The circumference of a circle is 12πcm. How do you find the a) Diameter: b) Radius: c) Area of the circle in terms of π?

Answer: 2/3

Step-by-step explanation:

First you multiply both numerators which equals 8

Then, you multiply the denomerators which is 24

This gives you 8/24

Since both 8 and 24 are divisible by 8, you divide them by 8 and you get 1/3

Since two negative numbers equal a positive one, the answer is positive

Based on the information we can infer that 25 km is equivalent to 7.5 cm on the map.

To find the relationship between centimeters and kilometers on the map we must take into account the following information:

3cm = 10km

According to the above, we must make a rule of three to find the equivalence of kilometers. Below is the procedure:

According to the above, 7.5 centimeters would represent the 25 kilometers distance on the map.

The correct grouping of the trinomial "-10x² + 13x + 3" is option 4, (-10x² + 0x) + (13x + 3).

To find the correct grouping, we need to factor out the greatest common factor from the first two terms, -10x² + 13x.

The greatest common factor of -10x² and 13x is -x². So, we can factor out -x² and get:

-x² * (10 - 13/x) + 3 = (-x² * 10) + (13/x - x²) + 3 = (-10x² + 7x) + (6x + 3)

Therefore, choice 3 is the correct grouping of the trinomial -10x² + 13x + 3.

Answer:

343 meters per second (3 sf)

Step-by-step explanation:

1236km/h is basically 1236km per hour.

1km = 1000 meters

1h = 60 minutes

1m = 60 seconds

Using these rules, we can convert the kilometers and hour to meters and minutes and then to seconds.

---

1236km = 1236*1000

             = 1 236 000m

---

1h --> 1 236 000m

60m --> 1 236 000m

1m --> 1 236 000/60 = 20 600m

60s --> 20 600m

1s --> 20 600/60 = 343m (3 sf)

There are 343 (3 sf) meters per second.

A better score is the SAT score of 2100 which has an average of 1500 with an SD of 325.

- SAT score of 2100

Now, According to the question:

"Information available from the question"

An ACT score of 28 or a combined SAT score of 2100 when

ACT: μ = 21 and σ = 5;

SAT: μ = 1500 and σ = 325

In order to determine which is a better score, we compare the scores in standard deviation units.

We can convert the score to standard deviation units by subtracting the mean and dividing by the standard deviation.

ACT: (28-21)/5 = 1.2

SAT: (2100-1500)/325 = 1.38

As we see SAT score is better than ACT score as it is 1.38 standard deviation units above the mean, while the ACT score is only 1.2 standard deviation units above the mean.

Hence, SAT score of 2100

The length of the fabric which Brandon formed a rectangle, is 11 inches.

To find the length of the fabric, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the length of the fabric is one of the other two sides, and the diagonal cut is the hypotenuse. So, we can write the equation:

[tex]L^2 + 5^2 = 13^2[/tex]

where L is the length of the fabric.

Solving for L, we get:

The solution to the system of equations is: D. (-4, -7).

To solve the system of equations, y = (3/2)x - 1 and y = 3x + 5, you can set the two equations equal to each other and solve for one of the variables. For example, setting the two equations equal to each other:

(3/2)x - 1 = 3x + 5

Then you can solve for x by isolating it on one side of the equation:

(3/2)x - 3x = 5 + 1

-5x/2 = 6

x = -4

Now that you know the value of x, you can substitute it back into one of the equations to find the value of y:

y = (3/2)(-4) - 1 = -6 - 1 = -7

The missing entries for f(x) are 20, 30, and 40, and the missing entries for g(x) are 40, 80, and 160.

The missing entries for f(x) can be found by knowing that f is a linear function and using the values given. A linear function has the form f(x) = ax + b, where a is the slope and b is the y-intercept. Since f(0) = 10 and f(1) = 20, we can use these two points to find a and b.

Putting x = 0 in the equation, we get:

f(0) = 10 = a(0) + b

Putting x = 1 in the equation, we get:

f(1) = 20 = a(1) + b

Solving these two equations simultaneously, we find:

a = 10

b = 0

So, the equation for f is:

f(x) = 10x + 0 = 10x

Using this equation, we can find the missing entries for f(x) in the table:

f(2) = 10x = 10(2) = 20

f(3) = 10x = 10(3) = 30

f(4) = 10x = 10(4) = 40

So the missing entries for f(x) are 20, 30, and 40.

To find the missing entries for g(x), we need to know the form of the exponential function g. A common form for exponential functions is g(x) = ab^x, where a is the y-intercept and b is the growth factor. Since g(0) = 10 and g(1) = 20, we can use these two points to find a and b.

Putting x = 0 in the equation, we get:

g(0) = 10 = a(1)^0 = a

So, a = 10.

Putting x = 1 in the equation, we get:

g(1) = 20 = 10b

Solving for b, we find:

b = 2

So, the equation for g is:

g(x) = 10(2^x)

Using this equation, we can find the missing entries for g(x) in the table:

g(2) = 10(2^2) = 10(4) = 40

g(3) = 10(2^3) = 10(8) = 80

g(4) = 10(2^4) = 10(16) = 160

So the missing entries for g(x) are 40, 80, and 160.

The surface area of the pyramid is A = 386.24 inches²

The total surface area is the summation of the areas of the base and the three other sides. A = B + ( 1/2 ) ( P x h ), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid

Surface Area of Pyramid = B + ( 1/2 ) ( P x h )

Given data ,

Let the surface area of hexagonal pyramid be represented as A

Surface area of hexagonal pyramid = Area of base + area of lateral surface

Area of the base = 166.3 inches²

Now , the Area of the lateral surface = 3a √ ( h² + ( 3a²/4 ) )

where a = 8 inches

h = 6 inches

Substituting the values in the equation , we get

Area of the lateral surface = ( 3 x 8 ) √ ( 36 + ( 3 x 64 / 4 ) )

On simplifying the equation , we get

Area of the lateral surface = 219.96 inches²

So , Surface area of hexagonal pyramid = Area of base + area of lateral surface

Surface area of hexagonal pyramid A = 166.3 inches² + 219.96 inches²

Surface area of hexagonal pyramid A = 386.24 inches²

Hence , the surface area of hexagonal pyramid is 386.24 inches²
