The volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder, displacing the level to 47.6 ml.
What is volume?
It is defined as a three-dimensional space enclosed by an object or thing.
We have:
Volume of the water filled in the cylinder = 41.5 ml
Volume after placing the piece of granite = 47.6 ml
The volume of the piece of granite = 47.6 - 41.5 = 6.1 ml
As we know 1 ml = 1 cm³
The volume of the piece of granite = 6.1 cubic cm
Thus, the volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml.

Wrote a system of equations that can be used to find how much one hamburger and one Order of fries cost.
Answer:
System of equations:
9x+3y=24.75
6x+4y=19.50
x: cost of a hamburger
y: cost of an order of fries

Step 1
Factor the variable y in the right side
[tex]a=y(9+3x)[/tex]
Step 2
Divide by [tex](9+3x)[/tex] both sides
[tex]a/(9+3x)=y(9+3x)/(9+3x)[/tex]

What is a fundraiser?A fundraiser is an event which is intended to raise money for a particular purpose, for example, for a charity.
Given that, A School raised $13,809 during its fall fundraiser and $20,786 during its winter fundraiser. The total fundraising goal for the school year is $50,000.
The yet total fundraised = fall fundraiser + winter fundraiser
= $13,809 + $20,786
= $34595
Since, they need $50000 in total,
Therefore, remaining amount = total - collected
= $50000 - $34595
= $15405.
Hence, the extra fundraiser school should get is $15405.

Jane ran 3/8 of the distance that Jack ran. If Jane ran 2/3 of a mile, how far did Jack run?
Which of these could be used to solve the problem?
A. 3/8 * = 2/3
B. 2/3 * = 3/8
C. x=(2/3) (3/8)
D. x=3/8 *- 2/3*
Using proportions, it is found that the distance that Jack ran is given by:
A. [tex]\frac{3}{8}x = \frac{2}{3}[/tex]
The distance ran by Jane was of [tex]\frac{2}{3}[/tex] of a mile.This distance was also [tex]\frac{3}{8}[/tex] of the distance ran by Jack, which is given by x.Applying the proportion, we have that [tex]\frac{3}{8}[/tex] multiplied by x is equals to [tex]\frac{2}{3}[/tex], hence:
[tex]\frac{3}{8}x = \frac{2}{3}[/tex]

if a debt of $480 is reduced by 20% find the new debt
To find the new debt after a 20% reduction, subtract 20% of the original debt from the original debt.
Explanation:To find the new debt after a 20% reduction, we need to subtract 20% of the original debt from the original debt. Here's how to calculate it:
Convert 20% into a decimal by dividing it by 100: 20% = 0.20Multiply 0.20 by $480 to find the reduction amount: 0.20 x $480 = $96Subtract $96 from $480 to find the new debt: $480 - $96 = $384Therefore, the new debt after a 20% reduction is $384.
The new debt after being reduced by 20% is $384.
Explanation:To find the new debt after it has been reduced by 20%, we can use the following steps:
Calculate 20% of $480 by multiplying 480 by 0.20. 20% of 480 is $96.Subtract the amount calculated in step 1 from the original debt. The new debt is $480 - $96 = $384Therefore, the new debt after being reduced by 20% is $384.

A doctor's office has a computer file showing the heights of 100 male patients of one of the doctors of the practice. the heights range from 18 inches to 68 inches. by accident, the greatest height has been recorded as 680 inches, instead of 68 inches. (a) does this affect the average? if so, by how much? (b) does this affect the median? if so by how much?
The effect of the mistake is:
The mean value obtained is larger. The median value is not affected.The average value recorded is larger than it actually is. Hence , the average value is affected by the mistake. Given the information supplied, we can only deduce that the mean value will be greater than the actual average.
The mean involves taking the sum of all the values and dividing it by the number of values.
Using a value of 680 instead of 68 will mean that, the sum obtained is greater than the actual sum.
The median on the other hand isn't affected by this error, because, the arrangement of the values isn't changed.
The sorting of values is very crucial to calculating the Median. However, either 68 or 680. The position of the maximum value remains unchanged.

A chemist has two large containers of sulfuric acid solution, with different concentrations of acid in each container. Blending 305 mL of the first solution and 580 mL of the second gives a mixture that is 10.24% acid, whereas blending 85 mL of the first mixed with 490mL of the second gives a 6.10% acid mixture. What are the concentrations of sulfuric acid in the original containers?
The concentrations of sulfuric acid in the original containers as per the system of equation is equals to 24% in first container and 3% in second container.
What is system of equation?" A system of equations is finite set of equations for which we find the common solution."
According to the question,
'a' represents the concentration of acid in first container
'b' represents the concentration of acid in second container
Situation1: 305 mL of the first solution and 580 mL of the second gives a mixture that is 10.24% acid, it represents the equation as,
a% of 305 + b% of 580 = 10.24% of 885
⇒ 305a + 580b = 9062.4 _______(1)
Situation 2:85 mL of the first mixed with 490mL of the second gives a 6.10% acid mixture, it represents the equation as,
a% of 85 + b% of 490 = 6.10% of 575
⇒ 85a + 490b = 3507.5 ______(2)
Solve system of equation by multiplying (1) by 85 and (2) by 305 we get,
25925a + 49300b = 770303 _______(3)
25925a + 149450b = 1069787.5 _______(4)
Subtract system of equation (3) from (4) we get,
100150b = 299483.5
⇒ b = 2.9
⇒ b≈ 3%
Substitute the value of 'b' in (2) we get,
85a + 490(3) = 3507.5
⇒85a + 1407 = 3507.5
⇒ 85a = 2037.5
⇒ a = 23.9
⇒ a ≈24%
Hence, concentration of sulfuric acid in first container 24% and second container 3% as per the system of equation.

you take away 8 and multiply and get 3a^2b^3c^5 * x^4y^3z or something
This becomes 3a^2b^3c^5x^-4y^-3z^1/8
