(12.8+17.2)/((12-9)+(6-1))
30/(3+5)
30/8
15/4
3.75mph
It's been awhile since I've done this type of math but I hope I got it right.

How does finding the square root of a number compare to finding the cube root lf a number? Use the number 64 in your explainatio
xenn [34]

If you want to know the concept of square roots and cube roots ?

the square root of a number is that number which when multiplied by itself two times gives us that number

e.g.

√64 = x , so that (x)(x) = 64

and from our multiplication table we know that

(8)(8) = 64 , so that

√64 = 8

the cube root of a number is that number which when multiplied by itself three times gives us that number

e.g.

∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64

so ∛64 = 4

Could someone please help me figure out how to set up the equation for this problem? Thanks!
faust18 [17]

Answer:

12

Step-by-step explanation:


The sum of the measures of the interior angles is given by:


(n-2)*180\\


n:sides of the polygon


And in a convex polygon the sum of the exterior angles sums 360°


Then


(n-2)*180=5*(360)


You just solve it and the answer is 12.

Answer:

  • SU = 2
  • PX = 6 2/3

Step-by-step explanation:

The product of distances to the circle along a secant is the same for all secants intersecting a given point.

a. Secants SW and QT intersect at U. Thus ...

  (UT)(UQ) = (US)(UW)

  (1.5)(4) = (SU)(3)

  SU = (4)(1.5)/3

  SU = 2

__

b. Secants PT and PX intersect at P. Thus ...

  (PQ)(PT) = (PR)(PX)

  PX = (PQ)(PT)/PR) = (2.5)(2.5 +4 +1.5)/3 = 20/3

  PX = 6 2/3
