Answer:
162
Step-by-step explanation:
18 + 63 + 81
Area of the parallelogram is A=hb and the area of the triangle is A=hb/2 so
A=9(11)+7(11)/2
A=137.5 cm^2
20 each girl
40 divided by 2 girls is 20
a² = 144
b² = 25
c² = 169
c = 13
• a² = 12×12
= 144
• b² = 5×5
= 25
• a² + b² = c²
= 144 + 25 = 169
• c = _/169
= 13
we can use formula
now, we can find a and b
Initially , price is 500
so,
At
now, we can plug back
we can use it and find b
now, we can solve for b
and we get
annual depreciation rate is 27.144%.......Answer
{5,7,8}
A-B = {2,4,6} => A={2,4,6}
B - A = {0,1,3} => B= {0,1,3}
A∪B = {0,1,2,3,4,5,6,7,8}
=> A = {2,4,5,6,7,8}
B= {0,1,3,5,7,8}
=> A∩B = {5,7,8}
