please answer
the measures of the angles of the triangle are A = 26.29 degrees, B = 131.45 degrees, and C = 22.29 degrees.
How to solve angles?
To solve for the angles of a triangle, we need to use the fact that the sum of the angles of a triangle is equal to 180 degrees. We can use this fact to set up equations based on the given information.
Let's start by assigning variables to the angles of the triangle. Let A be the measure of angle A, B be the measure of angle B, and C be the measure of angle C.
We are given that angle B is 5 times angle A, which we can express as B = 5A. We are also given that angle C is 4 times less than angle A, which we can express as C = A - 4.
Using the fact that the sum of the angles of a triangle is 180 degrees, we can write the following equation:
A + B + C = 180
Substituting the expressions we found for B and C, we get:
A + 5A + (A-4) = 180
Simplifying the equation, we get:
7A - 4 = 180
Adding 4 to both sides of the equation, we get:
7A = 184
Dividing both sides by 7, we get:
A = 26.29
Now that we know the measure of angle A, we can use the expressions we found for B and C to find their measures:
B = 5A = 131.45
C = A - 4 = 22.29
Therefore, the measures of the angles of the triangle are A = 26.29 degrees, B = 131.45 degrees, and C = 22.29 degrees.
In summary, we used the fact that the sum of the angles of a triangle is 180 degrees and the given information about the relationship between the angles to set up an equation and solve for the measure of angle A. We then used the expressions we found for angles B and C to find their measures.

how do you turn 9^-6 to a positive exponent?
[tex]9^(-6)[/tex] is the reciprocal of [tex]9^6[/tex], which is a positive number, and has the same value as [tex](1/9)^6[/tex] based on exponent.
A mathematical procedure known as an exponent entails elevating a number or variable to a specific power or degree. The base number or variable's exponent specifies how many times it has been multiplied by itself.
An exponent's basic form is as follows:
[tex]a^n[/tex]
where "n": the exponent or power and "a": the base number or variable. To the right of the base number "a," a superscript denotes the exponent "n."
Using the following rule, we can make [tex]9^(-6)[/tex] a positive exponent:
[tex]a^(-n) = 1 / a^n[/tex]
A is 9 and n is 6 in this instance. Thus, it can now be written as:
[tex]9^-6 = 1 / 9^6[/tex]
We must now simplify 1/96. To accomplish this, we can apply the following rule:
[tex]a^n / a^m = a^ (n-m)[/tex]
A is 9 and n is 6 in this instance. Rewriting 1/9/6 results in:
[tex]1/9^6 = 9^(-6) (-6)[/tex]
Once more using the method above, we may express 9(-6) as follows:
[tex]9^(-6) = 9^(0 - 6) = 9^0 / 9^6 = 1/9^6[/tex]
Hence, we have demonstrated that 1/9/9/6 = 9/-6. Thus, we only need to rewrite 9-6 as follows to make it a positive exponent:
[tex]9^(-6) = 1 / 9^6[/tex]
This indicates that the reciprocal of the positive number 96, which has the same value as [tex](1/9)^6[/tex], is [tex]9^(-6)[/tex].

Part a. Fencing that will be used more = 24ft.
Part b. Area of proposed space greater than area of current space
= 276ft²
Define a rectangle?A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. Around us, there are a lot of rectangle items. The length and width of each rectangle serve as its two distinguishing attributes. The width and length of a rectangle, respectively, are its longer and shorter sides.
In the given question,
Length of current space, l = 24ft.
Breadth of current space, b = 16 ft.
Length of proposed space = 24 + 3 + 3 = 30ft.
Breadth of proposed space = 16 + 3 + 3 = 22ft.
Part a.
Perimeter of current space = 2 (l + b)
= 2 × (24 + 16)
= 2× 40
= 80ft.
Perimeter of proposed space = 2 × (30+22)

