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?
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.

solve the system of equations y=x-4, y=-3x
To solve the given system of equations, we set y = x - 4 and y = -3x equal to each other to find x = 1 and subsequently y = -3, giving us the solution (1, -3). Other systems can be solved using methods such as elimination or substitution.
To solve the system of equations, let's start by setting up the equations provided:
1) y = x - 4
2) y = -3x
Since both equations equal y, we can set them equal to each other and solve for x:
x - 4 = -3x
4x = 4
x = 1
Now, we substitute x back into one of the original equations to find y:
y = 1 - 4
y = -3
The solution to the system of equations is (1, -3).
If we look at another set of equations mentioned in the question:
7x - 2y = 24
3x + 9y = 30
We can solve them using the method of elimination or substitution. For example, we can multiply the first equation by 3 and the second by 7, then subtract one from the other to eliminate one of the variables and solve for the other.

4ab over c divided by 3a over 2c
[tex]\frac{\frac{4ab}{c} }{\frac{3a}{2c} }[/tex] simplifies to (8b)/3.
To simplify the expression[tex]\frac{\frac{4ab}{c} }{\frac{3a}{2c} }[/tex]
1. Rewrite the expression using the rule that dividing by a fraction is the same as multiplying by its reciprocal:
[tex]\frac{\frac{4ab}{c} }{\frac{3a}{2c} }[/tex]=[tex]\frac{4ab}{c} *\frac{2c}{3a}[/tex]
2. Cancel out common factors:
- 'c' in the numerator and denominator cancels out.
- 'a' in the numerator and denominator cancels out.
3. After canceling, we're left with:
4b * ([tex]\frac{2}{3}[/tex])
4. Multiply 4b by [tex]\frac{2}{3}[/tex]:
4b * [tex]\frac{2}{3}[/tex] = [tex]\frac{8b}{3}[/tex]
So, [tex]\frac{\frac{4ab}{c} }{\frac{3a}{2c} }[/tex] simplifies to (8b)/3.
The probable question maybe:

8 story building each story was 15 4/5 in height how tall was the building
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]

Your friend has 5 more then twice as many game tokens as your sister. Let T be the number of game tokens your sister has. Write and expression for the number of game tokens your friend has
The number of game tokens that the friend has can be represented as the algebraic expression '2T + 5', where 'T' represents the number of game tokens the sister has.
Explanation:The question asks to express the number of game tokens your friend has in terms of 'T', the number of game tokens your sister has. As the information provided states, your friend has '5 more than twice' the amount which your sister has.
The mathematical expression for this will be '2T + 5', where 2T is twice the number of tokens your sister has and 5 is the extra tokens your friend has over twice your sister's total.
So, if your sister has 'T' number of game tokens, your friend will have '2T + 5' number of game tokens.

Hi!
Which of the following is closest to 0.0432
A) 4 times 10 to the power of negative 2
B) 4 times 10 to the power of negative 1
C) 4 times 10 to the power of positive 1
D) 4 times 10 to the power of positive 2
Final answer:
The exponential form closest to the number 0.0432 is 4 times 10 to the power of negative 2, because it gives us 0.04 which is very close to 0.0432. So the correct option is A.
Explanation:
The student is asking which exponential form is closest to the number 0.0432. To express a number in scientific notation, we move the decimal point to the right or left to create a new number from 1 up to 10, and then we multiply this number by 10 raised to a power that corresponds to the number of places the decimal point was moved.
If we look at the options given:
A) 4 times 10 to the power of negative 2 would be equivalent to 0.04, which is very close to 0.0432.B) 4 times 10 to the power of negative 1 is 0.4, which is much larger than 0.0432.C) 4 times 10 to the power of positive 1 is 40, andD) 4 times 10 to the power of positive 2 is 400, both of which are drastically larger than 0.0432.Therefore, the correct answer is A) 4 times 10 to the power of negative 2, because it is the option closest to 0.0432.
