into the jar shown. About how much jelly will he
need to fill the jar to 0.5 inch from the top? Circle
the correct answer. (Use 3.14 for T, and round to the
nearest whole.)
Answer:b
Step-by-step explanation:
Option B will be the correct option.
Given in the question,
Radius of the cylindrical jar = 2 inchesHeight of the jar = 5 in.Height of the jelly in the jar = (5 - 0.5) = 4.5 inchesExpression for the volume of a cylinder = [tex]\pi r^{2}h[/tex]
= [tex]\pi (2)^2(4.5)[/tex]
= [tex]18\pi[/tex]
= 18(3.14)
= 56.52
≈ 57 in³
Therefore, Option B is the correct option.
Isabelle calculated the volume of whole jar that is 63 in³ by using the same expression.
Hence, she chose Option C as the correct option.

What is the Inequality for this graph?
Given:
The graph of an inequality.
To find:
The inequality for the given graph.
Solution:
From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-0=\dfrac{-4-0}{0-6}(x-6)[/tex]
[tex]y=\dfrac{-4}{-6}(x-6)[/tex]
[tex]y=\dfrac{2}{3}(x-6)[/tex]
[tex]y=\dfrac{2}{3}x-4[/tex]
The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.
[tex]y<\dfrac{2}{3}x-4[/tex]
Therefore, the required inequality for the given graph is [tex]y<\dfrac{2}{3}x-4[/tex].
Roxana tiene que responder la siguiente consigna que le dio la seño ``si para dividir un numero por 10 le debo suprimir a ese numero la ultima sifra como por ejemplo 120÷10 =12 0 122÷10 =12 y me sobran 2 ¿como harias para dividir un numero decimal como 0,1 en 10 ?
Answer:
Para dividir un número decimal como 0.1 en 10 se debe adicionar un 0 del lado derecho del punto, es decir, del lado de los decimales.
Step-by-step explanation:
Dado que, si para dividir un número por 10 le debo suprimir a ese número la última cifra, como por ejemplo 120/10 es igual a 12, o 122/10 es igual 12 y me sobran 2, para dividir un número decimal como 0.1 en 10 se debe adicionar un 0 del lado derecho del punto, es decir, del lado de los decimales. Esto se comprueba al realizar dicha división:
0.1 / 10 = 0.01
0.01 / 10 = 0.001
Find the slope of the line that passes through (4,-2) and (2,4) please
Answer: -3
Step-by-step explanation:
To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.
if the mean of 4,6,4,7,(x+1),8 and 2 is 5 ,find the median
===========================================================
Explanation:
The mean is found by adding up all of the values and dividing by n, where n is the number of values in the set.
In this case, we have n = 7 values here. We count (x+1) as well since x is a placeholder for a number, which makes (x+1) also a placeholder in a sense.
As for what replaces x, we're not sure yet but we can use algebra to solve.
Lets add up all of the values given except for the "5" at the end. That 5 is the mean which is not part of the data set.
Adding up those values mentioned gives:
4+6+4+7+(x+1)+8+2 = x+32
Then divide this over n = 7 to get the mean 5
(x+32)/n = mean
(x+32)/7 = 5
-----------------------------
Let's isolate x
(x+32)/7 = 5
x+32 = 7*5
x+32 = 35
x = 35-32
x = 3
If x = 3, then x+1 = 3+1 = 4
So the (x+1) is being a placeholder for the number 4.
In other words, we'll replace the (x+1) with 4.
The data set of
4,6,4,7,(x+1),8,2
updates to
4,6,4,7,4,8,2
-----------------------------
We'll get to the median in a moment, but first we need to check if we have the correct replacement for (x+1)
Add up the values in the set {4,6,4,7,4,8,2}
Doing so leads to: 4+6+4+7+4+8+2 = 35
Then divide by n = 7 to compute the mean: 35/n = 35/7 = 5
We get the mean is 5 which matches with the instructions. So we have the correct replacement for the (x+1). We can now find the median.
------------------------------
To find the median of any data set, we need to make sure the numbers are in order from smallest to largest.
Right now {4,6,4,7,4,8,2} is not sorted, but we can sort the items to get {2,4,4,4,6,7,8}
The median is at the exact middle. In this set, the median is that third copy of '4'. Note how "2,4,4" is to the left of the median while "6,7,8" is to the right of the median. There is the same number of values on either side of the median to show things are balanced and we are at the center point.
As an alternative, you can cross off each pair of outer values one at a time until you steadily arrive at the midpoint, which again is that third copy of '4'.
So that's why the median is 4.

