In one lemonade bottle, there would be 2000mL. (1L = 1000mL)
Answer:
You just need to find the length of LM and NM and then find the area of semi-circles using the formula πr²÷2
By using The half-angle formula
cos X/2 = ±√[(1 + cos X)/ 2]
But we have cos x=2/3
= ±√[(1 + 2/3)/ 2]
= ±√[(5/3 )/ 2]
= ±√[(5/5]
=±√1
Therefore answer is ±1
cos A/2 = ±√[(1 + cos A )/ 2]
Answer:
$8.40
Step-by-step explanation:
"20% off" translates into multiplication of the regular price by (1 - 0.20), or 0.80:
The price after discount is 0.80($10.50) = $8.40
