If you write down your information first it will be easier to visualise a method:

15 rolls of ribbon, each is 5\frac{3}{8} yards long. 10 wedding baskets. She takes \frac{3}{4} yards away from every basket.

So, in mathematical terms:

(15*5\frac{3}{8})-10(\frac{3}{4})\\\\(15*\frac{43}{8})-5(\frac{3}{2})\\\\(\frac{645}{8})-\frac{15}{2}\\\\\frac{645}{8}-\frac{60}{8}\\\\\frac{585}{8}\\\\585/8=73.125

Your answer is \frac{585}{8} or 73.125 yards.

I would either graph these (which would be a easiest) then you would see a line that goes through (0, -2) on the y-axis
And you can either determine the slope from the graph or pick two points above and find the slope.




or spread them out evenly and fill out the missing pieces.

-8. -4



-4. -3



0



4. -1

6. -0.5

8



12. 1


Fill in the middle values and you can put (6,-0.5) on there

What pattern do u see? This way would be pretty hard.

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
Cerrena [4.2K]

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.

How do you do factoring the gcf out of a binomial
iVinArrow [24]
In general: look for what the terms have in common. for example, take the binomial 2x² - 4x. you would be able to factor out a "2" because of the coefficients, and both terms have an "x" -- you can take that out too. that makes your GCF 2x. technically, what you're doing with factoring is dividing the terms by your GCF--2x² divided by 2x leaves you with x, and 4x divided by 2x leaves you with two. that's how you end up with (x - 2) in your binomial. your result looks like this: 2x(x - 2).

if you have any specific binomials you need help with, feel free to send me a message or comment on this and i'll see if i can help. if you're just asking in general, then just remember to look for what the terms have in common, then take it out.

Given the isosceles right triangle in which each of its legs has a measure of 4:

Let c = hypotenuse
a = one of the legs of the triangle
b = the other leg of the triangle

Use the Pythagorean Theorem to solve for the measure of the hypotenuse:

c^ 2 = a^2 + b^2

c^ 2 = (4)^2 + (4)^2
c^ 2 = 16 + 16
c^2 = 32

Next, take the square root of each side of the equation to solve for c:

√(c^2) = √(32)

c = 4√(2)

Therefore, the correct answer is Option 3) 4√(2).
