Question 30 (3.33 points)

son4ous [18]

Answer:

False.

Explanation:

Between 1870 and 1910, the number of Americans employed in agriculture fell by a third. This was due to the spread of new agricultural equipment. The main source of replenishment of the army of wage workers in the cities was the impoverished peasants who moved to the cities. The population moved from rural areas to cities in order to find work in large factories and manufactories.

4. Gary buys a 3 pound bag of cat food every 3 weeks. Gary feeds his cat the same amount of food

ira [324]

Answer:

Option A. $(\frac{7}{2})\frac{52}{3}$

Explanation:

<u><em>The complete question is</em></u>

Gary buys a 3 1/2 pound bag of cat food every 3 weeks. Gary feeds his cat the same amount of food each day. What expression could be used to determine the number of pounds of cat food his cat eats each year(1 year-52 weeks)

A. 7/2 x 52/3

B. 7/2 x 3/52

C. 3( 1/2 x 3/52 )

D. 3 ( 1/2 x 52/3 )

we can say that

The cat eats 3 1/2 pound bag of cat food every 3 weeks

Remember that

one year represent 52 weeks

using proportion

Find out the number of pounds of cat food his cat eats in 52 weeks (one year)

$\frac{3\frac{1}{2}}{3}\ \frac{pounds}{weeks}=\frac{x}{52}\ \frac{pounds}{weeks}$

Convert mixed number to an improper fraction

$3\frac{1}{2}\ pounds=\frac{3*2+1}{2}=\frac{7}{2}\ pounds$

substitute

$\frac{\frac{7}{2}}{3}\ \frac{pounds}{weeks}=\frac{x}{52}\ \frac{pounds}{weeks}\\\\x=(\frac{7}{2})\frac{52}{3}\\\\x=\frac{364}{6}\ pounds$

Convert to mixed number

$\frac{364}{6}\ pounds=\frac{360}{6}+\frac{4}{6}=60\frac{2}{3}\ pounds$

therefore

The expression is $(\frac{7}{2})\frac{52}{3}$

The number of pounds of cat food his cat eats each year is 60 2/3 pounds
