Which of the following expressions does not represent “increase a quantity n by 25%”?
A. n + 0.25n
B. (1 + 0.25)n
C. 125n
D. 1 1/4 n ( one and one forth n)

Option C) 125n is the expression that does not represent “increase a quantity n by 25%

Step-by-step explanation:

The given expressions are for the quantity n which is increased by 25%.

Option A) n + 0.25n

Put n = 100,

⇒ 100 + 0.25(100)

⇒ 100 + 25

⇒ 125

So, option A) represents the given condition.

Option B) (1 + 0.25)n

Put n = 100,

⇒ (1+0.25) 100

Multiply 100 with each terms inside the bracket.

⇒ 100 + 25

⇒ 125

So, option B) represents the given condition.

Option C) 125n

Put n = 100,

⇒ 125 × 100

⇒ 12500

So, option C) does not represents the given condition.

Option D) 1 1/4 n

Put n = 100,

Convert the mixed fraction to proper fraction

⇒ (5/4) n

⇒ (5/4) 100

⇒ 500 / 4

⇒ 125

So, option D) represents the given condition.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
