Answer:

7.8025

Step-by-step explanation:

You get the circumfence formula 2 * pi * r

since you are looking for the radius divide 49/2 then the answer you get divide it by pi and then you have your radius

i hope this helped<33

[I'm using 22/7 as pi in this question, for the sake of convenience, since the value of pi to be used isn't given.]

Circumference = [tex]2\pi r[/tex]

49 = 2 x [tex]\frac{22}{7}[/tex] x r

r = 49 x [tex]\frac{7}{44}[/tex]

r = approx. 7.8 yards

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

Step-by-step explanation:

6.3x103 kg sand x 1x103 g/kg x 1 grain sand/7x10-5 g sand = 9x1010 grains of sand = 90 billion grains of sand.

90 billion grains of sand.

(6.3 x  103kg) (1 x 103g/kg x 1 )

DIVIDED by  7 x 10 - 5 g sand  

= 9 x 1010 grains of sand

Answer:

With that amount of butter she can make 26 pies.

For each pie she spends $1.13625 of butter.

Step-by-step explanation:

We first need to convert the total amount of butter she has from pounds to cups, to do that we need to multiply by 2, since for each pound she has 2 cups of butter, therefore:

butter in cups = 10*2 = 20 cups

Since each pie requires 3/4 cups of butter in order to calculate the number of pies she can make we need to divide the total amount of butter she has by the amount required for each pie. We have:

number of pies = total butter in cups / butter for one pie

number of pies = 20 / (3/4) = 20*(4/3) = 80/3 = 26.667

Since she can't make 0.66 pies, we will need to take only the integer part in consideration, therefore she can make 26 pies.

In order to know the cost for each pie we first need to know the cost for each pound of butter, to calculate that we take the total amount paid by her and divide it by the amount of butter she got.

price of butter per pound = 30.3/10 = 3.03

So each pound of butter costs $3.03 and is equivalent to 2 cups, we can make a rule of three to find the cost for each pie as shown below:

2 cups -> $3.03

3/4 cups -> $x

2/(3/4) = 3.03/x

2*(4/3) = 3.03/x

8/3 = 3.03/x

8x = 9.09

x = 9.09/8 = $1.13625

For each pie she spends $1.13625 of butter.

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.

Answer:

Step-by-step explanation:

- 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:

It 2/5.

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]%.

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:

(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

We get:  (1/6) (π (8 units)² = (4/3) π units², or approximately 33.5 units²

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)
