Answer:
The correct options are;
D. Triangles ABC and A'B'C' are congruent
E. Angle ABC is congruent to angle A'B'C'
F. Segment BC is congruent to segment B'C'
H. Segment AQ is congruent to segment A'Q'
Step-by-step explanation:
The given information are;
The angle of rotation of triangle ABC = 60°
Therefore, given that a rotation of a geometric figure about a point on the coordinate plane is a form of rigid transformation, we have;
1) The length of the sides of the figure of the preimage and the image are congruent
Therefore;
BC ≅ B'C'
2) The angles formed by the sides of the preimage are congruent to the angles formed by the corresponding sides of the image
Therefore;
∠ABC ≅ ∠A'B'C'
3) The distances of the points on the figure of the preimage from the coordinates of the point of rotation are equal to the distances of the points on the figure of the image from the coordinates of the point of rotation
Therefore;
Segment AQ ≅ A'Q'.
First we need to find the square footage of her ceiling, since it's a square just multiply the side by the side: 44•44=1936. Now divide the square feet by how many feet each can can paint: 1936/242=8. Jenny would need exactly 8 cans of paint to paint her ceiling :)
15 is equal to 15, 24 is greater than 15 and so is 32, so c, d, and e are correct
Answer:
A.
Step-by-step explanation:
Proportionality concerns the ratio between two values, so C and D can be knocked off since they talk about difference. So that leaves us A and B. To find out if m and k are proportional, let's find the ratio between them (which means dividing them) for each set of speeds:
11.0/17.699 = 0.6215040398
26.0/41.834 = 0.6215040398
34.0/54.706 = 0.6215040398
We can see that all of the ratios return the same number, which means that the ratio of m to k is constant, so therefore the relationship is proportional, and the answer is A.
