Because the sum of the interior angles must be 180°, we can see that the value of the third angle is 18°36'
How to find the measure of the third angle?Remember that for any triangle, the sym of the interior angles must always be equal to 180°.
So if the 3 angles are A, B, and C, we can write:
A + B + C = 180°.
In this case we can say taht:
A = 43° 36'
B = 117° 48'
Remember that 60 minutes are equal to one degree.
Now we can write:
43° 36' + 117° 48' + C = 180°
(43° + 117°) + (36' + 48') + C = 180°
160° + 84' + C = 180°
161° + 24' + C = 180°
C = 180° - 161° - 24'
C = 19° - 24'
C = 18° + 36'
The measure of the third angle is 18°36'

Lourdes is reading a biography for her history class. She reads 30 pages each day. After 9 days, Lourdes has read 3/5 of the biography. Write a linear equation to represent the number of pages Lourdes still has to read after x days.
y = []x + []
(Use above format to write the equation.)
What does the y-intercept of this linear equation represent?
A. Pages already read
B. Pages in book
C. Pages read each day
D. Days to finish
Answer:
The linear equation is y = 450 - 30 x, where y is the number of pages
Lourdes has left to read after x days
Step-by-step explanation:
Each day, Lourdes reads 30 pages of a 450-page book
- We need to write a linear equation to represent the number of pages
Lourdes has left to read after x days
∵ Lourdes reads 30 pages each day
∵ Lourdes will read for x days
∴ The number of pages Lourdes will read in x day = 30 x
- The left pages will be the difference between the total pages of the
book and the pages Lourdes read
∵ The book has 450 pages
∵ Loured will read 30 x in x days
∴ The number of pages left = 450 - 30 x
- Assume that y represents the number of pages Lourdes has left
to read after x days
∴ y = 450 - 30 x
The linear equation is y = 450 - 30 x, where y is the number of
pages Lourdes has left to read after x days
A high school is having a can food drive.
● The freshman class collected 54 more cans than the sophomore class.
The junior class collected three times the number of cans collected by the sophomore class.
The senior class collected ten cans less than the sophomore class.
Write an algebraic expression in one variable to model the total number of cans collected at the school.
●
Answer:
x + (x-10) + (x times 3) + (x+54)
Step-by-step explanation:
x = the number of cans the sophomores collected
x - 10 = the amount of cans the senior class has
x * 3 = the amount of cans the junior class has
x + 54 = the amount of cans the freshmen class has
The algebraic expression in one variable to model the total number of cans collected at the school is 5x + 44.
How to determine the algebraic expressionLet's assume the number of cans collected by the sophomore class is "x."
Now, we can express the number of cans collected by each class based on the information given:
- Freshman class: x + 54 (collected 54 more than the sophomore class)
- Junior class: 3x (collected three times the number of cans collected by the sophomore class)
- Senior class: x - 10 (collected ten cans less than the sophomore class)
To model the total number of cans collected at the school, we add the cans collected by each class:
Total cans collected = (x + 54) + 3x + (x - 10)
Now, simplify the expression:
Total cans collected = x + 54 + 3x + x - 10
Total cans collected = 5x + 44
So, the algebraic expression in one variable to model the total number of cans collected at the school is 5x + 44.

The graph shows a function. Write an equation with
the same initial value and a rate of change that is less
than the rate of change of the function shown in
the graph.
-HELP PLEASE I KNOW NOTHING ABOUT THIS..
Step-by-step explanation:
to answer the originated question first :
we know it is linear from the chart, because the function is a straight line.
we know it theoretically, when we look at x and y data pairs, and the change rate is the same constant for every x, y pair to each other.
the rate of change is also called "slope" or "incline". and it is described as ratio of "y coordinate change / x coordinate change".
it describes in fact how many units y changes, when x changes a certain amount of units (like 1).
having said all that, the most usual form as equation for such a line is the slope-intercept form.
y = ax + b
a is the slope of the line and always the factor of x.
b is the y-intercept (or the "initial value", as it is called here). it is simply the y value when x = 0.
we have 2 marked points on the line : (-2, 0) and (0, 3).
let's use them to find the slope.
going from the first to the second point
x changes by +2 (from -2 to 0).
y changes by +3 (from 0 to 3).
so, the slope (a) is +3/+2 = 3/2.
the initial value or y-intercept we get from the second point directly, as this is the point, where x = 0.
so, the initial value or y-intercept (b) is 3.
our line equation is
y = 3/2 x + 3 or 3x/2 + 3
now, we need to define a line with the same b but an a that is lower than 3/2.
since 3/2 is larger than 1, my choice for the new a would be 1 (lower than 3/2), because it is normally the easiest number to deal with.
so, the new line with lower change rate but the same initial value would be
y= x + 3
we could put it to some extreme and actually choose a = 0 (a change rate of 0).
our line equation would simply be
y = 3
this is a flat, horizontal line (parallel to the x-axis) that goes through y=3 on the y-axis.
as you can imagine, y never charged no matter what value we pick for x, so the change rate is 0. and clearly lower than 3/2.
your choice.
but how can you not know anything about this ? have you not been in the class ? but then you need to solve these questions ? that is not right.
I hope I could explain this now to you.

