ABC is a triangle inscribed in a circle with center O. If ∠A OC =130° and ∠B OC =150°, find ∠A CB.
Answer:
65°
Step-by-step explanation:
Since the triangle ABC is inscribed in a circle with center O, we know that the angles subtended by any chord of the circle are equal. Therefore, we have:
∠AOC = 2∠ACB (angle subtended by chord AC)
∠BOC = 2∠BCA (angle subtended by chord BC)
Substituting the given values, we get:
130° = 2∠ACB
∠ACB = 65°
150° = 2∠BCA
∠BCA = 75°
Finally, we can use the fact that the sum of angles in a triangle is 180° to find ∠CAB:
∠CAB = 180° - ∠ACB - ∠BCA
∠CAB = 180° - 65° - 75°
∠CAB = 40°
Therefore, the measure of ∠ACB is 65°.

Directions if l || m solve for x and y
Answer:
x = 11
y = 3
Step-by-step explanation:
Okay so we know that l is parallel to m. We also know that (9x + 25) and (13x - 19) are the same because they are corresponding angles. So to find x just set them equal to each other and solve.
(9x + 25) = (13x - 19)
-9 -9
---------------------
25 = 4x - 19
+19 +19
-----------------
44 = 4x divide both sides by 4 and x equals 11
Now, we know that a straight line equals 180º so we just plug x into the first equation, and set both equations to equal 180. It should look like
(13 x 11 - 19) + (17y + 5) = 180
13 x 11 = 143
(143 - 19) + (17y + 5) = 180
143 - 19 = 124 + 5 = 129
129 + 17y = 180
-129 -129
17y = 51
Divide by 17 from both sides and y = 3
Answer:
x = 11 and y = 3
Step-by-step explanation:
(13x - 19) and (9x + 25) are corresponding angles and congruent, thus
13x - 19 = 9x + 25 ( subtract 9x from both sides )
4x - 19 = 25 ( add 19 to both sides )
4x = 44 ( divide both sides by 4 )
x = 11
Then
13x - 19 = 13(11) - 19 = 143 - 19 = 124
(17y + 5) and (13x - 19) are adjacent angles and are supplementary, thus
17y + 5 + 124 = 180, that is
17y + 129 = 180 ( subtract 129 from both sides )
17y = 51 ( divide both sides by 17 )
y = 3
(x,3) and (7,-5) given m= -8/7
Answer:
(0, 3)Step-by-step explanation:
The slope-intercept form of an equation of a line:
\(y=mx+b\)
\(m\) - slope
\(b\) - y-intercept
Given
\(m=-\dfrac{8}{7}\)
and point \((7;\ -5)\)
Substitute the value of the slope and the coordinates of the point ot the equation of a line:
\(-5=-\dfrac{8}{7\!\!\!\!\diagup}\cdot7\!\!\!\!\diagup+b\) cancel 7
\(-5=-8+b\) add 8 to both sides
\(-5+8=-8+8+b\)
\(3=b\to b=3\)
Therefore we have the equation of the line:
\(y=-\dfrac{8}{7}x+3\)
Substitute (x, 3) to the equation:
\(3=-\dfrac{8}{7}x+3\) subtract 3 from both sides
\(3-3=-\dfrac{8}{7}x+3-3\)
\(0=-\dfrac{8}{7}x\) divide both sides by (-8/7)
\(0=x\to x=0\)

I assume you want me to simplify the expression you provided. To simplify it, we can combine the terms that have the same denominator and then simplify each term individually.
First, let's find a common denominator for all the terms:
x+2(x-1)^2(x+1)^3 - 2(x-1)^2 - 3(x+1)^3
Next, we can simplify each term individually:
x: This term has the same denominator as the common denominator, so we can just write x as (x+1)^3/(x+1)^3.
2/(x-1)^2: This term has a denominator of (x-1)^2, so we can write it as 2/(x-1)^2.
-2/(x-1)^2: This term is already in its simplified form.
-3/(x+1)^3: This term has a denominator of (x+1)^3, so we can write it as -3/(x+1)^3.
Putting it all together, we get:
x+2(x-1)^2(x+1)^3 - 2(x-1)^2 - 3(x+1)^3
= (x+1)^3/(x+1)^3 + 2/(x-1)^2 - 2/(x-1)^2 - 3/(x+1)^3
= (x+1)^3/(x+1)^3 - 3/(x+1)^3
Therefore, the simplified expression is:
(x+1)^3/(x+1)^3 - 3/(x+1)^3
Simplifying further, we get:
1 - 3/(x+1)^3
So the final simplified expression is:
1 - 3/(x+1)^3

The required value of x is 22 degrees for the given figure.
Adjacent angles are a sort of additional angle. Adjacent angles share a common side and vertex, such as a corner point. Their points do not overlap in any manner.
As we know that supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.:
According to the given figure, it can be written as follows:
2x + 24 + 6x - 20 = 180
8x + 4 = 180
8x = 180 - 4
8x = 176
x = 176/8
x = 22
Therefore, the required value of x is 22 degrees for the given figure.

