Answer:
Step-by-step explanation:
Like terms are the terms which have the same variable and same exponent. It is not necessary that the coefficient is equal.
For example ab and 4ab are like terms because both the expression have the same variable a, b and exponent is also equal.
Looking into the given options, we can conclude that the expressions 2xy, -xy,1/2xy are like terms.
Hence, the like terms are
Answer:
(1-0.01p)/n
Step-by-step explanation:
Mathematically;
Percentage of student playing at least one sport = 100% - Percentage of students playing no sport
Mathematically, that would be;
Percentage playing no sport = 100% - p%
So, to find this in n 7th graders
we have;
(100-p)/100 * n
= 100-P/100n = 1/n - P/100n
= 1/n - 0.01p/n
= (1-0.01p)/n
Answer:

The value that of the expression when n= -3 as in the task content is; Choice D; -9; First step is 3(2).
<h3>What is the value of the expression as given in the task content when n = -3?</h3>
It follows from the task content that the value of the expression can be determined as follows;
n² - 3(2) + 4n
= n² - 6 + 4n
= (-3)² - 6 +4(-3)
= 9 -6 -12
= -9.
Ultimately, the first step by PEMDAS guidelines is; 3(2) and the correct choice is D.

Answer:
i. weight of wastage(kg) = 179.775 kg
ii. weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg
percentage of rice cultivated = 100 - 23.5 = 76.5%
Step-by-step explanation:
A land of 1000 sq. meter is used to cultivate 765 kg of rice with wastage of 23.5%.
i. The wastage in percentage is 23.5% but the weight of the wastage in weight is 23.5% of 765 kg
weight of wastage = 23.5/100 × 765
weight of wastage = 17977.5/100
weight of wastage(kg) = 179.775 kg
ii. weight and percentage of rice cultivated.
weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg
percentage of rice cultivated = 100 - 23.5 = 76.5%
