this can be solve using the formulaP = rghwhere P is the total pressurer is the densityh is the heightg is the acceleration due to gravity
fist solve the total pressureP = 1.5 bar + 1 barP = 2.5 barP = 250,000 Pa
P = rgh250,000 = (997)(9.81)hh =25.56 m
PEMDAS
do parentheses first
4 x 10=40
40 x 10=400
30+6t - 3t-9
combine 6t and -3t and get 3t
30+3t=-9
subtract 30 on both sides
3t=-39
divide by 3
t=13
Answer:
y-8.3
Step-by-step explanation:
Y-7÷3±6=
BODMAS which means brackets ,of, division, multiplication ,addition, subtraction
we start by 7÷3=2.3.....
then 2.3..±6=8.3
then y-8.3 because one is a number and the other one is unknown we will leave it just like that
