360 divided by 12 is 30.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

Dividend=360

Answer:

1) 6s + 8

2) 50

Step-by-step explanation:

1)

To find the perimeter, add the lengths of the sides.

perimeter = 3s - 1 + 2s + 5 + s + 4

perimeter = 6s + 8

2)

Replace s with 7 in the perimeter expression.

perimeter = 6(7) + 8

perimeter = 42 + 8

perimeter = 50

Answer: 6s+8

Answer:

see below

Step-by-step explanation:

eq.1      2a   - b + 2c = -8

eq.2            5b  - 3c =  21

eq.3     -7a        -10c = -2

3 equations, 3 unknown.

first step is to eliminate b using eq1 and eq2

2a   - b + 2c = -8 (5)

      5b  - 3c =  21

10a - 5b + 10c = -40

        5b -  3c =  21

10a        + 7c = -21 ------------eq. A

lets solve a using eq. A

10a + 7c = -21

a = (-7c - 21) / 10

now substitute a into eq.3

-7a        -10c = -2

-7(-7c - 21) -10c = -2 distribute

        10

4.9c + 14.7 - 10c = -2  add similar terms

-5.1c = -2 - 14.7  simplify

c = -16.7 / -5.1

c  ≈ 3

solve b using eq. 2 and substitute c.

5b  - 3c =  21

5b = 21 + 3c

5b = 21 + 3(3.2)

b = 30.825 / 5

b ≈ 6

solve a using eq. A

10a + 7c = -21

10a + 7(3.2) = -21

10a = -21 - 22.4

a = -43.4 / 10

a ≈ -4

2(9) - 2(7r) + 8r

18 - 14r + 8r

18 - 6r

Answer:

18 - 6r

Step-by-step explanation:

2(9 - 7r) + 8r

Expand the brackets:

⇒ 2 · 9 - 2 · 7r + 8r

⇒ 18 - 14r + 8r

Combine like terms:

⇒ 18 - 6r

Given that,

A G.P. Bulk bills at $41.20 per consultation, and sees a new patient every 15 minutes for 3 hours.

Solution,

3 hours means 180 minutes

It means that he sees a new patient every 15 minutes for 180 minutes.

No of patients = [tex]\dfrac{180}{15}=12[/tex]

Fees for per consultation is $41.20. Total bill will be :

Bill = $41.20×12

= $494.4

He has not converted 3 hours to minutes. It is the error made by the new employee. He get wrong Medicare bill for the patients.

The distance between the lines with equations -4x + 7y + 9 = 0 and y = 4/7x - 9 is 7.71 units.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The distance between the two straight parallel lines can be found by finding the difference between the y-intercept of the two lines. Therefore, for the two of the given equation, the value of the y-intercept can be written as,

Y-intercept of -4x + 7y + 9 = 0

-4x + 7y + 9 = 0

7y = 4x - 9

y = (4x - 9)/7

y = 4x/7 - 9/7

y-intercept = -9/7

Y-intercept of y = 4/7x - 9

y = 4/7x - 9

y-intercept = -9

Now, the difference distance between the two lines will be,

Distance = Difference between the y-intercept

               = -9 - (-9/7)

               = -9 + 1.2857

               = 7.71

Hence, the distance between the lines with equations -4x + 7y + 9 = 0 and y = 4/7x - 9 is 7.71 units.

Answer:

1107.0213 cm

Step-by-step explanation:

Assuming this gutter is half a cylinder,

Volume of half a cylinder = 0.5(πr²l)²

where, Volume = 20l, π = 3.142, r = 0.5(11.5) and l = ?

But, the other units are in cm while the Volume is in liters, so let's convert the liters to cm³

It would be easier to convert the liters to m³ then to cm³ rather than converting directly. So,

1000 L = 1 m³

     1 L = ?

1 ÷ 1000 = 0.001 m³

      1 m³ = 1,000,000cm³

0.001 m³ = ?

0.001 x 1,000,000 = 1000 cm³

So, if 1 L = 1000 cm³

      20 L = ?

20 x 1000 = 20,000 cm³

Thus, 20,000 = 0.5(3.142 x 0.5(11.5) x l)

20,000 = 0.5(3.142 x 5.75 x l)

20,000 = 18.0665l

Make l the subject and divide both sides by 18.0665

length = 1107.0213 cm

Answer:

72.22

Step-by-step explanation:

C = [tex]\pi \: d[/tex]

3.14×23=72.22

The circumference of a circle whose radius is 11.5 inches.

Thus, option (a) is correct.

Given:

Diameter = 23 inch

So, Radius of circle = diameter/2

                                =23/2

                                = 11.5 inch

Now, the formula for circumference of a circle is

= 2πr

Substituting the value of r= 11.5 into the formula as

= 2 x 3.14 x 11.5

= 72.22 inches

Thus, the circumference of circle is 72.22 inches.

Answer:  -1/3 x -1

Step-by-step explanation:

By doing some stuff, you get the slope of the first line as -1/3. Set up -1/3 x +b and you plug in the coordinates. That makes b= -1. Hope it helps :)

Step-by-step explanation:

length = x

width = 2x-8

b.) to get the area you need to multiply the length and the width.

l×w= area

x(2x-8)

2x^2-8x

c.) 2x^2-8x = 10

subtract 10 both sides

2x^2-8x-10 = 0

2(x^2-4x-5) = 0

2(x-5)(x+1) = 0

x = 5

the area would be 10.
