Answer: -1.17
Step-by-step explanation:
I guessed and got it right
1)

3)

notice the rate "r"... now, is in decimal format, as you saw on 1) is just r/100 so 1.6% was really 1.6/100 or 0.016 anyhow
to get the percentage form, just multiply it by 100
Easy. If 1 In. = 2.54 Cm. then the equation would be 47 * 2.54 = 119.38.
Answer:
Step-by-step explanation:
12). By applying Pythagoras theorem in the given right triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
x² = 7² + 7²
x² = 2(7)²
x = 
x = 
13). By sine rule,
sin(60)° = 

y = 
y = 18
By cosine rule,
cos(60)° = 

x = 
x = 
14). By applying Pythagoras theorem in the given right triangle,
12² = x² + x²
144 = 2x²
72 = x²
x = √72
x = 6√2
