The mass of Mars is 6.42x10-23 kilograms. The mass of mercury is 3.3x10-23 kilograms. What is the combined mass in scientific no

Paraphin [41]

<em>combined mass in scientific notation can be written as</em> 97.2× $10^{-24}$ kg

Scientific notation can be regarded as a way of writing very large as well as very small numbers.

Mars of mass= (6.42x $10^{-23}$ kg )

Mercury= (3.3x $10^{-23}$ kilograms)

Then we add together

(6.42x $10^{-23}$ )+ (3.3x $10^{-23}$ ) kilograms.

= 9.45 × $10^{-24}$ kilograms

Therefore, combined mass in scientific notation can be written as 97.2× $10^{-24}$ kg

Solve the equation by finding square roots. To start, remember to isolate x^2. Equation= x^2+4=20

prohojiy [21]

Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4.
Plug it in to check.
(4)^2+4=20
16+4=20
20=20

Ultimately your final answer is X=4

15m + 2n, first you have to pair the matching variables, 8m and 7m along with the sign in front of them. so 8m(+7m), you would then add those then do the same with the other, +4n(postive) and -2n, so subtract 2 from 4 and get 2. put them together and it’s 15m+2
