7. During the Middle Ages, people often used grains, scruples, and drahms to measure the weights of different medicines. If 120 grains are equivalent to 6 scruples and 6 scruples are equivalent to 2 drahms,

how many drahms are equivalent to 300 grains? Explain your reasoning. If you get stuck, try creating a table.


Answers

Answer:

5 drahms.

Step-by-step explanation:

From the question given above, the following data were obtained:

120 grains = 6 scruples

6 scruples = 2 drahms

300 grains (in drahms) =..?

From the above data,

120 grains = 6 scruples

6 scruples = 2 drahms

Therefore,

120 grains = 2 drahms

Thus, we can obtain 300 grains in drahms as follow:

120 grains = 2 drahms

Therefore,

300 grains = 300 grains × 2 drahms /120 grains

300 grains = (300 × 2)/120 drahms

300 grains = 5 drahms

Therefore, 300 grains is equivalent to 5 drahms.

The equation 2x - 4y - 8 models the relationship between x and y. What is the rate of change of y with respect tox?

Answers

Answer:

1/2

Step-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

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?

Answers

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.

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.
