Which of the following terms are like terms?a) 9x and 9y b)12ac^2 and ac^2 c)8xy and 8xz d)ab^2 and x^2y

Answers

Like terms means terms that have the same variable (and with the same exponent). 

A) 9x and 9y <-- those are different variables. This is incorrect.

B) 12ac^2 and ac^2 <-- those are the same variables and same exponent. Correct.

C) 8xy and 8xz <-- different variables, incorrect.

D) ab^2 and x^2y <-- different variables, incorrect.

Correct answer is \fbox {B)}
Like terms are terms that have the same variables and also have the same exponents on those variables.

Out of all your choices, answer choice B) 12ac^2 and ac^2 fits that definition.

B is your answer.

A ratio of men to women in a party is exactly 3;2 if there are a total of 120 people at the party how many of them are women ? Can someone please explain to me how the answer is 48

Answers


If the ratio is 3:2 then you add that together to get 5.Which tell you what one group would equal. Then you divide 120 by 5 to get an answer of 24. If women is equal to 2 out of a total of 5, then you multiply 24 by 2 to get 48.

The resultant force, R, is related to two concurrent forces, X and Y, acting at right angles to one another, by the formula R2=X2+Y2. Rewrite the formula for Y.

Answers

R^2 = X^2 + Y^2
Y^2 = R^2 - X^2
Y = sqrt(R^2 - X^2)

Answer:

Y = √(R² - X²)

The cost of oranges varies directly as the number of oranges sold. If 8 oranges cost $10.40, how many oranges can be bought for $33.80? PLS HELPP MEE

I WILL MARK BRAINLIEST

Answers

Answer:

26

Step-by-step explanation:

if you can get 8 oranges for 10.40 then divide 10.40 by 8. you can get each orange for 1.3. you need to know how many oranges you can get for 33.8 so divide that by 1.3 and you get 26
8 oranges=10.40 so 8/10.40= .76923 (per orange)
So then 33.80/.76923= 43.94 oranges. So technically with 33.80$ you can buy 43 oranges and will have some change left

Given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line.

Answers

Here, 2x - 3y - 5 = 0

3y = 2x - 5

Divide the equation by 3, 
y = 2/3x - 5/3

Compare it with,y = mx + c
So, slope (m) = 2/3

In short,Your Answer would be: 2/3

Hope this helps!

True or false An invalid statistical test measure may have questions that are misinterpreted.

Answers

Answer: True.


Step-by-step explanation:  The motive of all statistical tests is to check whether all the variables or unknown quantities we are using in the test are independent of each other or are related among themselves.

Also, when we write an article, we should always check whether the statistical test we are using is suitable for the type of data concerned or not.

Furthermore, if a statistical test come out to be invalid, then it may be possible that there are some questions that are misinterpreted.

Thus, the answer is true.
True. An invalid statistical test measure may have questions that are misinterpreted.
