Iron is typically alloyed for commercial uses because it reacts easily with air and water, leading to corrosion. By creating alloys such as steel with added elements like carbon and chromium, iron becomes more robust and rust-resistant, lending itself to a wider range of applications.
The reason iron is usually made into an alloy for commercial uses is that iron reacts easily with air and water, which is option C. Commercial alloys of iron, like steel, are produced by adding elements such as carbon and metals like manganese, chromium, nickel, tungsten, molybdenum, and vanadium. These elements create an alloy that is more resistant to corrosion (rusting), and they can be engineered to have different properties suitable for specific applications. For example, stainless steel contains chromium which helps in forming a protective oxide layer on the surface, thereby protecting the base iron from rusting.
While wrought iron, which is a commercially pure iron containing less than 0.2% carbon, is quite resistant to rust and is malleable and ductile, it has largely been replaced by mild steel. Mild steel, though not as corrosion-resistant as true wrought iron, is more cost-effective and widely available. Therefore, the commercial use of iron predominantly involves its transformation into alloys that benefit from enhanced strength, durability, and corrosion resistance.

Karma was given some birthday money. She put the money in an account. Every month after that, she deposits the same amount of money.
The equation that models this situation is y=75x+60, where y is the amount of money in the account and x is the number of deposits.
What does the y-intercept mean in this situation.
The y-intercept means that Karma was given $60 for her birthday. Therefore, option C is the correct answer.
The given equation that models the given situation is y=75x+60.
What is the y-intercept?The y-intercept of a graph is the point where the graph intersects the y-axis.
We know that the x-coordinate of any point on the y-axis is 0. So the x-coordinate of a y-intercept is 0.
Now, Graph the line using the slope and y-intercept, or two points.
Slope: 75
y-intercept: (0, 60)
The coordinates to plot the graph is (0, 60) and (1, 135).
Here, in the graph, if we then look at the y-intercept we can see that the function crosses the y-axis at a value of 60.
Therefore we can safely say that the y-intercept means that Karma was given $60 for her birthday.
The y-intercept means that Karma was given $60 for her birthday.

A. 4 gallons IF RIGHT I'LL GIVE BRAINLIEST
B. 8 gallons
C. 40 gallons
D. 80 gallons
Answer:
The answer is option A : 4 gallons.
Step-by-step explanation:
A recipe for 10 servings of raspberry sorbet calls for 2 cups of water, 1/1.2 cups of granulated sugar, and 4 cups of frozen raspberries.
Now 10 servings need = 2 cups of water.
And 320 servings will need = [tex]\frac{2}{10}\times320= 64[/tex] cups of water.

A merchant wishes to blend 200 pounds of coffee worth $3.20 a pound from two mixtures: one at $3.00 a pound and the other at $3.25 a pound. How many pounds of each mixture should he use?
To create the ideal blend, the merchant should combine 40 pounds of coffee worth $3.00 per pound and 160 pounds of coffee worth $3.25 per pound.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Let's call the amount of coffee worth $3.00 per pound "x" and the amount of coffee worth $3.25 per pound "y".
We know that the total amount of coffee is 200 pounds, so we can write the equation:
x + y = 200
We also know that the total cost of the coffee is $3.20 per pound times 200 pounds, or $640. So we can write another equation based on the cost:
3.00x + 3.25y = 640
Now we have two equations with two variables, so we can solve for x and y.
Let's start by solving for x in the first equation:
x + y = 200
x = 200 - y
Now we can substitute this expression for x into the second equation:
3.00x + 3.25y = 640
3.00(200 - y) + 3.25y = 640
600 - 3.00y + 3.25y = 640
0.25y = 40
y = 160
So we know that the merchant needs to use 160 pounds of coffee worth $3.25 per pound.
We can use the first equation to solve for x:
x + y = 200
x = 40
So the merchant needs to use 40 pounds of coffee worth $3.00 per pound.
Therefore, the merchant should use 40 pounds of coffee worth $3.00 per pound and 160 pounds of coffee worth $3.25 per pound to make the desired blend.

