Me because i don't understand how to do it.: )

16.54

Step-by-step explanation:

patharam theorem A^2+B^2=C^2

(4.2)^2+(16)^2=273.64=(16.54)^2

D 17 cm

Step-by-step explanation:

The Pythagorean theorem states

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

4.2^2 + 16^2 = support ^2

17.64 +256 = support ^2

273.64 = support ^2

Take the square root of each side

sqrt(273.64) = sqrt(support ^2)

16.54206759 = support

The support is closest to 17 cm

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
