Answer:
x=60
Step-by-step explanation:
here DOB and AOC are vertically opposite angles and the values of them are equal. so lets take the two angles as y.
x+DOB is 90(because EOA is 90 and the sum of angles in a straight line is 180), DOB is y and can write a equation as x+y=90
and 30+2x+y = 180 ,
2x+y=150, (180-30)
then two equations can be made.
x+y=90
2x+y=150
simplifying these two simultaneous equations
can get x as 60. and 2x is 120.
The value of x is 60°
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Here, DOB and AOC have equal values and are at vertically opposed angles. Let's use y to represent the two angles.
Since EOA is 90 and the total of the angles in a straight line is 180, x+DOB equals 90 and can be written as x+y=90.
And 30 + 2x + y = 180 ,
⇒ 2x+y = 180-30
⇒ 2x + y = 150,
After which two equations can be created.
⇒ x+y=90
⇒ 2x+y=150
We have the two simultaneous equations made simpler.
We can get x as 60. and 2x as 120.
Thus, the value of x is 60°

The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and standard deviation is 4 beads. Which sentence most closely summarizes the data?
About 80 necklaces have more than 28 beads. Then the correct option is C.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and the standard deviation is 4 beads.
P(x > 28) = P(x - 24 / 4 > 28 - 24 / 4)
P(x > 28) = P(x - 24 / 4 > 1)
P(x > 28) = 1 - ∅1
P(x > 28) = 1 - 0.8413
P(x > 28) = 0.1587
Multiply both sides by 500, then we have
500 P(x > 28) = 0.1587 × 500
500 P(x > 28) = 79.35
500 P(x > 28) ≈ 80
About 80 necklaces have more than 28 beads. Then the correct option is C.

Answer:
(4p x 4) x 2 = 16p x 2 = 32p
Step-by-step explanation:
The required simplification is (4p⁴)² = 256p⁸.
What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
The given expression is as below,
(4p⁴)²
Without using the exponents the given expression can be simplified as follows,
The power to any number simply means that the number will be multiplied to itself as many number of times. this basic rule is used to obtain result as,
(4p⁴)²
= (4p × 4p × 4p × 4p)²
= (16p⁴)²
= 16p⁴ × 16p⁴
= 256 × (p × p × p × p × p × p × p × p)
= 256p⁸

Given f(x) and g(x), find f(x)g(x)
and any domain restriction.
\(\frac{f(x)}{g(x)} =\frac{x+2}{x^2+1}\) for all x.
Step-by-step explanation:As we may see on this expression, it's a fraction of functions. Hence, the only thing that can prevent the expression from giving a defined result is that the denominator equals 0. Therefore, those values of x that make the denominator function equal 0 are going to be the ones than cannot be considered as domains of this fraction of functions. Let's solve equation g(x) when y= 0 to find the values.
\(0=x^2+1\\ \\x^2=-1\\\sqrt{x^2} =\sqrt{-1} \\x=-i\)
No real solutions where obtained, this means that function g(x) has a domain of all real numbers. Therefore, the function of f(x)/g(x) has a domain of all x values.

domain is x is all real numbers where x does not equal 1 comma range is y is all real numbers where y does not equal 7
The domain of the given quantity is all the real numbers except 1.
And range of the function is all the real numbers.
What is domain and range ?All the potential values of the independent variable, x, for which y is specified, constitute the domain and range of a function. Every possible value of the dependent variable y falls inside a function's range.
We have the given quantity
\(\frac{3x^{2} +x-4}{x - 1}\)
So, we can say that now we have a function, let f(x) be the function such that
f(x)= \(\frac{3x^{2} +x-4}{x - 1}\)
As from the fact that, the set of all input values for which this function is defined is called the domain of the function.
And the set of values for the input values is called the range of the given function.
Here, function is not defined for x = 1.
Because if we put x = 1, we get denominator 0. And (something / 0) is not defined.
So, we can input any real numbers for x in function f(x) except 1. Because at x = 1 our function is not defined.
Therefore, the domain of given function f(x) is all the real numbers except 1.
And, if we input all the real numbers in function f(x) we get only real numbers as the output. Therefore, the range of the given quantity or function is real numbers.
Hence, the domain of the given quantity is all the real numbers except 1.
And range of the function is all the real numbers.

Winston earns $140.00 by selling 56 hot dogs at a concession stand at school. Using the same rate for the cost of one hot dog, how many hot dogs would Winston need to sell to earn a total of $175.00?
A. 14
B. 70
C.350

56 hot dogs cost 140 dollars
1 hot dog costs 140/56 = 2.50
How many hot dogs would you need to see to get 175 dollars.
x * $2.50 = $175

Solve and graph. |2x(x-1)+12|<=18
The solution of the inequality is -1 ≤ x ≤ 3.
To solve the inequality |2x(x-1)+12| ≤ 18, we can break it down into two separate inequalities:
2x(x-1) + 12 ≤ 18
-(2x(x-1) + 12) ≤ 18
Solving the first inequality:
2x(x-1) + 12 ≤ 18
2x² - 2x + 12 ≤ 18
2x² - 2x - 6 ≤ 0
Solving the second inequality:
-(2x(x-1) + 12) ≤ 18
-2x(x-1) - 12 ≤ 18
-2x² + 2x - 12 ≤ 18
2x² - 2x + 30 ≤ 0
Now, let's solve each inequality separately.
For the first inequality, 2x² - 2x - 6 ≤ 0:
We can factor this quadratic equation:
(2x + 2)(x - 3) ≤ 0
To determine the sign of the inequality, we need to consider the intervals where the expression is positive or negative. We set each factor equal to zero to find the critical values:
2x + 2 = 0 => x = -1
x - 3 = 0 => x = 3
Plotting these critical values on a number line and testing intervals, we find that the solution is -1 ≤ x ≤ 3.
For the second inequality, 2x² - 2x + 30 ≤ 0:
This quadratic equation does not have real solutions, so there are no solutions to this inequality.
Combining the solutions from both inequalities, we have -1 ≤ x ≤ 3.
To graph the solution, we plot the interval -1 ≤ x ≤ 3 on the number line. The shaded region on the number line represents the solution set.
