Answer:
345 times 0.03 = 10.35 but we cant have 0.35 of a person so it is 10 people
Step-by-step explanation:
The pressure at a certain height is the pressure at sea level plus the hydrostatic pressure.
P = 80 psi + ΔP
where
ΔP = ρgh
ρ is the density of water equal to 62.4 lbm/ft³
ΔP = (62.4 lbm/ft³)(1 lbf/lbm)(4*10 + 2 ft)(1 ft/12 in)² = 18.2 psi
Thus,
P = 80 + 18.2
<em>P = 98.2 psi</em>
When you set up equations like this, look at the units for help. They cancel out during division and multiplication like numbers to give desired quantities. Rates can be reversed if need be (3 meters/sec or 1/3 sec/meter).
time × (distance / time) = distance
See.. time/time = 1; leaving distance
Subtract the rate of the opposing walkway...
t × (3 m/s - 1 m/s) = d
2t = d
Answer is then A.
Answer:
A) The correct inequality is: -18 < 53
B) The correct description is: Eduardo sent fewer text messages during May than April
Step-by-step explanation:
Month Number of message
April 53
May -18
A) The correct inequality is: -18 < 53
Reason:
We need to choose the correct inequality, negative number is less than positive number so the inequality will be -18 < 53
B) The correct description is: Eduardo sent fewer text messages during May than April
Reason:
Negative values shows that he has messaged under the allotted limit, while positive values shows the number of messages he was over the limit.
