Louis is constructing the perpendicular bisector
of GH . He has already constructed an arc as
shown.
What should Louis do for his next step?
Answers
Solution :
It is given that Louis is constructing a perpendicular bisector of a line GH.
Let the line GH be x units of length.
Louis is constructing a perpendicular bisector. So he should follow the following steps :
1. Louis should take the help of a compass and place the needle of the compass on one end of the line and take a measurement that is equal to the more than half the length of the line GH.
2. Then keeping the compass needle at one end of he line, Louis have to draw an arc above and below the line GH.
3. Now with the same measurement in the compass, place the compass needle on the other end and similarly cut two arcs above and below intersecting the previous arcs.
4. Now join the intersecting point with a straight line.
5. This is the perpendicular bisector of the given line GH.

Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.
The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.
Use a linear model to predict the amount of gasoline that is present on the Jet after it has been in flight for 18 hours without stopping to refuel. In two or more complete sentences, explain your answer.
Answers
The prediction of the amount of gasoline that is present on the Jet after it has been in flight for 18 hours without stopping to refuel is given as follows:
-52,750 gallons.
(as the estimate is negative, it means that the plane has to stop to refuel before that).
How to define the linear function?The linear function for this problem is defined in slope-intercept format, as follows:
y = mx + b.
The coefficients of the function are given as follows:
m is the slope, which is the gasoline spending per hour.b is the y-intercept, which is the initial amount of gasoline.The graph touches the y-axis at y = 422,000, hence the intercept b of the function is given as follows:
b = 422000.
When x = 2, y = 369250, hence the slope m is calculated as follows:
m = (369250 - 422000)/2 = -26375.
Then the linear function giving the amount of gasoline present after x hours is of:
y = -26375x + 422000.
After 18 hours, the estimate of the amount of gasoline in the tank is given as follows:
y = -26375(18) + 422000 = -52,750 gallons.

Mr.sampson is 12 years less than twice as old as Mr.rogers. the sum of their ages is 93. how old are they?
Answers
Answer:
Mr.Samson is 58 years old. Mr.Rogers is 35.
Step-by-step explanation
Samson's age Roger's age
2x - 12 x ( 12 years less than twice Mr.Rogers(x))
Equation: 2x - 12 + x = 93 Sum of ages is 93
3x - 12 = 93 Simplified
x = 35 Solve
Rogers = x, so Rogersis 35
But Sampson is 2x - 12 ( 2 * 35 - 12 ), so Sampson is 58

Answers
Answer:
Buddie
Buddie should enter on line 6 of the income section:
capital gains or losses that he incurred for the past year.
Step-by-step explanation:
Line 6 asks about the capital gains or losses from the past year so that the AGI total could be obtained before deductions are made. Where Line 6 is filled, there are some other forms that will accompany it, like Schedule D and 1099-B or 1099-S forms, which record the capital gains or losses. All capital gains that are not excludable must be stated for income tax purpose.

Derrick withdrew $17 from his account on Monday. The next day he
deposited $12 in his account. What integer represents the total change in
his account over these two days?
Answers
Answer:
The total change in his account is represented by the integer -5
Step-by-step explanation:
Operations With Integers
We need to perform addition and subtraction to complete the answer to this problem.
Derrick first withdrew $17 from his account. Since the money is coming out from the account, it's considered as negative. Thus this operation is recorded as -$17.
The next day he deposited $12, which is considered as positive. This operation is considered as $12 or +$12.
The net operation or total change in the account is: -$17 + $12.
Subtracting and simplifying: -$17 + $12 = -$5
The total change in his account is represented by the integer -5

[tex]5 - 2x = 3x[/tex] -> Equation

can pump in s seconds?
Answers
Answer:

Traveling on the express train from New York to Baltimore takes approximately 2 hours and 45 minutes. The local train travels the same route from New York to Baltimore and takes approximately 3 hours and 40 minutes. Rounding to the nearest tenth, how many times as long is the journey time of the local train as the journey time of the express train?
Answers
Answer:
The local train's journey time is 1.3 times as long as the journey time of the express train.
Step-by-step explanation:
Given that:
Travelling time of express train = 2 hours and 45 minutes
We will convert this time into minutes
Travelling time of express train = 2*60 + 45 = 120+45 = 165 minutes
Travelling time of local train = 3 hours and 40 minutes = 220 minutes
Let,
n be the number of times.
Local train travelling time = Number of times * Express train travelling time
220 = n * 165
Dividing both sides by 165
[tex]\frac{220}{165}=\frac{165n}{165}\\1.3 = n[/tex]
Hence,
The local train's journey time is 1.3 times as long as the journey time of the express train.

The ratio of nurses to docters a month ago was 3:5. Now, it's 4:5. You can tell that there aren't 4 nurses because 3 => 4 is only one nurse. If you duplicate both ratios (multiply both sides by 2), you get 6:10 (for a month ago) and 8:10 (now). This is correct because 6+2=8. Hope it helps!
The perimeter of a triangle is 6p2-4p+9 and two of its adjacent side are p2 -2p+1 and 3p2-5p+3.Find the 3rd side
Answers
Answer:
C = 2p² + 3p - 5
Step-by-step explanation:
Let A & B denote the other two adjacent sides respectively.
Let the third side be denoted by C
Given the following data;
Perimeter of triangle = 6p² - 4p + 9
Length of one side = p² - 2p + 1
Length of one side = 3p² - 5p + 3
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
P = A + B + C
6p² - 4p + 9 = p² - 2p + 1 + 3p² - 5p + 3 + C
6p² - 4p + 9 = 4p² - 7p + 4 + C
C = 2p² + 3p - 5
