ANSWER

The second statement is the contrapositive of the first.

EXPLANATION

If we have the conditional statement,

$x\Rightarrow \: y$

Then the converse of this statement is
$y\Rightarrow \: x$

The inverse of this statement is
$\neg \: x\Rightarrow \neg \: y$

and the contrapositive of this statement is
$\neg \: y\Rightarrow \neg \: x$

The correct answer is C.

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 1.5% syrup?

Alona [7]

Answer:

He needs 0.075 lbs of sugar and 4.925 lbs of water.

Step-by-step explanation:

Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.

Note

5 lbs - 100%

x lbs - 1.5%

Write a proportion:

$\dfrac{5}{x}=\dfrac{100}{1.5}$

Cross multiply:

$100x=5\cdot 1.5\\ \\100x=7.5\\ \\x=\dfrac{7.5}{100}=0.075$

So, he needs 0.075 lbs of sugar and 5 - 0.075 = 4.925 lbs of water.
