Answer:

Option b.

Step-by-step explanation:

The given table represents the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe.

Using the table we get

$\dfrac{\text{Number of cups of cereal}}{\text{Number of cups of raisins}}=\dfrac{8}{2}=\dfrac{12}{3}=\dfrac{16}{4}=4$

It means the number of cups of cereal is 4 times the number of cups of raisins in a cereal bar recipe.

Maria plotted an equivalent ratio on the coordinate grid.

The horizontal axis label is Cereal in cups and the vertical axis label is Raisins in cups.

x-coordinate = Cereal in cups

y-coordinate = Raisins in cups

A point is plotted on the ordered pair (80, 10).

We know that number of cups of cereal is 4 times the number of cups of raisins.

$\dfrac{80}{4}=20$

Here number of cups of Cereal is 80. So, the number of cups of raisins must be 20.

If the number of cups of cereal is 80, then the number of cups of raisins will be 20.

Therefore, the correct option is b.

What is the mass of 2.5 moles of carbon dioxide?

GarryVolchara [31]

Answer:

110 grams

Step-by-step explanation:

CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).

So first finding the mass of 1 molecule of CO2 which is equals to

= mass of 1 carbon atom + masses of 2 oxygen atom, we get

= 12+(16*2)= 12+32= 44 a.m.u.

Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )

1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams

So our answer is 110 grams.

Create the f(x) function based on the table. Your answer should be in function notation. X f(x) - 10 -6 -9 -5 1-8 -4 -7 1-3 5 9

Minchanka [31]

Answer:

$f(x) = x + 4$

Step-by-step explanation:

First create an equation in slope-intercept form, y = mx + b. To do this, find the rate of change or slope (m), and the y-intercept (b).

Using two pairs, (-7, -3) and (-8, -4),

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-3)}{-8 -(-7)} = \frac{-1}{-1} = 1$

m = 1

To find b, substitute m = 1, x = -7 and y = -3 into y = mx + b.

Thus:

-3 = (1)(-7) + b

-3 = -7 + b

-3 + 7 = b

4 = b

b = 4.

Replace y with f(x), m with 1 and b with 4 in y = mx + b.

The function would be:

$f(x) = x + 4$
