¿Cuánto es 80% de 120 000?
Answer:
96,000
Step-by-step explanation:
.8 x 120,000 = 96,000
mueves el decimal sobre el porcentaje que deseas encontrar, luego lo multiplicas por el total. por ejemplo quiere 80% entonces mueves el decimal para que sea .8 o si quierias 55% entonces es .55 y el total es el 120,000 el numero que tienes. (:
Answer:96000
Step-by-step explanation:
120000/x=100/80
(120000/x)*x=(100/80)*x - we multiply both sides of the equation by x
120000=1.25*x - we divide both sides of the equation by (1.25) to get x
120000/1.25=x
96000=x
x=96000

The center is O. The circumference is 28. 6 centimeters. Use 3. 14 as an approximation for pi
The diameter of the given circle with a circumference of 28.6 centimeters is approximately 9.11 cm.
The circumference of a circle is given by the simple formula: C = πd, where C is the circumference, π is the constant pi and d is the diameter of the circle.
Given that the circumference of the circle is 28.6 cm, we can use the formula to find the diameter:
28.6 = πd
d = 28.6/π
Using 3.14 as an approximation for π, we get:
d ≈ 28.6/3.14 ≈ 9.11

Let T be a unitary operator on a finite-dimensional complex inner product space V. Consider a T-invariant subspace W of V. Show that (a) (10 points) T (W)- W; b)(15 points) Wl is T-invariant.
Since T is a unitary operator which is invertible as well as inverse of T is also unitary. So T(W)=W and Tv∈W⊥, so Wl is T-invariant.
(a) To show that T(W)⊆W, let w∈W. Since W is T-invariant, we have T(w)∈W.
Therefore, T(W)⊆W. To show that W⊆T(W), let w∈W.
Since T is unitary, it is invertible, and its inverse T⁻¹ is also unitary.
Since T is unitary, we have ||T(w)||=||w||.
Therefore, T⁻¹(w)∈W. It follows that T(T⁻¹(w))=w∈T(W), so W⊆T(W).
Therefore, T(W)=W.
(b) Let v∈Wl, i.e., v∈W⊥. We want to show that Tv∈Wl, i.e., Tv∈W⊥. To do this, let w∈W. Then we have
⟨Tv,w⟩=⟨v,\(T^{*(w)\)⟩=⟨v,T⁻¹(w)⟩=0
since T⁻¹(w)∈W by part (a) and v∈W⊥.
Therefore, Tv∈W⊥, so Wl is T-invariant.

Determine if L is the midpoint of segment MN. Justify your answer using sound mathematical reasoning.
Answer: L isn't the midpoint of segment MN.
Step-by-step explanation:
NL+LM=NM
6x-5+2x+3=4x+9
8x-2=4x+9
8x-2+2=4x+9+2
8x=4x+11
8x-4x=4x+11-4x
4x=11
Divide both parts of the equation by 2:
2x=5.5
NL=6x-5
NL=(2x)(3)-5
NL=(5,5)(3)-5
NL=16.5-5
NL=11.5
LM=2x+3
LM=5.5+3
LM=8.5
NL≠LM
Hence, L isn't the midpoint of segment MN.
In summary, based on the given lengths and mathematical reasoning, we have determined that point L is the midpoint of segment MN because the lengths of NL and LM are equal when x = 2.
We must compare the lengths of the two segments NL and LM and see if they are identical in order to establish whether point L is the midpoint of segment MN.
NL = 6x - 5
LM = 2x + 3
The lengths of NL and LM ought to be equal if L is the middle of segment MN. To put it another way, NL and LM ought to be equal.
Constructing the equation
6x - 5 = 2x + 3
Now, solve for x:
6x - 2x = 3 + 5
4x = 8
x = 2
As soon as we know the value of x, we can put it back into the NL and LM formulas to get their lengths at x = 2:
NL = 6x - 5 = 6 * 2 - 5 = 12 - 5 = 7
LM = 2x + 3 = 2 * 2 + 3 = 4 + 3 = 7
The lengths of NL and LM are both 7 units.
Point L is in fact the middle of segment MN because both segments NL and LM have similar lengths.

