A text font fits 12 characters per inch. Using the same font, how many characters can be expected per yard of text? There are 12 inches in a foot, and 3 feet in a yard. 36 characters 144 characters 360 characters 432 characters
432 characters can be expected to fit per yard of text. Therefore, option D is the correct answer.
Given that, a text font fits 12 characters per inch.
We need to find how many characters can be expected per yard of text.
How to convert yards to inches?To convert a yard measurement to an inch measurement, multiply the length by the conversion ratio. The length in inches is equal to the yards multiplied by 36.
Let x be the number of characters to be used in a yard.
12 characters / in = x/ 36 in
(12 characters * 36 in) / in = x
x = 432 characters
Therefore, option D is the correct answer.

During a heavy rainstorm, a city in Florida received
12 1/4 inches of rain in 25 1/2 hours. What is the approximate rainfall rate in inches per hour?
Answer: 0.48 in
Step-by-step explanation:
The problem asks for unit rate. To solve, let's convert the fractions to decimals.
[tex]12\frac{1}{4} =\frac{49}{4} =12.25[/tex]
[tex]25\frac{1}{2}=\frac{51}{2}=25.5[/tex]
Now that they are in decimals, we can set up a proportion.
[tex]\frac{12.25 in}{25.5 hrs} =\frac{x}{1 hr}[/tex] [cross multiply]
[tex]12.25=25.5x[/tex] [divide both sides by 25.5]
[tex]x=0.48[/tex]
Now, we know that there was approximately 0.48 in of rainfall per hour.
Are the equations – 2x = 10 and -5x = 25 equivalent?
Answer: [tex]Yes[/tex]
Q: How are they the same answer?
A: You divide both of them by the number with x.
Divide both sides by -2
[tex]-2x/-2=10/-2\\x=-5[/tex]
Divide both sides by -5
[tex]-5x/-5=25/-5\\x=-5[/tex]
That's how both of them are equivalent to each other.

The boiling point of three components A, B and C of petroleum are 120○C, 70○C, 250○C respectively. If a mixture of these three is fractionally distilled, which of these will be obtained at the bottom of the distillation column?
Answer:
Mustaali Chill Bro
Component C, with a boiling point of 250°C, will be obtained at the bottom of the distillation column.
The component with the highest boiling point will be obtained at the bottom of the distillation column.
In this case, component C has the highest boiling point at 250°C, followed by component A at 120°C, and component B at 70°C. Therefore, during fractional distillation, component C will be obtained at the bottom of the distillation column.

Amy buy 5 pounds potatoes for $2.50. How much does 1 pound of potatoes weight? (What is the unit rate?)
Answer:
$0.50
Step-by-step explanation:
If there are 5 pounds of potatoes for $2.50, you must divide to find the unit rate.
$2.50 / 5 = $0.50
1 pound of potatoes costs $0.50
Answer:
0.5 $/pound
Step-by-step explanation:
[tex]5[/tex] pounds ⇒ [tex]2.50$[/tex]$to khow much dollars one 1 pound costs, we must divide the price of 5 pounds by 5
[tex]\frac{2.50}{5} = 0.5[/tex] $/ pound2.5 is in dollars and 5 is in pounds so the rate unit is $/pound
If y is directly proportional to x and y = 6 when x = 2, what is the proportion equation?
Answer:
y = 3x
Step-by-step explanation:
Direct proportion equation is
y = kx
6 = k*2
Divide each side by 2
6/2 = 2k/2
3 =k
The equation is y = 3x
Formula for direct proportion: y = kx
Solution:
6 = 2k
~Divide 2 to both sides
3 = k

For a given recipe, 10 cups of flour are mixed with 20 cups of sugar. How many cups of flour should be used if 4 cups of sugar are used? Assuming a constant ratio, fill out the table of equivalent ratios until you have found the value of x.
Answer:
2
Step-by-step explanation:
If 20 cups are used on the first recipe then 4 are used on the second, the way to find the answer is to divide 20 by 4. 20 divided by 4 will get 5. Now we have to divide the 10 cups of flour by 5 which in the end will get 2.

Step-by-step explanation:
[tex] \sf{4a - 2(3a + 8) = 6}[/tex]
Distribute 2 through the parentheses
[tex] \longrightarrow{ \sf{4a - 6a - 16 = 6}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{ - 2a - 16 = 6}}[/tex]
Move 16 to right hand side and change it's sign

Add the numbers: 6 and 16
[tex] \longrightarrow{ \sf{ - 2a = 22}}[/tex]
Divide both sides by 2
[tex] \longrightarrow{ \sf{ \frac{ - 2a}{ - 2} = \frac{22}{ - 2}}} [/tex]
Calculate
