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>

45\ ft-41\ ft\\=4\ ft.

The absolute error = 4 ft.

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

\frac{4}{41} \times 100

=0.0975\times 100

=9.75\%.

<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%.

mart [117]

3 times 5 times 2.5 = $37.5

3 x 5 =15

15 x 2.5 =37.5

37.5 x 2 = 75 for both of them

I don't know if this is right or not, but that's how I would solve it!

If you invested $500 at 5% simple interest for 2 years, how much interest do you earn? Show work and answer in
givi [52]

Answer:

$50

$30.88

I will invest in simple interest as the interest there is more.

Step-by-step explanation:

If I invested $500 at 5% simple interest for 2 years, then the interest that I will get will be given by the formula

I = P \times \frac{rt}{100}, where P is the invested principal, r is the APR and t is the time in years.

So, in our case, I = 500 \times \frac{5 \times 2}{100} = 50 dollars. (Answer)

Now, if I invest $500 at 3% compound interest compounded monthly for 2 years.

Now, using the formula of compound interest we have

I = P(1 + \frac{r}{n \times 100} )^{tn} - P, where r is the APR and n is the number of times in a year the principal is compounded.

In our case, I = 500(1 + \frac{3}{12 \times 100} )^{2 \times 12} - 500 = 30.88 dollars. (Answer)

Therefore, I will invest in simple interest as the interest there is more. (Answer)
