The answer i got was c because the letter x goes into each of them because they each have a x in them. It would be B but 3 doesnt go into 28.
Answer:
1133.3 liters of water after leakage.
Step-by-step explanation:
x*.30=340
x=340/.30
x=1133.33
I believe the answer is C.
93.53 - 21.41 = 72.12
If you simplify C, its answer becomes equivalent to the answer of the original problem:
(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)
70 + 2 + 0.1 + 0.02
72.12
solution:
Z1 = 5(cos25˚+isin25˚)
Z2 = 2(cos80˚+isin80˚)
Z1.Z2 = 5(cos25˚+isin25˚). 2(cos80˚+isin80˚)
Z1.Z2 = 10{(cos25˚cos80˚ + isin25˚cos80˚+i^2sin25˚sin80˚) }
Z1.Z2 =10{(cos25˚cos80˚- sin25˚sin80˚+ i(cos25˚sin80˚+sin25˚cos80˚))}
(i^2 = -1)
Cos(A+B) = cosAcosB – sinAsinB
Sin(A+B) = sinAcosB + cosAsinB
Z1.Z2 = 10(cos(25˚+80˚) +isin(25˚+80˚)
Z1.Z2 = 10(cos105˚+ isin105˚)
