Step-by-step explanation:

X^2y12/ xy^5

= x^2–1 • y^12–5

= xy^7

Answer:

[tex]xy^7=x^ay^b[/tex]

Step-by-step explanation:

[tex]\frac{x^2(y^3)^4}{xy^5} = x^a * y^b[/tex] = [tex]\frac{x^2(y^12)}{xy^5} = x^a * y^b[/tex]

[tex]\frac{x^2(y^12)}{xy^5} = x^a * y^b[/tex] = [tex]\frac{x^2(y^7)}{x} = x^a y^b[/tex]

[tex]\frac{x^2(y^7)}{x} = x^a y^b[/tex] = [tex]x^1y^7 = x^ay^b[/tex]

[tex]x^1y^7 = x^ay^b[/tex] = [tex]xy^7=x^ay^b[/tex]

Answer:

[tex]\huge\boxed{\boxed{5w+30}}[/tex]

Step-by-step explanation:

Hello.

The Distributive property states that

a(b+c)=ab+ac

Let's use this property to simplify:

5(w+6)

5w+30 (5 times w and 5 times 6)

Answer:

5x5 is 25 and 5+5+5+5+5 is also 25 please give brainliest

Step-by-step explanation:

Answer:

5*5=5+5+5+5+5

Step-by-step explanation:

Both are equivalent because both include adding 5 fives together, if you were to space out the 5*5 it would be equivalent. Also, if you add 5+5+5+5+5 it would equal 25 and 5*5=25. That is why they are equivalent. Hope this helps, let me know if correct, and have a great day!!

Answer: the supplementary angle is 30.2

Step-by-step explanation:

Answer:

1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.

2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)

3. I don't know I am way to tired sorry

Step-by-step explanation:

1. When manure or fertilizers enter water, the nutrients they release stimulate microorganism growth. These microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in water, fish and other animals living in water suffocate.

2. Eutrophication is the process by which water bodies are enriched with minerals and nutrients.

Sorry I don't know the answer to question 3

Answer:

She has wrapped 15 packages.

Step-by-step explanation:

Heres how I did it. I used my fingers for this, it's a little odd I know but it works. I put up one finger for each half. So each finger represents one half. I needed to get to 2 1/2 so I put up two finger and I said "that's one " because a half plus a half is a whole or just one. Then I put up one more finger and I said " That's one and a half". I then put up two more and then I had 2 1/5. What I did then was count how many fingers I had up. I had 5 fingers up. So then I multiplied 3 x 5 and that gave me 15. Hope I could help!

Answer:

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

Answer:

$22

Step-by-step explanation:

She gives 2 dollars per week for 3 weeks.

If she gives back 2 dollars each 3 weeks, we would solve for 2 x 3

2 x 3 = 6

28 - 6 = 22

$22 dollars represents her amount of debt.

Answer:

-6

Step-by-step explanation:

$28

$2/week

$28 - (2x3) = $22

$22 - $28 = -$6

Answer: C: 4

Step-by-step explanation:

The domain of the function f(x) is: -6 < x ≤ 4, and the value that is in the domain of the function f(x) is 4

The function is given as:

f(x) = 2x + 5,   -6 < x ≤ 0

f(x) = 2x + 3,   0 < x ≤ 4

The above means that the domain of the function f(x) is:

-6 < x ≤ 0 and 0 < x ≤ 4

When combined, we have:

-6 < x ≤ 4

This means that x is greater than -6 but does not exceed 4

Hence, the value that is in the domain of the function f(x) is 4

Answer:

Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.

Find and compare the means to the nearest tenth.

7th-grade mean:

✔ 16

5th-grade mean:

✔ 13.4

What is the relationship between the means?

✔ The 7th-grade mean is about 2.5  points higher.

Step-by-step explanation:

Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

The mean is the average of the data set, that is the sum of each data value divided by the number of data points.

Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.

Mean for 7th Grade Students:

Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21

Mean = 335/21

Mean = 15.95 = 16

Mean for 5th Grade Students:

Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19

Mean = 281/21

Mean = 13.38 = 13.4

The difference between their means = 16 - 13.4 = 2.6.

Hence, Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.
