Find value of x in trapezoid
Answers
Answer:
x = 1
Step-by-step explanation:
You want to know the value of x in the trapezoid with adjacent angles (43x+2)° and 135°.
Supplementary anglesThe two marked angles can be considered "consecutive interior angles" where a transversal crosses parallel lines. As such, they are supplementary.
(43x +2)° +135° = 180°
43x = 43 . . . . . . . . . . . . . . divide by °, subtract 137

If the area of the rectangle is 180 in find its perimeter.
Answers
Answer:
72
Step-by-step explanation:
l = 5w
A = l*w
180 = 5w *w
180 = 5w^2
Divide each side by 5
180/5 = 5w^2 /5
36 = w^2
Taking the square root of each side
sqrt(36) = sqrt(w)^2
6 =w
l = 5w = 5*6 = 30
The perimeter is
P = 2(l+w)
P = 2(6+30) = 2(36) = 72

find the exact value of x. 45 degree and 10 side
Answers
Answer:
The exact value of the other leg is 10.
Step-by-step explanation:
Finding the exact value of x given a 45 degree angle and a side length of 10 can be done using trigonometry. In a 45-45-90 right triangle, the two legs are congruent and the hypotenuse is equal to the square root of 2 times the length of the legs.
Therefore, if one leg is 10, the hypotenuse is 10 times the square root of 2. To find the length of the other leg, we can use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the legs of the right triangle.
Substituting known values, we get:
(10√2)^2 = 10^2 + b^2
200 = 100 + b^2
b^2 = 100
b = 10
Therefore, the exact value of the other leg is 10.

Consider the following story:
Three men walk into a hotel and ask to share a room. The cost is going to be $270 for
the night. Each man puts in a $100 bill and they get 3 $10 bills in change. The bell boy
carries their luggage and they each decide to be generous and tip the bell boy their change.
The front desk realizes they miss-charged the men, so the bell boy takes a $20 bill change to
the room. The men realize that you can’t split the $20 bill evenly 3 ways so they add it onto
the tip. The bell boy is happy but then thinks to himself: ”If the room is $270 and they had
this extra $20 that’s only $290, where did the other $10 go?”
Explain what is wrong with the Bell Boy’s thoughts, and what is the correct math here.
Answers
Answer:
Step-by-step explanation:
The bell boy added $270 and $20 incorrectly. The $20 bill was something that was returned due to overcharching. On the other hand, $270 was the amount that they paid for their room. This only means that $20 should be deducted from $270 and that's the amount that they paid for their room while $30 and $20 are the amount that the bell boy received as a tip
Total money of the three men: 3($100) = $300
They paid $270 for the room: $300 - $270 = $30
Tip for the bell boy: $30 - $30 = $0
Amount overcharged to them: $0 + $20 = $20
Tip to the bell boy: $20 - $20 = $0
They were left with no more money from the original $300.

Answers
Answer:
113
Step-by-step explanation:
First we need to find theother 2 angles of the triangle.
We are given that the top angle is 60°
We know that the angles of a triangle add up to 180°
To find the bottom left angle of the triangle...
We can see that it is alternate exterior angles so they will equal.
To find the third angle of the triangle...
180 - 60 (given angle) -53 (alternate exterior angle) = 67°
Now we know that the bottom right angle inside the triangle is 67°.
To find x...
subtract 67 from 180 because the like is a combination of x and the 67° angle we just found. (a straight line angle = 180°)
180 - 67 = 113

We can start by finding the equation of the line passing through the given points. Using the point-slope form of the equation of a line, we have:
What is the point-slope form?Point-slope form is a way to express the equation of a straight line, using a point on the line and its slope. Given a point (x1, y1) on the line and the slope m, the point-slope form of the equation of the line is:y - y1 = m(x - x1)
y - (-1) = (1 - (-1)) / (-4 - (-3)) * (x - (-4))
y + 1 = 2(x + 4)
y = 2x + 9
The graph of the line passes through the points (-4, -1), (-3, 1), (-2, 3), (-1, 5), (0, 7), and so on.
To find the equation of the function g(x) = f(x+3), we can substitute x+3 for x in the equation of the line, which gives:
y = 2(x+3) + 9
y = 2x + 15
This is the equation of a line with slope 2 and y-intercept 15. We can use this equation to answer the questions:
The value of g(-5) is 3:
To find g(-5), we substitute x = -5 into the equation of g(x):
g(-5) = 2(-5) + 15 = 5
Therefore, the statement "The value of g(-5) is 3" is false.
The value of g(-1) is 2:
To find g(-1), we substitute x = -1 into the equation of g(x):
g(-1) = 2(-1) + 15 = 13
Therefore, the statement "The value of g(-1) is 2" is false.
The x-intercept of g(x) is to the left of the x-intercept of f(x):
The x-intercept of f(x) is approximately (-4.5, 0). To find the x-intercept of g(x), we set y = 0 in the equation of g(x):
0 = 2x + 15
x = -7.5
Therefore, the x-intercept of g(x) is to the left of the x-intercept of f(x), and the statement "The x-intercept of g(x) is to the left of the x-intercept of f(x)" is true.
The x-intercept of g(x) is to the right of the x-intercept of f(x):This statement is false based on the result of the previous question.The y-intercept of g(x) is lesser than the y-intercept of f(x):The y-intercept of f(x) is approximately (0, 7). The y-intercept of g(x) is 15. Therefore, the statement "The y-intercept of g(x) is lesser than the y-intercept of f(x)" is false.The y-intercept of g(x) is greater than the y-intercept of f(x):This statement is true based on the result of the previous question.

Calculate the price of a zero-coupon bond that matures in five years if the market interest rate is 7.50 percent. (Assume semiannual
compounding and $1,000 par value.)
Multiple Choice
Answers
Based on the information given, the price of the zero coupon bond is $692.04.
How to solveTo calculate the price of a zero coupon bond, we need to use the following formula:
\(\sf P =\dfrac{F}{1+r\div n}^{(nt)\)
Where:
P = price of the bondF = face value of the bondr = annual interest raten = number of compounding periods per yeart = time to maturity in yearsAlso, the annual interest rate is 7.50%, which is the market interest rate, and the compounding is semiannual, which means n = 2. Finally, the time to maturity is 5 years.
Plugging in the values into the formula, we get:
\(\sf P = \dfrac{1000}{(1+0.075\div2)^{(2\times5)}}\)
\(\sf P = \dfrac{1000}{(1.0375)^{10}}\)
\(\sf P = \dfrac{1000}{1.4450}\)
\(\sf P = \$692.04 \ \ (rounded \ to \ the \ nearest \ cent)\)
Therefore, the price of the zero coupon bond is $692.04.

The domain of function A and function B are compared by the statement of Option A: The domain of Function A is the set of real numbers greater than 0. The domain of Function B is the set of real numbers greater than or equal to 1.
What is a function?
A function is a fundamental concept in mathematics that relates a set of inputs (also known as the domain) to a corresponding set of outputs (sometimes referred to as the codomain). For each input, there exists exactly one output, and the output can be linked to its corresponding input in a unique manner.
The domain of a function refers to the set of all possible input values for which the function can produce an output.
In Function A, the domain consists of all real numbers greater than 0, since it is a logarithmic function that can take any positive number as an input.
In contrast, the domain of Function B includes all real numbers greater than or equal to 1, since it is a square root function that begins at (1,0) and continues to infinity.
This means that any number greater than or equal to 1 can be used as an input to produce a corresponding output.
It is essential to define the domain of a function accurately to ensure that the function is well-defined and to avoid potential errors or ambiguities in mathematical computations.
Therefore, the correct statement is A.
