You have the correct answer. It is choice A. Nice work.
I prefer using full circles because sometimes the arcs could be too small in measure to not go where you want them to. If you're worried about things getting too cluttered (a legitimate concern), then I recommend drawing everything in pencil and only doing the circles as faint lines you can erase later. Once the construction is complete, you would go over the stuff you want to keep with a darker pencil, pen or marker. You can also use the circle as a way to trace over an arc if needed.
Choice B is false as a full circle can be constructed with a compass. Simply rotate the compass a full 360 degrees. Any arc is a fractional portion of a circle.
Choice C is false for similar reasoning as choice B, and what I mentioned in the paragraph above.
Choice D contradicts choice A, so we can rule it out. Arcs are easier to draw since it takes less time/energy to rotate only a portion of 360 degrees. Also, as mentioned earlier, having many full circles tend to clutter things up.
Answer:
I have to get the answer above hope it helps
Answer:
9/20
Step-by-step explanation:
First, turn the fractions into decimals then divide them and you get .45.
Find .45 in a fraction and it's 9/20. That's its simplest form.
Answer:
The correct option is;
B. Use a formula
Step-by-step explanation:
Given that Jim and Lillian have the dimensions of the wall they want to paint, therefore, in order to know how much paint they need to buy, they should proceed as follows;
1) Determine the quantity of paint required to paint a unit area of the wall, and record the quantity UA
2) Calculate the area, A, of the wall they want to paint, which is 15 ft. × 9 ft. = 135 ft.²
3) The amount of paint needed, AmP is therefore given by the following formula
AmP = A × AU = 135 × AU
