two complementary angles are in a ratio of $3:2$. what is the measure, in degrees, of the smaller angle?
The measure of the smaller angle of the complementary angles is: 36 degrees.
What are Complementary Angles?If the sum of two angles equals 90 degrees, then they are complementary angles.
Given that the ratio of two complementary angles is 3:2, therefor:
3x + 2x = 90
5x = 90
5x/5 = 90/5
x = 18
The smaller angle = 2x = 2(18) = 36 degrees.
The larger angle = 3x = 3(18) = 54 degrees.
Therefore, the measure of the smaller angle of the complementary angles is: 36 degrees.

Find the degree measure of each angle in the triangle
Answer:
gooddddd luuuuuuuccccccckkkkk
Answer:
<K = 55 <L = 55 <M = 70
Step-by-step explanation:
As it is an isosceles triangle, Two sides of the triangle will be equal and their angles will be equal too.
L and K are both = (4x + 3)
All angles in a triangle add up to 180
(4x + 3) + (4x + 3) + (5x + 5) = 180
4x + 3 + 4x + 3 + 5x + 5 = 180
13x + 11 = 180
13x = 180 - 11
13x = 169
x = 169/13
x = 13
<K = 4x + 3 = 4(13) + 3 = 55
<L = 4x + 3 = 4(13) + 3 = 55
<M = 5x + 5 = 5(13) + 5 = 70

Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers.
Intervals can be classified based on the numbers the set comprises. Some sets include the endpoints specified in the notation, while some might partially or not include the endpoints. In general, there are three types of intervals given as,
open interval shown by round brackets.close interval shown by square brackets.half-open interval shown by mixture of round and square brackets.For the given graph we can conclude the interval one by one.
For the first blank {-3 if x ∈ [-2,-5]}
For the second blank {-2 if x ∈ (-2,3]}
For the third blank {3 if x ∈ (3,4]}
Therefore, {-3 if x ∈ [-2,-5]}, {-2 if x ∈ (-2,3]} and {3 if x ∈ (3,4]} are the required answer for the function f(x).

Given the rule what is the new coordinate? Show all of your work.
Rule: (x, y) → (x - 7.5, y + 6.8)
Original coordinate: (5, 3)
Using translation concepts, the new coordinates are given as follows:
(-2.5, 9.8).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.
For this problem, the rule is given as follows:
(x, y) → (x - 7.5, y + 6.8)
This means that the figure is shifted:
7.5 units left.6.8 units up.The original coordinate is given by:
(5,3), meaning that x = 5 and y = 3.
Applying the rule, we have tat:
5 - 7.5 = -2.5.3 + 6.8 = 9.8.Hence the new coordinates are given as follows:
(-2.5, 9.8).

amelia is documenting the height of sunflower plants each week. she has determined the function to be f(x)
According to the given statement the correct option is: D.
Domain, nonnegative values; range, values greater than 3.
How do we define range?The difference between the greatest and lowest values inside one set of integers is known as the range. Subtract the smallest from the greatest value in the set to determine range.
According to the given information:f(x) = 3x + 3
where f(x) is the plant's height and x is the passage of time.
The set of input values is known as the domain and the collection of output values is known as the range.
Because the value of time cannot be negative, the domain has non-negative values.
The lowest possible value of x is 0. Replace x=0 in the provided function.
f(x) = 3x + 3
f(0) = 3(0) + 3
= 3
At x=0, f(x) has a minimum value of 3, or 3. As x increases, function's value rises. Range thus refers to values greater or equal to 3.

What is the frequency of the sound? assume vsoundvsoundv_sound =340 m/s=340 m/s .
According to the given statement the frequency of the sound = 693.87h2b.
What is frequency?The frequency of a repeated event is its number of instances per unit of time. In certain cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively. One hertz (Hz) equals one (event) per second, which is how frequencies is expressed. Because it reflects the duration of time for one cycle of a recurring occurrence, the period is the opposite of the frequency. For example, the period, T, of a heart beating at such a frequency of 120 times per minute (2 hertz), is equivalent to 0.5 seconds (60 seconds divided by 120 beats).

Conclusions concerning cause-and-effect relationships are only possible when the method is used by Experimental.
Cause and effect relationship is the concept that states about happening of a particular event causes another event to take place. Cause is the action that makes occurrence of effect. Cause is the reason because of which a event happens and effect is the result of that.
Conducting an experiment can clarify the concept to make it more understandable as conduction the experiment is the cause and the outcome is the effect caused due to experiment.
Other options are not appropriate as co-relational research measures two factors to understand relation without experimenting. Naturalistic observation is observing the happening of the natural surrounding and survey is recording the happening or event. Thus, the correct option is option(d).
The primary reason descriptive/correlational research cannot determine conclusively that variables have a cause-and-effect relationship is because in conducting researchThe researcher can't control occasions or control factors. A correlational report is a quantitative strategy for the look into in which you have at least 2 quantitative factors from a similar gathering of subjects, and you are attempting to decide whether there is a connection between the 2 factors.

x= -136 and x = 80
x=-112 and x = 80
x= -80 and x = 80
Answer:
x = -136 and x = 80
Step-by-step explanation:
|(1/4)x +7| - 3 = 24
|(1/4)x + 7| = 27 (transpose 3 and it becomes positive)
now:
(1/4)x + 7 = 27 (first solution)
(1/4)x = 20
x/4 = 20
x = 20×4
x = 80
(1/4)x + 7 = -27 (second solution)
(1/4)x = -34
x/4 = -34
x = -34×4

if dr. lintz tried to make inferences about the outcomes of individuals based on her data of state legislatures, what mistake would she be making?
A unit of analysis is merely the entity under investigation. This is generally individuals but in case of Dr. Lintz, it really is state legislatures. The variables record information about the legislative bodies themselves, rather than the individuals who make up those bodies.
What is state legislatures?A state legislature is a broad term that refers to the legislative body in any of the 50 states in the United States. The formal name differs from one state to the next.
Some key features regarding the state legislatures are-
Every state (except Nebraska) has a bicameral legislature, which means the legislature is divided into two separate legislative chambers (or "houses"); Nebraska does have a unicameral, or one-chamber legislature. The smaller chamber is called the "Senate" in all bicameral legislatures and is commonly referred to as the "upper house." The smaller chamber generally, but not always, has the exclusive power to approve appointments made by the governor and to attempt articles of impeachment.To know more about the state legislatures, here

The result of evaluating the expression r w-6 is equal to -12.
To evaluate an expression is a term used in maths that generally means to come up with a solution to an equation and if it is not possible then reduce it to a smaller equation by exchanging the variables with the given numerical values.
We can evaluate the given expression as follows:
Since r = 3 and w = -2, we can substitute r and w in the expression, r w-6, with 3 and -2 respectively.
r w - 6 = 3 (-2) - 6
3 (-2) - 6 = -6 -6 = -12.

Discount rate = 30 %
Let the discounted price at which her friend bought the t - shirt be x.
So, we get that:
x = $ 25 - 30 % of $ 25
x = $ 25 - 30 / 100 × 25
