Answer:

\frac{2}{3}in

Step-by-step explanation:

4in is the total so if it takes 6 hours. divide 4 by 6 and you get \frac{2}{3}.

Fast way to do this is to write out 4/6 and see they both can divide by 2. then you have the fraction in simplest form.

Given the roll of paper towels below how much plastic would be needed to cover the role so it can be sold given the diameter of
gladu [14]

Answer:

Amount of plastic need to cover paper role = 565.2 inches

Step-by-step explanation:

Given:

Diameter of paper role = 10 inch

Height of paper role = 13 inch

Find:

Amount of plastic need to cover paper role

Computation:

Radius of paper role = Diameter of paper role / 2

Radius of paper role = 10 / 2

Radius of paper role = 5 inch

Amount of plastic need to cover paper role = Total surface area of cylinder

Amount of plastic need to cover paper role = 2πr(h+r)

Amount of plastic need to cover paper role = 2(3.14)(5)(13+5)

Amount of plastic need to cover paper role = (3.14)(10)(18)

Amount of plastic need to cover paper role = 565.2 inches

Can somebody work out y/7=22
Alika [10]
Sure. So we can first identify our problem- there's a denominator. There's a simple fix, multiply both sides by the denominator to clear it. That leaves us with 7 = 22*7. y = 154.

Find \cos(\alpha)cos(α)cosine, left parenthesis, alpha, right parenthesis in the triangle. Choose 1 answer: Choose 1 answer: (Ch
icang [17]

Answer:

Check Explanation

Step-by-step explanation:

The diagram for this question is missing, but from the setup of the question, it is evident that the triangle to obtain cos α from is a right angled triangle.

It is evident from the options provided that the right angled triangle is one with dimensions of 20, 21 and 29.

These three dimensions perfectly form a Pythagorean triple.

So, the value of cos α now depends on the setup of the triangle.

From trigonometric relations, if α is an angle in the right angled triangle, cos α is given mathematically as

Cos α = (Adj/Hyp)

For this Pythagorean triple,

Hyp = hypotenuse side = 29

Adj = Adjacent side = 20 or 21, depending on the triangle's setup.

If the adjacent is 20,

Cos α = (20/29), option A is correct.

If the adjacent is 21,

Cos α = (21/29), option C is correct.

Hope this Helps!!!

Divide the number of people by the number of walls

9/9=1\frac{people}{wall}

so

it take 41 minutes to one people to paint one wall

therefore
