Hope this helps :)
Answer:
The significant figure of the result is 138.8
Step-by-step explanation:
24.78*(37.3 - 31.72)
Solving the bracket first:
37.3 - 31.72 = 5.58
A zero is added to 37.3 before the substraction, so;
37.3 - 31.72 = 37.30 - 31.72 = 5.58
Following the rule of significant figure; we have the answer of the substraction as 5.6 since the least number of significant is one decimal place.
The new expression will be:
24.78 * 5.6 = 138.768
Therefore, the result of our expression 138.8 by following the rule of significant figure
If we know that 6 things cost 2.99 and we want to know unit price we just have to divide 2.99 by 6.
So 2.99:6=0.49$ - its the result.
Now we can say that his sister is not correct, because price is different that 2$/unit.
Answer:
point "i" has coordinates (-x, y)
Step-by-step explanation:
Any point on the horizontal line containing point A will have the same y-coordinate. It appears that point "i" in the diagram is a point on the circle and on the horizontal line, so is the point you're looking for. Because the circle is centered at the origin, point "i" will have an x-coordinate that is the opposite of that of point A.
Point "i" is such a point. It has coordinates (-x, y).
