tan∅ = opposite over adjacentStep-by-step explanation:
Step 1: Set up equation
tan55° = 19/x
Step 2: Solve for x
Multiply x on both sides: xtan55° = 19Divide tan55° on both sides: x = 19/tan55°Evaluate: x = 13.3039Round: x ≈ 13.3And we have our final answer!
Answer:
13.3
Step-by-step explanation:
This is trigonometry
So for this one, we use a basic ratio. We need to use 19 and 55 degrees for the answer. We are given that the leg adjacent to the 55-degree angle is x and the opposite leg to the 55-degree angle is 19.
So we use tangent(opposite leg/adjacent leg) for this (TOA of SOH CAH TOA)
tan(55 degrees)=19/x
SO then solve for x and then evaluate using a scientific calculator and you should get 13.30394322

share 126 in the ratio 2:5
Answer:
first share 2x=36
Second share=5x=90
Step-by-step explanation:
Ratio 2:5
Share=126
Let first share=2x
Second share=5x
So 2x+5x=126
7x=126
X=126/7
X=18
So first share 2x=36
Second share=5x=90

Help plz with this math problem. I’m so confused
Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.
From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).
The equation to find the slope is:
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's substitute in our values:
m = [tex]\frac{-2 - -4}{6 - 3}[/tex]
Remember that two negatives make a positive, let's solve for m:
m = [tex]\frac{2}{3}[/tex]
Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).
Therefore we can determine that b = -6.
Let's substitute our value for m and our value for b into the slope-intercept formula:
y = mx + b
y = [tex]\frac{2}{3}[/tex]x + -6
There's your final answer! I hope this helps, have a great night. :)

A math quiz has 10 questions and is scored out of 100. Each question is worth the same. The function S(q) represents the quiz score, S, in terms of the number of correctly answered questions, q.
Determine whether each statement below is true or false. Select True or False for each statement
Statements are;
1) S(q) represents a quantity that changes at a constant rate per unit interval.
2) S(q) represents a quantity that changes at a constant percent rate per unit interval
3) S(q) represents a linear function
4) S(q) represents an exponential function.
Answer:
Statements 1 & 3 are true while statements 2 & 4 are false
Step-by-step explanation:
We are told that S(q) is a function that represents the quiz score, S, in terms of the number of correctly answered questions, q.
Statement 1 is true because the quiz score(S(q)) changes at a constant rate per unit questions answered since the math quiz has 10 questions and is scored out of 100
Statement 2 is false because S(q) is not expressed as a percentage rate.
Statement 3 is correct because S(q) function is a straight linear functional relationship where it directly depends on the number of correctly answered questions(q)
Statement 4 is false because the relationship is not expressed in exponential form but as a direct linear relationship.
The function S(q) is an illustration of a linear function.
The true statements are:
a) S(q) represents a quantity that changes at a constant rate per unit interval. c) S(q) represents a linear functionThe false statements are:
b) S(q) represents a quantity that changes at a constant percent rate per unit interval d) S(q) represents an exponential function.
From the question, we understand that:
S(q) represents the quiz score in terms of the number of correct answers
This means that:
As the correct answers increases or decreases, the value of s(q) changes at a constant interval
Functions that have such behavior are linear functions because they change at a constant rate
Hence, (a) and (c) are true, while (b) and (d) are false.

Several paint mixtures are made by mixing blue paint and white paint. Paint Colors Blue Paint White Paint Mixture A 5 cups 12 cups Mixture B 6 cups 6 cups Mixture C 4 cups 12 cups Mixture D 5 cups 6 cups Which mixture has the lowest ratio of blue paint to white paint? mixture A mixture B mixture C mixture D
Answer:
The mixture C is the correct option
Step-by-step explanation:
According to the given scenario, the calculation is as follows:
For Mixture A
Blue Paint - 5 cups
White Paint - 12 cups
The ratio between them is 5:12
For Mixture B
Blue Paint - 6 cups
White Paint - 6 cups
The ratio between them is 6:6 = 12:12
It came by multiply the numerator and denominator by 12
For Mixture C
Blue Paint - 4 cups
White Paint - 12 cups
The ratio between them is 4:12
For Mixture D
Blue Paint - 5 cups
White Paint - 6 cups
The ratio between them is 5:6 = 10:12
It came by multiply the numerator and denominator by 12
As it can be seen that in all four mixtures the denominator is the same so for calculating the lowest ratio we have to see the small value in the numerator
As it can be seen that there is a small value of 4
hence, the mixture C is the correct option
Answer:
C mixture

a subject, a verb, and a complete thought
a verb and a complete thought

Step-by-step explanation:
A subject, a verb, and a complete thought
Answer: A subject, a verb, and a complete thought.
Step-by-step explanation:
Independent clauses have three components:
They have a subject - they tell the reader what the sentence is about.They have an action or predicate - they tell the reader what the subject is doing.They express a complete thought - something happened or was said.Select all the values that are equivalent to the given expression. Express your answer in scientific notation.
(9.6 X 103) X (6.7 X 10)
6.432 X 105
6.432 X 106
64.32 x 105
64.32 X 106
(9.6 X 6.7) X (103 X 10)
the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.
Which are the values equivalent to the given expression?Here we start with the expression:
(9.6*10³)*(6.7*10)
Where both numbers are in scientific notation, notice that we can write that product as:
(9.6*10³)*(6.7*10) = (9.6*6.7)*(10³*10) = 64.32*10⁴
Now, remember that in scientific notation, we only can have a single digit in the left of the decimal point, so we can rewrite:
64.32*10⁴ = 6.432*10⁵
So the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.

find the volume of the cone with radius 35dm and slant height 37dm
Answer:
Volume of cone is: 47464.23 dm³
Step-by-step explanation:
We are given:
Radius of cone r = 35 dm
Slant Height of cone h = 37 dm
We need to find Volume of the cone.
The formula used to find Volume is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]
Putting values and finding volume:
[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14*(35)^2 *\frac{37}{3}\\Volume=47464.23\ dm^3[/tex]
So, volume of cone is: 47464.23 dm³
