Answer:
4s+14t
Step-by-step explanation:
2*[(s+5t)+(s+2t)]
=2*(2s+7t)
=4s+14t
Here,
A sphere has 7cm radius
And it’s cut into tow half (2 hemispheres)
So, the radius of a hemisphere is also 7cm
Now,
TSA of hemisphere = 3 pie r^2
=3*22/7*7^2
=3*22/7*49
=3234/7
=462cm^2
Lastly,
The TSA of 2 hemispheres = 2* 462
=924cm^2
Hence,
The total surface area of the 2 hemisphere is 924cm^2
It’s F I think
I’m not sure
Say there are two fractions, 1/3 and 3/7. first, find a common denominator (21). Multiply each number like this: 1/3 * 7/7= 7/21 and 3/7 * 3/3=9/21. Now, just compare. 7/21 is less than 9/21. :)
Answer: The force is 6.25 times stronger.
Step-by-step explanation:
The formula to find the force of attraction between any two object is given by :-
(i)
, where M and m are the masses of the objects , d is the distance between them and G is gravitational constant.
If you decrease the distance between two celestial objects by a factor of 2.5, then , the new distance will become
Plug this in the above formula , we get
Hence, the force is 6.25 times stronger.
