Explain how you can use the inscribed angle theorem to justify its second corollary, that an angle inscribed in a semicircle is a right angle.

Answers

Answer 1
First, remember that an iscribed angle is an angle, call it α, made from three points on the circumference of the circle.

The inscribed angle theorem states that the  inscribed angle (α) is half of the central angle (2α).

Inscribe a triangle in a semicircle, and you will see that you will have made up the central angle 180°. So the , by the inscribed angle theorem the inscribed angle is half of 180° which is 180°/2 = 90°.

So, always the inscribed angle in a semicircles is 90° which is what a right angle is.
Answer 2

Answer:

Sample Response: A circle measures 360 degrees, so a semicircle measures 180 degrees. By using the inscribed angle theorem, the measure of the inscribed angle would be half of 180 degrees, or 90 degrees, which is a right angle.

How many times as heavy is the Golden Eagle as the Red Tailed Hawk? The Golden Eagle weighs 13 9/10 lbs and the red tailed hawk weighs 3 1/2 lbs?

Answers

In order to figure out the ration of the Golden Eagle to the Red Tailed Hawk you would need to convert their numbers a decimal. In this case you would convert 13 9/10lbs to 13.9 and 3 1/2lbs to 3.5. So now you would divide 13.9 by 3.5 and you get 3.9. So in other words you could have 3.9 Red Tailed Hawks to make one Golden Eagle. So the Golden Eagle is 3.9 times heavier than the Red Tailed Hawk.
Final answer:

The Golden Eagle, weighing 13.9 lbs, is approximately 4 times as heavy as the Red Tailed Hawk, which weighs 3.5 lbs.

Explanation:

To find out how many times as heavy the Golden Eagle is compared to the Red Tailed Hawk, we need to divide the weight of the Golden Eagle by the weight of the Red Tailed Hawk. The Golden Eagle weighs 13 9/10 lbs, which can be converted into an improper fraction as 139/10 or a decimal as 13.9 lbs. The Red Tailed Hawk weighs 3 1/2 lbs, which can be converted into an improper fraction as 7/2 or a decimal as 3.5 lbs.

To perform the division, we'll use the decimal form of the weights:

Golden Eagle: 13.9 lbsRed Tailed Hawk: 3.5 lbs

Dividing the Golden Eagle's weight by the Red Tailed Hawk's weight:

13.9 lbs ÷ 3.5 lbs = 3.9714 (approximately)

So, the Golden Eagle is approximately 4 times as heavy as the Red Tailed Hawk.

Explain why the equation 6|x| + 25 = 15 has no solution. When one solves, they arrive at a step where |x| is equal to a negative number. Since | x| can never be negative, there is no solution. When one solves, they arrive at a step where |x| is equal to a fraction that may not be represented as an integer. Since | x| must be an integer, there is no solution. When one solves, they arrive at a step where x is equal to a negative number. Since x can never be negative inside of the absolute value bars, there is no solution. The statement is false. There is a solution.

Answers

Final answer:

The equation 6|x| + 25 = 15 has no solution because it implies that |x| equals a negative number after simplification, and absolute values cannot be negative.

Explanation:

The equation 6|x| + 25 = 15 has no solution because the absolute value of x, denoted by |x|, represents the distance of x from zero on the number line, and as such, it can never be negative. When we solve the given equation, we isolate the absolute value on one side which gives us 6|x| = -10 after subtracting 25 from both sides. Dividing by 6, we obtain |x| = -10/6, which is a negative number. However, since an absolute value cannot equal a negative number, this indicates that there is no valid solution to the equation.

In this question, 10 people average running distance is 2.7miles. Then the sum of their running distance would be: 10 people * 2.7 miles/people= 27 miles.

The group then divided into 2, 4 people with 3 miles average and 6 people with unknown average. Since the people are same like the 10 people group, their total running distance would be the same. The calculation would be:

total distance = group1 * average1 + group2 * average2

an ice cream factory makes 260 quarts of ice cream in 10 hours. How many quarts could be made in 36 hours? What was that rate per day?

Answers

260 quarts * 36 hours = 9,360 quarts
260 * 20 hours = 5,200 quarts ---> 260 quarts / 10 hours = 26 quarts per hour ---> 26 quarts * 4= 104 quarts ---> 5,200 + 104 = 5,304 quarts per day

Final answer:

The ice cream factory can make 936 quarts in 36 hours and the rate per day is 624 quarts.

Explanation:

To find out how many quarts of ice cream can be made in 36 hours, we can set up a proportion based on the rate of production. The rate of production is 260 quarts of ice cream in 10 hours. We can set up the proportion:

260 quarts / 10 hours = x quarts / 36 hours

Cross-multiplying, we get:

10x = 260 * 36

Simplifying, we find:

x = (260 * 36) / 10 = 936

Therefore, 936 quarts of ice cream can be made in 36 hours.

