Answer:

$40 was the original price.

Step-by-step explanation:

10% = 0.1

36 / (1 - 0.1) = 40

Answer:

$40

Step-by-step explanation:

Original price - discount = sales price

discount = original price * percent off

Substituting this in

Original price - original price * percent off = sales price

Factor out the original price

Original price (1-percent off) = sales price

We know the sales price = 36

and we know the percent off = 10 percent = .1

Substituting in

Original price (1-.1) = 36

Original price (.9) = 36

Divide both sides by .9

Original price *.9/.9 = 36/.9

Original price = 40

Let's assume that you are to graph the inequality.
1. Graph -3x + 4y = 12. Note that the x-intercept is (-4,0) and the y-intercept is (0,3). Use a dashed line, not a solid line, due to the ">" sign.
2. Choose a test point (e. g., (0,1) ) and subst. these coordinates into -3x + 4y = 12. Is the equation then true or false? If true, shade the area (on one side of -3x + 4y = 12 or the other) in which the test point (0,1) lies. If false, shade the other side of -3x + 4y = 12.

What is the integral ln x^1/3 dx.

Maksim231197 [3]

Hello,

$\int\limits{ln(x^\frac{1}{3}) } \, dx =\frac{1}{3}*\int\limits{ln(x) } \, dx \\\\
=\frac{1}{3}*(x*ln(x)-x)+C=\frac{x}{3}*(ln(x)-1)+C


$
Th $\int\limits{ln(x) } \, dx=x*ln(x)- \int\limits{x* \frac{1}{x} \, dx \\\\
=x*ln(x) -x+C$

The last integration is made by "parties(in french)"

$\int\limits{ln(x)} \, dx =x*ln(x)- \int\limits{x* \frac{1}{x} } \, dx \\\\
=x*ln(x)-x+C

Amy has 1/2 hour to do 3 chores. She plans to spend the same fraction of an hour on each chore. She wants to use the number line

Natali5045456 [20]

Point A would be zero; Point B, the end of the 1/2-hour time interval, would be 1/2 (representing 1/2 hour). Then Amy needs to subdivide the interval A to B into three equal time intervals and to determine the length of each of these subintervals.

I would begin with 1/2 and divide that by 3:

1
--
2
====
3
--
1

Inverting the fraction in the denom. and multiplying, we get

1 1 1
-- * ---- = -----
2 3 6

So Amy will spend 1/6 th of an hour, or 10 minutes, on each chore.

Note that 3 times 1/6 comes out to 1/2 (hour), which is were we started.
