Answer:
the individual price of a popcorn is $8.
Step-by-step explanation:
p+2d=14 is the price with deal
p+2d=14+4 if there was no deal
plug 5 into the equation as d
2(5)+p=18
solve for p.
p=8
Hello from MrBillDoesMath!
Answer:
27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
Discussion:
Let f(t) - 9 sqrt(t) sin(t), then
y' = f(x^3) * d(x^3)/dx - f(sqrt(x)) * d(x^1/2)/dx
= (9 sqrt(x^3)sin(x^3)) * 3x^2 - (9 sqrt(x^1/2)sin(x^1/2)) * (1/2) x^-(1/2)
= 27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
Hope I didn't make a "bozo" error differentiating things!
Thank you,
MrB

Answer:
<h2>$867.37</h2>
Step-by-step explanation:
<h3>tax rate = 7.75%</h3><h3>sale prize = $804.99</h3><h3>tax = (804.99 × 7.75) / 100</h3><h3> = 62.38</h3><h3>amount with tax = $804.99 + $62.38</h3><h2> = $867.37</h2>

Answer:
If a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
