Answer:
12
Step-by-step explanation: this is because if the circle is 24 then half the circle should be 12 if not then I don’t know your on you own
The area of a normal full circle is given by;
[tex]a = \pi \: r {}^{2} [/tex]
but since i want a semi circle, i would want that area to be split into 2, right?
So our new equation for the area of a semi circle is given by;
[tex]a = \frac{\pi \: r {}^{2} }{2} [/tex]
where r is the radius of our semi-circle.
The radius is half the diameter, so the radius here would be 24/2 =12
[tex]a = \frac{\pi \times 12 {}^{2} }{2} = \frac{144\pi}{2} = 72\pi = 72 \times 3.14159... = 226.194[/tex]

(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)
Answer:
x = -1.5
Step-by-step explanation:
(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)
*I would first change any minus signs that are outside of the parenthesis to a plus sign. This is optional, not necessary. *
0.5x + 1.2 + (-3.6) + 4.5x = 4.8–0.3x + 10.5x + 0.6
*Now combine like terms on each side. *
5x + (-2.4) = 10.2x + 5.4
*move all Xs on one side.*
-5.2x = 7.8
*Divide both sides by -5.2 to get X by itself."
x = -1.5

Answer:
new answer with estimate= 10 old answer= [tex]9.24[/tex]
Step-by-step explanation:
Use this method percent proportion
[tex]\frac{Percent}{100} = \frac{Part}{Whole}[/tex] or [tex]\frac{Percent}{100} = \frac{is}{of}[/tex]
Answer:
12% of 77
[tex]\frac{12}{100} = \frac{x}{77} = \frac{100x}{100} = \frac{924}{100} x = 9.24[/tex]
Steps:
1. Make a proportion with the method percent proportion.
2. After setting up numbers in proportion cross-multiply.
3. Make 100x because we don't know the value of x.
4. After multiplying 12 x 77 you should've gotten 924.
5. After cross-multiplying divide your new proportion.
6. [tex]x= 9.24[/tex] estimate = 10
now I'm not sure if those number in your question is your new estimate answer but since 9.24 is close to 10 your answer will be 10

You are having a pizza - making party.
You will need 6 ounces of dough and 4 ounces of sauce for each person ( including yourself, the host ) .
Once you have a total count of guest, you buy exactly the needed amount of all the ingredients . The dough and sauce that you buy weigh 130 ounces all together.
1. How many ounces of dough did you buy?
2. How many ounces of sauce did you buy?
3. Num. Guest 0ω0
Worth 10 points . . .
Answer:
e
Step-by-step explanation:
Answer:
1. 78 ounces
2. 52 ounces
3. 12 guests
Step-by-step explanation:
1. Consider 6 ounces of dough and 4 ounces of sauce for each person as a set. So 1 set will have 10 ounces. Then, we divide the total ounces, 130 ounces by 10, which will give us 13 sets or people.Then, to find the ounces of dough,just multiply 6 ounces by 13 which will give us 78 ounces.
2. Similar to previous one, just multiply 4 ounces by 13 which will give us 52 ounces or simply minus 78 ounces from 130.
3. We obtained 13 sets(people) from number 1. Minus one (the host, yourself) from 13, we'll get 12.

Answer:
(X + 1) , (Y - 8)
Step-by-step explanation:
With this type of question, I usually like to follow one point as the others will follow the same rules. The Y coordinates of all of H'I'J'K' have been lowered drastically when compared to the original shape, so one can assume that the Y level is not increasing, especially as C would take half the points right off the grid.
By taking H's original coordinate point (in orange) we can see that it moves one forward in the X direction, or +1. Meanwhile, it moves eight down in the Y direction, or -8. Therefore, (X + 1), (Y - 8)

Each rectangle in the diagram measures 3 cm by 6 cm. What is the length, in centimetres, of the longest path from A to B? You may travel in any direction, but no segment may be traced more than once. Show your answer on the diagram below by using arrows to indicate the directions you travel.
The longest path from A to B is 36 cm.
It is given that each rectangle in the diagram measures 3 m by 6 cm.
It is required to find the longest path from A to B.
What is the area of the rectangle?It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.
The formula for finding the area of a rectangle is given by:
Area of rectangle = length × width
We have a rectangle.
Each rectangle's dimensions are 3 cm by 6 cm means:
The width of each rectangle = 3 cm
The length of each rectangle = 6 cm
In the figure, if calculate the total length of the left side that is:
= 6+6+6
=18 cm
And topside width:
=3+6+6+3
=18 cm
We can say we a rectangle having dimensions 18 by 18.
If we travel from any path the total length will be covered from A to B:
= 18 + 18
=36 cm
As per the direction, we can calculate different path distances.
Thus, the longest path from A to B is 36 cm.

Estimate both:
903.6 ÷ 25.1 =
and 760.38 ÷ 0.38
Answer:
1. 36
2. 2000
Step-by-step explanation:
Step-by-step explanation:
903.6 ÷ 25.1 = 36 (exact answer).
900 ÷ 30 = 30 (estimated). As 903.6 near to 900 and not to 1000, and 25.1 near to 30 and not to 25 the equation is 900 ÷ 30 = 30.
760.38 ÷ 0.38 = 2001 (exact answer).
In the estimated answer Im not so sure about it so I leave you four choices.
1. 800 ÷ 0.40 = 2000 (rounded to the nearest ten)
2. 800 ÷ 0.00 = Infinity (0.38 close to a whole)
3. 800 ÷ 1 = 800 (0.38 not close to a whole)
4. 800 ÷ 40 = 20 (possibly the wrong answer not even close to 0.38)

