Answer:
44.375sq.cm
Step-by-step explanation:
The Area of the figure = Area of the square - Area of the quadrant
Area of the square = 8 * 8 = 64sq. cm
Area of the quadrant = πr²/4 = 3.14(5)²/4
Area of the quadrant = 19.625sq.cm
Area of the figure = 64 - 19.625
Area of the figure = 44.375sq.cm

The ratio of the number of chickens to the number ducks is 7:2. The ratio of the number of ducks to the number of pigs is 5:9 There are 36 pigs on the farm.
Workout the number of chickens on the farm
Help plzz.
Answer: 70 chickens
Step-by-step explanation:
7:2
Chickens to ducks
5:9
Ducks to pigs.
There are 36 pigs. 9 is the ratio of pigs.
5 : 9
? : 36
9 x 4= 36
So multiply 5x4 to find the total ducks
=20 ducks
7 : 2
? : 20
So, 2x10 is 20 (ducks)
So 7x10 to find the chickens
(You have to balence out the sides and keep it equal
So if one side is multiplied by 10, the other is too)
7x10
= 70 chickens
The number of chickens in the farm is 70 chickens
The ratio of chickens to ducks is
7:2
The ratio of ducks to pigs is
5:9
There are 36 pigs in the farm
The first step is to calculate the total number of ducks
9-5
= 4
= 5×4
= 20 ducks
The next step is to calculate the number of chickens
= 7×10
= 70 chickens
Hence there are 70 chickens in the farm

If the mean of A and B is 20 , the mean of B and C and the mean of A,B and C us 18 . What is the mwan of A and C
Answer:
the mean of A and C is 10
Step-by-step explanation:
Given that
The mean of A and B is 20
The mean of B and C is 24
And, the mean of A, B and C is 18
We need to find out the mean of A and C
Since the mean of A and B is 20
So, a + b = 20 × 2
= 40
Likewise for B and C it is 48
And, for A, B and C, it is 54
So,
a + b = 40
b + c = 48
a + b + c = 54
So if we put the value of b + c in the above equation
a + 48 = 54
a = 6
b = 34
c = 14
Now the mean of the A and C is
= (6 + 14) ÷ 2
= 10
Hence, the mean of A and C is 10

What is the corresponding point on the unit circle for the given radian measure?
0 = 7pi/6
Answer:
Answer is B: (-sqrt(3/2 , -1/2)
Step-by-step explanation:
First convert radians to degrees
theta = (7pi/6)*(180/pi)
=210 degrees
Cos(210 degrees)= -sqrt3/2
Thats the x coordinate
sin(210 degrees)= -1/2
thats the y coordinate
Answer:
The corresponding point on the unit circle for the radian measure is [tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]
Step-by-step explanation:
What is unit circle?
A unit circle is typically drawn around the origin (0,0) of a X,Y axes with a radius of 1.
What is radian measure?
One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle.
The radian measure is,
α=[tex]\frac{7\pi }{8}[/tex]
Changing to degree measure,
[tex]\frac{7\pi }{6} *\frac{180}{\pi } \\=210^{o}[/tex]
The measure on the unit circle is,
(cos [tex]\alpha[/tex] , sin [tex]\alpha[/tex])=(cos 210 , sin 210)
=[tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]

Find the area of the regular polygon with the given radius or apothem.Shape is a hexagon with 4cm inside
Answer:
55.43cm^2
Step-by-step explanation:
Area of a hexagon given the apothem = 1/2 x perimeter x apothem
apothem = 4cm
To find the perimeter, take the following steps
4 = x√3
x = 4/√3
Multiply by 2
8√3
Since a hexagon has 6 equal sides, multiply by 6
Perimeter = 48√3
Area = (1/2) x 48√3 x 4 = 55.43cm^2

Answer:
m∠C = 26°
m∠D = 108°
m∠E = 46°
Step-by-step explanation:
Set up the equation adding the expressions together to equal 180 (sum of all angles in a triangle)
(2x) + (x+3) + (5x-7) = 180
Remove the parentheses
2x + x+ 3 + 5x - 7 = 180
Add like terms
8x - 3 -7 = 8x -4 = 180
8x - 4 = 180
Add 4 on each side to cancel it out on the right
8x - 4 = 180
+4 = +4
8x = 184
Divide each side by 8 to get the variable by itself
8/8 =1 184/8 = 23
x = 23
Substitute x in eac expression
2x = 2(23) = 46°
x + 3 = 23 + 3 = 26°
5x - 7 = 5(23) - 7 = 115 -7 = 108
Chek it by adding all the degrees to make sure it equals 180
46 + 26 + 108 = 72 + 108 = 180

Answer: $7,488
Step-by-step explanation:
For answer B:
The formula for the new balance would be A=P(1 + r)t
A = new balance
P = principal balance -> $900
r = rate (in decimal form)
t = time in years -> 8 years
To find the rate, convert 4% to decimal
4/100 = 0.04
A=P(1+ r)t
A=900(1+0.04)8

The height in feet,h , of a model rocket t seconds after launch is given by the equation h(t) = 3+70t-16t^2.
Answer:
speed of the rocket is 6feet
Step-by-step explanation:
Complete question
The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
Note that the average rate is also known as the speed
Average rate = h(3)-h(1)/3 - 1
h(3) = 3+70(3) - 16(3)^2
h(3) = 3 + 210 - 144
h(3) = 69
h(1) = 3+70(1) - 16(11)^2
h(1) = 3 + 70 - 16
h(1) = 73 -16
h(1) = 57
Average rate = 69-57/3-1
Average rate = 12/2
Average rate = 6ft/s
This shows that the speed of the rocket is 6feet
Answer:
If you're looking for the answer for edge, its;
B. The rocket is at a greater height when t = 3 than when t = 1.

The probability of getting a blue marble is 0.15.
What is probability?The probability of an event is a number that indicates how likely the event is to occur.
Given that, a bag contains marbles of four different colors: 8 blue marbles, 24 red marbles, 16 green marbles and 4 yellow marbles,
We need to find the probability of picking a blue marble at random out of the bag,
Probability(Event) = Favorable Outcomes / Total Outcomes
Favorable Outcomes = 8
Total Outcomes = 52
Therefore,
P(blue marble) = 8/52 = 0.15
Hence, the probability of getting a blue marble is 0.15.