Station A and Station B are 120 miles apart. A train traveling from station A to station B travels exactly 1/3 of the distance when it is held up and stops for 16 minutes. When the train continues its journey,the engineer increases its avarage speed by 15 mph so that the train will arive at station B on schedule. Find the avarage speed of the train before it stopped for minutes
The required average speed of the train is calculated to be 60 mph, when the train travels certain distance and stops.
Distance between station A and station B is given as 120 miles.
A train traveling from station A to station B travels exactly 1/3rd of the distance when it is held up and stops for 16 minutes.
Let, its average speed was x mph.
Then, total time taken if it didn't stop = 120/x h
Now, before stop it took time = ( 1/3 × 120)/x h = (40/x) h
After stop the time it took = 80/(x + 15) h
i.e, 40/x + 16/60 + 80/(x+15) = 120/x
⇒ 80/(x + 15) + 8/30 = 80/x
⇒ 80(1/x - 1/(x + 15)) = 8/30
⇒ 10 × (15/x² + 15x) = 1/30
⇒ x² + 15x = 10 × 15 × 30
⇒ x² +15x - 450 = 0
⇒ x² +75x -60x - 450 = 0
⇒ (x+75)(x-60) = 0
⇒ x = 60 or, x = -75
As speed cannot be negative, the average speed is 60 mph.

THIS is in abrieviations.
a hotel near the university always fills up on the evening before football games history has shown that when the hotel is fully booked, the number of last minute cancellations has a mean of five and a standard deviation of three. the average room rate is $80. when the hotel is overbooked, the policy is to find a room in a nearby hotel and to pay for the room for the customer. this is usually costs the hotel approximately $200 since rooms booked on such late notice or expensive. how many rooms should the hotel overbooked?
The hotel should overbook enough rooms to maximize revenue without incurring expensive costs due to last-minute cancellations. To determine the optimal number of rooms to overbook, consider the following:
1. The average number of cancellations is 5 with a standard deviation of 3.
2. The average room rate is $80.
3. The cost of accommodating overbooked customers in a nearby hotel is $200.
Using these figures, the hotel can calculate the expected revenue for each room overbooked, while considering the risk of cancellations. The best approach is to use a probabilistic model, such as the normal distribution, to estimate the optimal number of rooms to overbook based on these statistics.
A detailed analysis would require further calculations and simulations, which are beyond the scope of this answer. However, a basic guideline for the hotel would be to overbook only a few rooms (e.g., 1-3) to minimize the risk of incurring the high cost of accommodating customers in nearby hotels while still maximizing the revenue from potential cancellations.

The smooth side of the film is the side that interacts with the X-ray radiation and receives the image, while the emulsion side contains the light-sensitive crystals that react to the radiation.
Placing the smooth side towards the throat ensures that the image is sharp and clear, as the X-ray beam travels through the teeth and soft tissues before reaching the film.
After processing, the exposed areas of the film turn dark, representing the captured X-ray image, while the unexposed areas remain light or clear.

The scores for the Algebra 2 CFE are normally distributed with a mean score of 43 and
a standard deviation of 3.8. If you scored 47 on the test, what percentage of test takers
scored lower than you? Do not round your answer. [percent]
Answer:
85.375%
Step-by-step explanation:
We would be using the z-score formula which is
z = (x-μ)/σ, where
x is the raw score,
μ is the population mean, and
σ is the population standard deviation.
In the question, we are given:
x is the raw score = 47
μ is the population mean = Mean score = 43
σ is the population standard deviation = 3.8
z = (x-μ)/σ
z = (47- 43)/ 3.8
z = 4/3.8
z = 1.0526315789
The z score = 1.0526315789
Checking my z score on my normal distribution table,
The percentage of test takers that scored lower than you =
[1 - P(x>Z)] × 100
= ( 1 - 0.14625) × 100
= 0.85375 × 100
= 85.375%
Therefore, the percentage of test takers that scored lower than you is 85.375%
Solve dy/dx = xy, y(0) = 2. Find the interval, on which the solution is defined.
Answer:
The interval on which the solution is defined depends on the domain of the exponential function. Since e^((1/2)x^2 + ln(2)) is defined for all real numbers, the solution is defined on the interval (-∞, +∞), meaning the solution is valid for all x values.
Step-by-step explanation:
o solve the differential equation dy/dx = xy with the initial condition y(0) = 2, we can separate the variables and integrate both sides.
Starting with the given differential equation:
dy/dx = xy
We can rearrange the equation to isolate the variables:
dy/y = x dx
Now, let's integrate both sides with respect to their respective variables:
∫(dy/y) = ∫x dx
Integrating the left side gives us:
ln|y| = (1/2)x^2 + C1
Where C1 is the constant of integration.
Now, we can exponentiate both sides to eliminate the natural logarithm:
|y| = e^((1/2)x^2 + C1)
Since y can take positive or negative values, we can remove the absolute value sign:
y = ± e^((1/2)x^2 + C1)
Next, we consider the initial condition y(0) = 2. Substituting x = 0 and y = 2 into the solution equation, we get:
2 = ± e^(C1)
Here, we see that e^(C1) is positive since it represents the exponential of a real number. So, the ± sign can be removed, and we have:
2 = e^(C1)
Taking the natural logarithm of both sides:
ln(2) = C1
Now, we can rewrite the general solution with the determined constant:
y = ± e^((1/2)x^2 + ln(2))
