Answer:

For soda =3/4

For coke= 3/5 X 3/4=9/20

Whole class is 1....

Therefore X% of 1 =9/20

Solving :

X/100 X 1 =9/20

X/100=9/20

20X =900

X= 900/20 = 45%

Identify the correct units to express the following idea.

hammer [34]

The units that we should use are gallons per day, we get:

$r = 2.4\frac{gallons}{day}$

<h3>Which units should we use?</h3>

We want to express the fact that every day you use 2.4 gallons of gasoline.

So we have two types of units in the above sentence, time (in days), and volume (of the gasoline consumed).

Then we conclude that the units that we should use is volume over time, particularly, gallons per day.

So we can represent that measure as:

$r = 2.4\frac{gallons}{day}$

If f(x)= x^2-2x+3, find the value of f (-2) and f(3)

AlexFokin [52]

Step-by-step explanation:

Given 

f(x) = x² - 2x + 3

Now

f(-2) = (-2)² - 2 * ( -2 ) + 3

 = 4 + 4 + 3

 = 11

f(3) = 3² - 2 * 3 + 3

 = 9 - 6 + 3

 = 12 - 6

 = 6

Hope it helps :)
