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.
Answer:
Explanation:
You must find the solution of the system using the substitution method.
System:
Substitute x+2 for y:
Pass all the terms to one side:
Use the quadratic formula to solve:
Use y = x + 2 to find the value of y:
Answer:
632
Step-by-step explanation:
7 Days are in a week. 4,424 days total, 4,424 divided by 7 would equal 632
Answer:
The mistakes were on points C and D
Step-by-step explanation:
Point C was graphed on (5,8) when it's supposed to be plotted on (5,7). Point D was on (-3,-4) but was supposed to be on (-4,-3?
Answer:
<u>The zeros of this function would be: </u><u>x = 4 and x = 6</u>, assuming that option got caught off while you were taking a picture.
Step-by-step explanation:
When they're asking for the zeros of this type of function, where is forms this kind of U-shape or also known as a quadratic equation, <em>they're asking what the x-value is when y = 0</em>, or when the line of the function touches the x-axis. Notice that it happens when x = 4 and when x = 6.
In short, <em>it's asking what the x-value is of the points of the function when it intersects the x-axis</em>. Hopefully my explanation wasn't too confusing. Good luck on the rest of the quiz!
