Montel Edwards bought a 20-oz package of ham for $8.75. He can buy a 3-ib package of ham for $15.60. How much will he save per o

yawa3891 [41]

C. 11.3 cents per ounce

The 20-oz ham is $8.75/20 ounces = $0.4375/ounce

The 3-lb ham is 3 x 16 ounces = 48 ounces. Cost is $15.60/48 ounces = $0.325/ounce.

The difference in cost per ounce is 0.4375 - 0.325 = $0.1125 = 11.3 cents/ounce, rounded.

What is the slope of a line perpendicular to the line whose equation is

Amanda [17]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

To find the slope of the perpendicular line, we must first find the slope of the given line.

This can be done by rearranging the equation into the slope intercept form.

2x +3y= -3

3y= -2x -3

y= -⅔x -1

Thus, the slope of the given line is -⅔.

The slope of the perpendicular line is the negative reciprocal of the given line.

Slope of perpendicular line $= \frac{3}{2}$

What is slope-intercept form?

y= mx +c, where m is the slope and c is the y-intercept
This can be achieved by making y the subject of formula

Negative reciprocal

The reciprocal of m is $\frac{1}{m}$
The negative reciprocal of m is $- \frac{1}{m}$

Negative reciprocal of -⅔

$= - 1 \div ( - \frac{2}{3} )$

$= - 1 \times ( - \frac{3}{2} )$

$= \frac{3}{2}$

Does every line have an infinite number of lines that are perpendicular to the given line? Explain.

mel-nik [20]

Step-by-step explanation:

Basically you can have an infinite number of perpendicular lines to one line, one passing to each different point on your one line. ... So, in a space, you can have an infinite number of perpendicular lines to your one line, all of them passing through the same particular point.
