The fence is rectangular, so use the formula for the area of a rectangle: .

You know the area (A = 300 ft2) and the width (w = 4 ft), but not the length. The formula would be more useful if it were rewritten to solve for the length in terms of the area and width. Rewrite the formula by dividing both sides by the width.


Use the formula to find the length of fence (in feet) that can be painted.

Answers

Answer 1

Answer: New formula is A/w=l

Length equals 75ft.

Step-by-step explanation:

A=l x w           Area of a rectangle formula.

A/w=l              Solve for length

300=l x 4      

300=l x 4

4           4

300/4=l

75=l

Answer 2

The new formula is A/w=l and  Length= 75ft.

A=l x w        (Area of a rectangle formula)

A/w=l           (Solve for length)

300=l x 4      

300=l x 4

300/4=l

75=l

What's the vicinity system?

Given a rectangle with duration l and width w, the system for the location is A = lw (rectangle). that is, the place of the rectangle is the duration accelerated by the width. As a unique case, as l = w inside the case of a rectangular, the location of a rectangular with facet duration s is given with the aid of the formulation: A = s2 (rectangular)

The perimeter P of a rectangle is given through the formulation, P=2l+2w, wherein l is the period and w is the width of the rectangle. The location A of a rectangle is given with the aid of the system, A=lw, where l is the length and w is the width.

1. Contaminated water is subjected to a cleaning process. The concentration of the pollutants is initially 5 mg per liter of water. If the cleaning process can reduce the pollutant by 10% each hour, define a function that can represent the concentration of pollutants in the water in terms of the number of hours that the cleaning process has taken place.​

Answers

Answer:

[tex]C(t)=5\cdot(0.9)^t[/tex]

Step-by-step explanation:

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

[tex]C(t)=C_o\cdot(1-r)^t[/tex]

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The concentration of the pollutants starts at Co=5 mg/lt. We also know the pollutant reduces its concentration by 10% each hour. This gives us a value of r = 10% / 100 = 0.1

Substituting into the general equation:

[tex]C(t)=5\cdot(1-0.1)^t[/tex]

Operating:

[tex]\boxed{C(t)=5\cdot(0.9)^t}[/tex]

y(n) = 5(0.9)ⁿ

To answer this, we will make use of the exponential decaying function which is given by;

y(n) = a(1 - b)ⁿ

where;

y is the final amount at time n,

a is the original amount

b is the decay factor

x is the amount of time that has passed.

We are told that the initial concentration of the pollutants is 5 mg/L

Thus;

a = 5 mg/L.

We are told that the pollutant reduces its concentration by 10% each hour. Thus; b= 10%

b = 0.1

Therefore Plugging in the relevant values into y(n) = a(1 - b)ⁿ, we have;

y(n) = 5(1 - 0.1)ⁿ

y(n) = 5(0.9)ⁿ

Diameter endpoints (2, 5) and (0, 3)

C
Find an equation of the circle and sketch it if it has:
Center on x=3, tangent y-axis at (0, 5)

Answers

Answer:

A. [tex](x+5)^2+(y-4)^2=16[/tex]

B. [tex](x-1)^2+(y-4)^2=2\\[/tex]

C. [tex]$\left(x-3\right)^2+\left(y-5\right)^2=9$[/tex]

Step-by-Step Explanation:

A. Tangent to x-axis, r=4, contains (-5,8)

The equation of a circle is this: [tex](x-h)^2+(y-k)^2=r^2\\[/tex]

Therefore, we know that our equation will be: [tex](x-h)^2+(y-k)^2=4^2=16[/tex]

Because the circle is tangent to the x-axis, the point (-5,8) will be the top of the circle.

Therefore, the center is (-5,4), where -5=h and 4=k.

The answer is [tex](x+5)^2+(y-4)^2=16[/tex]

B. Diameter endpoints (2,5) and (0,3)

To solve for the diameter, we can use this equation: [tex]d=\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2 }[/tex]

[tex]d=\sqrt{(2-0)^2+(5-3)^2 }\\\\d=\sqrt{2^2+2^2}=\sqrt{4+4} =\sqrt{8}= 2\sqrt{2}[/tex]

Because the radius is half of the diameter, [tex]r=\sqrt{2}[/tex]

Therefore, we know that our equation will be: [tex](x-h)^2+(y-k)^2=(\sqrt{2}) ^2=2[/tex]

Then, we can decipher that h=1, as the midpoint of 0 and 2 is 1, and k=4, as the midpoint of 3 and 5 is 4.

The answer is [tex](x-1)^2+(y-4)^2=2[/tex]

C. Center on x=3, tangent to y-axis at (0,5)

We can see that the center is (3,5). Therefore, the equation is [tex](x-3)^2+(y-5)^2=r^2\\[/tex]

To solve for r, we can substitute the point (0,5) into the equation.

[tex](0-3)^2+(5-5)^2=r^2\\(-3)^2+(0)^2=r^2\\r^2=9[/tex]

The answer is [tex](x-3)^2+(y-5)^2=9[/tex]

4

Answers

Answer:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

Step-by-step explanation:

The line equation, y = -2x + 7 is written in the slope-intercept form, which is represented by the formula, y = mx + b.

m is the slope, while b is the y-intercept.

Therefore, the slope of the line of the linear equation, y = -2x + 7 is -2.

Find the slope of the line shown in the graph using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].

Use the coordinates of any two points on the line. Let's use (0, 5) and (5, 0)

Let,

[tex] (0, 5) = (x_1, y_1) [/tex]

[tex] (5, 0) = (x_2, y_2) [/tex]

[tex] m = \frac{0 - 5}{5 - 0} = \frac{-5}{5} = -1 [/tex]

Therefore:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

A box of Shredded Wheat weighs 0.35 kg and a box of Weetabix weighs 9/25 kg?

Which box is heavier?

Show your work

PLEASE HELP DUE TONIGHT THANK YOU SO MUCH

Answers

Answer:  The box of Weetabix is heavier by 0.01 kg

Step-by-step explanation:

Divide 9/25 to get the decimal equivalent

9÷25 =0.36

Compare Shredded Wheat at 0.35 kg to Weetabix at 0.36 kg

Weight of the box of Shredded Wheat is [tex]0.35[/tex] kg and weight of the box of Weetabix is [tex]0.45[/tex] kg.

So, the box of Weetabix is heavier.

Weight of the box of Shredded Wheat [tex]= 0.35[/tex] kg.

Weight of the box of Weetabix [tex]= \frac{9}{25}[/tex] kg.

Here to compare the two weights, first make both of them similar.

Either make both of them decimals or both of them fraction.

Here, we will make both the weights decimals.

[tex]\frac{9}{20} = 0.45[/tex]

Now, [tex]0.45>0.35[/tex]

So, the box of Weetabix is heavier.

You are filling piñatas for your sister's birthday party. The list shows the gifts you are putting into the piñatas. You want identical groups of gifts in each piñata with no gifts left over. What is the greatest number of piñatas you can make?

Answers

Answer:

The greatest number of piñatas you can make with the gifts is:

To identify the greatest number of piñatas, you must think in a number that can divide another and obtain a whole number with this:

182442

Bigger the number, greater the number of piñatas, in this case, you can see the numbers given can be divided into four numbers obtaining a whole number: 1, 2, 3, and 6. Remember that the best number is the greatest, in this case, number six. Now you proceed to divide the numbers into 6:
