The formula for arc length is s = r(theta) Theta must be in radians, so convert 40 degrees to radians, which is 2pi/9. Multiply 2pi/9 by the radius, 9, and then you'll get the answer. Hopes this helps!
Answer:
B. 6.3 cm
Step by step explanation:
We have been given measure of central angle which intercepts to our minor arc XY.
Since we know that the formula to find measure of arc length is:
[tex]\text{Arc length}=\frac{\theta}{360}\times \text{circumference of circle}[/tex]
[tex]\text{Arc length}=\frac{\theta}{360}\times {2\pi r}[/tex]
Now let us substitute our given values in above formula.
[tex]\theta=40^{o}[/tex] and [tex]radius=9 cm[/tex]
[tex]\text{Arc length}=\frac{40}{360}\times {2\pi \cdot 9}[/tex]
[tex]\text{Arc length}=\frac{1}{9}\times {2\pi \cdot 9}[/tex]
[tex]\text{Arc length}=2 \pi [/tex]
[tex]\text{Arc length}=6.2831853071795865\approx 6.3[/tex]
Therefore, length of minor arc XY is 6.3 cm and option B is the correct choice.

A right triangle has sides measuring 5 inches, 12 inches, and 13 inches. What is the area, in square inches, of this triangle ?
Answers
a + b + c
s = -------------------
2
Then calculate A:
A = sqrt[ s(s-a)(s-b)(s-c) ]
Final answer:
The area of a right triangle with sides of 5 inches and 12 inches as the base and height, respectively, is 30 square inches, calculated using the formula A = (base × height) / 2.
Explanation:
The area of a right triangle is calculated by multiplying one-half the base by the height: A = (base × height) / 2.
In the case of a right triangle with sides measuring 5 inches, 12 inches, and 13 inches, the 5-inch and the 12-inch sides are the legs and thus can be used as the base and height. Using the formula for the area of a right triangle:
A = (5 × 12) / 2
A = 60 / 2
A = 30 square inches
Therefore, the area of this triangle is 30 square inches.

An ellipse has a center at the origin, a vertex along the major axis at (0, 17), and a focus at (0, −8). Which equation represents this ellipse?
Answers
Since the focus and vertex are above and below each other, rather than side by side, I know that this ellipse must be taller than it is wide.
Then
a² will go with the y part of the equation
Also, since the focus is 8 units below the center, then c = 8
since the vertex is 17 units above, then a = 17
The equation b² = a² – c² gives me
b²=17²-8²-----> b²=225
the equation is
y²/a²+x²/b²=1------> y²/289+x²/225=1
the answer is
y²/289+x²/225=1

{(1, 3), (2, 5), (3, 8), (4, 10)}
{(4, 6), (5, 9), (4, 7)}
{(0, 2), (0, 3), (1, 5), (4, 5)}
Answers
B. This is a function. All of the x values are different. The points, when graphed, pass the vertical line test. In other words, its impossible to draw a vertical line through any two points on the graph. Any x input here leads to exactly one y output.
C. This is not a function. Like choice A, we have repeated x values. In this case we have (4,6) and (4,7). The x value x = 4 repeats itself leading to multiple outputs y = 6 and y = 7
D. This is also not a function. The x value x = 0 repeats itself. The graph fails the vertical line test.

What happens to people who don’t know toothpaste from putty?
Answers
Final answer:
Toothpaste is designed specifically for oral hygiene and contains abrasives and fluoride, unlike putty. Recognizing and using toothpaste instead of incorrect substances like putty is crucial for maintaining dental health.
Explanation:
When a person does not know how to distinguish between toothpaste and putty, they may lack basic knowledge about oral hygiene and the purpose of toothpaste. Toothpaste is formulated to clean and maintain the health of teeth; it usually contains abrasives that scrub the teeth and fluoride that helps prevent cavities.
It is essential to use toothpaste rather than any other substance, such as putty, which does not provide the same benefits and can be harmful if ingested. Learning to recognize and use toothpaste correctly is part of basic health awareness and contributes to overall wellbeing.
Find the equation of the line whose x-intercept is 8 and y-intercept is -2. write the equation in slope-intercept form.
Answers
0-(-2)
m = ---------- = 1/4
8-0
The equation of the line is then y-0 = (1/4)(x-8), or y = (1/4)X - 2 (in slope-intercept form).
To determine the equation of the line with x-intercept 8 and y-intercept -2, the slope is calculated to be 1/4. Thus, the line's equation in slope-intercept form is y = (1/4)x - 2.
To find the equation of a line with an x-intercept of 8 and a y-intercept of -2, we'll first determine the slope of the line (m) and then use the slope-intercept form (y = mx + b).
Two points on this line are (8,0) and (0,-2). The slope (m) of a line is calculated by the change in y divided by the change in x, which in this case is
(0 - (-2)) / (8 - 0) = 2 / 8 = 1 / 4.
Now we know the slope is 1/4 and the y-intercept (b) is -2, so the equation of the line in slope-intercept form is:
y = (1/4)x - 2

