Answer:
I believe the answer is about 95 percent.
Step-by-step explanation:
The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...
22 1/5 over 100 = 21 over x
Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer
What I just wrote is the rule of proportions
Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.

You have a stack of sticky notes in six different colors. There are 600 sticky notes in the stack(100 of each color). The height is 6 cm, and the width and length are both 7.62 cm. The six colors are stacked on top of each other with the height(so each colored stack is 1cm).
1. What is the volume of each section? Describe two methods to find the volume of one of the sections.
2. What is the height of one sticky note? Describe two methods to find the height of one sticky note.

Answer:
1. 58.0644
2. 0.01
3. 14.16
Step-by-step explanation:
1. V = l*w*h
v = 7.62*7.62*1
v = 58.0644
or
v = 7.62*7.62*6
v = 348.3864
v = 348.3864/6
v = 58.0644
2. 1cm/ 100 sticky notes = 0.01
6cm/ 600 sticky notes = 0.01
3. A=2πrh+2πr2
=2·π·1.5·2×0.002+2·π·1.52
=14.15602
The volume of each section will be 58.09364[tex]cm^3[/tex]. The height of one sticky note is 0.06 cm and the surface area of one sticky note is 0.02376 sq inch.
1)The volume of one sticky note can be calculated using the formula for the volume of a rectangular prism :[tex]V = l \times w \times h[/tex], where l is the length, w is the width, and h is the height.
Length (l) = 7.62 cm
Width (w) = 7.62 cm
Height (h) = 1 cm (for each colored stack)
Substituting the values into the formula:
V = [tex]7.62 cm \times 7.62 cm \times 1 cm[/tex]
V = 58.09364[tex]cm^3[/tex].
Since there are 100 sticky notes of each color, the volume of each section can be found by multiplying the volume of one sticky note by 100:
Volume of each section =[tex]58.09364 cm^3 \times 100[/tex]
Volume of each section = 5809.364 cm³
Method 2: Using the total volume of the stack and proportions
The total volume of the stack can be calculated by multiplying the area of the base (length × width) by the total height of the stack.
Given:
Length (l) = 7.62 cm
Width (w) = 7.62 cm
Height of stack = 6 cm
Volume of stack = l × w × height of stack
Volume of stack =[tex]7.62 cm \times 7.62 cm \times 6 cm[/tex]
Volume of stack = 349.52544[tex]cm^3[/tex] (rounded to five decimal places)
Since the stack contains 600 sticky notes in total and each section represents one-sixth of the stack, we can calculate the volume of each section by dividing the total volume by 6:
Volume of each section = Volume of stack divided by 6
Volume of each section =[tex]\dfrac{349.52544 }{6} cm^3[/tex]
Volume of each section = 58.25424 cm³ (rounded to five decimal places)
The height of one sticky note, we can divide the total height of the stack by the number of sticky notes of each color.
Method 1: Direct division
The height of one sticky note can be found by dividing the total height of the stack by the number of sticky notes in each colored section.
Height of stack = 6 cm
Number of sticky notes per color = 100
Height of one sticky note = [tex]\dfrac{Height of stack } {Number\ of \ sticky \ notes \ per \ color}[/tex]
Height of one sticky note =[tex]\dfrac{6}{100}cm[/tex]
Height of one sticky note = 0.06 cm
By Using proportions, method 2 can be solved
Since each colored section represents one-sixth of the stack, the height of one sticky note can be found by multiplying the height of the stack by [tex]\dfrac{1}{6}[/tex].
Height of stack = 6 cm
Height of one sticky note =[tex]Height of stack \times\dfrac{1}{6}[/tex]
Height of one sticky note =[tex]6\times \dfrac{1}{6}[/tex]
Height of one sticky note = 1 cm
To find the surface area of one sticky note in the circular stack, we need to calculate the surface area of the cylinder and then divide it by the number of sticky notes.
Total number of sticky notes = 400
Diameter of cylinder = 3 in
Height of cylinder = 0.8 in
[tex]\pi[/tex] = 3.14
Calculate the surface area of the cylinder using the formula for the lateral surface area of a cylinder:[tex]A = 2\pi rh[/tex], where r is the radius and h is the height.
Radius (r) = [tex]\dfrac{3}{2}[/tex] = 1.5 in
Lateral Surface Area (A) = [tex]2\pi rh[/tex]
A = [tex]2 \times 3.14 \times 1.5 \times 0.8[/tex] in
A = 9.504 sq inch (rounded to three decimal places)
Since there are 400 sticky notes, we can calculate the surface area of one sticky note by dividing the total surface area by 400:
Surface area of one sticky note = [tex]\dfrac{A}{Total\ number of \ sticky \ notes}[/tex]
Surface area of one sticky note = [tex]\dfrac{9.504 }{400}sq \ inch[/tex]
Surface area of one sticky note ≈ 0.02376 sq inch.
The volume of each section will be 58.09364[tex]cm^3[/tex]. The height of one sticky note is 0.06 cm and the surface area of one sticky note is 0.02376 sq inch.

Answer:
Lou sold 5 more earings than JacobStep-by-step explanation:
Step 1
Find 20% of 200
For fraction: divide 20 by 100 and remove the % sign.
[tex]{20}\%=\frac{20}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
[tex]{20}\%=0.2[/tex]
Multiply the decimal or fraction by the quantity that equals 100%
[tex]100[/tex]%[tex]=200[/tex]
[tex]\frac{20}{100} *200=0.2*200=40[/tex]
20% of 200 is 40
Lou sold 40 rings
Step 2
Find how much more or less earings did Lou sell than Jacob

The Empire State Building is just over 1,450 feet tall. In anticipation of visiting this landmark on your vacation, you create a model of it using blocks.
a) Suppose you are making a model where one block represents 2 feet. About how many blocks tall is your model of the Empire State Building? What is the scale factor?
Answer:
365 and 1/2 blocks will be used
The scale fact is 0.25
Step-by-step explanation:
So . .
We create a ratio 1:2This represents 1 block is equivalent to 2 feet
Simply 1450 ÷ 2 = 725So . . There are 725 feet and because One block is equal to 2 feet you divide 725 ÷ 2 = 362.5 blocks will be used
To find the scale factor simply divide the deminsions of the new shape by old
362.5 ÷ 1450 = .25