Carpet for one office costs $210. If the carpet sells for $8.75 per
square yard, how many square yards of carpet are needed for
one office?
Answer:
a.
Let x be the number of square yards of carpeting for which the total cost charged by the two companies will be the same.
We have an expression for the total cost of Country Carpets:
($22/ 1 yd^2)* (x yd^2) + $100
= $22*x+ $100
or 22x+ 100
We also have another expression for the total cost of City Carpets:
($25/ 1 yd^2)* (x yd^2)+ $70
= $25*x+ $70
or 25x+ 70
Now set the two expressions to be equal:
22x+ 100= 25x+ 70
⇒ 100- 70= 25x -22x
⇒ 30= 3x
⇒ 30/3= x
⇒ 10= x
The final answer for a is 10 square yards of carpeting~
b.
Let's assume that Mr. Shu wants to install carpeting for 1 square yard.
Country Carpets: $22*1+ $100= $122
City Carpets: $25*1+ $70= $95
Therefore, Mr. Shu will be likely to choose City Carpets if he wants to install carpeting for 1 square yard.
Now let's try x=11 (square yard):
Country Carpets= $22*11+ $100= $342
City Carpets= $25*11+ $70= $345
Therefore, Mr. Shu will be likely to choose Country Carpets if he wants to install carpeting for 11 square yard.
If you paid really close attention, you would notice that the price of City Carpets will be cheaper than the other when x is >0 and <10. At x=10, the price is equal. When x is >10, the price of Country Carpets will be cheaper than the other one.
So it depends:
If x were >0 and <10, Mr. Shu would be likely to choose City Carpets.
If x were 10, Mr. Shu could choose either Country Carpets or City Carpets.
If x were > 10, Mr. Shu would be likely to choose Country Carpets.
Hope this helps~

Step-by-step explanation:
In an ice cream shop there is some money in a drawer. After 6 ice creams were sold, there were 70 euros left in the drawer. After a total of 16 ice creams were sold, there were 120 euros left in the drawer. How many euros were there in the drawer at the start?
Answer: There were 40 euros in the drawer at the beginning.
Step-by-step explanation:
When we subtract 6 from 16, we get 10 more ice-creams were sold.
Similarly, we subtract 70 from 120, we get 50 euros was the total selling price of 10 ice-creams.
i.e. Selling price of 1 ice-cream = (50)÷10 =5 euros
Selling price of 6 ice-creams = 6 x 5 = 30 euros
Money in the drawer at the beginning = 70-30 = 40 euros
Hence, there were 40 euros in the drawer at the beginning.

Find the the area of a right triangle if 8cm and 12cm are a leg and a hypotenuse. Round to the nearest hundredth.
Answer:
Step-by-step explanation:
The area of a triangle is
A=bh/2 where b=base and h=height. So we first have to solve for h
8^2+h^2=12^2
h^2=12^2-8^2
h^2=144-64
h^2=80
h=(80)^(1/2), now we can find the area
A=8(80^(1/2))/2
A=4(80^(1/2)
A=35.78cm

Now to find <x, we can use the exterior angles theorem a couple of times.
<x=<p+<AGE
<x=30 degrees + <AGE
Now use the theorem again to find <AGE
<AGE=<q+<BIG
Now use substitution for <q and for <AGE
<x=30 degrees+60 degrees+ <BIG
We put this to the side for now and try solve for <CHD which is not very difficult
<CHD=180-45-20=115
We can also clearly figure out <HFI using vertical angles theorem.
<HFI=<Y
Because they all form a triangle we can conclude that <y+<BIG=180 degrees-<FHI= 180-115=65 degrees
substitution again
<x+<y=30+60+<BIG+<HFI (remember <HFI = <y vertical angles theorem)
<x+<y=30+60+65 (remember how we did before these 2 angles adds up to 65?)
<x+<y=155 degrees
Now please don't hate me on this, I'm sure there is more efficient ways to explain this problem, this is just my way from trial and error.
