Given that 24 hours is one full day, we can deduce that 2400 hours is 100 days. One full cycle from that time is equivalent to that time therefore, 2400 hours after 5pm is 5pm.

Answer:

5 pm because 2400 hours is just 100 days after 5pm which would still make it 5pm

Serga [27]

Answer:

p = 25,20 cm

h = 34,32 cm

A(min) = 864,86 cm²

Step-by-step explanation:

Let call p and h dimensions of a poster, ( length , and height respectively) and x and y  dimensions of the printed area of the poster then

p = x + 8        and      h = y + 12

Printed area = A(p) = 384 cm²     and   A(p) = x*y     ⇒ y = A(p)/x

y = 384 / x

Poster area  =  A(t) = ( x + 8 ) * ( y + 12 ) ⇒ A(t) =  ( x + 8 ) * [( 384/x ) + 12 ]

A(t)  =  384 + 12x + 3072/x + 96      A(t) = 480 + 3072/x + 12x

A(t)  =  [480x + 12x² + 3072 ] / x

A´(t) =  [(480 + 24x )* x  - (480x + 12x² + 3072]/x²

A´(t) =  0         [(480 + 24x )* x  - 480x - 12x² - 3072] =0

480x + 24x² -480x -12x² - 3072 = 0

12x² = 3072         x² = 296

x = 17,20 cm       and      y =  384/17,20      y = 22,32 cm

Notice  if you substitu the value of x = 17,20 in A(t) ; A(t) >0 so we have a minimun at that point

Then dimensions of the poster

p = 17,20 + 8  = 25,20 cm

h = 22.32 + 12 =34,32 cm

A(min) = 25,20 *34.32  

A(min) = 864,86 cm²

There are 8 girls for every 7 boys on a field trip.if there 56 girls on the trip how many students are on the trip
Ket [755]

Well the first thing you need to do is set up a proportion.

8 girls         56 girls                          

--------    =   -----------

7 boys             x


Now what we have to do is find out what we multiplied by 8 to get 56.

Simply divide.

56 ÷ 8 = 7

So, we figured out that the magic number is 7!

So we multiply the boy number by 7

7 x 7 = 49

So this means that there are 49 boys on the field trip.
