Decide whether the two figures are similar. . Triangle A: (1,4), (3, 5), (4,2) Triangle B: (0, 5), (4,7), (6, 1)
puteri [66]
Answer:
Step-by-step explanation:
triangle A sides
√((5 - 4)² + (3 - 1)²) = √5
√((5 - 2)² + (3 - 4)²) = √10
√((4 - 1)² + (2 - 4)²) = √13
triangle B sides
√((7 - 5)² + (4 - 0)²) = √20 = 2√5
√((7 - 1)² + (4 - 6)²) = √40 = 2√10
√((6 - 0)² + (1 - 5)²) = √52 = 2√13
As each leg of B is twice a leg of A, they are similar
Let S=score on the second exam, then
(67+S+(S+7))/3=84
cross multiply
2S+74=252
2S=178
S=89
So second exam: 89
third exam=89+7=96
Check: (67+89+96)/3=84 ok.
Answer:
B and D
Step-by-step explanation:
they both can go into those
So 7=7/1
to put a 9 in the bottom and make the fraction stay the same, multiply it by 1
or 9/9 since 9/9=1 so
7/1 times 9/9=(7 times 9)/(1 times 9)=63/9
answe ris 63/9
