A large bag or sugar weighs 7 1/2 lb. Gow Much does 1 1/4 bags of sugar weighs
arsen [322]

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that the weight of a large bag of sugar is 7\frac{1}{2}. This complex fraction can be written as

7\frac{1}{2}=\frac{14+1}{2}=\frac{15}{2}

So, the weight of a large bag of sugar is \frac{15}{2}.

The number of bags is 1\frac{1}{4}. It means the number of bags is number of bags is \frac{5}{4}.

1\text{ Bag}=\frac{15}{2}\text{ lb}

Multiply both side by \frac{5}{4}.

1\times \frac{5}{4}\text{ Bag}=\frac{15}{2}\times \frac{5}{4}\text{ lb}

\frac{5}{4}\text{ Bag}=\frac{75}{8}\text{ lb}

\frac{5}{4}\text{ Bag}=9\frac{3}{8}\text{ lb}

Therefore correct option is 4.

Use the properties of logarithms to expand the expression as a sum or difference, and/or constant multiple of logarithms. (Assum
Alecsey [184]

Answer:

\log_5(9)+\frac{1}{2}\log_5(x)-3\log_5(y)

Step-by-step explanation:

\log_5(\frac{9\sqrt{x}}{y^3})

First rule I'm going to use is the quotient rule:

\log_b(\frac{m}{n})=\log_b(m)-\log_b(n)

\log_5(9\sqrt{x})-\log_5(y^3)

Secondly, I'm going to rewrite the radical.

\sqrt{x}=x^\frac{1}{2}

\log_5(9x^\frac{1}{2})-\log_5(y^3)

Third, I'm going to use the product rule on the first term:

\log_b(mn)=\log_b(m)+\log_b(n)

\log_5(9)+\log_5(x^\frac{1}{2})-\log_5(y^3)

Fourth, I'm going to use power rule for both of the last two terms:

\log_b(m^r)=r\log_b(m)

\log_5(9)+\frac{1}{2}\log_5(x)-3\log_5(y)
