Simplify the square root of 7 divided by square root 27

Answer:

The ferris wheel travelled 434.717 ft.

Step-by-step explanation:

Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:

radius = height/2 = 246/2 = 123 ft

The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:

length = r*(angle in radians)

length = 123*(9pi/8)

length = 434.717 ft

The ferris wheel travelled 434.717 ft.

Step-by-step explanation:

Answer: y = (1/2)*x - 1

Step-by-step explanation:

a linear relationship is something like:

y = a*x  + b, lets find the values of a and b.

We have that the output (y) must be 1 less than half of the imput (x), then our relation is:

y = (1/2)*x - 1

Answer:

f(x) = -2x + 8, x < 2

g(x) = 2x, x 》2

Step-by-step explanation:

|x - 2| is:

x - 2, for x 》2

-x + 2, for x < 2

For x < 2,

f(x) = 2(-x + 2) + 4

f(x) = -2x + 8

For x 》2,

g(x) = 2(x - 2) + 4

g(x) = 2x

The two linear functions for the given mode function y = 2|x - 2| + 4 will be y = -2x + 8 and y = 2x.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

As per the given mode function,

y = 2|x - 2| + 4

For x < 2 , |x - 2| = -(x - 2)

y = -2(x - 2) + 4

y = -2x + 4 + 4

y = -2x + 8

For x > 2, |x - 2| = x - 2

y = 2(x - 2) + 4

y = 2x - 4 + 4

y = 2x

Hence "The two linear functions for the given mode function y = 2|x - 2| + 4 will be y = -2x + 8 and y = 2x".

Answer:

Last year we had M students.

This year we have N students.

Now, the question ask "by what percentage the number of students grow".

So we are considerating a growth, this means that we must think that M as the 100%.

Then we have that N - M is the difference between the students of last year and this year.

this means that this year we have N - M more students that last year, so the percentage of growth is:

((N - M)/M)*100%

Now you need to replace the values for N and M.

You also can notice that if N is smaller than M, you will have a negative percentage, this means that instead of a growth, we have a decrease in the number of students.

Step-by-step explanation:

8x6=48

48 divided by 2=24

8x4=32

4x6=24

add them all together so 48+40+32+24=144

The triangular prism is a 3-d shape, and the total surface area of the triangular prism is 144 cm²

The surface area of a triangular prism is:

Area = bh + (b + s₁ + s₂) * l

The parameters in the triangular prism are:

So, we have:

Area = 8 * 6 + (8 + 10 + 6) * 4

Evaluate the sum of product

Area = 144

Hence, the total surface area of the triangular prism is 144 cm²

Answer:

33.4% of 104 is equal to 34.736

Answer:

-3 is the coefficient of x here

Step-by-step explanation:

The first thing to do here is to open the brackets.

(x-5)(x + 2) = x(x + 2)-5(x + 2)

x^2 + 2x -5x -10

x^2 -3x -10

When we say the coefficient of x, we mean the value by which x only is multiplied by in the equation. That would be -3

This must not be confused with the coefficient of x^2 which is entirely different from the coefficient of x

Answer:

(6,1)

Step-by-step explanation:

Just look for the terms with x and y in them. Divide their coefficients by two, and multiply by -1. And then put them in an ordered pair.

So in this case, -12x --> 6 and -2y --> 1

Obviously the more orthodox way would be to actually complete the square, but I'm lazy, this way is faster, and since this seems to be multiple choice, as long as you have the correct answer, it shouldn't matter.

The required centre will be at (6,1)

The standard equation of circle is expressed as:

x^2+y^2+2gx+2fy+c = 0

where (-g, -f) is the centre of the circle

Given the equation x^2 + y^2 – 12x – 2y + 12 = 0

Compare with the general to have;

2gx = -12x

g = -6

2fy = -2y

y = -1

Since centre is at (-g, -f), hence the required centre will be at (6,1)

Answer:

Step-by-step explanation:

Just did the question :)

The experimental probability of flipping a head after five flips of a coin can be calculated by finding the ratio of the number of times a head appears to the total number of flips.

In this case, since there are two possible outcomes - a head or a tail - the total number of flips is five. Let's say, after five flips, a head appears three times. The experimental probability of flipping a head would be calculated as 3 (number of heads) divided by 5 (total number of flips), which equals 0.6.  

Therefore, the experimental probability of flipping a head after five flips of the coin is [tex]0.6, or 60[/tex] %. It is important to note that the experimental probability may not accurately represent the theoretical probability, as it is based on a limited number of trials. The theoretical probability of flipping a head is 1/2, which is [tex]0.5 or 50[/tex]%.

Step-by-step explanation:

The IQR is quartile 3 - quartile 1. First, we need to find the mean of the dataset, which is 50 -- the fifth number. Then, the median of the dataset on the left of the fifth number is the first quartile, and the median of the dataset on the right is the third. We get Q1 to then be halfway between 30 and 50, or 40, and Q3 to be halfway between 56 and n, so Q3 = (56+n)/2. Since we need Q3-Q1=27, or (56+n)/2-40=27, we have (56+n)/2=67 and 56+n=134, so n = 134-56=78

- 1.4 < h + 1.1

      Solve for H. Get H by itself by subtracting 1.1 on both sides of the equation.

-1.4 - 1.1 = - 2.5

-2.5 < h

       _

Answer:  The height is 15 cm.

Step-by-step explanation:

We have to know the can is in a shape like a cylinder so  we will use the volume of a cylinder formula to find the height.Which is  πr^2*h

We have to know  8 is the diameter so the the radius is 4.

3.14 * 4^2 * h = 753.6

3.14 * 16 * h = 753.6

50.24 * h = 753.6

Divide 753.6 by 50.24 to find the height

The height is 15.

Answer:

(4/3) π units²  or  (b):  33.5 units²

Step-by-step explanation:

The area of a sector of a circle of radius r and central angle Ф is a fraction of the total area of the circle:  (Ф/[2π]) * πr².

Here we find the area of the circle to be A = π (8 units)².

                                                    60

Multiply that by the fraction  ------------- , or 1/6

                                                    360
