Answer:

A and C

Step-by-step explanation:

<u>Rewriting for the sake of clarity:</u>

<em>Select all radical expressions that are equivalent to</em> $3^{\frac{4}{7}}$

$a)(\sqrt[7]{3^{4}})\\b)\sqrt[4]{21}\\c)\sqrt[7]{81}\\d)\sqrt[4]{3^{7}}\\e)\sqrt[7]{12}\\f)\sqrt[4]{3^{7}}$

1) According to the Exponents Law, when we have a fraction as an exponent the numerator of it will be the radicand's exponent and the denominator will be the index of it.

$3^{\frac{4}{7}}=(\sqrt[7]{3^{4}})$

2) We can raise the 3 to the 4th power. And rewrite the radicand as the result of that:

$3^{\frac{4}{7}}=\sqrt[7]{3^{4}}=\sqrt[4]{21}$

Which set of points includes all of the solutions for y = 5/2x + 3/2?

Firdavs [7]

Answer:

Choice A: $(x,\frac{5}{2}x+ \frac{3}{2} )$ . for all real numbers.

Step-by-step explanation:

We are looking for points on the x-y plane which satisfy the equation y = 5/2x + 3/2, and these point are all those that lie on the graph of the equation, which are points $(x,y) = (x,\frac{5}{2}x+ \frac{3}{2} )$ .

Looking at the other choices we see that choice B gives only 3 points, and regardless of whether they lie on the graph of y or not, this choice cannot be correct because 3 points are not all solutions.

The same goes for choice D.

And choice C is just the whole of x-y plane, therefore this cannot be the answer because not every point on the x-y plane is a solution to y = 5/2x + 3/2

To make 6 apples pie, you need 2 pounds of apples. How many pounds of apples do you need to make 10 apple pies?

Bezzdna [24]

For every 6 apple pie, you need 2 pounds of apples.
So, how many pounds of apples do you need for 10 apple pies?
Well, first to figure out this question we first need to make a conversion factor.
I see in the fraction 6/3 we can simplify that to 2/1. Now we got our conversion factor.
We need to invert the fraction in order for the pie unit to cancel out.
1/2 * 10 = 5

You will need 5 pounds of apples to make 10 apple pies.
