Answer:
(2,6)
Step-by-step explanation:
Since its reflecting on the y axis, the rule for that is (-x,y) for x the sign changes, and y stays the same. The coordinates for Q are (-2,6) and when you use the rule itll come out to (2,6)
Answer:
x = 5, y = 3
Step-by-step explanation:
<u>Elimination method: (I will be eliminating 4y) </u>
3x + 4y = 27 --- Equation 1
x + 4y = 17 --- Equation 2
Equation 1-2: 3x + 4y - x - 4y = 27 - 17
2x = 10
x = 10 ÷ 2
x = 5
Substitute x = 5 into Equation 2:
x + 4y = 17
4y + 5 = 17
4y = 17 - 5
= 12
y = 12 ÷ 4
y = 3
Answer:
20%
Step-by-step explanation:
% of error is given by the following formula:
% Error = 
Now, Jessie estimated the weight of his cat to be 12 pounds i.e. Approximate value is 12 pounds.
Again, The actual weight of the cat is 15 pounds i.e. the exact value is 15 pounds.
Therefore, the % error = 
% (Answer)
Answer:
60*pi square inches
Step-by-step explanation:
We have a cone that originally has 15 * pi square inches of area, now it tells us that it is enlarged by a scale factor of four, to make a cone with the same shape.
In other words, if it was a cone with a circular base, this new cone will also be a circular base, the same happens if it is a square base.
Therefore, taking this into account, the new cone area is
15 * 4 * pi = 60 * pi
That is, the area of the new cone would be 60*pi square inches.
