In the barn, there are horses and chickens. There are 11 heads and 32 legs altogether. How many chickens are there?
A. 6
B. 5
C. 4
D. 3
Answer:
6 Chickens
Step-by-step explanation:
Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C + 4 H = 32 (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C + H = 11 (Eq. 2)
From Eq. 2, solve for the number of chickens:
C + H = 11
C = 11 - H (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C + 4 H = 32
2 ( 11 − H ) + 4 H = 32
22 − 2 H + 4 H = 32
2H = 32 − 22
2 H = 10
H = 5 Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 = 32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
What is the measure of < B, in degrees?
Answer:
B. 32°
Step-by-step explanation:
Since two of the sides are 10 in length, then we can infer that ∠A and ∠C are congruent. So, both equal 74°. You add 74 + 74 + x = 180, x would equal 32°.
Answer:
B
Step-by-step explanation:
sum of angle in triangle is 180
and since its isosceles triangle, it means <C will be same with <A
so we know that A + C = 148.
so the value of B will be like this
B = 180° - (A+C)° = 180 - 148 = 32°

Point B has coordinates (3,2). The x-coordinate of point A is negative 9. The distance between point A and point B is 15 units. What are the possible coordinates of point A?
Answer:
(-9,9) or (-9,-7) are the possible coordinates
Step-by-step explanation:
We can use the formula for the distance between two points to get this
Mathematically, this can be;
d = √(x2-x1)^2 + (y2-y1)^2
Now let our point A be (x1,y1) = (-9,n)
let’s say y1 is n for now
For point B, we have (x2,y2) = (3,2)
and our d is 15 units
Inputing the values, we have
15^2 = (3+9)^2 + (2-n)^2
225 = 144 + (2-n)^2
225-144 = (2-n)^2
(2-n)^2 = 81
(2-n) = √(81)
2-n = -9
or 2-n = 9
n = 11 or n = -7
Now the possible coordinate values of point A are;
(-9,9) or (-9,-7)
Answer:
Step-by-step explanation:The distance between points is given by the following equation:
d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
Substituting we have:
15 = root ((- 9 -3) ^ 2 + (a-2) ^ 2)
We clear the value of a:
(15) ^ 2 = (root ((- 12) ^ 2 + (a-2) ^ 2)) ^ 2
225 = (- 12) ^ 2 + (a-2) ^ 2)
Rewriting:
225 = 144 + (a-2) ^ 2
225-144 = (a-2) ^ 2
81 = (a-2) ^ 2
a-2 = +/- root (81)
a = +/- 9 + 2
The possible values are:
a1 = 9 + 2 = 11
a2 = -9 + 2 = -7
Then, the possible coordinates of point a are:
(-11, 11)
(-11, -7)
Answer:
the possible coordinates of point a are:
(-11, 11)
(-11, -7)
What is the equation for ⨀C?
Answer:
A
Step-by-step explanation:
r^2 = (x - k)^2 + (y - h)^2
Work Shown:
(h,k) = (2,-2) is the center. So h = 2 and k = -2
r = 4 is the radius. We go 4 units from the center C to point P
Therefore,
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y-(-2))^2 = 4^2
(x-2)^2 + (y+2)^2 = 16

Explain why the initial value of any function in the form of F(x)=a(b^x) is equal to a
Answer:
When comes to initial value, x is equals to 0.
So x = 0 is substitute into the function.
In Indices Law, any values to the power of 0 will be 1.
So the initial value of function will be :
[tex]f(x) = a( {b}^{x} )[/tex]
[tex]f(0) = a \times {b}^{0} [/tex]
[tex]f(0) = a \times 1[/tex]
[tex]f(0) = a[/tex]

Also
D. 1 - sec²θ = tan²θ
The correct identity is given as follows;
1 - sec²θ = -tan²θ
2. cot(-8550)
We convert -8550 to degrees by dividing by 360 and multiplying the remaining fraction by 360 as follows;
[tex]\dfrac{-8550}{360} = -23\dfrac{3}{4}[/tex]
Therefore, -8550 ≅ -3/4×360 = -270
-270 ≅ 360 - 270 = 90°
Therefore, cot(-8550) = cot(90) = 1/(tan(90)) = 1/∞ = 0
Therefore, the correct option is the option D. 0
3. The correct option is any square is a rectangle as a square (a rectangle with all sides equal) is a subset of the set of rectangles
The correct option is C. Any square is a rectangle.
4. Where the diagonals bisect each other, we have a shape where the two opposite triangle areas across the bisector are equal
Therefore, the quadrilateral is necessarily a C. Parallelogram
5. Where by the angle of depression = 45°
Therefore, the angle of elevation = 45° (Alternate angles)
The height of the building = 30 m
Therefore, tan(45°) = (30 m)/(Distance of point A from the building) = 1
∴ The distance of point A from the building = 30 m
The correct option is therefore;
B. 30 m
6. A. -890° = 190° which is in the second quadrant
Therefore, cos(190°) = Negative
B. -1200° = -120° = 240 which is in the third quadrant
Hence, tan(-1200) = tan(240) is positive
C. Sin(1200) = Sin(120) which is in the second quadrant
Hence, sin(1200) is positive
D. Sin(-890°) = Sin(190°) which is in the third quadrant
Hence, sin(-890) is negative
7. The distance from the wall where the measurement is taken = 100/(tan(30)) = 100·√3 = 173.21 m
The total height of the antenna from the ground = 173.21 × tan(45) = 100·√3 m
The total height of the antenna from the ground is 100·√3 m
The correct option is therefore;
A. 100·√3 m
8. The coordinates of the point of intersection of the medians is given by the relation;
[tex]Centroid = \left (\dfrac{x_{1}+x_{2}+x_{3}}{3} , \dfrac{y_{1}+y_{2}+y_{3}}{3} \right )[/tex]
Where:
x₁, y₁ x₂, y₂, x₃, y₃ are the coordinates of the vertices

A carton contains 20 shirts , of which q are made of pure cotton. After 4 more pure cotton shirts are added to the carton, the probability of drawing a pure cotton shirt becomes 3/4 , find the value of q.
Answer:
The value of q = 11
Step-by-step explanation:
Number of pure cotton shirts = [tex]\frac{4+q}{20}[/tex]
Probability of drawing pure cotton shirts = [tex]\frac{4+q}{20}[/tex] = [tex]\frac{3}{4}[/tex]
Substituting the above problem = 4(4 + q) = 3 x 20
= 16 + 4q = 60
= 4q = 60 - 16 = 44
= q = [tex]\frac{44}{4}[/tex]
∴ q = 11

A number is selected from the set (1, 2, 3, 5, 15, 21, 29, 38, 500). If equal elemental probabilities are assigned, what is
the probability that the number chosen is either less than 29 or odd?
Answer:
[tex]\frac{7}{9}[/tex] OR 77.78%
Step-by-step explanation:
So, we first need to find out how many numbers fit the "less than 29 or odd" group.
This would be: 1, 2, 3, 5, 15, 21, and 29, which is a total of 7 numbers.
Next, we figure out the total amount of numbers in the population.
This would be: 1, 2, 3, 5, 15, 21, 29, 38, and 500, which is a total of 9 numbers.
Finally, we put the first number (7) over the total (9) = [tex]\frac{7}{9}[/tex]
[tex]\frac{7}{9}[/tex] is now able to be written in a percentage, if you need.
The probability is [tex]\frac{7}{9}[/tex] OR 77.78%
