Answer:
754.2
Step-by-step explanation:
First of all, we cannot solve the question the way it is. We need to make 0.1 into a whole number. If we move the decimal to the right, once, then it will become the number one.
Of course, what we do to one, we have to do to the other. We move the decimal to 75.42 to the right one. Now it is 754.2
That looks like the answer. The reason is because we are now dividing by one. Something divided by one, will always be itself.
Now we have the answer of 754.2.
πr² = π.5.5 = π25 units² or 78.5 units²
hope it helps...!!!
Answer: Hello mate!
our equation is 18√5−12√5 and we want to simplify it.
Simplification is triyng to "eliminate" all the roots (if possible). In our equation we have a square root of 5, wich is a problem, but let's se wat we can do:
18√5−12√5
= (18 - 12)√5
= 6√5
and we can not simplify furthermore, because the √5 cant be simplifyed.
Answer:
option D
4998 J
Step-by-step explanation:
Given in the question that,
mass of the diver = 68 kg
distance of the diver from the surface of a pool = 7.5 m
The gravitational potential energy of an object is given by
GPE = m(g)(h)
here,
<em> m is the mass of the diver</em>
<em> g is the acceleration due to gravity = 9.81m/s²</em>
<em> h is the height from the surface</em>
<em />
Plug values in the formula to calculate GPE
GPE = 68(9.8)(7.5)
= 4998 J
Therefore, the gravitational potential energy of the diver with respect to the surface of the pool is 4998 J
