It would be false since none of them are equal to 1.
The scale of the drawing by using proportion is 3 : 5.
According to the given question.
Melissa drew a scale drawing of a city.
The width of the park in the drawing is 36 inches.
And the actual width of the park is 60 yards.
As we know that, a proportion is a fraction of a total amount, and the measures are related using a rule of three.
Therefore, the scale of the drawing by using proportion
= 36iches/ 60 yards
= 3/5
= 3 : 5
Hence, the scale of the drawing by using proportion is 3 : 5.

Answer: you are correct
Step-by-step explanation:
Answer:
The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5

The perimeter of the triangle is 40 units
<h3>Perimeter of a triangle</h3>
From the question, we are to determine the perimeter of the given triangle
From the given diagram, we can observe that the triangle is a right triangle
The vertical length of the triangle is 15 units
and the horizontal length of the triangle is 8 units
Thus,
We can find the hypotenuse by using the<em> Pythagorean theorem </em>
Let the hypotenuse be h
Then,
h² = 15² + 8²
h² = 225 + 64
h² = 289
h = √289
h = 17 units
Now, for the perimeter of the triangle
The perimeter of a triangle is the sum of all its three sides
Thus,
The perimeter. P, of the triangle is
P = 15 + 8 + 17
P = 40 units
Hence, the perimeter of the triangle is 40 units
