Part A
Answers:To find the area of the unshaded region, subtract the area of the shaded region from the sum of the areas of the rectangle and semicircle
----------------
Explanation:
When it comes to area problems, think of a grid of squares. Let's say we had a 10 by 10 grid of tiny squares (10*10 = 100 total). Now let's say 8 of them are shaded in. There are 100 - 8 = 92 unshaded squares to represent the total area of the unshaded region.
That's effectively what's going on with this problem as well. Sure things get a bit tricky with that curved portion on top, but we can still get an approximation if we use smaller and smaller grid sizes. I recommend using graph paper or graphing software that provides a grid.
========================================================
Part B
Answer: 811----------------
Explanation:
For now, I'm going to ignore the shaded region. I'll come back to it later.
The rectangle is 15 ft by 50 ft. It has an area of length*width = 15*50 = 750 sq ft.
The semicircle up top has an area of [tex]0.5*\pi r^2 = 0.5*\pi*(7.5)^2 \approx 88.3573[/tex] sq ft approximately. The 7.5 is from dividing the diameter in half to get the radius. As the instructions stated, I used the calculator's version of pi.
The rectangle and semicircle have their areas add to
750+88.3573 = 838.3573
Now we can finally address the shaded region. It is a 3 ft by 9 ft rectangle because "the length is 3 times the width" and the width is 3 ft. This shaded rectangle has area 3*9 = 27 sq ft.
The unshaded region is:
unshaded = total - shaded = 838.3573 - 27 = 811.3573
This rounds to the final answer of 811

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.

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.

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

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).

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.

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.

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.

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
