Answer:
Explanation:
Let x be the age of the person who enter the room
(18 + 25 + 18 + 21 + 16 + x)/6 = 25
(77 + x)/6 = 25
77 + x = 25(6)
77 + x = 150
x = 150 - 77
x = 73
Answer:
36 milliliters of rain.
Step-by-step explanation:
The rate at which rain accumluated in a bucket is given by the function:

Where r(t) is measured in milliliters per minute.
We want to find the total accumulation of rain from <em>t</em> = 0 to <em>t</em> = 3.
We can use the Net Change Theorem. So, we will integrate function <em>r</em> from <em>t</em> = 0 to <em>t</em> = 3:

Substitute:

Integrate:

Evaluate:

36 milliliters of rain accumulated in the bucket from time <em>t</em> = 0 to <em>t</em> = 3.
Answer:
90
Step-by-step explanation:
1/3 BH = 1/3(30)(9) = 90
Answer:
2
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1) where (x1, x2) and (y1, y2) are points on the line
Plug in the points A (-3, -2) and B (1, 6)
(y2 - y1) / (x2 - x1)
(6 + 2) / (1 + 3)
8 / 4
= 2
So, the slope of line segment AB is 2.
This question is really confusing.
