Find the expression that does NOT answer the question: "What fraction of 8 is 2 1/2?"
A. 2 1/2 divided by 8
B. 5/2 x 1/8
C. 8 divided 2 1/2
D. ? x 8 = 2 1/2
Option B is the expression that does NOT answer the question.
What is an equivalent expression?An equivalent expression is an expression that has the same value but does not look the same. When you simplify an expression, you're basically trying to write it in the simplest way possible.
For the given situation,
Let the unknown number be x or 1/x
Option A) 2 1/2 divided by 8
If unknown number is x,
then, 8x = 2 1/2
⇒ x = 2 1/2 ÷ 8
So, option A is correct.
Option B) 5/2 x 1/8
⇒ [tex]\frac{(5)(1)}{(2)(8)}[/tex]
⇒ 5/16
So, option B is incorrect.
Option C) 8 divided 2 1/2
If unknown number is 1/x,
then, 8/x = 2 1/2
⇒ x = 8 ÷ 2 1/2
So, option C is correct.
Option D) ? x 8 = 2 1/2
If fraction is not known, it can be replaced by '?'
So, option D is correct.
Hence we can conclude that option B is the expression that does NOT answer the question.

Please help me!!! WITH MATH
30 points for this and brainliest!
Answer all question and don't steal the points or i will report.
Answer:
1. I think A is 5 because it is the lower quartile range
2. The median of the data is 56 because the median of a plot is in the middle of the data
3. The greatest value of the data plot is 45 because it is higher than the rest of the numbers (upper quartile range).
4. The median of the plot is 41 because if you look at the box-whisker plot you can see that it is in the middle of the box
5. Your answer would be 42 because on a box-whisker plot, the first quartile is on the side of the box(first quartile).

Step-by-step explanation:
an iron cube measures 10cm by 10cm by10cm. what is its volume? if the same iron cube weights 7.9 kg, what is its density in g/cm?
The volume of the iron cube is 1000 cm³ and its density is 7.9 g/cm³.
Explanation:1. Volume of the iron cube:
The volume of a cube is calculated by multiplying the length, width, and height. In this case, all three sides are 10cm, so the volume is:
Volume = 10 cm × 10 cm × 10 cm = 1000 cm³
Therefore, the volume of the iron cube is 1000 cubic centimeters.
2. Density of the iron cube:
Density is defined as mass divided by volume. We know the volume from the previous calculation and the mass is given as 7.9 kg.
However, we need to convert the mass to grams because the volume is in cubic centimeters. There are 1000 grams in 1 kg, so:
Mass in grams = 7.9 kg × 1000 g/kg = 7900 g
Now, we can calculate the density:
Density = Mass / Volume = 7900 g / 1000 cm³ = 7.9 g/cm³
Therefore, the density of the iron cube is 7.9 grams per cubic centimeter.

Bert already has $50 but needs a total of at least $250 for his holiday. He gets paid £20 day for delivering papers. What is the least number of days he must work to get enough money for his holiday?
Answer: Hi!
We know that Bert has $50, but he needs a total of at least $250 for this holiday. The differences between what he needs and what he has is:
$250 - $50 = $200
So he needs another $200.
He gets paid £20 a day and we want to know the number of days that he needs to work in order to obtain the $200.
The first step is to transform the £20 into dollars.
£1 = $1.27
then his daily pay in dollars is: 20*$1.27 = $25.4
Now let's call X the number of days that he needs to work to obtain the $200, we got:
X*$25.4 = $200
X = $200/$25.4 = 7.8
We should round up this result because we want a whole number.
X = 8, this means that Bert needs to work at least 8 days if he wants to have at least $250 for the holidays.

Which equation BEST represents the line of best fit for the scatterplot? A) y = x + 2 B) y = x + 1 C) y = x - 2 D) y = 2x + 1
Answer:
y=x+2 is the right answer
Step-by-step explanation:
Equation A best represents the line of best fit for the scatter plot. Option A is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
From option 1;
y= x+2
At,x=0 y=2
At,y=0 x=-2
The equation satisfy the graph in the best possible way. So that equation A best represents the line of best fit for the scatter plot.
Hence, option A is correct.

From our diagram we can see that angle HED equals to angel GED and angle GDE equals to angel HDE.
Two triangles are similar if the corresponding angles are equal, so their corresponding sides will be in equal ratio.
Upon setting ratios of corresponding sides of our triangle equal we will get,
[tex]\frac{EG}{GD} =\frac{EH}{HD}[/tex]
[tex]\frac{99.2}{62} =\frac{112}{(x+2)}[/tex]
Now we will use cross multiplication to solve our equation,
[tex]99.2(x+2)=112\cdot 62[/tex]
[tex]99.2x+198.4=6944[/tex]
[tex]99.2x=6944-198.4[/tex]
[tex]99.2x=6745.6[/tex]

Is 96 fl. Oz greater or less than 13 c
96 fluid ounces is less than 13 cups.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
To compare 96 fluid ounces and 13 cups, we need to convert one of the quantities so that they are in the same units.
One cup is equal to 8 fluid ounces.
So,
13 cups is equal to:
13 cups x 8 fluid ounces/cup
= 104 fluid ounces
Now,
We can compare 96 fluid ounces and 104 fluid ounces.
Since 104 is greater than 96.
Thus,
96 fluid ounces is less than 13 cups.
