Answer: 12
Step-by-step explanation:
x/6 = 2
you have to divide x equally into 6 two times to find x you have to
Times the Denominator and the answer (6·2)
which results in being 12
and to check you plug 12 into x and get this 12/6 = 2
6*2 = 12
so 12 was divided 2 times into 6 and you get 2 = 2

Translate the image using the rule down below
By translating the pre-image triangle CRT with this translation rule (x, y) → (x + 2, y - 4), the coordinates of the image triangle C'R'T' are: C' (-2, -2), R' (-3, -5), and T' (3, -3).
What is a translation?In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image or parent function.
Note: Each interval on this graph represents 1 unit.
Next, we would transform triangle CRT by using this translation rule (x, y) → (x + 2, y - 4) to create the vertices of triangle C'R'T' as follows:
(x, y) → (x + 2, y - 4)
Point C (-4, 2) → Point C' = (-4 + 2, 2 - 4) = (-2, -2)
Point R (-5, -1) → Point R' = (-5 + 2, -1 - 4) = (-3, -5)
Point T (1, 1) → Point T' = (1 + 2, 1 - 4) = (3, -3)

Which formula can be used to calculate the horizontal displacement of a horizontally launched projectile? x = vi(cos ) x = vi(sin )t x = ayt x = vxt
To calculate the horizontal displacement of a horizontally launched projectile.
The formula for calculating the horizontal displacement of a horizontally launched projectile is [tex]x = v*t[/tex]
A projectile launched horizontally with a velocity v, at a height y ,travels a horizontal distance x, while falling through a distance y.
The horizontal velocity of a projectile remains constant throughout its motion, in the absence of air resistance. The vertical component of the velocity is under the action of the gravitational force and hence it increases in magnitude as it falls through the height.
The horizontal displacement of the projectile is a uniform motion and it occurs at a constant speed v.
Hence, the horizontal displacement of the projectile is given by the expression.[tex]x = v*t[/tex]
It would help to recreate the problem variables in the math equation editor, or define what you mean by "vi(cos )t" and "[tex]v*t[/tex]". These are somewhat vague descriptions.

which statement is not true about nonresponse issues in sampling? increasing the response rate may not reduce nonresponse bias. response rates themselves do not indicate whether the respondents are representative of the original sample. nonresponse error is one of the most significant problems in survey research. for a given study, if the nonrespondents differ from the respondents on the characteristics of interests, the sample estimates will only be mildly biased.
Non-response bias can occur when subjects who refuse to take part in a study, or who drop out before the study can be completed, are systematically different from those who participate.
What is sampling?A statistical technique called sampling uses a small portion of a larger population to represent the entire population. Sampling is a topic that takes into account the many approaches that might be used to survey a segment of the population and looks for a sample that is most representative of the entire population. The ability of a particular subset of a population's members to be generalized to the entire population is referred to as a sample's "generalizability," or "representativeness." For a highly generalizable outcome,Sampling is a key tool in the scientific method, allowing researchers to provide evidence that generalizable theories are true simply from a sample of specific facts.Hence,Non-response bias can occur when subjects who refuse to take part in a study, or who drop out before the study can be completed, are systematically different from those who participate.

A strait line has a gradient of 3 and passes through (2,10) what’s the equation of the line
I WILL GIVE BRAINILY IF SOLVED IN TJE NEXT 5 MINS (needs to be correct tho)
If a straight line has a gradient of 3 and passes through a point (2, 10), then the equation of the line is [y = (3x + 4)].
As per the question statement, a straight line has a gradient of 3 and passes through a point (2, 10),
And we are required to determine the equation of the above mentioned line.
To answer this question, we need to know the formula to determine the equation of a straight line having a known slope, say "m", and passing through a known point, say (x₁, y₁), which goes as,
[(y - y₁) = {m(x - x₁)]
Here, since our concerned line has a gradient of 3, i.e., (m = 3), and passes through a point (2, 10), i.e., [(x₁, y₁) = (2, 10)], using these values in the above mentioned formula to determine the equation of a straight line having a known slope and passing through a known point, we get,
[(y - 10) = {3(x - 2)}]
Or, [(y - 10) = (3x - 6)]
Or, [y = 3x + (10 - 6)]
Or, [y = (3x + 4)]
That is, the equation of a straight line having a gradient of 3 and passing through a point (2, 10) is [y = (3x + 4)].

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess board. On the second square the King would place two grains of wheat, on the third square, four grains of wheat, and on the fourth square eight grains of wheat. If the amount of wheat is doubled in this way on each of the remaining 30 squares, how many grains of wheat should be placed on square ? Also find the total number of grains of wheat on the board at this time and their total weight in pounds. (Assume that each grain of wheat weighs 1/7000 pound.)
The number of grains on square 13 will be 4096 grains.
How to calculate the number of grain?No. of grains on the first square = 1 = 2^0
No. of grains on the second square = 2 = 1*2 = 2¹
No. of grains on the third square = 4 = 2*2 = 2²
No. of grains on the fourth square = 8 = 2*4 = 2³
From the pattern it could be seen that amount of wheat is doubled for every next square
So, the number of grains in the nth square = 2^n-1
Therefore, No. of grains on 13th square
= 2^13 -1
= 4096

A horse trainer records the distance a horse travels during three different trials.
The horse's average speed = 0.3 kilometers per minute.
Given the following data:
Time 1 = 15 minutes
Time 2 = 30 minutes
Time 3 = 45 minutes
Distance 1 = 4.5 kilometers
Distance 2 = 9.0 kilometers
Distance 3 = 13.5 kilometers
To determine the horse's average speed in kilometers per minute:
First of all, we would find the total time and total distance covered:
For total time:

Two buildings are 18.5 meters apart. The angles of elevation from the top of one building to the top of the other is 18 degrees. If the taller building is 15 meters tall, how tall is the shorter building?
Quick pls In the triangle below, with right angle G, suppose that mZF-(3x-14)° and mZH=(5x-16).
Find the degree measure of each angle in the triangle.
The degree measure of each angle in the triangle are:
F = 31°
G = 90°
H = 59°
How to calculate the angles?It is important to note the following in the triangle:
Sum of all angle in a triangle = 180°
A right angle = 90°
Therefore, since G is a right angle, it's 90°.
H = 5x - 16
F = 3x - 14
The value of x will be found thus:
F + G + H = 180°
3x - 14 + 90° + 5x - 16 = 180
Collect like terms
3x + 5x = 180 + 14 - 90 + 16
8x = 120
Divide
x = 120 / 8
x = 15°
Therefore,
H = 5x - 16
H = 5(15) - 16
H = 75 - 16
H = 59°
F = 3x - 14
F = 3(15) - 14
F = 45 - 14
F = 31°

Evaluate:
Tan(cos^-1(x/4))
The trigonometric function tan(cos⁻¹(x/4)) evaluates to √(16 - x²) / x
To evaluate a trigonometric function?
Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles
Given the trigonometric function tan(cos⁻¹(x/4)) to evaluate:
tan(cos⁻¹(x/4))
Let θ = cos⁻¹(x/4)
Thus, cos θ = (x/4) (remember: cos θ = adjacent/hypotenuse)
We can use this information to draw a right-angled triangle as shown (image attached). Considering the triangle:
4² = x² + y²
y² = 16 - x²
y = √(16 - x²)
That means, the opposite is y = √(16 - x²)
tan θ = y/x = √(16 - x²) / x (Since tan θ = opposite/adjacent)
tan(cos⁻¹(x/4)) = √(16 - x²) / x
Therefore, tan(cos⁻¹(x/4)) evaluates to √(16 - x²) / x
