If tan A=7/12, what is cos A?
Answers
tan(A) = sin(A) / cos(A)
So, dividing both sides by tan(A), we get:
tan(A) = sin(A) / cos(A)
=> cos(A) = sin(A) / tan(A)
=> cos(A) = 1 / (sqrt(1 + tan^2(A)))
Plugging in the value of tan(A) = 7/12:
cos(A) = 1 / (sqrt(1 + (7/12)^2))
=> cos(A) = 1 / (sqrt(1 + 49/144))
=> cos(A) = 1 / (sqrt(196/144))
=> cos(A) = 1 / (sqrt(196/144))
=> cos(A) = 1 / (sqrt(4/3))
=> cos(A) = sqrt(3/4)
So, cos(A) = sqrt(3/4).
what are the factor pairs needed to answer 3z^2 + 26z - 9

daddy
Step-by-step explanation:
hey daddy
Answer:
Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).
Step-by-step explanation:
To factor the quadratic expression 3z^2 + 26z - 9, we need to find two numbers that multiply to give us 3 times -9 = -27, and add up to 26.
One way to do this is to list all the factor pairs of -27 and look for the pair that has a sum of 26:
-27 and 1
-9 and 3
-3 and 9
-1 and 27
We can see that the pair that adds up to 26 is -3 and 9. So we can use these numbers to write the quadratic expression as a product of two binomials:
3z^2 + 26z - 9 = (3z - 1)(z + 9)
Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

What is height of 165 cm?
Answers
The height of 165 cm is equivalent to 1.65 meters or 5 feet 5 inches.
This is a measurement of length or distance that is commonly used to describe the height of a person or object.
To convert centimeters to meters, you can simply divide the number of centimeters by 100. In this case, 165 cm divided by 100 gives you 1.65 meters.
To convert centimeters to feet and inches, you can first divide the number of centimeters by 2.54 to get the number of inches. Then, you can divide the number of inches by 12 to get the number of feet and the remainder will be the number of inches.
In this case, 165 cm divided by 2.54 gives you 64.96 inches. Dividing 64.96 inches by 12 gives you 5 feet with a remainder of 4.96 inches, which can be rounded to 5 inches.
So, the height of 165 cm is equivalent to 1.65 meters or 5 feet 5 inches.

For two adjacent angles x° and (x + 30)° that make up a 90° angle, what is x
Answers
In the given situation, the required value of x for the given pair of adjacent angles is 30°.
What are adjacent angles?When two angles have a similar vertex and side, they are referred to as neighboring angles.
The vertex of an angle is the point at which the rays that make up its sides come to an end.
When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.
The definition of adjacent is next to or nearby.
Two next-door residences are an illustration of proximity.
Typically, we think of those who live on our street as neighbors.
So, we have:
x + x + 30 = 90
Now, solve for x as follows:
x + x + 30 = 90
2x + 30 = 90
2x = 90 - 30
2x = 60
x = 60/2
x = 30
Therefore, in the given situation, the required value of x for the given pair of adjacent angles is 30°.

Find the difference. use your answer in the simplest terms, using the slash ( / ) as the fraction bar.
1/2 - 1/4
Answers
Answer:
1/4
Step-by-step explanation:
You cannot subtract (or add) a fraction with different denominators so first, you need to find a common denominator. You can do this by finding the least common multiple (LCM).
Here the denominators are 2 and 4 so the LCM is 4.
After you find the LCM you need to multiply the denominator by a number that equals the LCM. Then multiply the numerator by that same number.
So convert both 1/2 and 1/4
1/4 x 1/1 = 1/4
1/2 x 2/2 = 2/4
Now we can just subtract the numerator from each other.
2/4 - 1/4 = 1/4
We cannot simplify the difference any more so keep it the same.

What is the perimeter of a regular dodecagon with a side length of 5√6 inches?

C. 60√30 inches
D. 360√2 inches
E. 55√6 inches
Answers
The perimeter of a regular decagon with sides 5√6 is 50√6 ( option A)
What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
The perimeter of a shape is obtained by adding all the sides together.
Therefore, if one side is 5√6 inches, a decagon which is of 10sides will have 5√6 inches at all it's sides because it is a regular polygon.
Therefore P= 5√6 × 10
P = 50√6 inches.
therefore the perimeter of the decagon is 50√6 inches

If you spin the spinner 75 times, how many 2’s? (Note: Spinner has 5 spots ranging from 1-5)
Answers
If you spin the spinner 75 times, the expected number of 2's is 15.
About probabilitySince the spinner has 5 spots ranging from 1-5, the probability of getting a 2 on any given spin is 1/5.
Therefore, if you spin the spinner 75 times, the expected number of 2's is: (1/5) * 75 = 15
So, if you spin the spinner 75 times, you can expect to get 15 2's.
Probability itself has a number from 0 to 1.
The probability value is 0 (zero) for an event that is impossible or unlikely to occur, for example, cows laying eggs.

How would you make an equation of a linear function if it starts at 1127 and goes up 92 every hour
Answers
The solution is given below.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
Consider that on a coordinate plane-xy, the x-values increase from left to right, and y-values increase from bottom to up.
Given that the linear graph passes through (1,1).
It is given that the graph goes 3 units up for every 2 units right. This can also be understood as the graph goes 3 units down for every 2 units left.
From the point (1,1), the x-value corresponding to 2 units left is given by,
x=1-2
x= -1
Similarly, from the point (1,1), the y-value corresponding to 3 units down is given by,
y = 1 - 3
y= -2
So the point (-1,-2) must also lie on the same linear graph.
Therefore, option (b) is the correct choice.

(−1.5, 0.25)
(−0.5, 0.75)
(1.5, 0.25)
(−2.5, 1.5)
Answers
Answer:
To approximate the solution to the system of equations, we need to find the point where the two lines intersect. From the second equation, we know that y = (1/2)x + 1. Substituting this expression for y into the first equation gives:
3x + 2[(1/2)x + 1] = -4
Simplifying and solving for x, we get:
3x + x + 2 = -4
4x = -6
x = -1.5
Substituting this value of x back into the second equation gives:
y = (1/2)(-1.5) + 1 = 0.25
Therefore, the solution to the system of equations is approximately (-1.5, 0.25).
So the answer is (−1.5, 0.25).

How to find the perimeter of figures?To find the perimeter of four-sided figures, we just have to add the length of their sides as shown below:
16ft + 16ft + 10ft + 10ft = 52ft7ft + 7ft + 7ft + 7ft = 28ftTo find the area of the triangle we must add its sides, in this case it is a triangle that has all the sides equal so it would be like this:
2ft + 2ft + 2ft = 6ft
Finally, the perimeter of the circle is calculated by multiplying 2 * number pi * radius. So the operation would look like this:
