Answer:
<h2>$38.4</h2>
Step-by-step explanation:
Step one:
we are told that the price online is $39.99
and that the discount is 10%
and also tax is 6%
Step two:
discount
let us solve for the deduction first
=10/100*39.99
=$3.99
Tax
=6/100*39.99
=$2.4
The final cost= cost online-10% discount+6% tax
Final cost= 39.99-3.99+2.4
Final cost = $38.4
Answer is 5.4 units
Step by step.
I used Pythagorean theorem to find the diagonal (hypotenuse) of the triangle.
We know the height (y) is 5 and the other leg (x) is 2.
a^2 + b^2 = c^2 is the formula.
Substitute the two legs in for a and b.
5^2 + 2^2 = c^2
29 = c^2
Now take the square root of both sides
5.385 = c
Round to nearest tenth = 5.4 units
2 cubed. Cubed also means multiply so enjoying by itself times. So, 2 * 2 = 4 * 2 = 8.
2 cubed = 8
