I'm guessing this is a question about interest rates? If you have $20 that increases by 4% in one year, you need to multiply 20 by 1.04. This gets you $20.8.
If you are talking about compound interest, we will take this number and multiply it again by 1.04 for the second year. 20.8 x 1.04 = $21.632.
If it is instead simple interest, we will simply add another .8 dollars for each year, instead of getting 4% interest compounded every year onto the new value. This gets you $21.6.
Answer:
D
Step-by-step explanation:
If 1.6 km = 1 mile, you are looking for the comparison that will give you the answer under 120km. If the rate is 1.6km/mile, we want to know how many miles the car travels per hour if it travels 120 km in that first hour.
This will give you the answer.
A 10^7

Answer: 53.6
Explanation:
When given a side and its opposing angle and another angle, to find its opposing side you may use the sine rule.
sin(Angle)/opposing side = sin(Angle)/opposing side
Applying this formula will give us the following:
1) sin90/x = sin66/49
2) 1/x = 0.01864
3) 1/0.01864 = x
4) x ≈ 53.6
Hope this helps, brainliest would be appreciated :)