what is the term for the value that occurs most often in a series of numbers?
The term for the value that occurs most often in a series of numbers is called the mode.
The mode is one of the three main measures of central tendency, along with the mean and the median. It is a useful descriptive statistic that can provide insights into the characteristics of a dataset.
To find the mode of a set of data, you first need to arrange the data in order, either in increasing or decreasing order. Then, you simply identify the most frequent data point, which is the mode. In some cases, there may be more than one mode if multiple data points occur with the same maximum frequency.
The mode is particularly useful when dealing with categorical or nominal data, where there are distinct categories or values that cannot be ordered in a meaningful way. For example, the mode can help identify the most popular color among a group of people or the most common type of car on a given street. It can also be used for continuous data, although it may be less useful in this case than the mean or median.

Which of the following would produce a narrow interval than 90% confidence interval computed above?
(a) Measure the heights of a random sample of 50 6-year old girls.
(b) Measure the heights of a random sample of 10 6-year old girls.
(c) Computed 95% confidence interval rather than a 90% confidence interval
(d) Computed 99% confidence interval rather than a 90% confidence interval
(e) None of the above
Option (b) Measure the heights of a random sample of 10 6-year-old girls would produce a narrower interval than the 90% confidence interval computed above. Options (a), (c), and (d) would not produce narrower intervals, and the correct answer is (e) None of the above.
To understand which option would produce a narrower interval than the 90% confidence interval computed above, we need to consider the factors that affect the width of the confidence interval. These factors include the sample size and the chosen confidence level. (a) Option (a) suggests measuring the heights of a random sample of 50 6-year-old girls. A larger sample size tends to produce narrower confidence intervals, so this option would likely result in a wider interval than the one computed with a sample size of 18.
(b) Option (b) suggests measuring the heights of a random sample of 10 6-year-old girls. A smaller sample size results in wider confidence intervals due to increased uncertainty, so this option would likely produce a narrower interval compared to the original 90% confidence interval. (c) Option (c) suggests computing a 95% confidence interval rather than a 90% confidence interval. Increasing the confidence level leads to wider intervals to accommodate the increased level of certainty, so this option would result in a wider interval.
(d) Option (d) suggests computing a 99% confidence interval rather than a 90% confidence interval. Similarly, increasing the confidence level to 99% increases the level of certainty and widens the interval. Based on the explanations above, option (b) Measure the heights of a random sample of 10 6-year-old girls is the correct choice as it would produce a narrower interval compared to the 90% confidence interval computed above. Therefore, the answer is (e) None of the above.

"What does e to the ipi mean?

The mathematical phrase "e to the ipi" is composed of the imaginary unit i (the square root of -1 raised to the power of pi), which is symbolized by "pi," and the mathematical constant "e" (Euler's number).
The expression "e to the ipi" may be expressed as follows:
\(e^{(i*pi)}\)
The following formula is known as Euler's formula:
\(e^{(ipi)}\) = cos(pi) + isin(pi)
where "cos" and "sin" are the sine and cosine functions, respectively.
We may reduce this formula to using the cosine and sine trigonometric identities.
\(e^{(i*pi)}\) = -1
"e to the ipi" hence equals a negative one. This startling and outstanding finding ties together various crucial mathematical ideas, including calculus, complex numbers, and trigonometry.

We need to find the value of determinant det(AB), using the formula: det(AB) = det(A)det(B)
=> det(AB) = 3 × 5
=> det(AB) = 15.
Hence, the value of det(AB) is 15.
The given matrices are A and B. Here, we need to determine the value of det(AB). To calculate the determinant of the product of two matrices, we can follow this rule:
det(AB) = det(A)det(B).
Given that: det(A) = 3
det(B) = 5
Now, let C = AB be the matrix product. Then,
det(C) = det(AB).
To evaluate det(C), we have to compute C first. We can use the following method to solve the augmented matrix by elementary row operations.
Given matrices A and B are: Matrix A and B:
[A|B] = [3 0 0|1 0 1] [0 3 0|0 1 1] [0 0 3|1 1 0][A|B]
= [3 0 0|1 0 1] [0 3 0|0 1 1] [0 0 3|1 1 0].
We can see that the coefficient matrix is an identity matrix. So, we can directly evaluate the determinant of A to be 3.
det(A) = 3.
Therefore, det(AB) = det(A)det(B)
= 3 × 5
= 15.
