67°, every triangle equals 180° so add together 35+78 which equals 113. subtract 180-113 and get 67!

Let another angle be x

According to angle sum property

Convert the mixed numbers to improper fractions, then find the LCD and combine.

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.

A large box of biscuit mix costs $6.48. The box contains 72 servings of biscuit mix. One serving is equal to ¼ cup of biscuit mix. This table shows the amount of mix and water needed to make different numbers of biscuits.

Part B
What is the total number of biscuits that can be made using one box of the biscuit mix? Show your work or explain your answer.



Part C
What is the cost, in dollars and/or cents, per biscuit? Show your work or explain your answer.

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

Hope this helps a bit.

Step-by-step explanation:

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.

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.

The answer is 3 4/12.

Answer:

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).

1/2 + 2/5=9/10

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

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

Six pairs of figures are marked in the tessellation. Identify which of these pairs of figures are reflections of each other.

Answers

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.

Answer:

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.
