Answer: To create a linear model that represents the amount of fuel on the plane as a function of flight time, we need to use the given information to calculate the fuel burn rate of the airplane in gallons per hour.
Fuel burn rate = Fuel capacity ÷ Range
Fuel burn rate = 63,500 gallons ÷ 14,430 km = 4.4 gallons per km
We need to convert km to miles, as flight time is usually measured in hours and miles. We can use the conversion factor 1 km = 0.621371 miles to convert kilometers to miles.
Range in miles = Range in km ÷ 0.621371
Range in miles = 14,430 km ÷ 0.621371 = 23,594 miles
Fuel burn rate = Fuel capacity ÷ Range in miles
Fuel burn rate = 63,500 gallons ÷ 23,594 miles = 2.69 gallons per mile
Therefore, the linear model that represents the amount of fuel on the plane as a function of flight time, in hours, is:
Fuel on plane (in gallons) = Fuel capacity - Fuel burn rate x Flight time (in hours)
F(t) = 63,500 - 2.69t
where F(t) is the amount of fuel on the plane (in gallons) after flying for t hours.

Anna has leaned a ladder against the side of her house. the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high. what length is the best approximation for the distance along the ground from the bottom of the ladder to the wall? responses 2 m 2 m 3 m 3 m 4 m 4 m 5 m
The most accurate estimate of the distance on the ground between the wall and the bottom of the ladder is 2 meters.
One approach to tackle this problem is to apply trigonometry to establish the connection between the angle, height, and distance. Specifically, we can utilize the cosine function, which relates the adjacent side and the hypotenuse of a right triangle. In this case, the adjacent side represents the distance between the wall and the ladder, and the hypotenuse corresponds to the ladder's length. The given angle is 72 degrees.
By employing the formula cos(angle) = adjacent/hypotenuse, we can input the known values and determine the unknown distance:
cos(72) = distance/6
distance = 6 * cos(72)
distance is approximately 1.9 m
Thus, the most accurate estimation for the ground distance from the ladder's bottom to the wall is 2 m.

A pizza is divided into 16 equal pieces violet and sophie each ate 1/8 of the pizza on friday the next day sophie ate 1/2
of the pizza that was leftover how many of the pieces of the original pizza remain
Answer:
6 pieces of the original pizza remain.
Step-by-step explanation:
Initially, the pizza was divided into 16 equal pieces. Violet and Sophie each ate 1/8 of the pizza on Friday, so a total of 1/8 + 1/8 = 1/4 of the pizza was eaten on Friday.
This means that 3/4 of the pizza remained after Friday.
The next day, Sophie ate 1/2 of the remaining pizza. So she ate 1/2 * 3/4 = 3/8 of the original pizza.
Therefore, the amount of pizza that remains is 3/4 - 3/8 = 3/8 of the original pizza.
To convert this fraction to a number of pieces, we need to multiply it by the total number of pieces the pizza was divided into:
3/8 * 16 = 6 pieces

Glen spends a total of 9 hours writing a paper and finishing a project. He spends x hours on the paper and y hours finishing the project. Glen spends
1/1/2 more hours on the paper than he spends on the project. How many hours does Glen spend writing the paper?
Glen spends average 1 1/2 times more hours writing the paper than finishing the project, so he spends 9x/(x+y) hours writing the paper and 9y/(x+y) hours finishing the project.
Glen spends a total of 9 hours writing a paper and finishing a project. We can define x as the number of hours he spends writing the paper and y as the number of hours he spends finishing the project. Since Glen spends 1 1/2 times more hours writing the paper than finishing the project, we can set up an equation that states that x = 1.5y. We can then substitute 1.5y for x in the equation for the total number of hours, 9x + 9y, and simplify it to 9(1.5y + y). This simplifies to 13.5y and since y = x/1.5, we can substitute x/1.5 for y and get 13.5(x/1.5). Simplifying this equation, we get 9x, meaning that Glen spends 9x hours writing the paper and 9y/(x+y) hours finishing the project.

