Explanation:
The given reflex angle is 215 degrees. A reflex angle is anything over 180 degrees, but less than 360. Subtract 215 from 360 to get the measure of angle AOB
angle AOB = 360 - 215 = 145
angle AOB = 145 degrees
We'll use this later.
Now find the area of the full circle. Use the formula A = pi*r^2. The radius is r = sqrt(10) which can be found through the distance formula or the pythagorean theorem. You want to find the length of either OA or OB to get the radius.
The area of the circle is
A = pi*r^2
A = pi*(sqrt(10))^2
A = 10pi
This is the exact area of the full circle, but we want just a fractional portion of it. Specifically we want the pie slice that is formed by angle AOB
area of sector AOB = [ (angle AOB)/360 ] * (area of full circle)
area of sector AOB = (145/360)*10pi
area of sector AOB = 145pi/36
area of sector AOB = 145*3.14/36
area of sector AOB = 12.647 approximately
area of sector AOB = 13 square units approximately, after rounding to the nearest whole number

What is the value of s?
Answers
Answer:
s = 4
Step-by-step explanation:
x is a supplementary angle or 3d angle of the triangle.
(33s - 38) + x = 180 as supplementary angles.
(4s + 43 )+ 35 + x = 180 as angles of the triangle.
(33s - 38) + x = (4s + 43 )+ 35 +x
33s - 38 = 4s + 43 + 35
33s - 4s = 43 + 35 + 38
29s = 116
s = 4

A){10,5,12}
B){1,2,3}
C){2,4,5}
D){14,48,50}
Answers
Answer:
D is the awnser
Step-by-step explanation:
i got the awsner because i first got the highest number which is 50 then i did 14^2 which is 196 then i did the same with the 48^2 2304 so then i added 2304 and 196 and got 2,500 then i did the square root and got 50 so the highest number would be the 2 nubers squared so the awnser is D

Answers
Answer:
t and u are parallel lines
s and t are also parallel lines
Step-by-step explanation:
If two parallel lines are cut by a transversal ,
then in it
pair of alternate angle are equals, similarly vice versa
if pair of alternate angle are equals then lines are parallel
pair of corresponding angles are equal and vice-versa
for example
in the given problem
if line t and u are parallel (note we have assumed this to give example of parallel lines)
then angle 7 and 9 are called alternate angles
pair of angles 5 and 9 are corresponding angles.
________________________________________________
given
∠8 = ∠10 which are alternate angles for line t and u and s is transversal for it,
thus t and u are parallel lines
___________________________
∠1 = ∠3 as they vertically opposite angles
and we know that pair of vertically opposite angles are equal
given
∠1 = ∠7
thus
∠3 = ∠7
as pair of angles ∠3 and ∠7 are corresponding angles. and are equal and hence line s and t are also parallel.

The volume of cone and cylinder are same or equal, so they are equal is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
There are two figures one is cone and other is Cylinder.
The volume of cone can be find by using πr²h/3
r=5, h=6
Volume = π(25)(6)/3
=50π
Now to find volume of cylinder.
h=50 and r=1
Volume = πr²h
=50π
the volumes are same for both cylinder and cone.
Hence, the volume of cone and cylinder are same or equal, so they are equal is correct.

Answers
Answer: Non of the options is correct.
Step-by-step explanation:
Domain of a function are the minimum and maximum values of independent variable (x).
You are given the function:
f(x) = 4x – 8
The domain can be any real numbers.
Range is the minimum to maximum value of dependent variable ( y )
From the given equation:
f(x) = 4x – 8
If the value of domain are substituted, the range will also be any real numbers.
Non of the answers is correct because both the domain and the range are all real numbers.
But the best option among the given option is option A:
domain: {x | x is a real number}; range: {y | y > –8}

An ant needs to travel along a 20cm × 20cm cube to get from point A to point B. What is the shortest path he can take, and how long will it be (in cm)?
Answers
Answer:
1. Along a diagonal, and then along an edge.
2. 48.28 cm.
Step-by-step explanation:
Assume points A and B are at diagonally opposite corners, as in the diagram below.
1. Shortest path
The shortest path is to go along the diagonal AC and continue along the edge CB.
2. Distance
The distance travelled is
d = AC + CB
According to Pythagoras,
AC² = AD² + CD² = 20² + 20² = 400 + 400 = 800
AC = √800 = 20√2
d = AC + CB = 20√ 2+ 20 ≈ 2 × 1.414 + 20 = 48.28 cm
The ant travels 48.28 cm.

After traveling by boat for 7 1⁄3 weeks, The Rohingya people had traveled 5⁄6 of the length of their trip to Malaysia. How long (in weeks) is the entire length of his trip?
Answers
Answer: 8 4/5 weeks
Step-by-step explanation:
Let the length of entire trip = 1
Length of trip already traveled = 5/6
Time taken to cover 5/6 length = 7 1/3 weeks
Then;
Length of trip left to cover = (1 - 5/6) = 1/6
Therefore, if (5/6) takes 22/3 weeks
(5/6) = 22/3
1/6 length of the trip = (22/3) ÷ 5
= (22 /3) × (1 / 5)
= 22/ 15 = 1 7/15 weeks
Therefore, length of entire trip ;
(1 / 6) * 6 --------> (22 / 15) × 6
Full length of trip = 132 / 15
Full length of trip = 8 12/15
= 8 4/5 weeks

Answers
Answer:
is greater than
Step-by-step explanation:
Mean: sum of numbers ÷ how many numbers there are

29 ÷ 6 = 4.83333
Median: middle number
3 3 4 5 5 9
4 + 5 = 9
9 ÷ 2 = 4.5
4.83333 > 4.5 so the mean is greater than the median.
