Alright, for 22: It doesn't matter how many 0's you add after the main digits (there's an official term for these digits, but I don't exactly recall it at this moment)
BASICALLY, 0's are just being used as placeholders AFTER the main digits, which in this case is 2.6
So, you can say 2.6, 2.60, 2.600, 2.6000, 2.60000000, but those 0's are meaningless really, because they all REALLY have the same value, 2.6. Your choice that they want is 2.06. You can't toss a 0 between the main digits without changing the value.
So, 22=2.06
Using the same methods as I said, notice how the main digits in 23 are 4.07. This is unchanging. Anything that gets tossed in between changes the numbers value. The answer they want is 4.70.
Using the same methods as above, notice how the main digits in 24 are 65.8. The answer they want, the choice that's different, is 65.08
Same thing for 25. The main digits are 37.06, so the choice they are looking for, the only one with a different value, is 37.6
For 26, three decimals that are equivalent:
For example: .5, .50, .500 are all equal.
For 27, rewrite these as fractions. That's easy.
In algebra, there are names for anything after the decimal. The first number that comes after the decimal is known as the "tenth", the second is known as the "hundredth", the third is known as the "thousandth", so on.
Applying that, we can convert these into fractions, using each decimals respective value as the denominator here.
.5 is in the tenth place, so as a fraction it's 5/10
.50 is in the hundredth place total, so as a fraction it's 50/100
.500 is in the thousandths place total (meaning this is where it ends), so it's 500/1000 as a fraction.
But in the end, ALL of these are the same value, 5/10

The length of a particular rectangle is 4 greater than the width of the rectangle. If the perimeter of the rectangle is 16, what is the area of the rectangle?
Answers
w+4=l <=length is 4 greater than width
2w+2(w+4)=24 <= plug in the l in the first equation with the second equation
2w+2w+8=24 <= solve the equation
4w=16
w=4
and, since
w+4=l <= length is 4 greater than width
then l=4+4
l=8
Open up the parenthesis with the distributive property, and you get 2x + 8 + 2x = 16.
Subtract 8 from both sides.
2x + 2x = 8
Or
4x = 8
/4 /4
x = 2
So therefore, since the width is x, then the width is 2. The length is x+4, or 6.
The area is length times width.
2×6 = 12
So the area of the rectangle is 12 square units.

8 story building each story was 15 4/5 in height how tall was the building
Answers
Final answer:
To calculate the height of an 8-story building, where each story is 15 4/5 feet tall, multiply the height of one story by the number of stories, resulting in a total height of 126.4 feet.
Explanation:
The question asks how tall a building would be if it has 8 stories, with each story being 15 4/5 feet in height. To find the total height of the building, you need to multiply the height of one story by the number of stories. The height of one story is 15 4/5 feet, which can also be written as 15.8 feet when converted to a decimal. Therefore, the calculation would go as follows:
15.8 feet/story × 8 stories = 126.4 feet
This calculation shows that the total height of the building is 126.4 feet. This example demonstrates how to apply multiplication in real-life scenarios, specifically in calculating the height of structures based on the height of individual stories.
Answer:
[tex]\displaystyle \frac{632}{5} \;units\;\text{or}\; 126\;\frac{2}{5}\;units \;\text{or}\; 126.4\;units[/tex]
Step-by-step explanation:
We can multiply the number of stories (8) by the height of each story (15 4/5 units) to find how tall the building is.
[tex]\displaystyle 8*15\frac{4}{5}=8*\frac{79}{5} =\frac{8*79}{5} = \frac{632}{5} \;units\;\text{or}\; 126\;\frac{2}{5}\;units \;\text{or}\; 126.4\;units[/tex]
Jin’s pays 3.48 for a bag of 12 tangerines find the unit price in dollars per tangerine if necessary round your answer to the nearest cent
Answers
Answer:
0.29
Step-by-step explanation:
Final answer:
To find the unit price of tangerines Jin bought, divide the total cost of $3.48 by 12. This gives a unit price of $0.29 per tangerine.
Explanation:
To find the unit price of the tangerines that Jin purchased, you need to divide the total cost by the number of tangerines.
Jin paid $3.48 for a bag of 12 tangerines. Therefore, to calculate the price per tangerine, use the following equation:
Unit Price = Total Cost / Number of Units
Unit Price = $3.48 / 12 tangerines
Unit Price = $0.29 per tangerine
If necessary to round to the nearest cent, the unit price remains $0.29 since it is already at the cent level.

