Answer:

Part 1) The unit rate is $16\frac{dollars}{ounce}$

Part 2) The unit rate is $\frac{1}{4}\frac{dollars}{ounce}$

Part 3) The unit rate is $\frac{1}{4}\frac{dollars}{ounce}$

Part 4) The unit rate is $4\frac{dollars}{ounce}$

see the attached figure

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{d2-d1}{n2-n1}$

where

d ----> number of dollars (dependent variable or output value)

n ---> number of ounces (independent variable or input value)

Remember that the slope of the linear equation is the same that the unit rate

<u><em>Verify each case</em></u>

1) we have

$d=16n$

This is a proportional relationship between the variables d and n

The slope is

$m=16\frac{dollars}{ounce}$

therefore

The unit rate is $16\frac{dollars}{ounce}$

2) we have

<em>First table</em>

take two points from the table

(4,1) and (16,4)

substitute in the formula of slope

$m=\frac{d2-d1}{n2-n1}$

$m=\frac{4-1}{16-4}$

$m=\frac{3}{12}\frac{dollars}{ounce}$

simplify

$m=\frac{1}{4}\frac{dollars}{ounce}$

therefore

The unit rate is $\frac{1}{4}\frac{dollars}{ounce}$

3) we have

$n=4d$

This is a proportional relationship between the variables d and n

isolate the variable d

$d=\frac{1}{4}n$

The slope is

$m=\frac{1}{4}\frac{dollars}{ounce}$

therefore

The unit rate is $\frac{1}{4}\frac{dollars}{ounce}$

4) we have

<em>Second table</em>

take two points from the table

(1,4) and (2,8)

substitute in the formula of slope

$m=\frac{d2-d1}{n2-n1}$

$m=\frac{8-4}{2-1}$

$m=4\frac{dollars}{ounce}$

therefore

The unit rate is $4\frac{dollars}{ounce}$

Plz help me ith this one

garri49 [273]

Answer:

There Equal

Step-by-step explanation:

Because a 0 behind a significant number has no value and if it has no value then you can keep adding zeros behind it and it would still be equal because like i said the zeros behind the important numbers has no value

Write an expression to represent each of the following sketches. Then give the value of each sketch.

zysi [14]

The sketches are illustrations of inequalities

<em>The first sketch is: </em> $-2 \le x \le 5$ <em>.</em>
<em>The second sketch is: </em> $3 \ge x \ge -4$ <em />

<em />

<u />

<u>Sketch A</u>

In sketch A, we have the following observations:

<em>The arrow faces left (this implies less than)</em>
<em>The dots on -2 and -5 are closed dots (this implies less than or equal to).</em>

<em />

Hence, the inequality is:

$-2 \le x \le 5$

<u />

<u>Sketch B</u>

In sketch B, we have the following observations:

<em>The arrow faces right (this implies greater than)</em>
<em>The dots on -4 and 3 are closed dots (this implies greater than or equal to).</em>

<em />

Hence, the inequality is:

$3 \ge x \ge -4$
