Answers
Answer:
A. 108 in^2
B. 144 in^2
C. 36 in^2
Step-by-step explanation:
Triangle pyramid:
4 times the area of the triangle, since they are equal. We know that the height is 9 inches and that the base is 6 inches, so the area of the triangle is the multiplication of the base times the height divided by two. Then:
At = b*h/2
At = 6*9/2
At = 27
27 square inches would be the area of one single triangle, but since there are 4 it would be 4*27=108 square inches.
For a triangular-based pyramid it would take 108 square inches of paper.
Square- pyramid:
It would be 4 times the area of the triangle, since we assume that they are equal. Adding the base of the pyramid, that would be the area of a square. The area of the square is equal to the base times the base or base to the square.
In other words, the total area above would be 108 square inches adding the area of the square. So
As=b*b
Ace=6*6
Ace=36
Therefore the final area would be 108+36=144 square inches.
For a Quadratic pyramid it would take 144 square inches of paper.
The difference between one and the other is 36 square inches, which is equivalent to the square base of the square pyramid.

Step-by-step explanation:

To find the decimal of 9/25, Tyler reasoned: “9/25 is equivalent to 18/50 and to 36/100, so the decimal of 9/25 is 0.36.”
Use long division to show that Tyler is correct.
Is the decimal of 18/50 also 0.36? Use long division to support your answer.
If its not too much can I have a explanation
Answers
Answer:
18/50 is also 0.36
Step-by-step explanation:
9/25, 18/50, and 36/100 are all the same number. They are just in different forms. 9/25 is the simplest form of 18/50 and 36/100. If you divide 36/100 by 9/25, you will get 4/4, which is 1, meaning that they are the same number. Same thing with 18/50. 18/50 divided by 9/25 is 2/2, which is 1, proving all of these numbers congruent.
Is the sum of 1/2 and 2/5 greater than 1?
Is the sum of 4/5 and 1/10 closer to 1/2 than to 1?
Answers
Answer:
no for both
Step-by-step explanation:
1/2 + 2/5=9/10
4/5 + 1/10= 9/10
Answer:
The first questions answer is No, because 1/2 converted to a fith is 2.5, so 2 fiths +2.5 fiths is 4.5 fiths vs 1 whole.
And to the second question the sum of 4/5 and 1/10 is closer to 1 than 1/2 because 1/10 + 8/10 ( which i turned 4/5 into a tenth) is 9/10 which is closer to One than 1/2

A is true, see why below
B is true, see why below
C is false, see why below
D is true, see why below
Step-by-step explanation:
A is true because it is adjacent and they are both supplementary to each other, so the sum of them both would lead to 180
B is true because it is vertical to 7, which also means it is the same as 7.
C is false because those angles are not complimentary, therefore they will not add up to 90.
D is true because 4 and 5 are adjacent, they are also supplementary, therefore the sum of 4 and 5 = 180.

If on a scatter plot, there is a cluster of points that follow a certain trend, and one lone point far away that also follows that trend, is that lone point an outlier?
Answers
Answer:
yes!
Step-by-step explanation:
The point away from the cluster would be an outlier because it is away from the points that are together and it is just not a part of them so it would be an outlier.
HOPE THIS HELPED
Answer: Since most of the clustering algorithms have a minimum threshold of data points to form a cluster, the outliers are the lone data points that are not clustered.

Answers
Answer:
Part A: 18
Part B: Missing information
Part C: 1.62 Missing information
Step-by-step explanation:
For part A, you have to multiply 1/4 x 72 because 72 is how many servings of one box, and 1/4 is the amount needed to make 1 serving, which is 1/4 cups.
For Part B, I sadly can not answer because the table is needed to solve it, and was not included
For Part C, 1/4 of 6.48 could help us because it can give us the amount needed to cost to buy enough mix for one serving but not how many biscuits. So it's less than 1.62

Answer:
Figure A, C, and D
Step-by-step explanation:
Reflection is the mirror image of a shape. Every point in a figure is at equidistant from each corresponding point in another figure from the line of reflection.
Answer:
You can create figure A′ by flipping figure A over its leftmost side. So A and A′ are reflections of each other.
You cannot create figure B′ by flipping figure B over any of its sides. So B and B′ are not reflections of each other.
You can create figure C′ by flipping figure C over its rightmost side. So C and C′ are reflections of each other.
You can create figure D′ by flipping figure D over its leftmost side. So D and D′ are reflections of each other.
You cannot create figure E′ by flipping figure E over any of its sides. So E and E′ are not reflections of each other.
You cannot create figure F′ by flipping figure F over any of its sides. So F and F′ are not reflections of each other.

Diagrams A and B are scale drawing of the same field. Each square is 1 centimeter long. If the scale of diagram A is 1 cm : 24 ft , what is the scale of diagram B?
Answers
Answer:
[tex]6cm:12cm[/tex]
Step-by-step explanation:
Okay so remember this you need to know model: actual. This is really, important to know when solving.
Model: Model dimensions Example: 1cm
Actual: Actual dimensions Example: 24ft
Graph A:
1. Count the boxes. remember that each box is 1cm. After you counted all sides of the graph you should've gotten 12cm by 6cm.
2. After you got your model dimensions your goal is to find the ACTUAL dimensions. By finding the actual dimensions Multiply 12(24) and 6(24) Note: you need to multiply your actual from your scale. Times your dimensions for each side.
3. After multiplying you should've got 288ft by 144ft this is your actual dimension for graph A.
Graph B:
1. Now your answer the problem is asking for also has to do with graph A. In order to do this process, you need to divide each dimension by width and length. [tex]\frac{288}{24}[/tex] this is your length [tex]\frac{144}{24}[/tex] this is your width. divide
2. you should've gotten 12 and 6. now make your numbers into a scale

88/27
Step-by-step explanation:
Convert (2+(2/3)) into a improper fraction. To do this multiply the denominator (3) by the whole number (2) and add the numerator (2). (3*2)+2 = 8. Then put 8 over a denominator which is equal to the denominator of the mixed fraction. So (2+ (2/3) is 8/3) Do the same process with the other fraction.
Then multiply the numerators and denominators of the improper fractions:
(8/3)*(11/9) gives (88/27).

Circle A has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. The diameter of circle B is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle.
Part B: Use the formula for area and solve for the value of pi for each circle.
Part C: What observation can you make about the value of pi for circles A and B?
Answers
Answer:
A. The circumference is (pi)d where d is the diameter. So (pi) for circle A is 21.98/7=3.14 and for B is 18.84/6=3.14.
B. Area is (pi)r^2 where r=radius or d/2. So for circle A (pi)=38.465/(3.5)^2=3.14 and circle B (pi)=28.26/(3)^2=3.14.
C. To two places of decimals (pi) has a value of 3.14 in all cases. This indicates or implies that (pi) is a universal constant applying to all circles using the formulae.
