The bottom of a box has a surface area of 31.4 cm2. The mass of the box is 47.1 kilograms. Acceleration due to gravity at sea level is 9.80 m/s2. What pressure is exerted by the box where it rests?14.7 N
1.5 N
0.153 N
6.53 N
Answers
First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).
Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)
Consequently, I used the equation of pressure (P = Force/Area).
P = 461.58 N / .00314 m^2
P = 1.47 or 1.5 N
Answer:
Pressure = 147,000 N.
Step-by-step explanation:
Given : The bottom of a box has a surface area of 31.4 cm². The mass of the box is 47.1 kilograms. Acceleration due to gravity at sea level is 9.80 m/s².
To find : What pressure is exerted by the box where it rests.
Solution : We have given that area of box = 31.4 cm²
First we convert it in meter².
1 meter = 100 cm
31.4 cm² = 0.00314 meter².
Mass of box = 47.1 kg
Acceleration due to gravity = 9.80 m/s².
According to Newton second law of motion , F = mass * Acceleration due to gravity.
F = 47.1 * 9.8
F = 461.58 Newton.
Pressure = .
Plugging the values of force and area.
Pressure = .Pressure
Pressure = 147,000 N.
Therefore, Pressure = 147,000 N.

Answers
-a- b = 6 after the "A" cancel each other add the -2b with -b = -3b, then add 2
-------------- and 6
-3b=8 then you have to divide 8 by -3 = -2.6 -2.6 its b... now you have to solve for b step 1. a -2b = 2 step 2. a -2(-2.6)=2 step 3 a -5.3 = 2 then subtract -5.3 with 2 so that going to be 2 + 5.3 =7.3 then divide by a
final answer (-2.5,-7.3)
sorry its kinda hard to explained here, i hope you get the point :)

Then
Age of Leah = x + 6
Age of John = 5 + (x + 6)
= x + 11
Total of their ages = 41
So
x + x + 6 + x + 11 = 41
3x + 17 = 41
3x = 41 - 17
3x = 24
x = 24/3
= 8 years
So Sue is 8 years old.

1/2 * x^2 - x + 5 = 0 /*2
x^2 - 2x + 10 = 0
(x - 1)^2 + 9 = 0
1. x = 1 - 3 * i
2. x = 1 + 3 * i
The correct result would be x = 1 - 3 * i and x = 1 + 3 * i.

Answer:
it would cost $34.50 to purchase 7.5 lbs of walnuts.
Answer:
$34.50
Step-by-step explanation:
First find out how much 1/4 of a lb will cost.
3.45/3= 1.15
This is the cost for only 1/4 a lbs of chopped walnuts. Take this number and multiply it by 4 to find how much it would cost for 1 whole pound of walnuts.
1.15x4= 4.60
It costs $4.60 for a whole pound of walnuts. If you are trying to find how much it costs for 7.5 lbs, then multiply 4.60 by 7.5.
4.60x7.5= 34.5
For 7.5 lbs of walnuts will cost $34.50
