Answer from: isabellainksow87vn

Assuming that the dimensions are proportional, we have the following relationship:

$\frac{x}{5+\frac{1}{3}} = \frac{54}{2}$

Where,

x: approximate height of the statue

Clearing the value of x we have:

$x=\frac{54}{2}(5+\frac{1}{3})$

x = 144

On the other hand, we know that:

1feet = 12inches

Then, in relative terms, the relationship between the heights of the statue is:

$\frac{144-(143+\frac{9}{12}}{143+\frac{9}{12}}(100)$

1.7 %

The approximate height of the statue is:

x = 144

The difference with respect to the actual height is 1.7%.

The approximate height is 0.251 inches close to the statue's actual height of 143 feet, 9 inches from heel to top of head .

Step-by-step explanation:

Given :

The length of the statue's right arm is 54 feet.

The student's right arm is 2 feet long and her height is 5 and one third feet.

To Find : How close is the approximate height to the statue's actual height of 143 feet, 9 inches from heel to top of head?

Solution:

Let the height of the statue be x

The length of the statue's right arm is 54 feet.

The student's right arm is 2 feet long

Ratio of their arms length = 54:2

Height of girl = $5\frac{1}{3} =\frac{16}{3}$

Ratio of their heights = $x: \frac{16}{3}$

So, $\frac{x}{\frac{16}{3}}=\frac{54}{2}$

$x=\frac{16}{3} \times \frac{54}{2}$

$x=8 \times 18$

x=144

So, the approximate height is 144 feet.

Actual height of statue is 143 feet, 9 inches = $143 + 9 \times 0.0833333=143.749$

So, the difference between approximate height and actual height:

= 144-143.749

=0.251

Hence the approximate height is 0.251 inches close to the statue's actual height of 143 feet, 9 inches from heel to top of head .

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

Answer from: Quest

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
