To get an overall average of 90% from his six tests, Tim needs to score an average of 95% on his next two tests.

The subject of the question is Mathematics, and it is relevant to the Middle School grade.

To figure out the average score Tim needs on his next two tests to achieve a 90% overall average, we first need to calculate the total score that he needs. As Tim is taking six tests in total and wants an average of 90%, the total score he needs is 6 * 90 = 540

Then, we need to subtract the sum of his scores from the first four tests, which are 82%, 90%, 78%, and 100%. The sum of these four scores is 350.

Now, subtract this sum from the total score he needs, which is 540 - 350 = 190. This means that the total score Tim needs from his next two tests combined is 190%

Finally, to get the average score he needs on each of these next two tests, we divide this total by 2. 190 ÷ 2 = 95. Therefore, Tim needs to score an average of 95% on his next two tests to get an overall average of 90%.

A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once. 

There are many different methods in arriving to the final answer. However, errors cannot be perfectly avoided. One of these errors to mistakenly identify equations as linear. It is important that we know that the equations we are dealing with are of exact or correct  characteristics.

Answer:

24 posts

Step-by-step explanation:

Length = 8 yards

So, No. of parts of 1 yards in 8 yards = [tex]\frac{8}{1}= 8[/tex]

So, One each length there will be 8 posts including 2 corners

So, Total posts on 2 lengths = 8+8=16

Width = 6 yards

So, No. of parts of 1 yards in 6 yards = [tex]\frac{6}{1}= 6[/tex]

Excluding 2 corners, There will be 4 lamps on each width

So, Total posts on both widths excluding corners = 4+4=8

So, Total posts on fence = 16+8 = 24

Hence He used 24 posts .

Roxanna's normal hourly pay is $12.00.

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.

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]

The value of s (side) of rectangle is 8.66 inch.

Here,

The rectangle is divided into three squares.

The total area = 225 square inches.

We have to find the value of s (side).

What is area of square?

The area of square is the product of two equal side.

Now,

The rectangle is divided into three squares.

The total area is 225 square inches.

Hence, Area of rectangle = Total area of three squares

Let side of each square is ''a''

Then, Area of square = [tex]a^{2}[/tex]

Hence,

[tex]225 = a^{2}+a^{2}+a^{2}\\\\225 = 3a^{2}\\\\a^{2} = 75\\\\a = 8.6602[/tex]

The side of rectangle = 8.6602 inch

Now, The value of s to the nearest tenth is 8.66 inch.

Therefore, The value of s (side) of rectangle is 8.66 inch.

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.

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:

Therefore, the correct answer is A) 4 times 10 to the power of negative 2, because it is the option closest to 0.0432.

The ratio of the amount of money Mrs. O pays for swordfish to the amount she pays for salmon is 9:4, after calculating the price per pound based on the given information and the total paid.

The question involves finding the ratio of the amount of money Mrs. O pays for swordfish to the amount she pays for salmon. However, there seems to be a typo as the question asks for the ratio of the amount paid for swordfish to the amount paid for the same swordfish. We will resolve this by providing the correct ratio of the money paid for swordfish to the money paid for salmon.

Let us denote the price per pound of salmon as Ps. Given that "One pound of swordfish costs as much as 1.5 pounds of salmon", the price per pound of swordfish can be represented as 1.5Ps. We know Mrs. O pays $39 for 2 pounds of salmon and 3 pounds of swordfish combined.

Using this information, we can calculate the price Mrs. O paid for salmon:
Ps * 2 pounds of salmon. Similarly, the price for swordfish is: 1.5Ps * 3 pounds of swordfish.

Now we need to solve for Ps using the equation: 2Ps + (1.5Ps * 3) = $39. This simplifies to 2Ps + 4.5Ps = $39, resulting in 6.5Ps = $39. Dividing both sides by 6.5 gives us Ps = $6. Hence, Mrs. O pays $6 per pound for salmon.

Therefore, Mrs. O pays 2 * $6 = $12 for salmon and 3 * (1.5 * $6) = 3 * $9 = $27 for swordfish. The ratio of the money paid for swordfish to the money paid for salmon is $27 to $12, which simplifies to 9:4.

[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]
