Answer:

$ 1508.57 and please give brainliest

Step-by-step explanation:

The road around the park = 3 m wide,

and the circumference of the park = 132 m,

We have to find the cost of fencing

the outer boundary,

the rate = $10 per m

Step-by-step explanation:

As we know that the circumference

of a circle = 2 × 22÷7 × radius

2 × 22÷7 × radius = 132 m,

44 × radius = 132 m × 7,

44 × radius = 924 m,

radius = 924 ÷ 44 m

So, radius = 21 m ( smaller circle )

radius = 21 m + 3 m ( larger circle )

= 24 m

Usually, we fence on the borders means it's

the circumference of the larger circle

= 2 × 22÷7 × radius

= 44÷7 × 24 m

= 1056÷7 m

= 150.85 m

cost of fencing = $ 10/m

total cost = 150.85 × $ 10

= $ 1508.57

-Chetan K

Answer:

7 words per minute

Step-by-step explanation:

1. To find the unit rate (words per minutes), let's set up two ratios:

2. Now, let's solve for x to find how many words she can type per minute.

Step 1: Cross-multiply.

Step 2: Divide both sides by 9.

Therefore, Christine can type 7 words per minute.

Answer:

( 5, 3 )

Step-by-step explanation:

I imagine you plug in the given ordered pair to the rule:

( x - 3, y + 9 )

( 2 - 3, 12 + 9 )   ( - is the same as going to the right, so it basically adds ).

                         ( + is the same as going to the right, so it basically subtracts ).

Answer:

Jerry is 11.75 years

Step-by-step explanation:

Let us first set up an equation

Let jerry's age be x

4x - 11 = 36 (equation set)

Now we need to slove the equation and find the value of x that is Jerry's age

4x - 11 = 36

Transpose

4x = 36 + 11

4x = 47

x = 47 ÷ 4

x = 11.75 years

Jerry is 11.75 years

Answer:

using the formula( y2-y1/x2-x1 = m)

m= slope

9 - (-2)/-9 -2 =m

11/ -11 = m

m= -1( slope)

since m is also = y- y1/ x-x1

y - (-2)/ x- 2 = -1= y +2 / x -2 = -1 (cross multipy)

-1 (x -2) = y +2

-x +2 = y + 2

-x -y = 2 -2

-x - y = 0(multiply both sides by -1)

x + y = 0

Answer:

y=2x^2+4x−16

Step-by-step explanation:

Assume that the equation of the parabola is y=ax2+bx+c.

Since the parabola passes through the point (−4,0), then 0=16a−4b+c.

Since the parabola passes through the point (2,0), then 0=4a+2b+c.

Since the parabola passes through the point (1,−10), then −10=a+b+c. Thus, we have obtained the following system:

Solving it, we get that a=2, b=4, c=−16. Thus, the equation of the parabola is y=2x^2+4x−16.

The equation of a parabola is  y = -x² + x + 4 with x-intercepts at (-4,0) and (2,0) that passes through the point (1,-10).

A parabola can be represented by the equation:

y = ax² + bx + c

To find the equation of a parabola that has x-intercepts at (-4,0) and (2,0), we can set y equal to 0 and solve for x to find the x-intercepts:

0 = a(-4)² + b(-4) + c

0 = a(2)² + b(2) + c

Solving these equations for a and c gives us:

c = b(-4)

c = -2b

The parabola passes through the point (1,-10), we can substitute the values of x and y into the equation to solve for b:

-10 = a(1)² + b(1) + (-2b)

-10 = a + b - 2b

-10 = a - b

Substituting c = b(-4) into the equation gives us:

y = a x² + b x + b(-4)

Substituting a = -b and solving for b gives us:

y = (-b) x² + b x + b(-4)

y = -b(x² - x - 4)

Since the x-intercepts are at (-4,0) and (2,0), the coefficient of x², which is -b, must be positive. Therefore, we can set b = 1 to get the equation of the parabola:

y = -(1)(x² - x - 4)

y = -x² + x + 4

Thus, the equation of a parabola is y = -x² + x + 4.

Answer:

A*B*C= 28

Step-by-step explanation:

A+B+C=20

1. A = 4(B+C)

2. B = 7C

3. C = C

----------------------

1.

A = 4( 7C + C )

A=4(8C)

A= 32C

---------------------

A+B+C=20

32C + 7C + C = 20

40C = 20

C = 20/40

C = 1/2

------------------------

A= 32(1/2) = 32/2 = 16

B= 7(1/2) = 7/2

C= 1/2

A*B*C = 16 * 7/2 * 1/2

A*B*C=  28

Answer:

D) 22

Step-by-step explanation:

B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.

So that means:

3x - 14 = x + 10

Now solve this equation.

3x - 14 = x + 10

+14. +14

3x = x + 24

-x

2x = 24

/2. /2

X = 12.

Now we know the value of x, insert the value into x + 10.

12 + 10 = 22

The answer is 22

Answer:

B) 12

Step-by-step explanation:

Because,

3x - 14 = x + 10

3x - x = 10 + 14

2x = 24

x = 12

Volume of a cube = l³

                              = (11 in)³

                              = 1331 in³

Surface area of cube = 6a²

                                   = 6 (11 in)²

                                   = 726 in²
