Answer: 99 different faces
Step-by-step explanation:
Since a witness can clearly remember the hairline and the eyes and eyebrows of a suspect, and the
basic identification kit contains 195 hairlines, 99 eyes and eyebrows, the number of different faces that can be produced with this information will be 99
Answer:
4,000 L/h
Step-by-step explanation:
First we'll find the amount of the change.
18,000 - 6,000 = 12,000 L
The time of the volume change was 3 hours: 0230 - 0530
Since we're looking for liters per hour, we will divide the liters (12,000) by the hours (3)
12,000/3 = 4,000 L/h
Answer:
y = -2x -3
Step-by-step explanation:
The line crosses the y-axis at -3, so that is the y-intercept.
It has a "rise" of -2 units for each "run" of 1 unit, so the slope is -2. (For example, from point (-1, -1) to point (0, -3).)
The slope m and y-intercept b are used in the slope-intercept form of the equation of a line:
y = mx + b
For the values this line has, the equation is ...
y = -2x -3
