Answer:
a reflection across line bc
Step-by-step explanation:
maybe, I think so
Answer:
A
Step-by-step explanation:
The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!
Answer:
Third bar graph.
Step-by-step explanation:
Given : 5x + 7.5 = 15.
To find : Which bar diagram represents the equation.
Solution : We have given 5x + 7.5 = 15
In the equation we can see sum of 5x and 7.5 is 15 .
By the bar graph combination box of 5x and box of 7.5 is equal to the box of 15.
Then Third bar graph represent the equation .
Two pink boxes of 5x and 7.5 and one blue box of 15.
Therefore, Third bar graph.
To draw a locus point you have to draw<span> the half way line through the two </span>points. You can do this by drawing<span> the line bisector through AB points. Just open your compass to ¾ of the distance AB and then </span>draw<span> two arcs from both sides of your line. Once this is done </span>draw the line passing through the two intersection points<span>.
Hope this helps :)</span>
Area of sector = (1/2) * r^2 * α where α = the angle in radians
= 1/2 * 12^2 * π/3
= 72 π / 3 = 24 π Answer
