The length XY of the circle X is the radius of the circle
The length of XY is 9 units
How to determine the length of XY?The parameters are given as:
Length of arc, YZ = 5πCentral angle, YXZ = 100°The length of arc is calculated using:
L = Ф/360 * 2πr
Where:
L = YZ = 5πФ = YXZ = 100°Radius, r = XYSo, we have:
5π = 100/360 * 2πr
Evaluate the quotient
5π = 5/9 * πr
Divide both sides by 5π
1 = 1/9 * r
Multiply both sides by 9
r = 9
This means that
XY = r = 9
Hence, the length of XY is 9 units

Answer:
B (x= 14/3 , y= -5/3)
Step-by-step explanation:
A (x= 6, y= 1) and C (x= 2, y = -7)
On x-axis between A and C are 6 -2 = 4 units
On y-axis between A and C are 1 + 7 = 8 units
AB = (1/3) BC
Divide the distance between AC in 3 pieces
On x-axis will have 4/3 units on each piece
On y-axis will have 8/3 units on each piece
Now move away from A the 1/3 distance
A (x= 6, y= 1)
B (x= 6 -(4/3) , y= 1 -(8/3))
B (x= (18- 4)/3) , y= (3-8)/3))
B (x= 14/3 , y= -5/3)

Find the perimeter and area of the shaded region.
Answer:
1. 144 m; 2. 720m²;
Step-by-step explanation:
1.
First we need to know how much edges are of the figure. Since there is 12, we need to multiple the length of an edge to how many of them are:
12 • 12 = 144 m
2.
Since one edge is 12 m, first calculate the plot of a little square (as there are 5 in the pic):
12 • 12 = 144 m² (one square)
Now we know that one square's plot is 144 m².
Since there is 5 of them, we need to multiply the plot 5 times, since there are five mini squares:
144 • 5 = 720 m²
Now we know the plot of the full figure.

Answer:
[tex]3\ \frac{15}{16}[/tex]
Step-by-step explanation:
The mixture requires 3/8 cup of plant food for every gallon of water
Then it requires (10 1/2)×(3/8) cup of plant food for 10 1/2 gallons of water
Now we have to calculate (10 1/2)×(3/8)
[tex]10\ \frac{1}{2} \ =\ \frac{10\times 2}{2} +\frac{1}{2} \ =\frac{20+1}{2} =\frac{21}{2}[/tex]
[tex]\frac{21}{2} \times \frac{3}{8} =\frac{63}{16} =3\ \frac{15}{16}[/tex]

Probability which can be classified as an event
The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible. Converting the fraction 35 to a decimal, we would say there is a 0.6 probability of choosing a banana. This basic definition of probability assumes that all the outcomes are equally likely to occur.

In a certain Algebra 2 class of 21 students, 12 of them play basketball and 14 of them play baseball. There are 5 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?
The probability that a student is chosen randomly from the class plays both basketball and baseball is 4/21
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcomeIf the total number of people in the class is 21 students, hence the total outcome is 21Get the number of students that plays both basketball and baseball
n(U) = n(B)only + n(Ba)only + n(BnBa) + n(BuBa)'
21 = 6-x + 14-x + x + 5
21 = 25 -x
x = 25 - 21
x = 4
Hence 4 students play both basketball and baseball
Pr(basketball and baseball) = 4/21
Hence the probability that a student chosen randomly from the class plays both basketball and baseball is 4/21

Find the area of the figure
Answer:
132cm^2
Step-by-step explanation:
to solve for the area of this we can split it into smaller shapes and sum the areas afterward-
the top rectangle has an area equal to Length x Width
4x7 = 28cm^2
the centre rectangle is done similarly-
7x8 = 56cm^2
lastly the two triangles which are solved with base x height divided by two
now since we know that the centre piece is 7cm across, and that the two side triangles are equal in size, that means that we know the base to be 19-7 divided by 2 which gives 6 each-
[tex]\frac{(6)(8)}{2}[/tex] (2) = (6)(8) = 48cm
now summing them we have 28 + 56 + 48 = 132cm^2
