The big arc is 2.09 centimeters longer than the small arc.
How much longer is the big arc than the small arc?For a circle of radius R, if we define an arc with an angle θ, the length of that arc will be:
L = (θ/360°)*2πR
Where π = 3.14
in this case, for both arcs, we have θ = 120°.
For the smaller arc, the radius is R = 5cm, so we get:
L = (120°/360°)*2*3.14*5cm = 10.47 cm
For the larger arc, the radius is R = 5cm, so we get:
L' = (120°/360°)*2*3.14*6cm = 12.56 cm
Then we can see that:
L' - L = 12.56 cm - 10.47 cm = 2.09 cm
So the largest arc is 2.09 centimeters longer than the smaller arc.

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 31 feet up. The ladder makes an angle of 78
with the ground. Find the length of the ladder. Round your answer to the nearest tenth of a foot if necessary.
Answer:
30.7 ft ladder length
Step-by-step explanation:
The ladder makes the hypotenuse of a right triangle
31 feet is the opposite leg of 78 degree angle
sin 78 = opposite / hypotenuse
sin 78 = 30/ hypot
30 / (sin 78 ) = hypotenuse = 30.7 ft
Answer:31.7

Find the measure of the angle indicated
Answer:
59°
Step-by-step explanation:
Well, as you can see from the figure, the line WU is a diameter which means that it is a straight line. So, Angle WSU is 180° (Because straight angles are 180°)
Also, angle WSU is formed by addition of angle VSW and VSU. The value of VSU is given in the picture. So,
∠VSW + ∠VSU = 180°
∠VSW = 180° - ∠VSU
∠VSW = 180° - 121 (Because ∠VSU is given 121°)
∠VSW = 59°
Therefore, angle VSW is 59 degrees.
So, here you go. I hope you understand my explanation. Have a good day.

Answer:
The first one is Perimeter The second one is Area The third on is Volume.
Step-by-step explanation:
A box big enough to hold a computer is the area of something, A fence to go around the garden would be the perimeter, enough carpet to cover the floor is the volume
A fence to around a flower garden ---> perimeter
A box big enough to hold a computer ---> volume
Enough carpet to cover the floor ---> area
What is perimeter?Distance around the outside of a shape.
What is volume?The number of cubic units that make up a solid figure; the amount of space the figure occupies. In Cubic Units, or units³.
What is area?The space or surface enclosed in 2-dimensional shape.
Using these definitions, it can be said that the fence acts as a perimeter surrounding a flower garden. Each side has a length.
A box big enough enough to hold a computer is the amount of space in the box to make it big enough to hold the computer (The volume of the box).
The amount of carpet to cover the floor is acting as a 2-dimensional shape scenario as the carpet is likely a standard typical shape such as a rectangle or square. Overall, enough to occupy a standard-sized room.

3 races
6 races
9 races
37 races
Answer:

Step-by-step explanation:
If he won 40% of the races he competed in, and he raced 15 times, this means that he won roughly 4/10 races.
4/10= ?/15
cross multiply 4 and 15 = 60

Answer:
As ΔABC is an isosceles triangle:
⇒ BA = BC
(the dashes on the line segments indicate they are of equal measure)
⇒ ∠BAC = ∠BCA = 55°
⇒ ∠BCA = ∠BAD = 55°
Angles on a straight line sum to 180°
⇒ ∠ADE + ∠EDC = 180°
⇒ 98° + ∠EDC = 180°
⇒ ∠EDC = 82°
As BE intersects AC, the vertically opposite angles are equal:
⇒ ∠BDC = ∠ADE = 98°
⇒ ∠ADB = ∠EDC = 82°
Interior angles in a triangle sum to 180°
⇒ ∠BAD + ∠ADB + ∠ABD = 180°
⇒ 55° + 82° + ∠ABD= 180°
⇒ ∠ABD = 180° - 55° - 82°
⇒ ∠ABD = 43°
Answer:
∠ABD = 43°
Step-by-step explanation:
Let's solve !
⇒ ∠BAC = ∠BCA = 55° (Angles opposing equal sides)
⇒ ∠BDA = 180° - 98° (Linear pair)
⇒ ∠BDA = 82°
⇒ ∠BAC + ∠BDA + ∠ABD = 180° (Angle Sum Property)
⇒ ∠ABD + 82° + 55° = 180°
⇒ ∠ABD + 137° = 180°
⇒ ∠ABD = 43°