Terri tracks time in minutes she spends each morning at the fitness club what is the most appropriate measure of variability for Terri’s data?
A: mean
B:median
C:range
D:interquartile range (IQR)
After answering the presented question, we can conclude that it contains inequality the extremes of Terri's data, which may not be representative of her typical time spent at the fitness club.
What is inequality?In mathematics, an inequality is a non-equal connection between two expressions or values. As a result, imbalance leads to inequity. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two values are not equal, the not equal symbol is typically used (). Various disparities, no matter how little or huge, are utilised to contrast values. Many simple inequalities can be solved by altering the two sides until just the variables remain. Yet, a lot of factors contribute to inequality: Negative values are divided or added on both sides. Exchange left and right.
The interquartile range is the most acceptable measure of variability for Terri's data (IQR).
The IQR is an acceptable measure of variability in this example because it focuses on the middle 50% of the data, which is where Terri spends the majority of her time at the fitness club. The mean and median are measures of central tendency rather than variability, and the range would be less useful in this situation because it contains the extremes of Terri's data, which may not be representative of her typical time spent at the fitness club.

9/5 * x
So answer will be as follows:
(24x^(3))/(50x)*(30)/(8x^(2)) = 9/5 * x
A mouse has made holes in opposite corners of a rectangular kitchen.
The width of the kitchen is 12 feet and the distance between the mouse's holes is
15 feet.
What is the length of the kitchen?
The length of the rectangular kitchen with a width of 12 feet and holes in opposite corners, 15 feet apart, is 9 feet.
To solve this problem, we need to use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides (the legs) is equal to the square of the longest side (the hypotenuse).
Therefore, we can use the Pythagorean theorem to solve for the length of the kitchen, which is the unknown side of the right triangle.
Let's call the length "L". We know that the width is 12 feet and the distance between the mouse's holes (which is the hypotenuse of a right triangle) is 15 feet. So, we have:
[tex]L^2 + 12^2 = 15^2[/tex]
Simplifying:
[tex]L^2 + 144 = 225[/tex]
Subtracting 144 from both sides:
[tex]L^2 = 81[/tex]
Taking the square root of both sides:
L = 9
Therefore, the length of the kitchen is 9 feet.

The condition that must be satisfied to use a chi-square goodness-of-fit test is D. The expected count for each category is at least 5.
A chi-square goodness-of-fit test is a statistical test used to determine whether the observed frequencies of categorical data match the expected frequencies. This test is often used to analyze categorical data, such as determining if the distribution of colors in a bag of candies matches the expected proportions.
The reason behind this condition is that the chi-square test is based on the assumption that the data follow a specific distribution. When the expected count for each category is less than 5, the test might not accurately represent the true distribution, and the results may be misleading. By having an expected count of at least 5 in each category, the test can better approximate the true distribution and provide more reliable results. Therefore, option D is correct.

a grab bag contains 2 football cards and 8 basketball cards. an experiment consists of taking one card out of the bag, replacing it, and then selecting another card. what is the probability of selecting a football card and then a basketball card? express your answer as a decimal.
The probability of selecting a football card and then a basketball card is 0.16 or 16%. The probability of selecting a football card and then a basketball card can be calculated by multiplying the probability of selecting a football card on the first draw and the probability of selecting a basketball card on the second draw.
Since the first card is replaced before the second draw, the probability of selecting a football card or a basketball card remains the same on both draws.
The probability of selecting a football card on the first draw is 2/10, or 0.2, since there are 2 football cards in a total of 10 cards in the bag. The probability of selecting a basketball card on the second draw is 8/10, or 0.8, since there are 8 basketball cards left after the first draw.
Therefore, the probability of selecting a football card and then a basketball card can be calculated as follows:
P(Football and Basketball) = P(Football on 1st draw) x P(Basketball on 2nd draw)
= (2/10) x (8/10)
= 0.16
So, the probability of selecting a football card and then a basketball card is 0.16 or 16%.

