Answer:
$3
Step-by-step explanation:
Original price - Discounted price
= $15 - ($15 × 80%)
= $15 - ($15 × 80/100)
= $15 - ($1200/100)
= $15 - $12
= <u>$</u><u>3</u>
So, the sale price is $3

Answer:
C
Step-by-step explanation:
We know that the volume of a cylinder is given by the formula:
And we want to find the expression that represents the volume when the radius is (x+8) and the height is (2x+3).
So, let's substitute (x+8) for r and (2x+3) for h. This yields:
Let's expand.
Expand the square term first. We can use the perfect square trinomial pattern, which is:
Here, our a is x and b is 8. So:
Simplify:
Expand further. This time, we will use the distribute property. So:
Multiply:
Combine like terms:
Add:
Distribute the π:
So, our answer is C.
And we're done!
There is a formula for this:
Total Time = (worker1 * worker2) / (worker1 + worker2)
(3 * 8) / (3 + 8)
24 / 11 =
2.1818181818 hours
Assuming you already have your slope. Let’s assume you have a slope of 3/4. (m=3/4)
Slope intercept form is y=mx+b
y and x being a point
m is your slope
and b is your y-intercept
So for example, you have a y-intercept of 3, your equation would be y=3/4x+3
Standard form is Ax+By=C