To find the rate per day, we need to calculate how many quarts can be made in 24 hours. We can set up the proportion:

260 quarts / 10 hours = y quarts / 24 hours

Cross-multiplying, we get:

10y = 260 * 24

Simplifying, we find:

y = (260 * 24) / 10 = 624

Therefore, the rate per day is 624 quarts of ice cream.

Answer: SR is 69 units long.

------------------------------------------------------------
------------------------------------------------------------

Explanation/Work Shown:

SR is the distance from R to S (or S to R; order doesn't matter). In other words, it's the length of segment SR. In this case, SR = 7x-8 for now. Your teacher wants you to find a numeric value for SR. To do that, we need to find x first.

ST is a similar story: it's the length of segment ST. In this case, ST is the algebraic expression 3x-5. 
Finally, RT = 8x+9

So far we have these three equations:
SR = 7x-8
ST = 3x-5
RT = 8x+9

Because SR and ST combine to form RT (and because S is on line RT), this means we can say
SR + ST = RT
by the segment addition postulate

Let's plug in the equations found earlier to get...
SR + ST = RT
(7x-8) + ST = RT ... replace SR with 7x-8
(7x-8) + (3x-5) = RT ... replace ST with 3x-5
(7x-8) + (3x-5) = 8x+9 ... replace RT with 8x+9

Now let's solve for x
(7x-8) + (3x-5) = 8x+9
7x-8 + 3x-5 = 8x+9
(7x+3x)+(-8-5) = 8x+9
10x-13 = 8x+9
10x-13+13 = 8x+9+13 ... add 13 to both sides
10x = 8x+22
10x-8x = 8x+22-8x ... subtrat 8x from both sides
2x = 22
2x/2 = 22/2 ... divide both sides by 2
x = 11

Now that we know x, we can find the length of SR
SR = 7x-8
SR = 7*x-8
SR = 7*11-8 ... replace x with 11 (since x = 11)
SR = 77-8
SR = 69

Seven years ago, kodi found a box of old baseball cards in the garage. since then, he has added a consistent number of cards to the collection each year. he had 52 cards in the collection after 3 years and now has 108 cards. kodi looking into his box of baseball cards. how many cards were in the original box? is this t(0) or t(1)? write the first few terms of the sequence. kodi plans to keep the collection for a long time. how many cards will the collection contain 10 years from now? write an equation that determines the number of cards in the collection after n years. what does each number in your rule represent?

Answers

(3,52)(7,108)
slope = (108 - 52) / (7 - 3) = 56/4 = 14

y = mx + b
slope(m) = 14
(3,52)...x = 3 and y = 52
sub and find b, the y int (the original amount of cards)
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b

so ur equation is y = 14x + 10....with x being the number of years and y being the total cards. <== ur equation is y = 14x + 10

He started with 10 cards....and has been adding 14 cards every year.

so after 10 years...
y = 14(10) + 10
y = 140 + 10
y = 150 <== after 10 years, he will have 150 cards

The required equation is y = 14x + 10 which is the number of cards in the collection and he will have 150 cards after 10 years

What is the slope of the line?

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

As per the question, we take the two points are (3,52) (7,108)

So slope = (108 - 52) / (7 - 3) = 56/4 = 14

y = mx + b

slope(m) = 14

Substitute the value of x = 3 and y = 52 in the equation

52 = 3(14) + b

52 = 42 + b

52 - 42 = b

10 = b

So the original amount of cards is 10

If x represents the number of years, while y is the total number of cards.

y = 14x + 10

He began with 10 cards and has added 14 cards every year thereafter.

So after 10 years

y = 14(10) + 10

y = 140 + 10

y = 150

Therefore, he will have 150 cards after 10 years

Where the "-pi/2" part is its own fraction (x is not part of it; i.e., x is not in the numerator of the fraction). 

-------------------------------------

To find this answer, we need to ask ourselves: "1/3 times what quantity will give us (1/3)x?". The answer to this sub-question is simply x. In other words, 1/3 times x is (1/3)x. That takes care of the first part.

For the second part, we have 1/3 times something equal to -pi/6. That "something" must be -pi/2. Note how

(1/3)*(-pi/2) = (1*(-pi))/(3*2) = -pi/6

So you have to think backwards in a sense. Or you can treat it like this

(1/3)*y = -pi/6

Multiplying both sides by 3 leads to 

y = -pi/2
if you have the polynomial [tex] \frac{1}{3} [/tex] x - [tex] \frac{ \pi}{6} [/tex] by factoring out [tex] \frac{1}{3} [/tex] then the result would be:
