Answer:

11/6

Step-by-step explanation:

<u>Step 1: Convert to Improper fractions</u>

3 1/3 = 3*3/3 + 1/3 = 9/3 + 1/3 = 10/3

1 1/2 = 1*2/2 + 1/2 = 2/2 + 1/2 = 3/2

<u>Step 2: Make common denominators</u>

10/3 * 2/2 = 20/6

3/2 * 3/3 = 9/6

<u>Step 3: Subtract</u>

20/6 - 9/6

11/6

Answer: 11/6

22. What is the average rate of change over the interval (-3, 2)? SEE EXAMPLES

ivann1987 [24]

The average rate of change over the interval (-3, 2) is 1

<h3>Average rate of change</h3>

The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation

<h3>Interval</h3>

The interval is given as: (-3,2)

From the graph, we have:

f(-3) = -5
f(2) = 0

So, the average rate over these intervals is calculated as:

$m = \frac{f(b) - f(a)}{b -a}$

This gives

$m = \frac{f(-3) - f(2)}{-3 -2}$

Substitute known values

$m = \frac{-5- 0}{-3 -2}$

Simplify

$m = \frac{-5}{-5}\\\\$

$m =1$

Hence, the average rate of change is 1

Hi guys can u pls help me with this problem thanx

salantis [7]

Answer:

$\frac{1}{4}$ left

Step-by-step explanation:

The question says she used $\frac{1}{2}$ of it, so she probably used $\frac{1}{2}$ of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:

$\frac{3}{4}$ - $\frac{1}{2}$

make denominators equal

( $\frac{2}{2}$ × $\frac{3}{4}$ ) - ( $\frac{1}{2}$ × $\frac{4}{4}$ )

$\frac{6}{8}$ - $\frac{4}{8}$

$\frac{2}{8}$

$\frac{1}{4}$

Drinking 8 fluid ounces of milk provides 270.0 milligrams of calcium. How many fluid ounces of milk provide 72.5 milligrams of c

olga nikolaevna [1]

I believe this is a problem dealing with proportions, so you could cross multiply and divide. so you would do 8/270 then x/72.5 , you cross multiply 72.5x8 which equals 580. then you divide that answer by 100 which equals 5.8 (:
