You manage a staff of 9 employees. Each employee has equally done an excellent job this year. If upper management has allotted a bonus for your department of $30,000, what dollar bonus amount would each employee get if divided equally (round to nearest dollar)?.
The amount that each employee will get out of the bonus to your department will be $3,000.
What will each employee get?
You manage a staff of 9 employees in your department which means that there are 10 people in total.
The amount that each person will get from the bonus will therefore be:
= 30,000 / 10 employees
= $3,000

in a wildlife park, there were 20 gray wolves. after a few years, there were 38 gray wolves what is the percent gain
The percent gain in the number of wolves is 90%.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
From the information, in a wildlife park, there were 20 gray wolves. after a few years, there were 38 gray wolves.
The percent gain will be:
= Increase in wolves / Previous number × 100
= (38 - 20) / 20 × 100
= 18/20 × 100
= 90%
Therefore, it should be noted that based on the information illustrated above, the percentage gain will be 90%.

2x - 5y = 14
y = 3x+5
Answer:
x = -3
y = -4
Step-by-step explanation:
2x - 5y = 14 ⇒ ( 1 )
y = 3x + 5 ⇒ ( 2 )
First, let us find the value of x.
For that let us use equation ( 1 ) and replace y with (3x + 5 ).
2x - 5y = 14
2x - 5 ( 3x + 5 ) = 14
Solve the brackets.
2x - 15x - 25 = 14
Combine like terms.
-13x - 25 = 14
Add 25 to both sides.
-13x = 14 + 25
- 13x = 39
Divide both sides by -13.
x = -3
Let us find the value of y.
For that, use equation (2) and replace x with (-3).
y = 3x + 5
y = 3 × -3 + 5
y = - 9 + 5
y = -4
The table below shows the linear relationship between
the distance in feet below sea level and the time in
seconds traveled by a submarine.
What is the rate of change low of the distance in the feet below sea level with respect to time that the box submarine traveled?
The rate of change of the distance with respect to time that the box submarine traveled is 11 feet per second
How to determine the rate of change of the distance with respect to time the box submarine traveled?A rate of change describes how one quantity changes in relation to another quantity.
Mathematically, it is defined as the change in one quantity divided by the change in the other quantity.
In this case, we have:
rate of change = change in distance / change in time
Use the data in the table:
rate of change = 545-380/15-0
rate of change = 165/15 = 11
Note: You can pick any 2 data points for the calculation
Therefore, 11 feeet per second is the rate of change of the distance in feet below sea level with respect to time that the box submarine traveled

x=4-y---------(2)
since x = 4 – y just substitute for eqn 1

At a distance of 6 meters, a person with average vision is able to clearly read letters 1.0 cm high.Approximately how large do the letters appear on the retina? (Assume that the retina is 1.7 cm from the lens.)
The size of the letters appear on the retina is 0.00289 cm
Given data:
To determine the size of the letters on the retina, use the concept of angular size and the relationship between object size, distance, and angular size.
Angular size is the measure of the angle subtended by an object as seen from a particular point, in this case, the eye.
Angular size = Object size / Distance
Object size = 1.0 cm
Distance = 6 meters
Angular size = 1.0 cm / 6 meters
To convert the distance to centimeters, multiply by 100:
Angular size = 1.0 cm / (6 meters * 100 cm/meter)
Angular size = 1.0 cm / 600 cm
Angular size = 0.0017 radians
The angular size of the letters is 0.0017 radians.
Now, to determine the size of the letters on the retina, calculate the linear size on the retina using the angular size and the distance from the lens to the retina.
Linear size on retina = Angular size * Distance from lens to retina
Angular size = 0.0017 radians
Distance from lens to retina = 1.7 cm
Linear size on retina = 0.0017 radians * 1.7 cm
Linear size on retina ≈ 0.00289 cm
Hence, the letters appear to be approximately 0.00289 cm in size on the retina.

1/10 of the m&m in the bag are red and 1/5 are blue. What fraction of alll the m&m are red and blue
Step-by-step explanation:
we need to bring them to the same denominator. in this case : 10
so, 1/10 of everything are red.
1/5 = 2/2 × 1/5 = 2/10 of everything are blue.
so, we now just add these two :
1/10 + 2/10 = 3/10
so, 3/10 are red and blue (rather red or blue, because none are red and blue)..
Find the midpoint of the segment with the following endpoints
(5,5) and (1,1)
The midpoint of the segment given (5,5) and (1,1) is (3, 3).
What is midpoint?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Coordinates of the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂)= [(x₁ + x₂)/2 , (y₁ + y₂)/2].
The midpoint of the line segment with endpoints (5,5) and (1,1)
= [ ( 5 + (1))/2 , ((5) + 1)/2 ]

∠Y = 56° = ∠Z
9) ∠J = 44° = ∠K
∠L = 136° = ∠M
How to find the angles of a quadrilateral?The sum of angles of a quadrilateral is equal to 180 degrees. Now, in the quadrilateral given, the two angles on the slant side always equal 180 degrees. Thus;
8) From the given trapezium, we can use the definition above to say that;
∠X + ∠Y = 180°
Thus;
(13x - 7)° + (8x - 2)° = 180°
21x - 9 = 180
21x = 189
x = 189/21
x = 9
Thus;
∠X = (13(9) - 7)°
∠X = 124° = ∠W
∠Y = 180° - 124°
∠Y = 56° = ∠Z
9) From the above, we can apply the same to this quadrilateral to get;
7x + 2 + 25x - 14 = 180
32x - 12 = 180
32x = 180 + 12
32x = 192
x = 192/32
x = 6
∠J = (7(6) + 2)

A concrete drain is 10m long, with an outside diameter of 1m and an inside diameter of 0.8m. Determine the volume of the concrete required to make the drain, to the nearest tenth of a cubic metre
Answer: To calculate the volume of the concrete required to make the drain, we need to find the volume of the cylinder formed by the outside diameter of the drain and subtract the volume of the cylinder formed by the inside diameter of the drain.
The formula for the volume of a cylinder is:
V = πr^2h
where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.
The radius of the base of the outside cylinder is 0.5m (the diameter of 1m divided by 2) and the height is 10m. The radius of the base of the inside cylinder is 0.4m (the diameter of 0.8m divided by 2) and the height is also 10m.
So the volume of the outside cylinder is:
V = π * 0.5^2 * 10 = 15.7 m^3
and the volume of the inside cylinder is:
V = π * 0.4^2 * 10 = 12.6 m^3
To find the volume of the concrete required to make the drain, we subtract the volume of the inside cylinder from the volume of the outside cylinder:
15.7 m^3 - 12.6 m^3 = 3.1 m^3
So the volume of concrete required to make the drain is approximately 3.1 cubic metres. To the nearest tenth of a cubic metre, this is 3.1 m^3.
