if a qantas 787-9 with 285 passengers and 14 crew flew 7,536 miles from los angeles, california to sydney australia, how many revenue passenger miles (rpm) were flown on this flight?
The number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.
Revenue Passenger Miles (RPM) is a measure of how much passenger traffic an airline is serving, and is calculated by multiplying the number of revenue passengers (passengers paying a fare) by the distance travelled in miles. For this flight, the number of RPM is calculated as follows:
RPM = (Number of Revenue Passengers) x (Distance Travelled in Miles)
RPM = (285 Passengers) x (7,536 Miles)
RPM = 2,150,960 Miles
Therefore, the number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.

solve for x and show full work
Answer:
x = 8
Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion , that is
[tex]\frac{RT}{WU}[/tex] = [tex]\frac{RS}{WV}[/tex] ( substitute values )
[tex]\frac{6x+15}{28}[/tex] = [tex]\frac{108}{48}[/tex] ( cross- multiply )
48(6x + 15) = 28 × 108 = 3024 ( divide both sides by 48 )
6x + 15 = 63 ( subtract 15 from both sides )
6x = 48 ( divide both sides by 6 )

a 39 3939-meter ladder is sliding down a vertical wall so the distance between the bottom of the ladder and the wall is increasing at 10 1010 meters per minute. at a certain instant, the bottom of the ladder is 36 3636 meters from the wall. what is the rate of change of the distance between the top of the ladder and the ground at that instant (in meters per minute)?
The distance between the top of the ladder and the ground is decreasing at a rate of 10 meters per minute.
Let's call the distance between the bottom of the ladder and the wall as "x".
At a certain instant, x = 3636 meters
The rate of change of x with respect to time is 10 meters per minute, so dx/dt = 10 m/min.
At that same instant, the height of the ladder above the ground can be expressed as
h = (3939 - x)
since the ladder is 3939 meters long
The rate of change of h with respect to time can be found using the chain rule of differentiation.
dh/dt = dh/dx * dx/dt = -10 m/min
So, at the instant when the bottom of the ladder is 3636 meters from the wall, the rate of change of the distance between the top of the ladder and the ground is -10 meters per minute. This means that the distance between the top of the ladder and the ground is decreasing at a rate of 10 meters per minute.

One of your friends wants to buy a pair of binoculars to look at the birds and animals, however she cannot afford the R4999 at once. She pays a deposit of R999 and the rest over 3 years using simple interest.
What is the name given to this type of transaction?
The type of transaction described in the problem is called an installment purchase.
What is the simple interest?
Simple interest is a type of interest that is calculated on the principal amount of a loan or investment for a specific period of time.
The type of transaction described in the problem is called an installment purchase. In this type of transaction, a buyer pays a deposit at the time of purchase and then makes periodic payments, typically over a fixed period of time, until the full purchase price is paid off. In this case, the buyer pays a deposit of R999 and then pays off the remaining balance over a period of 3 years using simple interest.
To calculate the total amount that the buyer will pay over the 3-year period, we need to calculate the amount of interest that will be charged on the remaining balance. Since simple interest is being used, we can use the formula I = Prt, where I is the interest, P is the principal (the remaining balance), r is the interest rate, and t is the time period.
Assuming an annual interest rate of, for example, 5%, the interest charged on the remaining balance of R4000 (the original price minus the deposit) over 3 years would be:
I = Prt
I = 4000 * 0.05 * 3
I = R600
So the total amount that the buyer will pay over the 3-year period is:
R999 (deposit) + R4000 (remaining balance) + R600 (interest) = R5599
the total cost of the binoculars over the 3-year period will be R5599.
Hence, The type of transaction described in the problem is called an installment purchase.

how much time do students spend on the internet? we collect data from the 32 members of our ap statistics class and calculate the mean amount of time that each student spent on the internet yesterday.
It would be appropriate to construct a t-interval to estimate the population mean.
To determine whether it is appropriate to construct a t interval to estimate the population means, we need to consider if the sample size is large enough and if the population standard deviation is known.
If the sample size is less than 30 and the population standard deviation is not known, then it would be appropriate to use a t-interval.In this case, the sample size is 32, which is large enough to assume that the sample mean is an accurate representation of the population mean.
However, the population standard deviation is not known, so it would be appropriate to use a t interval. The t interval can be calculated using the sample mean, sample standard deviation, and degrees of freedom, which is the sample size minus 1.
The t interval will provide a range of values that we can be confident the population mean falls within, given the sample mean and variability.

The legs of a right triangle are 5 cm and 12 cm long. Find the lengths, to the
nearest tenth, of the segments into which the bisector of the right angle divide
the hypotenuse.
Answer: The hypotenuse are both 13 cm
Step-by-step explanation:
The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
So, in this case:
c^2 = a^2 + b^2
c^2 = 5^2 + 12^2
c^2 = 25 + 144
c^2 = 169
c = √169
c = 13
So the length of the hypotenuse is 13 cm.
Next, we can use the Pythagorean theorem to find the length of the segments into which the bisector of the right angle divides the hypotenuse. Let's call the length of the segments x. Then, the segments form two right triangles with legs of length x and (13-x)/2.
Using the Pythagorean theorem on each triangle, we have:
x^2 + ((13-x)/2)^2 = 13^2
x^2 + (13-x)^2/4 = 169
x^2 + (13^2 - 2x(13) + x^2)/4 = 169
x^2 + (13^2 - 2x(13))/4 = 169
x^2 + (169 - 26x)/4 = 169
x^2 + 169 - 26x = 676
x^2 - 26x + 507 = 0
Now, we can use the quadratic formula to find x:
x = (-b ± √(b^2 - 4ac)) / 2a
a = 1, b = -26, c = 507
x = (26 ± √(26^2 - 4 * 1 * 507)) / 2 * 1
x = (26 ± √(676)) / 2
x = (26 ± 26) / 2
x = 26 / 2
x = 13
So, the lengths of the segments into which the bisector of the right angle divides the hypotenuse are both 13 cm, to the nearest tenth.

a box contains seven 40-w bulbs, five 60-w bulbs, and six 75-w bulbs. if bulbs are selected one by one in random order, what is the probability that at least two bulbs must be selected to obtain one that is rated 75 w?
The probability that at least two bulbs must be selected to obtain one that is rated 75W is 2/3.
Number of 40W bulbs = 7
Number of 60W bulbs = 5
Number of 75W bulbs = 6
We are to find the probability that at least two bulbs must be selected to obtain one that is rated 75 w
Let's say the x is the event in which at least 2 bulbs must be selected to obtain one that is rated 75W and y is the event in which just one bulb was selected which is rated 75 W
So, P(x) = 1 - P(y)
P(x) = 1 - 6/(7 + 5 + 6)
P(x) = 1 - 6/18
P(x) = 1 - 1/3
P(x) = 2/3
Hence, the probability that at least two bulbs must be selected to obtain one that is rated 75W is 2/3.
