barxatty [35]

Answer:

$1\frac{1}{4}\ liters$

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

$1\frac{3}{5}=\frac{1*5+3}{5}=\frac{8}{5}$

step 2

Using proportion

$\frac{2}{(8/5)}\frac{liters}{doors} =\frac{x}{1}\frac{liters}{door}\\ \\x=2/(8/5)\\ \\x=10/8\ liters$

step 3

Convert to mixed number

$\frac{10}{8}\ liters=\frac{8}{8}+\frac{2}{8}=1\frac{1}{4}\ liters$

Ghella [55]

Answer:

0.204 KN

Step-by-step explanation:

Height above cube h= (100-15)/100 = 0.85 m

a) force on the top of the cube = ρgh×area

= 1000×9.81×0.85 = 8330 N/m^2

= 833 KN/m^2*0.15^2= 0.187 KN

b) Force on one side of the cube

on top = 8.33 KN/m^2

at bottom ρgh

= 1000×9.8×100/100

=9800 N/m^2

Net Force = area of the diagram

= 8.33×(15/100)^2 + 1/2(9.8-8.33)×(15/100)^2

= 0.204 KN

4vir4ik [10]

Answer:

286.94 cm

Step-by-step explanation:

Data:

Area = 8,607

b1 = 105

b2 = 123

Area = 1/2 * (b1 + b2) * h

h = 2 * Area/b1 + b2

h = 2 * 8,607/105 + 123

h = 286.94 cm

I'm not sure if it's right but that's what my calculator gave me.
