Answer/Step-by-step explanation:

1.a)(iv). \frac{1}{6} + (-\frac{7}{8}

Positive multiplied by negative = negative

\frac{1}{6} - \frac{7}{8}

\frac{4 - 21}{24} = \frac{-17}{24} = -\frac{17}{24}

2a.) 73.48 +(-37.3)

Note: + * - = -

73.48 - 37.3 = 36.18

3c.) 3\frac{3}{4} ÷ (-4\frac{2}{7})

Convert to proper fraction

\frac{15}{4} ÷ (-\frac{30}{7})

Change ÷ to × and flip the fraction on your right upside down

\frac{15}{4} * (-\frac{7}{30})

-\frac{15*7}{4*30}

-\frac{1*7}{4*2} = -\frac{7}{8}

3d.) -52.25 ÷ (-5.5) = \frac{-52.25}{-5.5}

(Note: - ÷ - = + )

\frac{-52.25}{-5.5} = 9.5

A contractor combined x tons of a gravel mixture that contained 10 percent gravel G, by weight, with y tons of a mixture that co
White raven [17]

Answer:

The value of x would be \frac{3}{5}y or \frac{3}{8}z

Step-by-step explanation:

Given,

x tons of 10% gravel G mixture is mixed with y ton of 2% gravel G to obtain  5% gravel mixture,

Thus, gravel G in x ton + gravel in y ton = gravel G in the resultant mixture,          

⇒ 0.1x + 0.02y = 0.05(x+y),

0.1x - 0.05x = 0.05y - 0.02y

0.05x = 0.03y

\implies x = \frac{0.03}{0.05}y=\frac{3}{5}y----(1)

Now, resultant mixture is z ton,

i.e. z=x+y

\implies y = z - x

From equation (1),

x=\frac{3}{5}(z-x) = \frac{3}{5}z-\frac{3}{5}x

x+\frac{3}{5}x=\frac{3}{5}z

\frac{8}{5}x=\frac{3}{5}z

x=\frac{3}{8}z

We are to find the Probability the someone buys a book that is paperback and fiction.

Let P(F) represents the event that the book is fiction and P(P) represents the event that the book is paperback. We are to find P(F∩P)

P(F∩P) = P(F) x P(P)

From the tree diagram we can see that:

P(F) = 0.45
P(P) = 0.65

Using the values, we get:

P(F∩P) = 0.45 x 0.65 = 0.2925

So, the Probability the someone buys a book that is paperback and fiction is 0.2925.

So, option B gives the correct answer
