Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in. To the nearest tenth of a percent, wha
Vinil7 [7]

Answer  

Find out the  percent error in Annie's estimate .

To prove

Formula

Percentage\ error = \frac{error\times 100}{exact\ value}

As  error = approx value -  exact value

As given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

approx value = 78.25 in.

actual value = 75.50 in.

error = 78 .25 - 75 .50

        = 2.75

put in the formula

Percentage\ error = \frac{2.75\times 100}{75.50}

Percentage\ error = \frac{27500}{7550}

Percentage error = 3.64 % (approx)

Therefore the Percentage error be 3.64 % (approx).

The measure of RST can be represented by the expression (6x + 12)°.
Valentin [98]

Answer:

The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m -----> equation A

m -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

6x-3x=78\°-24\°

3x=54\°

x=18\°

The measure of angle RST is equal to

m