One hundred employees of a company are asked how they get to work and whether they work full time or part time. The table below shows the results. If one of the 100 employees is randomly selected, find the probability of getting someone who carpools or someone who works full time.
Full time Part time
Public Transportation 7 10
Bicycle 4 3
Drive alone 30 31
Carpool 6 9
Answers
These events are not mutually exclusive, meaning they can happen at the same time. This means we use
P(A or B) = P(A) + P(B) - P(A and B)
P(carpool or full time) = P(carpool) + P(full time) - P(carpool & full time)
There are 6+9=15 people out of 100 that carpool.
There are 7+4+30+6=47 people out of 100 that work full time.
There are 6 people out of 100 that carpool and work full time.
This gives us
15/100 + 47/100 - 6/100 = 56/100
The probability of getting someone who carpools or someone who works full time is 0.36.
Explanation:To find the probability of getting someone who carpools or someone who works full time, we need to add the probabilities of the two events.
The probability of getting someone who carpools is 6/100 and the probability of getting someone who works full time is 30/100.
So the probability of either event happening is (6/100) + (30/100) = 36/100 = 0.36.

In how many ways can the letters of the word BANANA be rearranged such that the new word does not begin with a B?
Answers
First arrange the words in order:
AAABNN
so there are 3 A's, 1 B and 2 N's.
If there were no constraints,
Number of permutations = (3+1+2)!/(3!1!2!)=6!/(6*1*2)=720/(6*2)=60
Number of words that begin with B is to take out the B, that leaves us with
AAANN => 3 A's and 2 N's
=> 5!/(3!2!) = 120/(6*2)=10
Therefore the number of words that do NOT begin with B is

Adult pinball machine GAME with base ME measuring 35 inches and sides measuring 56 inches. Child pinball machine G prime A prime M prime E prime with base M prime E prime measuring 14 inches
If the perimeter of the adult pinball machine is 167 inches, what is the length, in inches of Segment line G prime A prime? Type the numeric answer only in the box below.
Answers
first of all you need to find the missing length on the adult version.
so the work would be:
-add up all the known sides of adult so
(56+56+35)=147
-then take the total perimeter and subtract so
167-147=20
-then you need to compare the two known sides of both the adult and kids version. so that would be the bottom line EM.
They are 35 and 14 so divide
35/14=2.5
Now you know the dilation so you can figure out the missing side GA on the childs by taking the missing side from the adult dividing by the dilation 2.5 to get the answer so
20/2.5= 8
the answer is 8.

Please answer will give brainliest
Answers
x-------> Orville speed
y-------> Randy speed
t--------> Randy time
we know that
speed=distance /time
Orville traveled at a speed that was twice as fast as randy
so
x=2y------> equation 1
speed Orville
x=240/(t-1)------> equation 2
speed Randy
y=150/t------> equation 3
substitute equation 1 in equation 2
2y=240/(t-1)------> y=120/(t-1)----------> equation 4
equate equation 3 and equation 4
150/t=120/(t-1)------> 150*(t-1)=120*t----> 150*t-120*t=150
30*t=150-----> t=5 hours
Orville speed and time
x=240/(t-1)-----> 240/(4)----> 60 miles/hour
Orville speed is 60 miles/hour
Orville time is (t-1)----> 5-1-----> 4 hour
Randy speed and time
y=150/t-----> 150/5----> 30 miles/hour
Randy speed is 30 miles/hour
Randy time is t-----> 5 hours
the answers are
a) Orville speed is 60 miles/hour
b) Orville time is 4 hours
c) Randy speed is 30 miles/hour
