Find the midpoint of NP⎯⎯⎯⎯⎯ given N(2a, 2b) and P(2a, 0).
Answer:
(2a, b )
Step-by-step explanation:
Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex](x₁ + x₂ ), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]
Here (x₁, y₁ ) = N(2a, 2b) and (x₂, y₂ ) = P(2a, 0), thus

n urn contains 3 red balls, 9 green, 2 yellow, 2 orange, and 4 purple balls. Two balls aredrawn, one at a time with replacement. Find the probability of drawing a green ball and an orangeball.
Answer:
[tex]\frac{9}{100}[/tex]
Step-by-step explanation:
Given:
Number of red balls, n(R) = 3
Number of green balls, n(G) = 9
Number of yellow balls, n(Y) = 2
Number of orange balls, n(O) = 2
Number of purple balls, n(P) = 4
Two balls are drawn one at a time with replacement.
To find:
Probability of drawing a green ball and an orange ball ?
Solution:
Total number of balls, n(Total) = 3 + 9 + 2 + 2 + 4 = 20
Formula for probability of an event E is given as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Probability that a green ball is drawn at first:
[tex]P(Green) = \dfrac{\text{Number of Green balls}}{\text {Total number of Balls}}[/tex]
[tex]P(Green) = \dfrac{9}{20}[/tex]
Now, the ball is replaced , so total number of balls remain the same i.e. 20.[tex]P(Orange) = \dfrac{\text{Number of Orange balls}}{\text {Total number of Balls}}[/tex]
[tex]P(Orange) = \dfrac{2}{20} = \dfrac{1}{10}[/tex]
[tex]P(Green\ then\ orange) = P(Green) \times P(Orange)\\\Rightarrow P(Green\ then\ orange) = \dfrac{9}{10} \times \dfrac{1}{10}\\\Rightarrow P(Green\ then\ orange) = \bold{ \dfrac{9}{100} }[/tex]

PLEASE HELP! I WILL GIVE BRAINLIEST (8.02 MC) A pair of equations is shown below: y = 7x − 9 y = 3x − 1 Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) Part B: What is the solution to the pair of equations? (4 points)
Answer:
Step-by-step explanation:
slope intercept form: y=mx+b
m= slope
b= y-intercept
y= 7x - 9
slope= 7
y-int.= -9
y= 3x - 1
slope 3
y-int.= -1
7x-9 = 3x-1
Add 9 to both sides: 7x = 3x +8
Subtract 3 from both sides: 4x = 8
Divide by 4 on both sides: x =2
Substitute 8 into the equation: y = 3(2) -1
y = 5

Astrid is in charge of building a new fleet of ships. Each ship requires 404040 tons of wood, and accommodates 300300300 sailors. She receives a delivery of 444 tons of wood each day. The deliveries can continue for 100100100 days at most, afterwards the weather is too bad to allow them. Overall, she wants to build enough ships to accommodate at least 210021002100 sailors.
To build the fleet of ships, Astrid must consider each of the given rates (i.e. the daily tons of wood, the sailors per ship, etc.). The available deliveries are enough to build ships that can accommodate at least 2100 sailors.
Given that:
Required quantities
[tex]Wood = 40\ tons[/tex]
[tex]Sailors = 300[/tex] per ship
Available quantities
[tex]Wood = 4\ tons[/tex] daily
[tex]Days = 100[/tex] at most
First, we calculate the total tons of woods Astrid can receive.
[tex]Total = Days \times Wood\ Available[/tex]
[tex]Total = 100 \times 4[/tex]
[tex]Total = 400\ tons[/tex] ---- in 100 days
Next, we calculate the number of ships that can be made from the 400 tons.
[tex]Ships = \frac{Total\ tons}{Wood\ Required}[/tex]
So, we have:
[tex]Ships = \frac{400}{40}[/tex]
[tex]Ships = 10[/tex]
This means that Astrid can build up to 10 ships
The number of sailors the ship can accommodate is:
[tex]Sailors = Ships \times Sailors\ per\ ship[/tex]
So, we have:
[tex]Sailors = 10 \times 300[/tex]
[tex]Sailors = 3000[/tex]
It means the 10 ships can accommodate 3000 sailors.
3000 sailors is greater than 2100 sailors.
So, we can conclude that she can build enough ship for the 2100 sailors.

Hey there! I'm happy to help!
First, let's find the length of GA. We can just subtract all of the other sides from the perimeter to find this.
172-56-56-35=25
We see that E'M' is 14 and EM is 35.
35/14=2.5
This means that all of the sides on the big pinball machine are 2.5 times bigger than those of the smaller one.
So, we take the length of GA and then divide it by 2.5 to see how big G'A' is.
25/2.5=10
Therefore, the length of G'A' is 10 inches.

The Acme Company lost 650 hours due to accidents on the job in the first quarter of the year. The average hourly wage of the employees who contributed to the lost hours was $15.00. The company benefits add 25% to the wages. Using the cost-of-lost-hours formula (employee hours lost X average loaded labour rate = cost), calculate the direct cost of the lost work hours. Discuss the approach you would use to estimate the hidden costs that would also be associated with the lost hours.
Your answer must be at least 200 words in length.
Answer:
Step-by-step explanation:
Given that ;
The Acme Company lost 650 hours due to accidents on the job in the first quarter of the year
The average hourly wage of the employees who contributed to the lost hours was $15.00 . i.e the direct labor cost = $15.00
The company benefits add 25% to the wages. = 0.25
The loaded labor cost = $15.00/hr × 0.25 = $3.75/hour
If we add the additional cost of benefit, then we have the loaded labor cost to be = $15.00/hour + $3.75/hour
= $18.75 / hour
However, the direct labor costs that the workers continued to receive without working. for the first quarter of the year by using the cost-of-lost-hours formula is :
= 650 hours × $15.00 / hours
= $9750
The hidden costs can be estimated from the Acme company's contributions to the employee. Given that the company benefits add 25% to the wage of the employee, therefore, this wage must be incorporated in order to find out the total wage cost for the lost work hours in the Acme company.
As a result of the company benefits, the fully loaded labor cost is 650 hours × $18.75 /hour which gives $12187.5.
Consequently, it is pertinent to determine the cost for additional benefits that the workers are receiving even though they are not working, this is achieved by the difference in the $9750 direct cost paid to labor and the benefits amount of $12187.5
i.e
the cost for additional benefits that the workers are receiving even though they are not working = $12187.5 - $9750 = $2437.5
Other ways the hidden cost can be estimated is by take note of the amount paid to the employee on the day the employee had an emergency, amount paid to the rescue team involved. etc

52 divided by 5424
198 div by 8549 but need to see how to get the correct answer . Don’t want to use a calculator
Answer:
52 / 5424 = 0.00958..
198 / 8549 = 0.0231 ..
Step-by-step explanation:
52 / 5424
First of all, you need to add 0 plus a coma → 0.
52 becomes 520, but this value is smaller than 5424, so we need to add another 0
5200 → another 0 → 52000
So now, we have 52000 / 5424.
We start, 5424 . 10 = 54240, we are higher than 52000, so let's try 9
5424 . 9 = 48816, great!
52000 - 48816 = 3184
This is smaller than 5424, so we need a zero, again. But we do not add 0 to the result, because we are in the decimal side
31840 → 31840 / 5424. We would try 6,
5424 . 6 = 32544. It's bigger!, We use 5
5424 . 5 = 27120!
31840 - 27120 = 4720. We get another 0
47200, and we try 8.
5424 . 8 = 43392
47200 - 43392 = 3808.
So we are going to add 0, until we have four digits that can be divided by 5424 and decimals are infinte.
52 / 5424 = 0.00958..
198 / 8549 → Need to add, the first 0 to convert 198 to 1980
1980 = 0. → Another zero
19800 = 0.0 → 19800 / 8549
We try 2 → 8549 . 2 = 17098
19800 - 17098 = 2702 → we add 0
27020 / 8549 → We try 3
8549 . 3 = 25647 → 27020 - 25647 = 1373 → we add 0
13730 / 8549 → We use 1 → 13730 - 8549 = 5181
As decimal are infinite, we can express the result as:
198 / 8549 = 0.0231 ..