How many or each does Mr.
Paquette have?
Equation 1:
Equation 2:
Answer:
Let's assume that Mr. Paquette has x pencils.
From the problem, we know that for each pencil he has, he also has 3 pens. So the total number of pens he has is 3 times the number of pencils:
Number of pencils = x
Number of pens = 3x
The total number of pencils and pens combined is given as 8, so we can write:
x + 3x = 8
Simplifying, we get:
4x = 8
x = 2
Therefore, Mr. Paquette has 2 pencils and 3x2=6 pens.

assume that the number of calories in a mcdonald's egg mcmuffin is a normally distributed random variable with a mean of 290 calories and a standard deviation of 14 calories. what is the probability that a particular serving contains fewer than 300 calories? more than 250 calories? between 275 and 310 calories?
The probability that a particular serving contains fewer than 300 calories is 0.71, more than 250 calories is -2.86, between 275 and 310 calories is 0.7186.
To solve this problem, we need to use the normal distribution and the corresponding z-scores. We can find the z-score for a particular value of x (number of calories) using the following formula:
z = (x - μ) / σ
where μ is the mean, σ is the standard deviation, and x is the specific value we are interested in.
Probability of serving containing fewer than 300 calories:
z = (300 - 290) / 14 = 0.71
Using a standard normal distribution table or calculator, we find that the probability of a z-score being less than 0.71 is 0.7611. Therefore, the probability of a serving containing fewer than 300 calories is 0.7611.
Probability of serving containing more than 250 calories:
z = (250 - 290) / 14 = -2.86
Using a standard normal distribution table or calculator, we find that the probability of a z-score being greater than -2.86 is 0.9977. Therefore, the probability of a serving containing more than 250 calories is 0.9977.
For 275 calories:
z = (275 - 290) / 14 = -1.07
For 310 calories:
z = (310 - 290) / 14 = 1.43
Next, we use a standard normal distribution table or calculator to find the probability of z falling between -1.07 and 1.43. For example, using a standard normal distribution table, we can find that the probability of z falling between -1.07 and 1.43 is approximately 0.7186.
Therefore, the probability that a particular serving of McDonald's Egg McMuffin contains between 275 and 310 calories is approximately 0.7186, or 71.86%.

Each of the expressions has been simplified by using properties of exponents as shown below.
What is an exponent?In Mathematics, an exponent refers to a mathematical operation that is typically used in conjunction with an algebraic expression in order to raise a quantity to the power of another.
This ultimately implies that, an exponent is represented by the following mathematical expression;
bⁿ
Where:
the variables b and n are numerical values (numbers) or an algebraic expression.
n is referred to as a superscript or power.
By applying the multiplication and division law of exponents for powers to each of the expressions, we have the following:
(1.25 × 10⁷) + 63,000,000 = (1.25 × 10⁷) + (6.3 × 10⁷) = (1.25 + 6.3) × 10⁷ = 7.55 × 10⁷
12,000 + 7 × 10⁴ = 1.2 × 10⁴ + 7 × 10⁴ = (1.2 + 7) × 10⁴ = 8.2 × 10⁴

6 × 10⁸ ÷ 120 = 6 × 10⁸ ÷ 1.2 × 10² = (6 ÷ 1.2) × 10⁸⁻² = 5 × 10⁶
9 × 10¹² ÷ 4.5 × 10⁴ = (9 ÷ 4.5) × 10¹²⁻⁴ = 2 × 10⁸
1.3 × 10³ · 2,200 = 1.3 × 10³ × 2.2 × 10³ = (1.3 × 2.2) × 10³⁺³ = 2.86 × 10⁶
(6.3 × 10⁴) + 1.3 × 10⁴ = (6.3 + 1.3) × 10⁴ = 7.6 × 10⁴
3,400 · 2 × 10⁴ = 3.4 × 10³ × 2 × 10⁴ = (3.4 × 2) × 10³⁺⁴ = 6.8 × 10⁷
9.78 × 10⁵ - 732,000 = (9.78 - 7.32) × 10⁵ = 2.46 × 10⁵
3.5 × 10² · 2 × 10⁴ = (3.5 × 2) × 10²⁺⁴ = 7 × 10⁶
1.1 × 10⁸ ÷ 22,000 = 1.1 × 10⁸ ÷ 2.2 × 10⁴ = (1.1 ÷ 2.2) × 10⁸⁻⁴ = 0.5 × 10⁴ = 5 × 10³.

