Not enough info or diagram given.....

Suppose the square is 5 x 5     perimeter = 20   area = 25

Rectangle could be  9 x 1         Perimeter = 20   area = 9

Rectangle could be 8x 2           perimeter = 20   area = 16

rectangle could be 4 x 6           perimeter = 20   area = 24

etc.....

Need diagram or more info.....See what I mean?

Volume of a cone =   pi  r^2  h/3           r = x/2     h = x

Substitute     pi    (x/2)^2  x/3

                    V = pi x^3 /12           Solve for x

                    12V/pi  =  x^3

                     x = cubrt( 12V/pi)

5040 minutes  =   5040/60 = 84 hours =  84/24= 3 days 12 hours     = Tuesday at 5 AM

   Uh-Huh !

I will assume they did NOT double on Sunday....but rather it took until Monday for them to double to 4

Tuesday would be 8

Wednesday would be 16

Thurs   would be 32

Friday    64

  Saturday 128

See previous answer:

6:5      11 parts    66/11 = 6 flowers for each part      6 parts roses =   6(6) = 36 roses

x = first integer

x+1 = second    x+2 = next etc

x  +  x+1  +  x+2  +  x+3  +  x+4  +  x+5   +  x+6 = 63     gather all of the 'like' terms

7x  + 21=63     subtract 21 from both sides of the equation

7x = 42          divide thru by 7

x = 6 = smallest

x+6 = larges= 6+ 6= 12         6+ 12 = 18

Hmmmmm...... I think it might be THIS one:    (as I feel the refelection of the parent function (sin x) is accomplished by the initial ' - ' sign)

Your answer can have no more than the factor with the lowest sig figures : 2

c = d/p

c = 187 km / 28 l  = 6.7 km/l  ( rounded to 2 sig figures)
