X=5 because 5•4=20, 20-7= 13
2•5=10, 10+3=13
Answer:452.16m^2
Step-by-step explanation:
C=2πr
75.36m=2×3.14×r
75.36m=6.28r
r=12m
Area=πr^2
A=3.14×12m×12m
A=452.16m^2
Answer:
180
Step-by-step explanation:
Do 6 Times 30
Answer: The correct option is figure (1).
Explanation:
Reason for correct option:
The figure (1) shows the reflection across the side XY followed by reflection across the side YT.
When we reflect the triangle XYZ across the side XY we get the triangle XYT as shown in below figure.
After that we reflect the triangle XYT across the side YT and we get the triangle PYT.
Therefore, only figure 1 shows the triangle pairs can be mapped to each other using two reflections.
Reason for incorrect options:
The figure (2) shows the rotation of 180 degree along the point y.
The figure (3) shows the reflection across the side XY followed by the translation.
The figure (4) shows the reflection, followed by rotation , followed by translation.
Ans 7, 9, 11
Step-by-step explanation:
Think of it as an equation. You have 3 integers x, y, and z.
x + 2y = z + 14.
Plug in consecutive odd integers, picking your next set of trial and error integers based on how far off the equation is.
In this case, 7 + (2 * 9) = 11 + 14
In this example, it took me three attempts to get the correct answer.
