l3r-15l if r<5
SOLVE NOW PLEASE
Answer:
-3r + 15 ---> answer
Step-by-step explanation:
r < 5
You are going to multiply both sides with 3. The reason being is that 3 is a positive number and the equality sign will not change if you use +3.
3r < 15
Now, subtract 15 from both sides, you will get this:
3r < 15
-15 -15
-------------
3r — 15 < 0
Lastly, using the Modulus function, we are going to add a negative sign to the content of our previous step because it's already negative.
So, -3r + 15 is the final solution if r < 5 in the given equation of l3r-15l

AB and CD intersect at point O, ∠ACO ≅ ∠DBO, and BO ≅ CO . Prove that △ACO ≅ △DBO. Plz Help Me... Thanks
Since ∠COA and ∠BOD are vertical angles, they are congruent.
You are also given that ∠ACO ≅ ∠DBO and BO ≅ CO.
By ASA (Angle-Side-Angle) congruency, you know that △ACO ≅ △DBO
The proof is shown below:
What is congruency of Triangles?If the three angles and the three sides of a triangle are equal to the corresponding angles and the corresponding sides of another triangle, then both the triangles are said to be congruent.
In Δ PQR and ΔXYZ, as shown below, we can identify that PQ = XY, PR = XZ, and QR = YZ and ∠P = ∠X, ∠Q = ∠Y and ∠R = ∠Z. Then we can say that Δ PQR ≅ ΔXYZ.
What is ASA congruency criteria?ASA criterion stands for Angle-Side-Angle criterion. Under the ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.
Given:
∠ACO ≅ ∠DBO, and BO ≅ CO
as, ∠COA =∠BOD (vertically opposite angles)
∠ACO ≅ ∠DBO ( given)
BO ≅ CO ( given)
So, By ASA (Angle-Side-Angle) congruency, △ACO ≅ △DBO

Find the slope of this graph
The US Department of Health and Human Services wants to know whether the healthcare system is achieving its goals in Virginia. Much information about
healthcare comes from patient records, but that source doesn't allow us to compare people who use health services with those who don't. Therefore, the US
Department of Health and Human Services conducted the Virginia Health Survey, which was used to interview a random sample of 65,439 people who live in
the state of Virginia.
Part A: What is the population for this sample survey? What is the sample? (4 points)
Part B: The survey found that 71% of males and 88% of females in the sample had visited a general practitioner at least once during the past year. Do you
think these estimates are close to the truth about the entire population? Explain. (6 points)
Answer:
Part A: All the residents of the state of Virginia make up the population, while the sample is the number of those interviewed–65,439 people.
Part B: No
Step-by-step explanation:
Part A: In statistical analysis, the population refers to the study area of the research; and in this case– the state of Virginia. While the sample represents a considerable representation of the population in the survey.
Part B: No because we are told The US Department of Health and Human Services used a random sample, not a non-random sampling technique; which implies that the feedback was random and may not likely be close to the truth about the entire population.

PLZ ANSWER ACCURATELY AND QUICKLY WILL MARK BRALINLIEST
Answer:
Si se tiene en cuenta que la velocidad de la luz en el vacío es de 299.792 km/s. La distancia existente entre el 'astro rey' y la Tierra es de unos 149,6 millones de kilómetros, una pequeña operación matemática indica que la luz del Sol tarda aproximadamente 8 minutos y 19 segundos en llegar a nuestro planeta.
Step-by-step explanation:
It takes light from the Sun about 500 seconds, or 8 minutes and 20 seconds, to reach Earth.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
To find the time it takes for light to travel from the Sun to Earth,
We can use the formula:
Time = distance/speed
where distance is the distance from the Sun to Earth and speed is the speed of light.
Plugging in the given values.
Time = (1.5 × 10^11 meters) / (3 × 10^8 meters per second)
Simplifying.
time = 500 seconds

Step-by-step explanation:
x=0.5, y=7
x=1, y=14
x=1.5, y=21
x= 2, y=28
Let’s take the first equation.
y = 14x
y = 14(0.5) = 7
When x is 0.5, y is 7.
y = 14(1) = 14
When x is 1, y is 14.
y = 14(1.5) = 21
When x is 1.5, y is 21.
y = 14(2) = 28
When x is 2, y is 28.

In 2021, Ryan Management collected rent revenue for 2022 tenant occupancy. For financial reporting, the rent is recorded as deferred revenue and then recognized as revenue in the period tenants occupy rental property. For tax reporting, the rent is taxed when collected in 2021. The deferred portion of the rent collected in 2021 was $66 million. Taxable income is $260 million in 2021. No temporary differences existed at the beginning of the year, and the tax rate is 25%. Prepare the appropriate journal entry to record income taxes in 2021.

A certain forest covers an area of 2900 km. Suppose that each year this area decreases by 8.5%. What will the area be after 8 years?
Use the calculator provided and round your answer to the nearest square kilometer.
Answer:
1425 square kilometer.
Step-by-step explanation:
2900 - 8.5% = 2653.5
2653.5 - 8.5% = 2427.9525
2427.9525 - 8.5% = 2221.5765375
2221.5765375 - 8.5% = 2032.74253181
2032.74253181 - 8.5% = 1859.95941661
1859.95941661 - 8.5% = 1701.8628662
1701.8628662 - 8.5% = 1557.20452257
