Answer:
Sure, here are the answers to your questions:
The constant of proportionality is 45. This is because the ratio of distance to time is always 45. For example, 90/2 = 45, 135/3 = 45, 225/5 = 45, and 270/6 = 45.
The unit rate is 45 miles per hour. This is because the constant of proportionality is 45, and the units of time are hours and the units of distance are miles.
The equation that represents the relationship between time, t, and distance, d, is d = 45t. This is because the constant of proportionality is 45, and the equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality.
Here are the steps that I used to solve the problem:
I first looked at the table and noticed that the ratio of distance to time was always the same. This is a clue that the relationship between distance and time is proportional.
I then calculated the constant of proportionality by dividing the distance by the time for each pair of values. For example, I divided 90 by 2 to get 45, 135 by 3 to get 45, 225 by 5 to get 45, and 270 by 6 to get 45.
I then used the constant of proportionality to write a unit rate. The unit rate is the constant of proportionality divided by the units of time. In this case, the constant of proportionality is 45 and the units of time are hours. Therefore, the unit rate is 45 miles per hour.
I then used the constant of proportionality to write an equation. The equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality. In this case, the constant of proportionality is 45, so the equation is d = 45t.

This is science just please look at the pic and answer if you know don’t answer if you don’t know don’t steal points
Answer:
1) a body of air with horizontally uniform temperature, humidity, and pressure.
2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.
3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.
4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.
5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.

If p 0, and p + q = r, which statement about r is true?
a. |r| = |q|
b. r > 0
c. r |q|
If the question comes out with missing symbols or sentences, do not answer it. I will try to fix it.
Answer:
A
Step-by-step explanation:
Since p is very much less than q, meaning that even if q is added to p, r would still be negative. So b is incorrect. C isn't an equation, so the answer is A.

A
