Choose one kind of triangle to use for a tessellation: equilateral, isosceles, or
scalene.
Use technology or paper to create six or more congruent copies of your
chosen triangle and investigate how the shape tessellates.
Use your chosen triangle to create an artwork with tessellations. You can use
any sizes, colors, patterns, or art mediums. You can submit a scanned copy,
photo, screenshot, or snip of your artwork.
Provide the explanation of the math behind your tessellation that the gallery
will display next to your artwork.
o

o
Use the definition of your chosen triangle and what you know about
the interior angles of triangles to prove that any version or size of that
triangle will tessellate. (Hint: Study the interior angles where the
vertices meet in the tessellation.)
Include diagrams or other visual models to help explain your proof.
Think about how you could extend your work to prove that all triangles
tessellate, and share any theories you might have.
Your completed work of art will be submitted as your portfolio assessment. It must
include your tessellation art and your explanation for the math behind it.

A stack of 500 pieces of paper is 1.875 inches tall.
Diego guesses that each piece of paper is 0.015 inches thick. Explain how you know that Diego’s answer is not correct.
Compute the thickness of each piece of paper. Show your reasoning. (upload your work when complete - no work, no credit.)
If there were 1000 sheets of paper, then the thickness of each sheet would be 1.875 in divided by 1000.
1.875/1000 = 0.001875
Since there are 500 sheets of paper, each one is twice as thick as 0.001875, so each sheet is 0.00375 inches thick. 0.015 is much greater than 0.00375, so it must be incorrect.

How many marbles are left if 9 friends equally share a package of 75 marbles?
Answer:
8 remainder 3
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 9 on the left side and the dividend 75 on the right side. step 2.The divisor (9) goes into the first digit of the dividend (7), 0 time(s). Therefore, put 0 on top Step 3:
Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend Subtract the result in the previous step from the first digit of the dividend (7 - 0 = 7) Step 5:
Move down the 2nd digit of the dividend (5)
Step 6:
The divisor (9) goes into the bottom number (75), 8 time(s). Therefore, put 8 on top
Step 7:
Multiply the divisor by the result in the previous step (9 x 8 = 72) and write that answer at the bottom
Step 8:
Subtract the result in the previous step from the number written above it. (75 - 72 = 3) and write the answer at the bottom
Kareem cannot decide which of two washing machines to buy. The seling price of
each is $520. The first is marked down by 50%. The second is marked down by 20% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the
same except for the selling price.
The sale price of the first washing machine is $
(Round to the nearest dollar as needed.)
The sale price of the second washing machine is $

A sphere has a diameter of 22 units. What are it's radius and volume?
Answer:
D. The radius is 11 units, and the volume is 5,572.45 cubic units.
Step-by-step explanation:
The radius of the sphere is 11 units and the volume of the sphere is 5572.45 cubic units.
What is a sphere?It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.
We have a diameter of the sphere = 22 units
We know the radius of the sphere is the half of the diameter.
The radius r = 22/2 = 11 units
The volume:
[tex]\rm V = \dfrac{4}{3} \pi r^3[/tex]
Plug r = 11 units and π = 3.14
[tex]\rm V = \dfrac{4}{3} \times 3.14 (11)^3[/tex]
V = 5572.45 cubic units
Thus, the radius of the sphere is 11 units and the volume of the sphere is 5572.45 cubic units.

What is the rate of change of the linear relationship modeled in the table? (4 points) x y −2 5 −1 4 0 3 1 2 a −2 b −1 c negative one over two d 1
Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: [tex]\frac{4-5}{-1-(-2)}[/tex]
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.

ANSWER NOW! A customer purchased 1/2 pound of ham, 1 pound of turkey, 1 1/2 pound of roast beef, and 1 4 pound of bologna. Approximately what will the customer pay for the purchase before sales tax?
The total amount the customer will pay is $19.46.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.
As per the given data in the question:
In the table, the cost of meat per pound is given:
ham = $5.99
turkey = $4.99
roast beef = $6.99
salami = $2.99
bologna = $3.99
The amount of meat bought by the customer is also given as:
ham = 1/2 pound
turkey = 1 pound
roast beef = 1 1/2 pound = 3/2 pound
bologna = 1/4 pound
For the total amount, the customer will pay for the purchase:
Price for the meat = cost of meat per pound × meat in pounds
= 1/2 × 5.99 + 1 × 4.99 + 3/2 × 6.99 + 1/4 × 3.99
= 2.995 + 4.99 + 10.485 + 0.9975
= $19.46
Hence, The total amount the customer will pay is $19.46.

years, OR a loan with 2% interest paid, back in 5 years? Explain.
Show work to justify your answer.
Please use good explanation
Answer:
It depends on how long it takes you to pay for it.
Step-by-step explanation:
Basically, because its lower interest, and a higher time period, then you will be paying less than if it were 5% in 2 years. HOWEVER, if you know it will be(lets say 10 years) then the amount due will be the same.
