To answer this question, we have that the scale factor is 1 / 12, and it says that the model is 1/12 the size of the actual length.
Then, we have that the actual length is 21 feet. The size of the model is:
We need to remember that units are not mentioned in a scale factor.
Now, we need to transform the size of feet into inches. We know that in one foot we have 12 inches, then, we can take this into account to have the missing dimension item (length in inches):
Therefore, the missing dimension is 21 inches (the model is 21 inches in length.)
He first step to solving this question is distributing the three and the four once you have your new equation of 6x+3-8x-20 you can easily add or subtract once you do this you should have -2x-17 which is the answer.
dont know wish i could help you :( sorry i hate when i can't answer a question it makes me feel bad
The answer will be 190.76 square inches. Hope it help!
If the diameter of the circle is 18 feet, the circumference of the circle is 56.55 feet.
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.
The diameter of a circle is 18 feet.
D = 18 feet
Now, the radius of the circle is half the diameter of the circle.
Therefore,
Diameter = 2 × Radius
Radius = Diameter / 2
D = 2r
r = D / 2
r = 18 feet / 2
r = 9 feet
Now, the circumference of a circle is given as:
Circumference = π × diameter
Circumference = π × 2r
Circumference = 2πr
Circumference = 2 × π × 9 feet
Circumference = 2 × 3.14159 × 9
Circumference = 56.55 feet
