A vegetable garden with an area of 200 square feet is to be fertilized. If the length of the garden is 1 foot less than three times the width, find the dimensions of the garden. Please show work.

Answers

Answer:

Dimensions of the garden are 24 feet by 8.33 feet.

Step-by-step explanation:

Let the dimensions of the vegetable garden is length = l and width = w foot

Area of the vegetable garden = 200 square feet

Since length of the garden is 1 foot less than the 3 times the width.

l = 3w - 1

Area of the garden = w × l = 200

w(3w - 1) = 200

3w² - w = 200

3w² - w - 200 = 0

By quadratic formula

w = $\frac{1\pm \sqrt{1^(2)+2400}}{6}$

= $(1\pm √(2401))/(6)$

= $(1\pm 49)/(6)$

w = -8 or 8.33 foot

Since dimensions can not be negative therefore, width of the garden will be 8.33 foot

Since l = 3w - 1

= 3×8.33 - 1

= 25 - 1

= 24

Dimensions of the garden are 24 feet by 8.33 feet

Ok so I like to go in steps with these questions- first draw a picture and identify your variables.

W=width
L= 3w-1

Now we know that length times width gets us area so we plug in our variables into the area equation.

200 = w(3w-1)

When you foil that equation you end up with a quadratic : 3w^2-w-200 = 0

Either factor that or use the quadratic formula to get
w= 8.33 and w= -8

Since you can't have a negative dimension you need to use 8.33 and plug it back into your length equation.

Final answer:

w= 8.33ft
l= 23.99ft

*Now I simplified the decimals a little bit so you end up with 199.8ft^2 for the area so just add a few decimals on here and there*

In the diagram, what is the measures of angle 1?A.) 45°

B.) 135°

C.) 15°

D.) 125°

Answers

Answer:

The correct option is A.

Step-by-step explanation:

Line A and B are parallel lines.

$\angle 1=3x$ ....(1) (Alternate exterior angles)

$\angle 1+9x=180$ (Supplementary angles)

$3x+9x=180$

$12x=180$

$x=15$

The value of x is 15.

Put this value in equation (1).

$\angle 1=3* 15=45$

Therefore measures of angle 1 is 45° and option A is correct.

Options are: f(x) = 2x - 1 , f(x) = 2x - 7 , f(x) = x - 6 , f(x) = 1 - x , None of the choices are correct.

Answers

Answer:

f(x) = 2x - 7

Step-by-step explanation:

Plug in the numbers on the right and see what answer is right

f(x) = 2x(1) - 7=-5

f(x) = 2x(2) - 7=-3

f(x) = 2x(3) - 7=-1

f(x) = 2x(4) - 7=1

Quadrilateral ABCD is similar to Quadrilateral EFGH. The scale factor is 3:2. If AB = 18, find EF.

Answers

Answer: EF = 12 units

Step-by-step explanation:

Given : Quadrilateral ABCD is similar to Quadrilateral EFGH.

The scale factor is 3:2.

We know that the scale factor is the ratio of the corresponding sides of two similar figures.

So if Quadrilateral ABCD is similar to Quadrilateral EFGH, the side AB corresponds to side EF.

If AB = 18, then we have the following equation:-

$(AB)/(EF)=(3)/(2)\n\n\Rightarrow(18)/(EF)=(3)/(2)\n\n\Rightarrow\ EF=(2*18)/(3)\n\n\Rightarrow\ EF=12$

EF =12

The equation of a line is y = 3x + 8 what is the gradient of the line

Answers

Answer: 3

Step-by-step explanation:

We can find the gradient, or slope, of the line by looking at the equation. This equation is given in slope-intercept form equation which is y = mx + b, where m is the gradient/slope.

y = 3x + 8

y = 3x + 8 ➜ the gradient is 3

The gradient of the line is 3.

How to find the gradient

The equation of line given is y = 3x + 8.

To find the gradient of the line, compare it with the standard slope-intercept form y = mx + b, where m is the gradient (slope).

Comparing the equations:

m (gradient) = 3

Hence, the gradient of the line is 3.