If a circle graph was constructed from the results, which lake activity has a central angle of 46.8°?
The lake activity with a central angle of 46.8° is waterskiing, since it is the lake activity chosen by 13% of the campers.
what is central angle ?
A central angle is an angle formed by two radii of a circle that intersect at its center. The central angle is measured in degrees and is used in circle graphs or pie charts to represent the proportion or percentage of each category in the data.
In the given question,
To find out which lake activity has a central angle of 46.8°, we first need to calculate the total number of campers who participated in the survey:
Total number of campers = 15 + 11 + 7 + 13 + 54 = 100
Next, we need to find the percentage of campers who chose each lake activity:
Percentage of campers who chose kayaking = (15/100) x 100% = 15%
Percentage of campers who chose wakeboarding = (11/100) x 100% = 11%
Percentage of campers who chose windsurfing = (7/100) x 100% = 7%
Percentage of campers who chose waterskiing = (13/100) x 100% = 13%
Percentage of campers who chose paddleboarding = (54/100) x 100% = 54%
Now we can use the formula for calculating the central angle of a circle graph:
Central angle = (Percentage/100) x 360°
For the lake activity with a central angle of 46.8°, we can set up the following equation:
(Percentage/100) x 360° = 46.8°
Solving for Percentage, we get:
Percentage = (46.8°/360°) x 100% = 13%
Therefore, the lake activity with a central angle of 46.8° is waterskiing, since it is the lake activity chosen by 13% of the campers.

Let ABC be an isosceles triangle at A, altitude AH
a) Prove that ∆AHB = AHC. From that, deduce the remaining equal factors of the two triangles.
b) Draw the medians BM and CN, they intersect at G. Prove that the three points A,G,H are collinear, prove that ∆GBC is equal
c) On the opposite ray of ray MH take point D such that M is mid point of HD, prove BC=2AD
For isosceles triangle we have proved a) ∆AHB = AHC b) AH is the median of ∆ABC c) BC = 2AD
a) To prove that ∆AHB = AHC, we need to show that the two triangles have equal sides and angles. Since ABC is an isosceles triangle at A, we know that AB = AC. Also, since AH is the altitude of the triangle, we know that it is perpendicular to BC. Therefore, angle AHB and angle AHC are both right angles.
Now, to prove that the triangles have equal sides, we need to show that HB = HC. Since AB = AC, we have:
[tex]AB^{2} = AC^2\\AB^2 - AH^2 = AC^2 - AH^2\\BH^2 = CH^2[/tex]
Therefore, HB = HC, and we have proved that ∆AHB = AHC.
From this, we can deduce that angle BHA = angle CHA, as they are opposite angles in congruent triangles. Also, we know that angle ABC = angle ACB, as it is an isosceles triangle. Therefore, angle ABH = angle ACH, and we have proved that ∆ABH = ∆ACH.
b) To prove that A, G, and H are collinear, we need to show that AH is the median of ∆ABC. Since ∆AHB = AHC, we know that HB = HC. Therefore, BG and CG are medians of the triangle, and they intersect at G.
Now, to prove that ∆GBC is equal, we can use the fact that medians of a triangle divide it into six equal triangles. Therefore, we have:
Area(∆GBC) = 2/3 * Area(∆BGC)
Area(∆GBC) = 2/3 * Area(∆ACG)
Area(∆GBC) = 2/3 * Area(∆ABG)
Since ∆ABH = ∆ACH, we know that the altitude from A to BC passes through H, which is the midpoint of BC. Therefore, AH is also the median of ∆ABC.
c) Let E be the midpoint of BC. Since AE is the median of the triangle, we know that it divides BC into two equal parts, so EC = EB. Let X be the midpoint of AD. Since M is the midpoint of HD, so:
HX = (1/2) * HD
HX = (1/2) * (2AD)
HX = AD
AX is parallel to DE so:
AB/AD = AE/AX
2 = AE/AX
Since EC = EB and HX = AD, so:
AE = EC + HX
AE = EB + HX
AE = 2HX
Therefore, substitute, simplify:
2 = 2HX/AX
2AX = 2HX
AX = HX
Since AX = HX, DX is also equal to HX, so:
AD = DX
Also, since AE = 2HX, so:
BC = 2AE
Substitute in HX = AD and AE = 2HX, so:
BC = 2AE
BC = 2(2HX)
BC = 4HX
BC = 4AD
Therefore, we have proved that BC = 2AD.