2) With the compass pin at the beginning of the original line segment, open the compass width to the end of the original line segment
3) With the adjusted compass width from the above step place the compass pin at the plotted point of the new line segment and draw an arc in the region the new line segment is to be located
4) Select a point on the arc where the other end of the new line will be
5) From the selected point from the above step, draw a line to the point plotted as the beginning of the new line segment
6) The length of the line drawn above is the same as the length of the original line segment.
What is the value of x in the equation 3x-4y=65, when y=4?
x=13 1/4
x=21 2/3
x =23
x = 27
Hello there! :)
Answer:
[tex]\huge\boxed{x = 27}[/tex]
Given the equation:
3x - 4y = 65 where y = 4
Substitute in 4 for "y":
3x - 4(4) = 65
Simplify:
3x - 16 = 65
Add 16 to both sides:
3x - 16 + 16 = 65 + 16
3x = 81
Divide both sides by 3:
3x/3 = 81/3
x = 27.
The function f(x)=x^2 + ax + b has a minimum at (3,9) what are the values of a and b
Answer:
Step-by-step explanation:
The function is f(x)=x^2 + ax + b
Derivate the function:
● f'(x)= 2x + a
Solve the equation f'(x)=0 to find a
The minimum is at (3,9)
Replace x with 9
● 0 = 2×3 + a
● 0 = 6 + a
● a = -6
So the value of a is -6
Hence the equation is x^2 -6x+b
We have a khown point at (3,9)
● 9 = 3^2 -6×3 +b
● 9 = 9 -18 + b
● 9 = -9 +b
● b = 18
So the equation is x^2-6x+18
Verify by graphing the function.
The vetex is (3,9) and it is a minimum so the equation is right
A train travels 250 km with a average speed of 75 km/hr and 350 km with 70km/hr and 200 km with average speed of 30km/hr. What will the average speed of whole journey of the train?
Answer:
53 1/3 km/h
Step-by-step explanation:
average speed = (total distance)/(total time)
average speed = distance/time
time * average speed = distance
time = distance/(average speed)
250 km at 75 km/h
distance = 250 km
time = (250 km)/(75 km/h) = 3.33333... hours
350 km at 70 km/h
distance = 350 km
time = (350 km)/(70 km/h) = 5 hours
200 km at 30 km/h
distance = 200 km
time = (200 km)/(30 km/h) = 6.6666... hour
total distance = 250 km + 350 km + 200 km = 800 km
total time = 3.33333... hours + 5 hours + 6.66666... hours = 15 hours
average speed = (total distance)/(total time)
average speed = (800 km)/(15 hours)
average speed = 53 1/3 km/h
The average speed of whole journey of the train is 45 km/hr
Average speed is the ratio of total distance travelled to total time taken. It is given by:
Average speed = total distance / total time
Given that a train travels 250 km with a average speed of 75 km/hr, hence:
75 = 250/time
time = 3.33 hours
It the travel 200 km with average speed of 30km/hr, hence:
30 = 200/time
time = 6.67 hours
The total distance = 200 km + 250 km = 450 km
The total time = 3.33 hr + 6.67 hr = 10 hours
Average speed = total distance/total time = 450 km/10 hours = 45 km/hr
The average speed of whole journey of the train is 45 km/hr

In 2002, the population of a district was 22,800. With a continuous annual growth rate of approximately 5% what will the population be in 2012 according to the exponential growth function?
Answer:
37,139
Step-by-step explanation:
Given the following :
Population in 2002 = Initial population (P0) = 22,800
Growth rate (r) = 5% = 0.05
Growth in 2012 using the exponential growth function?
Time or period (t) = 2012 - 2002 = 10years
Exponential growth function:
P(t) = P0 * (1 + r) ^t
Where P(t) = population in t years
P(10) = 22800 * (1 + 0.05)^10
P(10) = 22800 * (1.05)^10
P(10) = 22800 * 1.62889
P(10) = 37138.797
P(10) = 37,139 ( to the nearest whole number)
