Answer:
The tax is $0.12
Step-by-step explanation:
If you can imagine that price of $3 to be 100% of the price, you can simply add 4.4 onto this to find the percentage you need to find of the price:
100 + 4.4 = 104.4
So now you can use the percentage formula:
Amount x
Simply plug all the values into this:
3 x
3 x 1.04 = 3.12
Now you have the total price and you can simply minus the item cost without tax:
3.12 - 3 = 0.12
<h3>So the tax is $0.12!</h3><h3 /><h2>Hope this helps!</h2>Answer:

sinC=0.2800
C=16.26°
The direction of the resultant
vector is measured from0°east
to the resultant, this angle isθ−90°,
90°is the total angle in
the first quadrant.
∴θ−90°=C+ϕ
ϕ=50°{Alternate angles are equal}
∴The direction of the car’s
resultant vector is50°+16.26°=66.26°south of east
