The error percentage is 4.13%.

<h2>Error percentage</h2>

The amount of mistakes is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Given

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

The actual height is 75.50 in.

<h3>To find </h3>

The error percentage.

<h3>How to find the error percentage?</h3>

We know the formula for the error percentage.

\rm \% Error = \dfrac{Measured \ value- Actual\ value}{Actual\ value} * 100\\\\ \% Error = \dfrac{78.25 - 75.50}{78.75}*100\\\\ \% Error = \dfrac{3.25}{78.75}*100\\\\ \% Error = 0.0413*100\\\\ \% Error = 4.13 \%

The error percentage is 4.13%.

More about the error link is given below.

Answer:

Let fertilizer be F

and peat moss be P

since F is proportional to P

F = kP

where, k = constant of proportionality

k = F/P

putting in the values,

k = (3/4) /12

k = 3/4 * 1/12

k = 1/16

Therefore the constant of proportionality is 1/16.

The ancient Greeks could bisect an angle using only a compass and straightedge.A. TrueB. False
Gala2k [10]

Answer: True.

The ancient Greeks could bisect an angle using only a compass and straightedge.

Step-by-step explanation:

The ancient Greek mathematician <em>Euclid</em> who is known as inventor of geometry.

The Greeks could not do arithmetic. They had only whole numbers. They do not have zero and negative numbers.

Thus, Euclid and the another Greeks had the problem of finding the position of an angle bisector.

This lead to the constructions using compass and straightedge. Therefore, the straightedge has no markings. It is definitely not a graduated-rule.

As a substitute for using arithmetic, Euclid and the Greeks learnt to solve the problems graphically by drawing shapes .
