Solution:

Given:

$\frac{a}{b}\cdot\frac{c}{d}$

Since b and d are nonzero elements, then it is the product of two rational numbers.

Multiplying two rational numbers produces another rational number.

Therefore, the product is a rational expression.

OPTION C is the correct answer.

Let the equation C= 2.32 N + 34,180 represent the cost of raising a child, C on an income, N. If the Corlone family has an incom

Genrish500 [490]

Answer:

$126,980

Step-by-step explanation:

Given the equation C = 2.32N + 34,180 where 'C' is the cost of raising a child and 'N' is the income. If the Corlone family has an income of $40,000, you can use this value for 'N' and solve for 'C':

C = 2.32(40,000) + 34,180

C = 92,800 + 34,180

C = $126,980

A field is a rectangle with a perimeter of 1260 feet. The length is 100 feet more than width. Find the width and length of the r

lyudmila [28]

To solve this problem you must apply the proccedure shown below:

1. The formula for calculate the perimeter of a rectangle is:

$P=2L+2W$

Where $L$ is the length and $W$ is the width.

2. The length is $100ft$ more than the width, therefore:

$L=W+100$

3. Substitute values into the formula for calculate the perimeter and solve for the width:

$1260=2(W+100)+2W\\ W=265ft$

3. Then, the length is:

$L=265ft+100ft\\ L=365ft$

The answer is: The length is $365ft$ and the width is $265ft$

A school track is shown the straightaway on each side measures 1,000 meters the curves are semicircles with diameter 74 meters w

lisov135 [29]

Answer:

2232.48 meters

Step-by-step explanation:

From the diagram:

Radius of semicircle = 74

Length of straightway on each side = 1000

The length of school track :

Straightway on each side = 2 * 1000 m = 2000m

Length of semicircle = πr/2

Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785

Total Length = ( 2000 + 232.47785) = 2232.48 meters
