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.

Help pleaseeee I don’t understand
Amiraneli [1.4K]

You need to multiply three on both sides, add 6x to both sides, then divide by 4 on both sides. In the end, you will get y=3/2x+21/2.

which expression is equal to 33⋅35?3−23 to the power of negative 2323 squared 383 to the power of 8315
lawyer [7]

By applying Exponential laws, option no. c  which is, 3^8 stands correct.

What are exponents?

  • A number's exponent indicates how many times that number has been multiplied by itself.
  • However many times multiplying a given number is indicated by its exponent. Powers and indices are other names for exponents.
  • An indication of the action of elevating to a power that is printed above and on the side of a mathematical form
  • Exponent-related problems are solved using the rules of exponents or the properties of exponents. These characteristics are regarded as fundamental exponents rules that must be adhered to when solving exponents.

Given that,

(3^3)*(3^5)

Applying the law of exponents to the given expression,

a^m*a^n=a^{m+n}

Putting the given value in the above expression, we get,

(3^3)*(3^5) = 3^{3+5} =3^8

Hence, by applying Exponential laws, option no. c  which is, 3^8 stands correct.
