A. The circumference of a circle is the diameter times 3.14 aka pie and for instance, if you have two circles, circle A has a radius of 2 and diameter of 4 and circle B has a radius of 4 and diameter of 8, then if you compare the radius to the diameter (2/4 and 4/8) you get 1/2 for both and you know the circles are similar

Compute the permutation.
Anon25 [30]
So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula ^{a} P_{c} where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = ^{8} P_{3}
                                                                                       = 336

                                                <span> O R

</span>By using the formula Permutation =  \frac{a ! }{( a - c) !} where a is the number of available digits and c is the number of digits to be selected.<span>

</span>⇒  Permutation = \frac{8 ! }{( 8 - 3) !}
<span>
</span>⇒  Permutation = \frac{40, 320 }{120}
<span>
</span>⇒ Permutation = 336<span>

Each day, Lourdes reads 30 pages of a 450-page book. Write a linear equation to represent the number of pages Lourdes has left t
quester [9]

Answer:

The linear equation is y = 450 - 30 x, where y is the number of pages

Lourdes has left to read after x days

Step-by-step explanation:

- Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

  Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

  book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

  to read after x days

∴ y = 450 - 30 x

* The linear equation is y = 450 - 30 x, where y is the number of

  pages Lourdes has left to read after x days