The difference in lengths of the posters is 0.40 meters, calculated as [tex]\( |1 - 0.55 - 0.85| = 0.40 \)[/tex].
Step 1:
Find the length of Orlando's poster:
Orlando's poster is 0.55 meters less than 1 meter. Subtract 0.55 meters from 1 meter.
[tex]\[ \text{Length of Orlando's poster} = 1 - 0.55 \][/tex]
Step 2:
Calculate the difference in lengths:
Subtract the length of Amanda's poster (0.85 meters) from the length of Orlando's poster obtained in step 1.
[tex]\[ \text{Difference in lengths} = \text{Length of Orlando's poster} - \text{Length of Amanda's poster} \][/tex]

Mr Leonard wants to top-up his central heating oil tank.
The oil tank can take up to 1200 litres of oil. There are already 450 litres of oil in the tank.
The price of oil is 81.5p per litre. As a loyal customer, Mr Leonard gets a 7.5% discount on the price of the oil.
How much discount does Mr Leonard get on this purchase? Give your answer in £
Answer:
The discount is 4584.375 p.
Step-by-step explanation:
Given : The oil tank can take up to 1200 litre of oil. There are already 450 litres of oil in the tank.
The price of oil is 81.5p per litre . As a loyal customer, Mr Leonard gets a 7.5% discount on the price of the oil.
To find : How much discount does Mr Leonard get on this purchase?
Solution :
First we find out the number of litre required in the tank
Total capacity of tank = 1200 litre of oil
There are already 450 litres of oil in the tank.
The required oil is = 1200 L – 450 L = 750 L
The price of oil is 81.5 p per litre.
i.e, 1 liter oil price is = 81.5 p
For 750 liter oil price is = [tex]81.5\times 750=61125p[/tex]
There is 7.5% discount on the price of oil.
i.e, [tex]61125\times\frac{7.5}{100}=4584.375[/tex]
The discount is 4584.375 p.
The discount Mr Leonard receives on his purchase is £45.84.
What is a discount?A discount is a reduction in the price of a good or service. After a discount, the price of an item becomes cheaper.
What is the discount on the purchase?Quantity of oil that would be bought = capacity of the oil tank - oil already in the tank
1200 - 450 = 750 liters
Total cost of the 750 liters = total liters to be bought x cost per liter
750 x 81.5 = 61,125 p =£611.25
Value of the discount = 7.7% x £611.25 = £45.84

The height h, in inches, of the juice in the pitcher shown at the right is a function of the amount of juice j, in ounces, that has been poured out of the pitcher. write a function rule that represents this situation. what is the height of the juice after 47oz have been poured out?
The pitcher shown has a height of 10 inches and a volume of 64 oz. The pitcher has a shape of cylinder and the volume formula of cylinder is:
V = π r^2 h
So given volume and height, we can find for the radius:
64 = π r^2 (10)
r = 1.427
So for a 47 oz volume is poured out, what remains is:
V remain = 64 oz – 47 oz = 17 oz
So the height at a volume of 17 oz is:
17 = π (1.472)^2 h
h = 2.66 inches
To determine a function rule between the height of the juice and the amount poured out, we need additional specifics such as initial height and pitcher capacity. Without this, we cannot define the exact function or determine the juice height after pouring out 47 ounces.
To write a function rule that represents the relationship between the height of juice h in the pitcher and the amount of juice j poured out, we need additional information about the initial height of the juice when the pitcher is full and its capacity. Without this information, we cannot construct an exact function. Generally, if 'H' is the initial height and 'C' is the capacity of the pitcher in ounces, then the function could look something like h = H - (k x j), where 'k' is a constant that converts ounces to inches based on the shape of the pitcher.
Regarding the second part of the question, without a specific function or more information about the pitcher, we cannot determine the height of the juice after 47 ounces have been poured out.
