Using proportions, it is found that the same job will take Mrs. Squirrel 6 hours.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The times are given as follows:

  • Mrs. Squirrel: x.
  • Mr. Turtle: 3 days.
  • Mr. Pigeon: 30 minutes = Half an hour = 1/48 day.

The ratios are as follows:

Turtle/Squirrel = Squirrel/Pigeon.

Hence:

\frac{3}{x} = \frac{x}{\frac{1}{48}}

x^2 = \frac{3}{48}

x^2 = \frac{1}{16}

x = \sqrt{\frac{1}{16}}

x = 1/4.

It takes 1/4 of a day for Mrs. Squirrel to do the job, hence 1/4 x 24 hours = 6 hours.

an open box is to be made from a piece of metal 16 by 30 inches by cutting out squares of equal size from the corners and bendin
blagie [28]
Let the lengths of the bottom of the box be x and y, and let the length of the squares being cu be z, then
V = xyz . . . (1)
2z + x = 16 => x = 16 - 2z . . . (2)
2z + y = 30 => y = 30 - 2z . . . (3)

Putting (2) and (3) into (1) gives:
V = (16 - 2z)(30 - 2z)z = z(480 - 32z - 60z + 4z^2) = z(480 - 92z + 4z^2) = 480z - 92z^2 + 4z^3
For maximum volume, dV/dz = 0
dV/dz = 480 - 184z + 12z^2 = 0
3z^2 - 46z + 120 = 0
z = 3 1/3 inches

Therefore, for maximum volume, a square of length 3 1/3 (3.33) inches should be cut out from each corner of the cardboard.
The maximum volume is 725 25/27 (725.9) cubic inches.

5x+7x-1/2x+1/4=6 helpppppp
oksian1 [2.3K]

Answer:

x = 1/2 = 0.500

Step-by-step explanation:

   Solve  :    2x-1 = 0

Add  1  to both sides of the equation :

                     2x = 1

Divide both sides of the equation by 2:

                    x = 1/2 = 0.500
