4 miles per hour
Step-by-step explanation:Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.
Proportion
First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.
This creates the proportion [tex]\frac{12miles}{3hours}[/tex]So, the rate we are given is 12/3.
Unit Rate
To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.
12/3 equals 43/3 equals 1So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.
Graph
Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

A square pyramid on top of a rectangular prism. The rectangular prism has a length of 4 meters, width of 4 meters, and height of 4 meters. The square pyramid has triangular sides that have a height of 3 meters and side length of 5 meters. Compare the surface area of the composite figure to the surface area to the combined surface areas of the figures if they were separated. The composite surface area would be the surface area of the rectangular prism plus the surface area of the square pyramid considered separately. You should not count the pyramid’s as part of the composite figure’s surface area.

i think it is (-1,0)
Step-by-step explanation:
if you graphed the points this option makes the most sense
Explanation: The angles that would make up the top left and right corners of the parallelogram would be (4,0) and (2,0). Because (0, -2) is the bottom left angle, to make this shape a full parallelogram, the y-coordinate of the other angle would have to also be -2, and it would have to be to the right of the origin so the figure does not look sloppy. To add on to this, none of the given x-coordinates are negative, so the fourth point should not have a negative x-coordinate. That would instantly get rid of A, B, and C. Therefore, your answer would be D, or (0, -2).

Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.