A flat-screen television has a length that is 1 more inch than its width. The area of the television's screen is 1500 in cubed. To the nearest whole inch, what are the dimensions of the television
Answers
Final answer:
The dimensions of the flat-screen television with an area of 1500 square inches are approximately 38 inches in width and 39 inches in length.
Explanation:
To find the dimensions of a flat-screen television with an area of 1500 square inches and a length that is 1 inch more than its width, we can set up a quadratic equation. Let the width be w inches, then the length would be w + 1 inches. The area of the television's screen is given by the formula:
Area = width × length
Substituting the given values, we get:
1500 = w × (w + 1)
This simplifies to:
w² + w - 1500 = 0
Solving this quadratic equation, we find two potential solutions for w, but only the positive value makes sense in this context. Once we find the value of w, the width, we can then add 1 to get the length.
After calculating, we find that the width w is approximately 38 inches, and the length is approximately 39 inches. Therefore, the dimensions of the television are 38 inches by 39 inches to the nearest whole inch.

Answers
Answer:
The midpoint of HK is (-4, 1)
Step-by-step explanation:
We are given two coordinates H(-1, 2) and K(-7, -4)
We need to find the midpoint of HK.
We have formula to find the midpoint.
[tex](\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2} }[/tex]
Here [tex]x_1 = -1, y_1 = 2, x_2 = -7 and y_2 = -4[/tex]
Now plug in these values in the above formula, we get
[tex](\frac{-1 + (-7)}{2} , \frac{2 +(-4)}{2} )[/tex]
[tex](\frac{-8}{2}, \frac{-2}{2} ) = (-4, -1)[/tex]

Elio Makes candles that are 14 cm tall. Each candle burns eight hours before going out. He is wondering how many hours a 21 cm tall candle can burn for.
Answers
Final answer:
A 21 cm tall candle should burn for 12 hours, as it is 1.5 times taller than a 14 cm candle which burns for 8 hours.
Explanation:
The problem is one of direct proportion where the height of the candles is directly proportional to the burning time. If a 14 cm tall candle burns for 8 hours, then a 21 cm tall candle, which is 1.5 times taller, should burn for 1.5 times longer. Hence, to calculate the burning time for the 21 cm candle, we multiply 8 hours by 1.5.
Calculation:
21 cm / 14 cm = 1.5
8 hours × 1.5 = 12 hours
Therefore, a 21 cm tall candle should burn for 12 hours.

Roxanna earns 1.5 her normal hourly rate for overtime pay. Last week, Roxanna earned 72.00 I'm overtime pay for 4 hours. What is Roxanna's normal hourly pay?
Answers
Roxanna's normal hourly pay is $12.00.
Explanation:To find Roxanna's normal hourly pay, we need to first calculate her overtime pay rate. We know that she earns 1.5 her normal hourly rate for overtime pay. Since she earned $72.00 in overtime pay for 4 hours, we can set up an equation to solve for her normal hourly pay:
Overtime Pay = Normal Hourly Pay × Overtime Hours × Overtime Rate
$72.00 = Normal Hourly Pay × 4 × 1.5
Simplifying the equation, we have:
Normal Hourly Pay = $72.00 / (4 × 1.5)
Normal Hourly Pay = $72.00 / 6
Normal Hourly Pay = $12.00
Therefore, Roxanna's normal hourly pay is $12.00.

Assuming the lines are parallel, then refer to the image attachment for the angle labels
A = 14-4x
B = A = 14-4x
C = 5y-9
D = 8y+42
E = 180 - D = 180 - (8y+42) = -8y+138
B+C = 90
(14-4x)+(5y-9) = 90
-4x+5y+5 = 90
-4x+5y = 85
If the lines are parallel, then
A = E
14-4x = -8y+138
-4x+8y = 124
The system of equations is
-4x+5y = 85
-4x+8y = 124
Subtract equation 2 from equation 1 to get
-3y = -39
y = 13
Then use that y value to find x
-4x+8y = 124
-4x+8*13 = 124
-4x+104 = 124
-4x+104-104 = 124-104
-4x = 20
x = -5
So the final answer is x = -5
Once again this all depends on if the two lines are parallel.
