Answer:
The required equation is : 5 · 4000 = 20,000
Step-by-step explanation:
We have to use multiple of 10 for at least one factor.
So, in order to form our equation, we take one factor as 4000 which is a multiple of 10 (10 × 400 = 4000)
And the other condition to form the equation is given that the product should contain 4 zeros, so we need to multiply the first factor 4000 by some number such that the product contains 4 zeros.
Therefore, if we multiply 4000 by 5 we get the product as 20000 which contains 4 zeros.
Hence, 5 × 4000 = 20,000 is our required equation.
For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.
IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:

We apply distributive property:

So, on Saturday she spent 5 hours.

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
