The pressure due to the depth in a liquid can be calculated as:
P = ρgh; ρ is the density in kg/m³, g is the acceleration due to gravity in m/s² and h is the depth in the fluid.
ρ = 0.65 g/cm³ = 650 kg/m³
P = 650 x 9.81 x 3
= 19100 Pascals
Pressure in atm = 19100/101325 atm
= 0.188 atm
Answer:
-1
Step-by-step explanation:
write it in the following manner:
-3x + 7 - 5x = 15
-8x + 7 = 15
-8x = 8
x = -1
Thus, the number has to be smaller than -1.
I think the number would be 1.
You could say she devided 3/4 by 1/8 and got what ever and that should be 6 i think i just did that in my head and why did this show up in the colledge section (sorry not good at grammar)
Answer about 49.
Step-by-step explanation:
Step 1. To model the situation in mathematical terms, express
63
%
as a fraction.
63
%
⇒
0.63
⇒

100
Step 2. To find
63
%
of the
78
teenagers, multiply
78
by
63
100
.
78
