Anyone know what the answer is???(sorry if it’s unclear)

Sergio [31]

The laws of exponents I will be using are:

$(x^y)^z = x^{yz}$ , and $x^y \cdot x^z = x^{y+z}$ .

For the first part, $(15^3)^3 \cdot 15^{-6} = 15^9 \cdot 15^{-6} = 15^3$ .

For the second part, $15 \cdot (15^3)^2 \cdot (15^{-5})^2 = 15 \cdot (15^6) \cdot (15^{-10}) = 15^{1+6-10} = 15^{-3} = \frac{1}{15^3}$ .

Explain how to find the number of grams of fat in 2.5 cups of corn if there are 7.87 grams of fat in 1 cup of corn

Alina [70]

7.87g/2.5cups= 3.148 (3.15)

3.15+3.15=6.30

3.15/2=1.575 (1.58)

6.30+1.58=7.88

So approximately 3.15 grams of fat equals 2.5 cups of corn

Kevin says that lines p and m will eventually intersect. Lines A and B intersect. Plane A contains lines p, m, and n. Line n is

ANTONII [103]

Answer:

No, because they are parallel.

Step-by-step explanation:

The lines $p$ and $m$ will not intersect, so Kevin is not correct.

It is given that planes A and B intersects. The plane A contains the line p, m and n on its plane. The lines p and m are parallel to each other. They are identical and move in the same direction.

Since the line p and m are parallel, they will not meet each other at any point because parallel lines does not intersect or meet at a point, they run parallelly along each other.

So, line p and m will not intersect.

Thus the answer is " No, because they are parallel."
