8 0

Answer:

21 students

Step-by-step explanation:

the percent proportion is a/w = p/100

where A is a part of the whole W, and p% or p/100 is the percent

a/140 = 15/100 (Substitute w =140 and p= 15)

a times 100=140 times 15 (cross poducts property)

100a=2100  (Multiply)

100a/100 = 2100/100 (divide both sides by 100)

a = 21 (simplify)

So, 21 students win the award.

If you know that log5 (2) - log5 (12) = 0, which of the following is false?
garri49 [273]

Answer:

B

Step-by-step explanation:

A is correct because log_5(12) was added on both sides, which is supported by the Additive Property of Equality

C is correct because the Quotient Property of Logarithms states that log_bM-log_bN=log_b(\frac{M}{N} )

   so log_5(x)-log_5(12)=log_5(\frac{x}{12} ) is correct

D is correct because using the fact that log_5x=log_512 it is easy to figure out that x=12

For B, there is no property supporting that statement.
