Hello!
Use the equation F = m · a to solve where:
F = total force (N)
m = mass (kg)
a = acceleration (m/s²)
We are given the force and mass, so we can plug these values into the equation to solve.
However, mass is used in kilograms, so we must convert from grams to kilograms:
1 kg = 1000 grams
Convert using dimensional analysis or proportions:
Plug in the force and mass to solve:
6.5 = 0.5(a)
Divide both sides by 0.5 (Multiply by 2)
a = 13 m/s²
c^2 = a^2 + b^2
looking for C the hypotenuse
a = 35
b = 12
These are the sides
c^2 = 35^2 + 12^2
c^2 = 1225 + 144
c^2 = 1369
Then take the square root of both sides to get C
C = 37
So according to the problem, the tax should be calculated using the bill.
So 5.5% equals to 0.055.
Then multiply 0.055 and 74.98.
Thus resulting in 4.1239 and when rounded, the answer should be 4.12, C
Is that a test or just regular homework? If it is a test I can't help you.
Answer:
Step-by-step explanation:
sin = opposite/hypotenuse
In this case
AB = hypotenuse
BC = opposite
sinA = BC/AB=12/13
so the correct answer is A
