrived at your answer.
Answer:
To find the coordinates of Q, we can use the concept of proportional division of line segments.
Given that MQ:ON = 2:3, it means that the ratio of the length of MQ to ON is 2:3.
Let's first find the vector that represents the direction of MN, which is the vector pointing from M to N. We can find this by subtracting the coordinates of M from the coordinates of N:
(8,10) - (-12,-5) = (20, 15)
This is the vector <20,15>
Now, we can find the point Q, which is located two thirds of the way from M to N, by multiplying the vector <20,15> by 2/5 and adding the result to the coordinates of M:
Q = M + (2/5) * <20,15>
= (-12,-5) + (2/5) * <20,15>
= (-12,-5) + <8,6>
= (8,1)
So, the coordinates of Q are (8,1)

Find the image of (-1,3) obtained by translating 2 units down, followed by a rotation of 270 counterclockwise about the origin.
The image of the point (-1, 3) is (1, 1).
What is Translation?A translation is a transformation that moves every point in a figure the same distance in the same direction.
For example, this transformation moves the parallelogram to the right 5 units and up 3 units. It is written ( x , y ) → ( x + 5 , y + 3 ) .
Given:
Pint( -1, 3).
Translating unit = 2 units down
According to the 270°-counterclockwise rotation [90°-clockwise rotation] rule, you take the y-coordinate, move it to your new x-coordinate, and then take the opposite of the x-coordinate and set it as your new y-coordinate:
Extended Rotation Rules
270°-clockwise rotation [90°-counterclockwise rotation] = (x, y) → (-y, x)
270°-counterclockwise rotation [90°-clockwise rotation] =(x, y) → (y, -x)
and, 180°-rotation = (x, y) → (-x, -y)
Thus, the 270°-counterclockwise rotation [90°-clockwise rotation] will be
[-1, 1] moves to [1, 1].
Hence, the translation is (1, 1).

If 8; 2x; 2y forms an arithmetic sequence and 2x ; 2y; 36 forms a geometric sequence determine the values of x and y. Arithmetic and Geometric Series
Answer:
36
Step-by-step explanation:
An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. A geometric sequence is a sequence of numbers in which any two consecutive terms have a constant ratio.
Given that 8, 2x, 2y is an arithmetic sequence, we know that:
2x - 8 = 2y - 2x
x = y
Given that 2x, 2y, 36 is a geometric sequence, we know that:
(2y)/(2x) = 36/2y
y^2 = 36x
Now, we can use the first equation to substitute for y in the second equation, and get:
x^2 = 36x
x^2 - 36x = 0
x(x-36) = 0
So x = 0 or x = 36
However, x cannot be equal to zero because in that case the second term of the arithmetic sequence will be zero, and it will not be a valid solution. Therefore, x = 36.
So, y = x = 36.
Therefore, the values of x and y are 36.
Find an equation of the plane passing through (0, -3,1) that is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7.
The equation of the plane passing through (0, -3,1) that is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16x - 8y + 8z = 32
We know that the equation of plane passing through point (x₁, y₁, z₁) is given by,
A(x - x₁) + B(y - y₁) + C(z - z₁) = 0
where, A, B, and C are direction ratios
In the question, the plane passes through point (0, -3,1)
Let (x₁, y₁, z₁) = (0, -3,1)
Using above formula the equation of the plane will be in the form,
A(x -0) + B(y - (-3))+C(z - 1) = 0
Ax + B(y + 3)+C(z - 1) = 0 ..........(1)
The required plane is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7.
So, their normal to the required plane would be perpendicular to the normal of both the planes.
The normal to the required plane is a cross-product of the normals of planes.
A cross-product of the normals of planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16i - 8j + 8k
So, the direction ratios,
A = 16, B = -8, C = 8
So equation (1) becomes,
16x - 8(y + 3) + 8(z - 1) = 0
16x - 8y - 24 + 8z - 8 = 0
16x - 8y + 8z - 32 = 0 is the required equation of the plane
