Answer:
16 cm^2 and 49 cm^2
Step-by-step explanation:
The ratio of areas is the square of the ratio of linear dimensions, so is ...
(4/7)^2 = 16/49
The sum of these "ratio units" is 16 +49 = 65. The sum of triangle areas is 65 cm^2, so each "ratio unit" must stand for 1 cm^2 of area. That is, the triangles must have areas of ...
Answer:
-24
Step-by-step explanation:
I´m guessing by the big x sign you want me to multiply so the first step in the equation is to multiply because of PEMDAS so(6*2)+(8*-3)-3*2-6,
so 6*2=12,8*-3=-24,-3*2=-6
12+-24-6-6,
12-24=-12,-6+-6=-12
-12+-12=-24
Answer:
33
Step-by-step explanation:
Add all the numbers
Divide by 9
You might want to stick to at most five questions at once, makes it easier for the rest of us. :)
17. T has a vertical line of symmetry (along the center line).
18. Z looks the same if you turn it halfway around.
19. The passes total to 150°, which is a little less than 180°, so I estimate it would be in front of Kai.
20. Left is the -x direction. Up is the +y direction. this is (x-6, y+4)
21. Every dilation has a center (where it's dilated from) and a scale factor (how much it's dilated).
22. It must be A, because it's the only one where the number of moves adds up to 16.
23. It can be determined to be B just by tracking where point C would end up through the transformation.
24. A 180° rotation flips the signs on both components to give you (-1, 6).
25. Right is the +x direction. Down is the -y direction. (x+3, y-5)
26. This is a reflection.
Need clarification on anything?
Pretty sure law. judicial means of, by, or appropriate to a court or judge.
