Answer:

30 cm

Step-by-step explanation:

The circumference of a circle is

C = 2*pi*r

60pi = 2* pi *r

Divide each side by 2pi

60/2pi = 2 pi r/ 2pi

30 =r

Answer:

Step-by-step explanation:

circumference , c = 60[tex]\pi[/tex] cm

we know circumference of a circle = 2[tex]\pi[/tex]r

ie  2*[tex]\pi[/tex]*r=60[tex]\pi[/tex]

ie   2r=60

radius = 30cm

Answer:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]

Step-by-step explanation:

If we call "x" the number of call minutes used with this plan, the piecewise function used to describe it must represent;

a) a constant value of 29 for any x value smaller than or equal to 250

b) a line with positive slope of 0.35 for the region with x larger than 250. The mathematical representation of such increasing straight line, should be given by a line of slope m = 0.35, and containing the point (250, 29) which is the starting point for this right hand side portion of the domain:

[tex]f(x)=0.35(x-250)+29\\f(x)=0.35 x-87.5+29\\f(x)=0.35 x-58.5[/tex]

So the function should look like:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]

or as shown above, in a more simplified form:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {0.35x-58.5\,\,\,for \,\,x>250}} \right.[/tex]

Answer:

Step-by-step explanation:

3c + 5w = 16

6c + 2w = 22

-6c - 10w = -32

6c  + 2w = 22

-8w = -10

w = 10/8 = 5/4 = $1.25 per lb

3c + 5(1.25) = 16

3c + 6.25 = 16

3c = 9.75

c = $3.25 per lb

Answer:

y+1 = -1(x+10)

Step-by-step explanation:

The point slope equation of a line is

y-y1 = m(x-x1) where m is the slope  and (x1, y1) is a point on the line

y - -1 = -1 (x --10)

y+1 = -1(x+10)

Answer:

2.27 m²

Step-by-step explanation:

The shaded area is the subtraction of the area of an equilateral triangle (with sides = 2 m) to the area of a square (with sides = 2 m)

Area of equilateral triangle = √3/4*a²

where a is the length of the sides of the triangle. Replacing with a = 2

Area of the equilateral triangle = √3/4*2² = √3 m²

Area of the square = a² = 2² = 4 m²

Shaded area = 4 - √3 ≈ 2.27 m²

Answer:

7x - y = 5

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Obtain the equation in point- slope form and rearrange into standard form.

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 7 and (a, b) = (1, 2)

y - 2 = 7(x - 1) ← in point- slope form

y - 2 = 7x - 7 ( subtract y from both sides )

- 2 = 7x - y - 7 ( add 7 to both sides )

5 = 7x - y , that is

7x - y = 5 ← in standard form

Answer:

see explanation

Step-by-step explanation:

Inequalities of the form | x | < a have solutions of the form

- a < x < a

Given

| x - 4 | < 3 , then

- 3 < x - 4 < 3 ( add 4 to the 3 intervals )

1 < x < 7

Thus x > 1 or x < 7

The solution of the given inequality is x < 7 or x > 1.

To solve the inequality Ix - 4| < 3, we can break it down into two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: x - 4 > 0

In this case, we don't need to consider the absolute value because the expression inside it is already positive.

So we have:

x - 4 < 3

Adding 4 to both sides:

x < 3 + 4

x < 7

Case 2: x - 4 < 0

In this case, the expression inside the absolute value is negative, so we need to negate it when removing the absolute value. Therefore, we have:

-(x - 4) < 3

Expanding the negation:

-x + 4 < 3

Subtracting 4 from both sides:

-x < 3 - 4

-x < -1

Dividing both sides by -1 and flipping the inequality sign:

x > 1

Combining the results from both cases, we have the solution:

x < 7 or x > 1

In interval notation, the solution is (-∞, 1) U (7, +∞).

Hence the solution of the given inequality is x < 7 or x > 1.

Answer:

Step-by-step explanation:

[tex]F\left[X] = 5X +7X -2 =12X-2\\[/tex]

[tex]g\left[x] = -2x^2+4x+5 \\[/tex]

[tex]f(x) - g(x) \\= 12x -2 - ( -2x^2+4x+5)\\=12x-2+2x^2-4x-5\\=2x^2 + 8x -7[/tex]

Answer:

2x^2+8x-7

Step-by-step explanation:

Combine like terms 5x+7x in your f(x) equation.  

f(x) = 12x-2 then subtract g(x) from f(x).

12x-2-(-2x^2+4x+5)

Now distribute the negative to everything in the parenthses to change the signs.

12x-2+2x^2-4x-5.

Now, combine like terms.  12x-4x=8x

Combine -2-5=-7

Next, order expression beginning with largest exponent:

Your answer:  2x^2+8x-7.

1 8/40 Simplify to 1 1/5

Step-by-step explanation:

Answer:

Hai

6x=3600

x=600

so tuan collected 600 bottles.

aziz collected 3000 bottles.

5x(aziz)+x(tuan)=3600

good luck (:

Answer:

Step-by-step explanation:

Let x represent the number of bottles Tuan collected. Then 5x is the number Aziz collected. Their total is ...

  x +5x = 3600

  6x = 3600 . . . . . . collect terms

  x = 3600 ÷ 6

  x = 600

Tuan collected 600 bottles.

Answer:The answer would be A. 1 1/5

48/40 = 1 8/40

1 8/40 Simplify to 1  1/5

The distance formula

Step-by-step explanation:

This was kind of vague, but I'll try my best.

You can use the distance formula! It is basically the pythagorean theorem.

Here's the steps,

1. draw a right triangle from the corners. If you have graph paper, this should be relatively easy.

2. locate the hypotenuse, that is the distance.

3. next use the pythagorean theorem/ distance formula (same thing)

4. Except, instead of a and b and c, replace them with

(Change in x)²+(change in y)²= distance²

Now plug in the values
