Answer:
11.9 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the side opposite the angle (BC) and the hypotenuse (14 cm).
Sin = Opposite/Hypotenuse
sin(58°) = BC/(14 cm)
BC = (14 cm)×sin(58°) . . . . . multiply by the denominator
BC ≈ 11.9 cm
1) You must add 4 to each side to complete the square.
2) You must add 16 to each side to complete the square.
3) You must add 27 to each side to complete the square.
Explanation:
1) x²-4x=0
To find the number that we add to both sides, we look at b, the cofficient of x. It is -4. We divide it by 2 and square it; -4/2 = -2; (-2)² = 4. This is the value that we add to both sides.
2) x²-8x=6
-8/2 = -4; (-4)²=16
We add 16 to each side to complete the square.
3) 3x²+18x=24
First we can factor a 3 out of the left side:
3(x²+6x) = 24
Our b value is now 6. 6/2 = 3; 3²=9. The 9 would, however, go in the parentheses, so it would be multiplied by 3, which makes 27; this means we would add 27 to both sides.
Answer:
0.224
Step-by-step explanation:
2/5% = 0.004
22% = 0.22
22% + 2/5% = 0.224

Answer:
Step-by-step explanation:
3% of 6600 = 198
1% or 6600 = 66
6600 + 198 + 198 + 66 + 66 + 66 + 66 + 66 + 66 = 7392