Parallel Lines and Paris of Angles
I dont understand the question please explain what i have to do and answer it thank you :)
Tell me if the image is blurry in the comment section not the answer section Thankyou
Answer:
The explanation on how to do them is down below. If you have anymore questions pls feel free to ask
Step-by-step explanation:
So for number one you just need to state the sentence under the lines back wards but starting Lines m and n......
For number two name two angles that are inside the parallel lines and for three the opposite name two that are basically verticle outside of the parallel lines.
For number four they are across from each so they are verticle and since they are verticle they are concurrent so the m of 2 is 125.
In number 5,4 and 7 are corresponding so the are equal.
In number 6 the angles are alternate interior so they are congruent.
In number 7, the angles are corresponding so they are congruent.
In number 8, the angles are alternate exterior so they are congruent.
In number 9, the angles are are verticle so the are congruent.
In number 10, the answer is supplementary because on the top and bottom they add up to 180 degrees. And it part b 2 and 3 are adjacent and supplementary, so you subtract 119 from 180 and you get 61.
18.84 cm
37.68 cm
28.26 cm
113.04 cm
Answer:
(a) 18.84 cm
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr . . . . . for radius r
A circle of radius 3 cm will have a circumference of ...
C = 2(3.14)(3 cm) = 18.84 cm
_____
Additional comment
The area is ...
A = πr² = 3.14(3 cm)² = 28.26 cm²
The units of area are not cm, but are cm². This question asks for circumference. The shading may be misleading.
Which type of line is shown in the illustration below?
A. parallel lines
B. perpendicular lines
C. skew lines
D. none of the above
Answer: B. perpendicular lines because they intersect at a right angle, making them perpendicular.
Answer:
None of the above
Step-by-step explanation:
Parallel Lines are not shown in this triangle and it is impossible for a triangle to have parallel lines due to its shape. Perpendicular lines are not shown either. Skew lines are only in 3d models and shapes. This is a 2d shape.

Answer:
well first you would need to find the lowest common denominator for both of these which would be 15 and then divide the top number by the number it takes the denominator to get to 15 which for 2/3 it would become 10/15 and 2/5 would be 6/15 and since the equation wants how much she got rid of it would be 10/15-6/16 which equals 4/15 as your answer which you might be able to simplify

Step-by-step explanation:
In 2016, a maglev train in Japan traveled 1.1 miles in 1045 seconds.
A picture of a Maglev train is shown. The caption reads Maglev trains use magnets to hover above the tracks. This helps them reach extraordinary speeds.
Question 1
Part A
Find the speed of the train in miles per hour.+
Answer: ~3.8 mph (see below)
Explanation:What we know:
We need to find the speed of the train in miles per hour (mph)The train is traveling 1.1 miles per 1045 secondsThere are 3600 seconds in 1 hourHow to solve:
We need to find what number when multiplied with 1045, will equal 3600. The unknown will be a variable x, and the seconds will be represented with s. Then, we need to multiply this number with the value of the miles (m) to find how many miles are traveled in that hour (h).
Process:Finding X (in seconds)
Set up equation H = sx
Substitute 3600 = 1045x
Divide /1045 /1045
Solution 3.44497608 = x
Finding Miles
Set up equation mph = x(m/s)
Substitute mph = 3.44497608(1.1/1045)
Simplify mph = ~3.79/3600
Convert mph = ~3.8 miles per hour
Solution: ~3.8 mph (3.78947369 miles per 3600 seconds)

Answer:
Question 1: y = x + 4 if x>5
Question 2: y = x
Question 3: y = -x-4
Question 4: y = 3x-6
Step-by-step explanation:
Ok, I will admit, these questions are a bit confusing, but I will try my best.
Question 1: y = |x-3| + |x+2| - |x-5| if x>5. So, let's plug in a number greater than 5 - 6. y = |6-3| + |6+2| - |6-5|. Inside the absolute value, every number is positive, which pretty much renders the absolute value symbol useless. So, you can take the equation and change the absolute value lines into parentheses. y = (x-3) + (x+2) - (x-5). In order to get rid of the parentheses, you have to distribute any subtraction symbols which is in front of x-5. This makes our equation y = x - 3 + x + 2 -x + 5. Combine like terms to get y = x + 4 if x>5.
Question 2: y = |x-3| + |x+2| - |x-5| if -2<x<3. Let's plug in a number between -2 and 3 so 0. y = |0-3| + |0+2| - |0-5|. x-3 becomes a negative number, x+2 becomes a positive number, and x-5 becomes a negative number. Just like question 1, we can leave the x+2 alone since it's a positive number, but we have to change the x-3 and the x-5. So we'll take the equation and change the absolute value to parentheses, but for the values that are negative, we have to put a negative sign in front of to make it positive. Our equation looks like y = -(x-3) + (x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. We distribute the negative to x-3 to make our equation y = -x+3 + x+2 + x-5. Combine like terms to get y = x
Question 3: y = |x-3| + |x+2| - |x-5| if x<-2. Let's plug in -3 since it's less than -2. y = |-3-3| + |-3+2| - |-3-5|. All three parts of the function are negative numbers, so when we change it to parentheses, all parts will have a negative to distribute. Our equation looks like y = -(x-3) -(x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. We distribute the negative to x-3 and x+2 to make our equation y = -x+3 + -x-2 + x-5. Combine like terms to get y = -x-4.
Question 4: y = |x-3| + |x+2| - |x-5| if 3<x<5. Let's plug in 4 since it's in between 3 and 5. y = |4-3| + |4+2| - |4-5|. Only x-5 is negative so that's the only one we need to put a negative in front of when we change it to parentheses. Our equation looks like y = (x-3) + (x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. Our equation is now y = x-3 + x+2 + x-5. Combine like terms to get y = 3x-6.
Hope this helps! :)
