Answer:
60
Step-by-step explanation:
area of triangle ACF is (1/2) (AC) (CF) = 180
area of triangle BCE = (1/2) (BC) (CE)
BC = AC/2
CE=(2/3) CF
so (1/2) (BC) (CE) = (1/2) (AC/2) (2/3)CF = (1/2)(2/3)(180) = 60 sq cm
Answer:
She had five crackers.
Step-by-step explanation:
Originally, she had only 1 cracker. Since she bought 4 more from the store, it adds to the current amount she had. So 1+4= 5.
Answer:
B.)21.4
Explanation
A(-4, 3), B(0,2), C(2,4) and D(0,-3)
AB = √(1²+4²) = √17 =4.12
BC = √(2²+2²) = √8 = 2.83
CD = √(2²+7²) = √53 = 7.28
AD = √(4²+6²) = √52 =7.21
Perimeter = 4.12+2.83+7.28+7.21 = 21.44
To the nearest tenth the answer is 21.4.
6th becuase 12-11 would be 1 and up 5 eould be 6
