Answer:
Step-by-step explanation:
The pressure exerted by an object is given by:
where
F is the magnitude of the force
A is the area of the surface perpendicular to the force
In this problem, the force is the weight of the books + the shelf, which is given by
where
m = 262 kg is the total mass
is the acceleration of gravity
Substituting,
The area of the four legs is:
Therefore, the pressure exerted on them is:
Answer:
Amount invested at 8% is $9000 and amount invested at 18% is $21000.
Step-by-step explanation:
Let amount invested at 8% be x.
Let amount invested at 18% be y.
We get the 1st equation as:
........(1)
We get the second equation as:
=>
or getting rid of the decimal by multiplying by 100 on both sides.
........(2)
Multiplying (1) by 8 and subtracting from (2) we get
So, y = 21000
And
So, x = 9000
Therefore, amount invested at 8% is $9000 and amount invested at 18% is $21000.
Answer:
B. Inscribed equilateral triangle.
Step-by-step explanation:
An equilateral triangle is a type of triangle that has all sides to have the same length.
An inscribed figure or shape is one which has been constructed within the boundaries of another figure or shape.
In the given question, the markings is construction of an inscribed equilateral triangle. This procedure of the construction after completion, generate the triangle as shown in the construction attached to this answer.
No, I simply apply t=2 to the equation 16t2, and get 64 which is less than 75ft, so it would take longer time to hit the ground. So the answer is no I think.
