Answer:

3 pounds per month

Step-by-step explanation:

22-4 = 18

18/6=3

Answer:

let dimention of original garden be x

then (x-8)(x-5) = 180

x^2 -13x -140 = 0

(x-20)(x+7)=0

x= 20 or x = -7

x = 20

original area = (20)^2

= 400 m^2

Answer:

50

Step-by-step explanation:

All angles around a circle is 360°

/_ 2 = 130°

/_ 1 = 130° (Vertically opposite angles)

= 130° + 130° = 260°

all angles = 360°

= 360° - 260° = 100°

= 100° ÷ 2

= 50°

= /_ 3 and /_ 4 = 50°

Verification = 130° + 130° + 50° + 50° = 360°

Answer:

Here a = 20,, b= 8

Step-by-step explanation:

Using Pythagoras theorem,

a^2 + 15^2 = 25^2 ,, b^2 + 6^2 =10^2=100

Answer:

a = 20, b = 8

Step-by-step explanation:

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

(1)

a² + 15² = 25²

a² + 225 = 625 ( subtract 225 from both sides )

a² = 400 ( take the square root of both sides )

a = [tex]\sqrt{400}[/tex] = 20

(2)

b² + 6² = 10²

b² + 36 = 100 ( subtract 36 from both sides )

b² = 64 ( take the square root of both sides )

b = [tex]\sqrt{64}[/tex] = 8

Answer:

[tex]12x+8y[/tex]

Step-by-step explanation:

1) Expand by distributing terms.

[tex]4*3x+4*2y[/tex]

2) Simplify 4*3x to 12x.

[tex]12x+4*2y[/tex]

3) Simplify  4*2y to 8y.

[tex]12x+8y[/tex]

Therefor, the answer is 12x + 8y.

Answer:

Answer:

x = 33

Step-by-step explanation:

x - 12 and 2x + 3 form a right angle , then

x - 12 + 2x + 3 = 90

3x - 9 = 90 ( add 9 to both sides )

3x = 99 ( divide both sides by 3 )

x = 33

Answer:

10

Step-by-step explanation:

Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3. Then the correct option is B.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

The slope for account A is calculated as,

m = (504 - 450) / (1 - 0) = (564 - 504) / (2 - 1)

54 ≠ 60

Account A is non-linear. The amount after 3 years will be more than $620 ($564 + $60).

The slope for account B is calculated as,

m = (570 - 550) / (1 - 0) = (590 - 570) / (2 - 1)

20 = 20

Account A is linear. The amount after 3 years will be $610 ($590 + $20).

Answer:

C

Step-by-step explanation:

As x moves towards infinity, the y value is constant, it never changes.

Answer:

The answer is C, it doesn't show a change

1. Yes, angles a and b have a common vertex (starting point) and a common side (the line between angle a and b). They do not overlap.

2. No, angles a and b share a common vertex but not a common side.

3. No. Same as above.

4. Yes, anlges a and b share a common vertex and side.

Answer: C

Answer:

the surface area is 544 square units

Step-by-step explanation:

the tringles first

12 x 8 = 96

base

12 x 14 = 168

sides

10 x 14 x 2 = 280

96 + 168 + 280

im going to break it down

000 + 100 + 200 = 300

90 + 60 + 80 = 230

6 + 8 + 0 = 14

300 + 230 = 530

530 + 14 = 544

The surface area of the triangular prism is equivalent to 330 units square.

A triangular prism is a 3D shape with two identical faces in the shape of a triangle connected by three rectangular faces.

Given is a triangular prism as shown in the image.

We can calculate the surface area of the triangular prism as follows -

A{P} = {2 x A(T)} + {2 x A(R)} + A{B}

A{P} = {2 x 1/2 x 12 x 8} + {2 x 14 x 10} + {14 x 12}

A{P} = 12 x 8 + 2 x 140 + 14 x 12

A[P} = 4{3 x 2} + 2(7 + 6) + 280

A[P} = 24 + 26 + 280

A{P} = 330 units square

Therefore, the surface area of the triangular prism is equivalent to 330 units square.
