The width is OK......but.......the scale drawing will only cover  4 x 24  = 96 inches of the original painting's height of 120 in

So.....the width will fit on the paper but not the height

1) A right triangle is inscribed in a circle with a diameter 100 units long. What is the maximum area of the triangle, in square units?

Note that we can lay the hypotenuse of the right triangle along the diameter of the circle. And the height of this triangle will be the radius of the circle  with the two legs being equal.......so......the max area will be  =  (1/2)B*H  =  (1/2)D*R   =  (1/2)(100)(50)  = 2500 units^2

Let S be the union of the set of all points inside a regular nonagon with side length 2 units and the set of all points less than 1 unit away from a point on the perimeter of the nonagon. What, in units, is the perimeter of S?

The perimeter is comprised of 9 segments of length 2 plus the circumference of a circle with an radius of 1  [each curved part pf S is 1/9 of this circumference and there are 9 of them ]

The perimeter  = 9*2  + 2pi (1)   =  18 + 2pi ≈  24.28 units

First, we choose the suits. There are (4C3) ways to do this. Then, we choose one of 13 cards from each of the chosen suits. There are (13^3 = 2197)  ways to do this. The total number of ways to choose 3 cards of different suits is therefore (4*2197 = 8788)

I dont know what does it matter??

Perimeter of a square is 4*l = P

Here, P = 8a.

Area of a square is l^2.

680 divided by 136= 5

136*5=680

if that is what you meant :D

log, or logarithm, is an operation.  It is in the same category as a multiplication or addition.  Logistically, the question you asked doesn't really make sense as it would be in the same line as asking, "what is 7.2 divided by a multiplication sign?"

 What we're looking for here is the concentration of protons (H⁺) or more accurately hydronium ions (H₃O⁺).  A pH of 7.2 says that your solution is 10^(-7.2) molar H₃O⁺.  A pH of 13.1 would mean your solution is 10^(-13.1) molar H₃O⁺.  

Logarithms are operators saying "to what number must your base be raised to achieve a number?"  For instance, another way of writing 10^x = 1000 is writing log₁₀(1000) = x, where x = 3.  Exponentials and logarithms are like additiion/subtraction or multiplication/division.  They are inverse operators.

So, that means in order to know the concentration of H⁺ or H₃O⁺, we can multiply both sides by negative one and exponentiate 10^(-7.2) to learn the molarity.

If anything I said was unclear, please let me know.

Cheers.

Sqrt(625) =25

7.2  = - log (H).....multiply both sides by  -1

-7.2  = log (H)     and  we can write

10^-7.2  = H ≈   6.3 x 10^-8

Because the Dr. is HIS MOTHER!.

The doctor is his mother.

The parent function is  y = cos (x)     [the graph of the cosine ]

This is the graph of the cosine shifted to the right by pi units

V = (1/2)(4/3) * 3.14 * (13/2)^3  ≈ 575 in^3

Look at a graph, and see where it touches the Y axis, the vertical line.

Use the midpoint formula of X1 + X2/2, Y1 + Y2/2

If the triangle is SSS or SAS, then use law of cosines.

If the triangle is anything else, it is usually law of sines.