As a result, we have demonstrated: 1 / (cos(x) - cot(x)) = cos (x) + cot(x) as the right side of the equation .
what is trigonometric ratios ?Trig ratios are ratios between the sides and angles of a right triangle. The sine, cosine, and tangent are the three main trigonometric ratios (tan). These are their definitions: The ratio of a right triangle's hypotenuse's length to the height of the opposite end is known as the sine (sin) of an angle. The ratio of a right triangle's neighbouring side to hypotenuse length is known as the cosine (cos) of an angle. The ratio of a right triangle's adjacent side's length to its opposite side's length is the angle's tangent (tan).
given
cot + csc(x) (x)
= cos(x)/sin(x) 1/sin(x) (x) [using the csc(x) and cot(x) definitions]
= (cos(x) + 1) / sin (x) [combining the phrases by reducing them to a single value]
The right side of the equation will then be made simpler:
(csc(x) - cot(x)) = 1
= 1 / (1/cos(x)/sin(x) - sin(x)) [using the csc(x) and cot(x) definitions]
= Sin(x) / Cos(x) [using the reciprocal and a denominator that is simpler]
We shall now demonstrate that the left and right sides are equal:
Sine (1 + cos(x)) (x)
= [(1 + cos(x))] / [(1 + sin(x)] *[1 - cos(x)] / (1 - cos(x)] [by adding 1 - cos(x) to the numerator and denominator]
= sin(x) * (1 - cos(x) / (1 - cos2(x)) [reduce the numerator]
= sin2(x)/sin(x)*(1 - cos(x)) [by applying the formula sin2(x) = 1 - cos2(x)]
= Sin(x) / Cos(x) [removing the common sin(x) factor]
As a result, we have demonstrated: 1 / (csc(x) - cot(x)) = csc(x) + cot(x) as the right side of the equation .

PLEASE ANSWER ASAP I MARK BRAINLIEST!!
Answer:
Let's call the number of nuts "n", the number of bolts "b", and the number of screws "s".
From the problem, we know:
s = 3n (Since there are 3 times as many screws as nuts)
b = n + 32 (Since there are 32 more bolts than nuts)
n + s + b = 782 (Since the total number of nuts, screws, and bolts is 782)
Now we can use substitution to solve for one of the variables in terms of the others. Let's solve for "n":
n + 3n + (n + 32) = 782
5n + 32 = 782
5n = 750
n = 150
Now we know there are 150 nuts. We can use this information to find the number of bolts:
b = n + 32
b = 150 + 32
b = 182
Finally, we can use the information we have about the screws to find their number:
s = 3n
s = 3(150)
s = 450
Therefore, there are 450 screws in the box.

Assuming the black and red squares are equally likely and there is no bias in the coin, the probability that it will land heads up on a black square is 1/2, or 50%.
What is probability and why will it be 1/2?Probability is a branch of mathematics that studies the likelihood of a random event occurring. When a coin is tossed into the air, for example, the possible outcomes are Head and Tail.
We will have a probability of 50%; this is because there are two equally likely outcomes when flipping a coin - heads or tails - and each square on the checkerboard has an equal chance of being landed on.

The required values of angles are 1) 90° 2) 180° 3) 45° 4) 135° 5) 135°.
What is angle?
An angle is a figure in Euclidean geometry that is made up of two rays that share a common endpoint, called the vertex of the angle. These rays are called the sides of the angle. The plane containing the rays is where the angles created by two rays are located. Points are additionally shaped by the convergence of two planes. The term for these is dihedral angles.
According to question:We have a circle in which angles are vertically equal.
1) So, ∠AB is 90°.
2) BE is half of the circle,
∠BE is 180°
3) BC is half of quadrant,
∠BC is 45°
4) DF is combined of quadrant and half of quadrant,
∠DF is 90 + 45 = 135°
5) EAC contain half circle and half of quadrant,
∠EAC is 180 + 45 = 135°
Thus, required values of angles are 1) 90° 2) 180° 3) 45° 4) 135° 5) 135°.

Point: (-4,-6), slope: 7/3
Draw a graph
Here is the graph of the point (-4, -6) with a slope of 7/3.
To create the graph, start at the point (-4,-6) and plot it on the coordinate axis. From there, use the slope of 7/3 to find another point on the same line. To do this, you can move 7 units up and 3 units to the right from the point (-4,-6) to get to the point ( -1, -1). Plot this point on the graph as well. Finally, draw a straight line passing through both points to get the line representing the equation of the given point and slope.
