Kareem estimated the height of his office building to be 35 ft . The actual height of his office building is 38 ft. Find the abs
Leno4ka [110]

Answer:

the absolute error is 3 ft and percent error of Tony's estimate is 789.4%.

Step-by-step explanation:

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:

The height of his office building - the actual height of his office building

38ft-35ft

=3ft

The absolute error = 3ft.

Now, to get the percent error of Tony's estimate:

3

------   x    100

38

=7.894x100

=789.4

789.4%

Therefore, the absolute error is 3 ft and percent error of Tony's estimate is 789.4%.

The diagram shows a right triangle and three squares. The area of the largest square is 55 units.
Keith_Richards [23]

Answer:

A

B

C

Step-by-step explanation:

Well the sides of the smaller squares have to be greater than the biggest when put together.

a + b > c

So we need to find the square root of 55.

\sqrt{55}

≅ <u>7.4</u>

<u />

Now for option A)

srt ⇒ 12 ≅3.5

srt ⇒ 43 ≅ 6.6

3.5 + 6.6 = <u>10.1</u>

So option A is correct.

Option B)

srt ⇒ 14 ≅ 3.7

srt ⇒ 40 ≅ 6.3

3.7 + 6.3 = <u>10</u>

So option B is also correct.

Option C)

srt ⇒ 16 = 4

srt ⇒ 37 ≅ 6.1

4 + 6.1 = <u>10.1</u>

So option C is also correct.

<em>Therefore,</em>

<em>all options are correct.</em>

<em />

<em>Hope this helps :)</em>