x -6 -4 -1 3 4
f(x) 15 11 5 -3 -5
g(x) -36 -26 -11 9 14
The equations of the functions is calculated using:
[tex]y = \frac{y_2 -y_1}{x_2-x_1} * (x -x_1) + y_1[/tex]
So, we have:
[tex]f(x) = \frac{11 -15}{-4 + 6} * (x + 6) + 15[/tex]
Evaluate
f(x) = -2x + 3
Also, we have:
[tex]g(x) = \frac{-26 + 36}{-4 + 6} * (x + 6) - 36[/tex]
Evaluate
g(x) = 5x - 6
Next, we calculate (f - g)(x) using:
(f - g)(x) = f(x) - g(x)
This gives
(f - g)(x) = -2x + 3 - 5x + 6
Substitute 0 for x
(f - g)(0) = -2(0) + 3 - 5(0) + 6
Evaluate
(f - g)(0) = 9
Hence, the y-intercept of (f- g)(x) is (0,9)

Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ².
What is Pythagorean theorem?Pythagorean theorem is a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.
Mathematically, Pythagorean's theorem is given by this formula:
x² + y² = z²
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ². It is given that x² + y² = z² in triangle ABC, so z² = PQ² or AB = PQ.
The above information shows that the triangles are congruent because their three (3) sides are congruent. Therefore, to show that triangle PQR is a right triangle, we can use corresponding parts of the congruent triangles to show that PQ = AB, PR = AC and QR = BC.

Can someone help pls
Answer:
B.) No, because it fails the vertical line test.
Step-by-step explanation:
You can determine whether or not graphs represent functions by performing the vertical line test. This test states that to be a function, there must only be one output for every input. In other words, there must be only one "y" value per "x" value. As you can see, for some "x" values there is more than one "y" value.
The easiest way to perform this test is by placing your finger at the top of the graph and moving it downwards. If you cross the line twice, then it must not be a function.

Is believed that 80% of adults are honest an honesty experiment was conducted on a random sample of 50 adultsit was discovered that 42 of the adults were honestthe researcher would like to know if the data provide convincing evidence that more than 80% of adults are honest are the conditions for inference met? yesthe conditions for inference are met no, the 10% condition is not met no, the large counts condition is not met no, the randomness condition is not met
The first option, “yes, the conditions for inference are met” is correct.
What are population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
Lets you're conducting an experiment on the honesty of a random sample of 50 persons. A total of 42 adults were assessed to be trustworthy.
It has to be determined whether the conditions of inference are satisfied.
A) The randomness of the sample.
The sample is given to be randomly selected. So, this condition is satisfied.
B) The number of success and failures must be at least 10.
The success rate is 0.80, and the sample size is 50. As a result, the following conditions must be met:
[tex]\rm n_p\geq 10 \ and \ n\left ( 1-p \right )\geq 10[/tex]
[tex]\rm 50\left ( 0.80 \right )=40 > 10[/tex]
[tex]\rm 50\left ( 1-0.80 \right )=10=10[/tex]
As a result, the sample size is sufficient, and the big numbers requirement is met.
C) 10% condition:
The sample size is modest, at 50 people, and hence represents less than 10% of the population.
As a result, the inference requirements are met.
Thus, the first option “yes, the conditions for inference are met” is correct.

if abcd is a parallelogram with AB=3x-4 , BC= 2x+7 and CD = x+18 what type of paralleogram is ABCD
Answer:
rhombus
Step-by-step explanation:
If ABCD is a parallelogram, then AB and CD are opposite sides and should be equal
3x - 4 = x + 18
subtract x.
2x - 4 = 18
add 4.
2x = 22
divide by 2.
x = 11
Find the lengths of the sides.
AB= 3(11)-4 = 29
BC= 2(11)+7 = 29
CD = 11+18 = 29
If BC is 29, then DA must also be 29. So all four sides are the same, it is a rhombus.
