Answer:
1201.2 in (100.1ft)
Step-by-step explanation:
A scale model represents a ratio. All sides must be shrunk or increased based on a constant value. In this case the ratio of the model is 1/13 the size of the original giving us a 1:13 ratio. So each side of your scale model must be multiplied by 13 to find the real value of the side.
First convert all units to inches then divide the width of the real windmill by the width of the scale model (both in inches) you will see the answer is 13. Multiply the inch values of all sides of your model by 13 and this gives you the proportional value of each side of the real windmill in relation to the scale model.
a₅ = 10
a₁₀ = 20
a₁₅ = x
-------------------------------------------------------------------------------------------------------------------
Note that from a₅ to a₁₀, there is a addition of 10. This means that for every x(₅) jump, you add 10 to the whole number.
-------------------------------------------------------------------------------------------------------------------
So in this case:
a₁₀ = 20
a₁₅ = x
a₁₀ (+₅) = 20 (+10)
a₁₅ = 20 + 10
a₁₅ = 30
Note that: a₁₅ = x = 30
-------------------------------------------------------------------------------------------------------------------
x = 30, or (A) is your answer

The unit rate is 5 1/3 grams per serving.
To find the unit rate, we can use the rule of three. If 4 grams are equivalent to 3/4 serving, how much grams would be 1 serving? Therefore, the unit rate is 5 1/3 grams per servin
Answer:
y = -5
x = 2
Step-by-step explanation:
The computation is show below:
Given that
-6x - 6y = 18
6x - 3y = 27
Now if we solved both equation so
-9y = 45
y = -5
And, x is
-6x - 6(-5) = 18
-6x + 30 = 18
-6x = 18 - 30
-6x = -12
x = 2
Simplifying
6 + -6x = 5x + -9x + -2
Reorder the terms:
6 + -6x = -2 + 5x + -9x
Combine like terms: 5x + -9x = -4x
6 + -6x = -2 + -4x
Solving
6 + -6x = -2 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
6 + -6x + 4x = -2 + -4x + 4x
Combine like terms: -6x + 4x = -2x
6 + -2x = -2 + -4x + 4x
Combine like terms: -4x + 4x = 0
6 + -2x = -2 + 0
6 + -2x = -2
Add '-6' to each side of the equation.
6 + -6 + -2x = -2 + -6
Combine like terms: 6 + -6 = 0
0 + -2x = -2 + -6
-2x = -2 + -6
Combine like terms: -2 + -6 = -8
-2x = -8
Divide each side by '-2'.
x = 4
Simplifying
x = 4
I hope this helps!