How many solutions does the system of linear equations have?
A. No solution
B. Infinitely many solutions
C. One solution at (4,0)
D. One solution at (0,-1)
Answer:
Step-by-step explanation:
The slopes of both those lines are the same so there is no solution. Use slope triangles to find out the slope. They are both 1/4.
A. No solution
y = 1/4x+5
x - 4y = 4
You can simplify the second equation into y = 1/4x - 1
Since these equations both have the same slope, they are parallel. When two lines are parallel, they have no solutions.

It is difficult to determine which sample will be the most representative without more information.
There are a few factors to consider when evaluating the representativeness of a sample:
Sample size: Larger sample sizes are generally more representative because they include more individuals, which makes it less likely that the results will be biased.
Sampling method: Random sampling methods, such as Ruth's method of calling randomly selected registered voters, are generally more representative than other methods because they aim to include a representative sample of the population.
Population: The population being surveyed will also impact the representativeness of the sample. For example, if Levonia's friends are not representative of the general population, her sample may not be representative.
Overall, it is important to consider all of these factors when evaluating the representativeness of a sample.

What is the approximate lateral area of the cone?
Use π≈3.14.
round to the nearest whole number.
Answer:
Step-by-step explanation:
To find the exact surface area of the cone, we need to know the slant height of the cone. Since we are not given the slant height, we can use the Pythagorean theorem to find it:
Slant height² = h² + r²
Slant height² = 4² + 3²
Slant height² = 16 + 9
Slant height² = 25
Slant height = 5
Now that we know the slant height, we can use the formula for the surface area of a cone:
Surface area = πr² + πr×s
where s is the slant height
Surface area = π(3²) + π(3)(5)
Surface area = 9π + 15π
Surface area = 24π
Therefore, the exact surface area of the cone is 24π square units.
The surface area of a cone is given by:
Surface area = πr² + πr×s
where r is the radius of the circular base and s is the slant height.
We are given that the diameter of the circular base is 6 inches, so the radius is 3 inches. We are also given that the slant height is 8 inches. Using these values, we can calculate the surface area of the cone:
Surface area = π(3²) + π(3)(8)
Surface area = 9π + 24π
Surface area = 33π
We can approximate π as 3.14, so:
Surface area ≈ 33(3.14)
Surface area ≈ 103.62
Therefore, the approximate surface area of the cone is 103.6 in², which is closest to option (B).

The gate code to a gated community consists of the # key, followed by 3 letters chosen from the English alphabet, followed by 3 digits. What is the total number of possible gate codes?
The gate code to a gated community consists of the # key, followed by 3 letters chosen from the English alphabet, followed by 3 digits. The total number of possible gate codes is 17.576,000.
To find the total number of possible gate codes for the gated community, we need to determine the number of choices for each part of the code and multiply them together.
1. The gate code starts with the # key, which is constant, so there's only 1 choice for this part.
2. The next part consists of 3 letters chosen from the English alphabet. There are 26 letters in the alphabet, and each of the 3 positions can be filled with any of those letters. So, the number of choices for this part is 26 * 26 * 26.
3. The last part of the code consists of 3 digits. Since there are 10 digits (0-9), there are 10 choices for each digit. Therefore, there are 10 * 10 * 10 choices for this part.
Now, we'll multiply the number of choices for each part together to get the total number of possible gate codes:
1 * (26 * 26 * 26) * (10 * 10 * 10) = 1 * 17576 * 1000 = 17,576,000
So, there are a total of 17,576,000 possible gate codes for the gated community.

Therefore, the compound interest of the annuity due of BD 400 paid each 4 months for 6.2 years at a nominal rate of 3% per annum is BD 40,652.17.
Compound interest of an annuity due can be calculated using the formula:A = R * [(1 + i)ⁿ - 1] / i * (1 + i)
whereA = future value of the annuity dueR = regular paymenti = interest raten = number of payments First, we need to calculate the effective rate of interest per period since the nominal rate is given per annum. The effective rate of interest per period is calculated as
:(1 + i/n)^n - 1 = 3/1003/100 = (1 + i/4)^4 - 1
(1 + i/4)^4 = 1.0075i/4 = (1.0075)^(1/4) - 1i = 0.0303So,
the effective rate of interest per 4 months is 3.03%.Next, we can substitute the given values in the formula:
A = BD 400 * [(1 + 0.0303)^(6.2 * 3) - 1] / 0.0303 * (1 + 0.0303)A = BD 400 * [4.227 - 1] / 0.0303 * 1.0303A = BD 400 * 101.63A = BD 40,652.17
