9 is D and 10 is B. Take the slope of the point you are trying to move, and go to the counter clockwise axis. Do the slope but in its reciprocal form. If you sketch out the answers I’ve given, it should help visualize the method.

Profit or loss question..please solve this

Yuki888 [10]

Answer:

I would say he makes 10.5%

Step-by-step explanation:

Let the price at which the shopkeeper bought the article be 100.

Since he has to make a profit of 30%, he would mark the price as 130.

Now, he allows a discount of 15% i.e. 15% of 130 = 19.5

The actual discounted price= 130–19.5= 110.5

He gets 10.5 on 100. The profit percent he makes is 10.5%

Which expression is equivalent to \root(3)(x^(5)y)

san4es73 [151]

Answer:

$\sqrt[3]{x^{5}y} = x^{\frac{5}{3}}y^\frac{1}{3}$

Step-by-step explanation:

Given

$\sqrt[3]{x^{5}y}$

Required

The equivalent expression

We have:

$\sqrt[3]{x^{5}y}$

Rewrite as an exponent

$\sqrt[3]{x^{5}y} = (x^{5}y)^\frac{1}{3}$

Open bracket

$\sqrt[3]{x^{5}y} = x^{5*\frac{1}{3}}y^\frac{1}{3}$

$\sqrt[3]{x^{5}y} = x^{\frac{5}{3}}y^\frac{1}{3}$
