Answer:

For the triangle, the area is 7.5 in.

For the trapezoid, the area should be 90 cm

Sylvie folds a large piece of paper in half. The fold divides the paper into two equal parts. She folds it in half again. When s
Nikolay [14]
Each time you fold a paper it will double the amount of parts. When you think about it, it's just multiplying by 2 a bunch of times.

One fold is 2 times 1, which is 2.
The second fold is 2 times 2, which is 4.
The third fold is 4 times 2, which is 8.

Using this process, we can simplify that into exponents. If the amount of times you fold is x and the parts double for each fold, then the amount of parts can be represented by:

2^{x}

So if the amount of parts is given and we need the amount of folds, just keep doubling until you get to 64. The amount of times you doubled is the number of times Sylvie folded.

Later you will learn that the opposite of an exponent is a logarithm, which would look like this:

log_{2}(64) = ?

But don't worry about that yet.

The formula for the volume of a sphere is v= 4/3 m^3 what is the formula solved for r ?
Softa [21]

Answer:

            3V

r = ∛ ( ---------- )

            4π

Step-by-step explanation:

Please, enclose the fraction 4/3 inside parentheses, to eliminate any possibility of misreading this fraction.  Also note that this formula MUST include "pi," symbolized by π.

V = (4/3) π r³  This formula does NOT include "m," which is a unit of measurement, not a variable.

Our task is to solve this formula for the radius, r.

Divide both sides by (4/3) π, to isolate r³.  This results in:

      v               (4/3) π r³

-------------   =  -----------------

  (4/3) π             (4/3) π

                     

                       V              3V

Then r³ = --------------  =  --------

                   (4/3) π           4π

and r is found by taking the cube root of the above result:

            3V

r = ∛ ( ---------- )

            4π
