Some one help me please

Answer 1

Answer:

For this case we have that by power properties it is fulfilled:

$(a ^ n) ^ m = a ^ {n * m}$

Now, we can rewrite the expression as:

$\frac {64g ^ 9 * h ^ 6 * k ^ {12}} {8g ^ 3 * h ^ 2} -h ^ {25} k ^ {15} =$

We also have by definition of properties of powers that:

$\frac {a ^ m} {a ^ n} = a ^ {m-n}$

So:

$8g ^ {9-3} * h ^ {6-2} * k ^ {12} -h ^ {25} k ^ {15} =\n8g ^ 6 * h ^ 4 * k^(12) -h^(25) * k^(15)$

Answer:

Option D

you have 150 songs on your IPod. The Probablity of randomly choosing a country song is 20%. How many of the songs on your IPod are not country songs

Answers

In this question, we're trying to find the probability of the songs that are not country songs.

We know that you have a total of 150 songs.

There is a 20% probability of randomly choosing a country song, so let's calculate how many country songs are there.

150 · 0.20 = 30

There are 30 country songs in your iPod.

Now, to see how many songs you have that are not country songs, subtract 30 from 150

150 - 30 = 120

This means that you have 120 songs that are not country songs

Answer:

120 songs

Answer:

30Songs are not country songs

Step-by-step explanation:

X/150=20/100

100X=3000

100X/100=3000/100

X=30

Which leader of the Hebrew people gave them the Ten Commandments? A. Isaac B. Moses C. Miriam D. Noah

God gave the Hebrew people the "Ten Commandments".
It had to go through Moses, because the people were too
scared to hear it directly from God, and they begged Moses
to go get it and bring it to them.

Now, if you want to say "So then it was really Moses", then

What si the answer to this? I'm bad at graphs sorry :). Btw it's number 22

Answers

a) To find amount collected in each category - you must understand that the numbers inside the circle represent an angle (in units of degrees). Since we know a circle is composed of 360 degrees, we know each other portions as a ratio of that full circle

for simplicity sake, i will use "d" to represent "degrees"

Shirts = (140d)/(360d)*($7200) = $2800
Pants = (80d)/(360d)*($7200) = $1600
Other = (75d)/(360d)*($7200) = $1500
Shoes = (360d - 140d - 80d - 75d)/(360d)*($7200) = $1300
Total = $7200 [OK]

b) Knowing long sleeve shirts are to be 1/4 of the shirts sales, find the angle which represents in on the pie graph:

angle (long sleeve shirts) = 1/4*(140d) = 35d

c) Assuming ratios to maintain over the next $900 of sales

Pant sales (in the next $900 of total sales) = ($900)*(80d/360) = $200

hope that helps

If It is in fact (b), then it's 90 degrees

You buy a bookshelf. The label on the box says the bookshelf is 51 inches tall. How tall is it in feet?

Answers

A feet is 12 inches.

$51/12=4.25$

The bookshelf is 4 feet, 3 inches.

i think you take 51 and divide by 12 bc there are 12 inches in a foot. if that's right then the answer should be 4.25 feet.
