Answer:
the way you have the question on here is weird, but I'm pretty sure the answer is 5
Step-by-step explanation:
molecules are groups of bonded atoms, so one molecule of Butane would be C4H10 by itself, but if you have 5 of those, you have 5 molecules.
however, if you're talking about the number of ATOMS in one molecule of Butane, there would be 14 (4 carbon, 10 hydrogen)

The equation 2x - 4y - 8 models the relationship between x and y. What is the rate of change of y with respect tox?
Answer:
1/2Step-by-step explanation:
Given the equation 2x-4y = 8 models the relationship between x and y
The rate of change of y with respect to x is known as the slope of the line.
The standard form of equation of a line is y = mx+c where;
m is the slope
c is the intercept
Rewrite the equation in its standard form as shown:
2x-4y = 8
-4y = -2x+8
-4y/-4 = -2x/-4 + 8/-4
y = 1/2 x -2
On comparison, the slope m is 1/2
Hence the rate of change of y with respect to x is 1/2
The graph shows the printing rate of printer a printer b can print a rate of 25 pagws per minute how does the rate for printer b compare
Answer:greater,greater,15

What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
As, slope for printer A= 30-2/2-0
= 30/2 = 15 pages per minute.
So, the rate of Printer A is 15 pages per minute.
Thus,
The rate for Printer B is greater than the rate for Printer A because the rate of 25 pages per minute is greater than the rate of 15 pages per minute for Printer A.

Write an equation that is parallel to y = 9x and goes through the point (1,5).
Answer:
y=9x-4
OR
y-5=9(x-1)
(both are correct and equal)
Step-by-step explanation:
Parallel means slope is the same, so the slope of the equation should be 9.
Using point slope form:
[tex]y-5=9(x-1)[/tex]
Which would be:
[tex]y=9x-4[/tex]

Examine the supply and demand schedules for laptops. How much would a
seller charge if he or she wanted to sell laptops for their equilibrium price?
Answer:
$400
Step-by-step explanation:
the seller would charge $400 if he or she wanted to sell laptops for their equilibrium price.
What is the equilibrium price?Demand and supply forces are balanced at an equilibrium price. Prices have the propensity to revert to this equilibrium unless certain demand or supply characteristics alter. When demand, supply, or both move or change, the equilibrium price will change.
neither a deficit nor a surplus exists unless a demand or supply determinant changes. When the price of a good or service changes and there is a shortage, this indicates that buyers want to purchase more than what producers are willing to sell.
Demand exceeds the supply in this situation, leaving customers unsatisfied. The opposite is true if a price shift results in a surplus, which indicates that customers wish to purchase fewer units than are being provided by producers.
In the given dataset, we can see that Demand and supply are equal at the price of laptops 400$.
Therefore, the seller would charge $400 if he or she wanted to sell laptops for their equilibrium price.

You work at an appliance store that offers an extended warmanty on each product sold. The store sold 12,930 appliances and two-fifths of the customers purchased the extended warranty. How many extended warrantles were purchased?
Answer:
5,172
Step-by-step explanation:
When figuring out a fraction of a number (especially of total things sold to find out the number of a certain thing purchased), remember that you are multiplying. So when finding 2/5 of 12,930, just multiply 12,930 by 2/5 (or, in decimal form, .4) and that will give you 5,172. Hope this helps!

Solve for AB. Round your answer to the nearest tenth if necessary.
Answer:
See Below
Step-by-step explanation:
You want to find AB.
They give the equation for AB, BC, and AC
AC - BC = AB
substitute the equations
(30) - (8x + 3) = 6x + 8
30 - 8x - 3 = 6x + 8
27 - 8x = 6x + 8
+8x +8x
27 = 14x + 8
-8 -8
19 = 14x
19/14 = 14x/14
1.3571428 = x

Genevieve's is 4 square yards. Convert their garden sizes to the same units (feet) to determine who's garden has a
larger area. (1 point)
Genevieve's garden is 12 square feet and thus, has a smaller area than Esmeralda's
Genevieve's garden is 16 square feet and thus has a smaller area than Esmeralda's
O Genevieve's garden is 25 square feet, and thus has the exact same area as Esmeralda's
Genevieve's garden is 36 square feet, and thus, has a larger area than Esmeralda's
Answer:
Genevieve's garden is 12 square feet and thus, has a smaller area than Esmeralda's
Step-by-step explanation:
Given:
Esmeralda's garden = 25 square feet
Genevieve's garden = 4 square yards
Convert Genevieve's units (yards) to feet
Yards to feet
1 yard = 3 feet
4 yards = 4 * 3 feet
4 yards = 12 feet
Genevieve's garden = 12 square feet
Genevieve's garden is 12 square feet and thus, has a smaller area than Esmeralda's
Answer:
The answer is: Genevieve's garden is 36 square feet, and thus, has a larger area than Esmeralda's

Berries : Oranges = 10 : 1
Let the number of berries = x
10 : 1 = x : 25
Product of means = 1*x = x
Product of extremes = 10 * 25 = 250
Product of means = product of extremes
x = 250