Taking the square root of both sides, we get:
x ≈ 19.79
Again, If a triangle is a right triangle, then the sum of the squares of the two shorter sides is equal to the square of the longest side.
[tex](x+3)^2 = (19.79)^2-(4)^2\\(x+3)^2= 391.64-16\\(x+3)^2= 225.64\\(x+3)= \sqrt225.64\\(x+3)= 15.021\\x = 15.021-3\\x = 12.021[/tex]

a small school has three foreign language classes, one in french, one in spanish, and one in german. how many of the 34 students enrolled in the spanish class are also enrolled in the french class?
The number of students enrolled in the Spanish class who are also enrolled in the French class is 0.
Let the number of students enrolled in French class be F
Let the number of students enrolled in Spanish class be S
Let the number of students enrolled in German class be G
From the given information, we have
S + F + G = Total number of students...... (1)
Total number of students = 34S = 34 - F - G...... (2)
Now, we need to find out how many students are enrolled in both Spanish and French classes. So, let us assume that x students are enrolled in both Spanish and French classes.
So, the total number of students in Spanish and French classes will be S + F - x (as x students are enrolled in both the classes).
But we are given that there are 34 students enrolled in the Spanish class. Hence, the above expression will be equal to 34.
Therefore, S + F - x = 34
Now, substituting the value of S from equation (2) we get,
34 - F - G + F - x = 34 or, - G - x = 0 or, x = - G
But x represents the number of students enrolled in both Spanish and French classes, which cannot be negative.
Hence, there are no students enrolled in the Spanish class who are also enrolled in the French class.

The difference between a sample statistic and the corresponding population parameter is known as the sampling error.
What is sampling error?Sampling error is the disparity between a statistic from a sample and a corresponding parameter from a population. Statistic and parameter are two crucial words in inferential statistics that are used to describe data. A statistic is used to calculate a parameter, which is a calculated value from the population, which is a large group of people or objects.
The variance between the mean of the population and the sample's mean is known as sampling error. The sample statistic that is used to estimate the population parameter may not be the same as the population parameter.
The discrepancy between these two values is referred to as sampling error. When a small sample is chosen from a larger population, a sampling error is created.
Therefore, The sampling error is the discrepancy between a sample statistic and the equivalent population parameter.

The weight of a compact car is approximately 1,354 kilograms. Express the weight of the car in grams
The weight of the compact car, which is approximately 1,354 kilograms, can be converted to 1,354,000 grams.
In the metric system, "kilo" means thousand, so 1 kilogram is equal to 1000 grams. To convert from kilograms to grams, we simply multiply the weight in kilograms by 1000.
In this case, the weight of the compact car is given in kilograms as 1,354. To convert to grams, we multiply by 1000 to get:
1,354 kg x 1000 g/kg = 1,354,000 g
Therefore, the weight of the compact car in grams is approximately 1,354,000 grams.
The weight of an object is a measure of the force with which gravity pulls on the object. The unit of weight in the metric system is the newton (N), but kilograms (kg) are commonly used as a unit of mass and weight in everyday life. The conversion between mass and weight depends on the local acceleration due to gravity, which is approximately 9.81 m/s^2 at the Earth's surface.
