Since the midpoint lies on the axis, both ends are therefore equidistant from the axis and are mirrors of each other so..
Q = (4,9)
Answer:
C) Maria bought a magazine for $8 and 2 notebooks. She spent a total of $15. What was the cost of each notebook?
Step-by-step explanation:
The equation has twice an unknown value added to 8 with the result being 15.
<em>Here are how the answer choices compare to the equation:</em>
A) only one magazine of unknown cost is involved, not two. There is not enough information to answer this question with any equation.
B) three unknowns are involved and the question asks for the difference of their sum and 15. There is not enough information to answer this question with any equation.
C) if x represents the cost of the notebook, the equation is appropropriate to finding its cost, as asked by the question. This is the best choice.
D) only one unknown. The question makes no sense, as she bought items worth more than the amount paid.
Answer:
120
Step-by-step explanation:
If you multiply these numbers you will eventually find that they all have a common multiple of 120. 120 is also the least common multiple so therefore, the lcm is 120
1. Let's review the information given to us to answer the question correctly:
Height of the Willis Tower in Chicago = 1,454 feet
Scale of the model = 2 inches : 45 feet height
2. How tall is the height?
For answering that question, we will use the following expression:
Height of the model = Height of the Willis Tower in Chicago/Scale in feet * Scale in inches
Replacing with the real values, we have:
Height of the model = 1,454/45 *2
Height of the model = 32.31 * 2 = 64.62 inches
64.62 inches/12 = 5.39 feet
The model is 64.62 inches of height or 5.39 feet
