Mark is creating a tarp to cover his new vegetable garden outside. He needs enough nylon to cover the garden which is 10 feet by

8 feet and then he will attach rope along the edges of the nylon to stake it down with. He goes to the store and the nylon costs $5.25 a square yard and the rope is $1.25 a foot. How much will it cost him to make the cover?

Answer:

$91.67.

Step-by-step explanation:  

We have been given that Mark is creating a tarp to cover his new vegetable garden outside. He needs enough nylon to cover the garden which is 10 feet by 8 feet and then he will attach rope along the edges of the nylon to stake it down with.

A. Let us find area covered by nylon by multiplying 10 by 8.

\text{ Amount of Nylon needed to cover the garden}=10\text{ feet}*8\text{ feet}

\text{ Amount of Nylon needed to cover the garden}=80\text{ feet}^{2}

Now let us convert area of needed nylon from square feet into square yard by multiplying 80 by 0.111111.

\text{ Amount of Nylon needed to cover the garden}=80*0.111111\text{ yards}^{2}

\text{ Amount of Nylon needed to cover the garden}=8.88889\text{ yards}^{2}

Now let us multiply 8.88889 by 5.25 to find the cost of nylon cover of the garden.

\text{ Cost of Nylon cover of the garden}=8.88889*5.25

\text{ Cost of Nylon cover of the garden}=46.6666725\approx 46.67

Therefore, the cost of nylon cover will be $46.67.

B. Now let us find length of rope by finding the perimeter of the garden.

\text{Length of rope}=2(10+8)\text{ feet}

\text{Length of rope}=2(18)\text{ feet}

\text{Length of rope}=36\text{ feet}

Now let us find the cost of 36 feet long rope by multiplying 36 by 1.25.

\text{Cost of rope}=36*1.25

\text{Cost of rope}=45

Therefore, the cost of rope will be $45.

To find the total cost to make the cover we will add cost of nylon cover and cost of rope.

\text{Total cost to make the cover}=45+46.67

\text{Total cost to make the cover}=91.67

Therefore, it will cost $91.67 for Mark to make the cover for vegetable garden.

Amelie is making a recipe that uses 1 3/4 cups flour. She is making 2 1/2 times the original recipe.
elixir [45]

Answer:

She would need 4\frac{3}{8} flour to make  2\frac{1}{2} times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = 1 \frac{3}{4}\ cups of flour.

So, to make 2\frac{1}{2} times the recipe she would need =1 \frac{3}{4}\times 2\frac{1}{2}.

We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).

=\frac{7}{4}\times \frac{5}{2}

=\frac{35}{8}

Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

\frac{35}{8}=4\frac{3}{8}

So, she would need 4\frac{3}{8} flour to make  2\frac{1}{2} times the recipe.

Solving these quadratics for x using complete the square 3x^2-4x-1=0. Show your work.
UkoKoshka [18]
Answer: x = (sqrt(7) + 2)/3 and
x = ( – sqrt(7) + 2)/3

Explanation:

3x^2 - 4x - 1 = 0

Divide both sides by 3:

3x^2/3 - 4/3x - 1/3 = 0/3
x^2 - 4/3x - 1/3 = 0
x^2 - 4/3x = 1/3
x^2 - 4/3x + (2/3)^2 = 1/3 + (2/3)^2
(x - 2/3)^2 = 1/3 + 4/9
(x - 2/3)^2 = 7/9

Sqrt both sides:

x - 2/3 = sqrt (7/9)
x - 2/3 = |sqrt(7)/3|

Set x -2/3 = sqrt(7)/3

=> x = (sqrt(7) + 2)/3

Set x - 2/3 = - sqrt(7)/3

=> x = ( - sqrt(7) + 2)/3
