A chemical compound requires 8 ounces of chemical A and 12 ounces of chemical B. A mixture contains 24 ounces of chemical A and 30 ounces of chemical B. How can you fix the mixture to make the chemical compound?

Answers

Add 6oz of chemical B and remove 1/3 of the total mixture.
I might always be wrong.
Explanation:
Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B.
Take 1/3 of the total mixture to have 8oz of chemical A and 12oz of chemical B.

Hi! I hope this helps a bit because I'm just gonna give a few things you can talk about...I'm not writing a whole essay lol...

School impacts us in an extremely large variety of ways. Personally, I think it has more negative effects than positive. For example, at a school environment, there are so many ways to get exposed to profanity by your peers. There are definitely ways to be engaged with people who impact your entire life because of swearing. Similarly, students can learn and get very involved in having horrible behavior. Last but not least, I know that bullying is a huge problem at school. Even if it's being done unintentionally, students can really harm both the physical and mental strength of others.

What is the equation, in slope-intercept form, of the line with a slope of -1/3 and y-intercept of (0, 9)? Choices in picture below

Answers

Step-by-step explanation:

The formula is y=mx+b, with m representing the slope, x representing the x coordinate, and b representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.

Answer:

y=-⅓+9

Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?

Answers

Answer:

Kylie is 24 years old

Step-by-step explanation:

kylie = x

Bobby=x-5

x+x-5=43

2x-5=43

2x=43+5

2x=48

X=24 years old

19

If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

W-20.5=8 please help me

Answers

This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.

We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.

w-20.5+20.5=8+20.5

w=28.5

5./3

Answers

Answer:

the first one

Step-by-step explanation:

find the measure of each angle indicated and please explain how you got that answer if you can ​

Answers

#15- The answer should be 35.
In the photo I included, both points A and B are equal, because they are intersecting. To get the measurement for these angles, you add 40+40 to get 80. We know that three angles in a triangle need to add up to 180, so you would subtract 80 to get 100. If point A and B are 100, that means you can add 100+45 to get 145, and subtract that from 180 to get your answer. (35)

#16- The answer should be 42. Using the same logic as before, take away 80+40 from 180 to get 60 for points A and B. Then you would subtract 78+60 from 180 to get your answer. (42)

#17- The answer should be 108. You need to find the final angle of the triangle by subtracting 37+71 from 180. This would equal 72. Since the angle of a line is 180 degrees, you would subtract 72 from 180 to get the finished product. (108)

#18- The answer should be 35. You would start by finding the bottom left angle. You would use the same logic as I did in #17 by subtracting 180-126. This tells you that the bottom left angle in the triangle is 54. Then you would subtract 91+54 from 180 to get your answer. (35)

I hope this helps and that it wasn’t too confusing. #17 and #18 aren’t my strong suit, so I’m sorry if I’m wrong. Please mark brainliest!
