Answer:

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 .

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%

Answer:

The approximate height of the statue is:

x = 144

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

lubasha [3.4K]

Your answer is D.


The jeans are 40% off (because you add 20% more).

And the original cost of the jeans is $30.


You could have done:

30 · 0.40 = 12  (Find 40% of $30, then subtract 30 by 40% of 30 to get the new sale price]

30 - 12 = 18


1 - 0.40 = 0.60  (You subtract 1 by 0.40 to get 0.60, which is the % of the original price that you have to pay)

30 · 0.60 = 18

A line of roses forms the diagonal of a rectangular flower garden. Th e line of roses is 18.4 m long, and one side of the garden
professor190 [17]
Given that the garden is rectangular and a line of roses form the diagonal 18.4 m long, we required to calculate the length of the perpendicular side.
Here we shall use the Pythagorean theorem.
c²=a²+b²
where c is the hypotenuse, a and b are the legs.
from the information given:
c=18.4 m
a=13 m
plugging this into our expression we get:
18.4²=13²+b²
next we solve for the value of b
b²=18.4²-13²
b²=338.56-169
b²=169.56
b=√169.56
b=13.0215
hence the length to the nearest tenth of a meter will be approximately 13.0 m
