Answer:
Building's actual height 32 meters
Building's shadow height 20 meters
Person's shadow height 1.2 meters
Person's actual height = ?
Find the person's actual height:
This is a proportion problem.
Actual height to shadow height
Building = Person
32 : 20 = x : 1.2
32 * 1.2 = 20 * x
38.4 = 20x
38.4/20 = 20x/20
1.92 = x
The person's actual height is 1.92 meters long.
32 : 20 = 1.92 : 1.2
32/20 = 1.60
1.92/1.2 = 1.60
Step-by-step explanation:
The requried reasonable prediction for the number of people who would jog regularly in the community is 1350.
Proportionality is the relationship between two or more sets of values, and it describes how these values are related to each other.
If 3 out of 7 people jog on a regular basis, then the fraction of people in the community who jog on a regular basis is:
3/7
To predict the number of people who would jog regularly in the community, we can multiply this fraction by the total number of people in the community:
(3/7) * 3150 = 1350
Therefore, a reasonable prediction for the number of people who would jog regularly in the community is 1350.

The slope of line for the points is -5/8.
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
given:
We have the Points (–6, 8), (2, 3).
So, the slope is
m = (3- 8)/ (2- (-6))
m = -5 / (2+6)
m = -5 / 8
Thus, the Slope is -5/8.

Answer:
Step-by-step explanation:
Slope = y/x
y1-y2/x1-x2=slope of 2 points
8-3/-6-2 = 5/-8 which equals -5/8 or -.625.
