Answer:
The absolute error is <u>4 ft</u> and percent error of Tony's estimate is <u>9.8%</u>.
Step-by-step explanation:
Given:
Tony estimated the height of his office building to be 45ft. The actual height of his office building is 41ft.
Now, to find the absolute error and the percent error of Tony's estimate.
The height of his office building = 45ft.
The actual height of his office building = 41 ft.
So, to get the absolute error:
<em>The height of his office building - the actual height of his office building</em>

The absolute error = 4 ft.
Now, to get the percent error of Tony's estimate:



<em>Percent error of Tony's estimate rounding to nearest tenth = 9.8%.</em>
Therefore, the absolute error is 4 ft and percent error of Tony's estimate is 9.8%.
Answer:
Western U gets 20 million
Norther U gets 40 million
Eastern U gets 50 million
Step-by-step explanation:
We need to find the amount each university gets.
Let
Northern U get n
Western U get w
Eastern U get e
We can write equations from the given word problem:
n + w + e = 110
and
n = 2w
e = n + w - 10
Putting 2nd in 3rd, we get:
e = 2w + w - 10
e = 3w - 10
Now putting this and 2nd in first, we solve for w:
n + w + e = 110
2w + w + 3w - 10 = 110
6w = 120
w = 20
AND n = 2 (20) = 40
AND e = 3(20) - 10 = 50
So,
Western U gets 20 million
Norther U gets 40 million
Eastern U gets 50 million
