Verified answer
[4.871*10^21]/[1.9998*10^27]
=2.4357436/10^6
Mass of venus=2.4357436*10^(-6) times of mass of sun
Simple.
Let's say mass of Venus (V) = 4.871 x 10^21
Similarly mass of Sun (S) = 1.9998 x 10^27
Now you'll have to find out how many times of V is equal to S.
which is xV = S ==> x = S/V
which turns out to be x = 4.102 x 10^5
so, 4.102 x 10^5 x V = S
HTH.
(Mass of sun) / (Mass of Venus)
1.9998 x 10^27 / 4.871 x 10^21
edit: calculator answer is 4.1056 x 10^5
one million. because of the fact the ratio are 5 : 12 : thirteen and you recognize the fringe is ninety cm. The equation would be: 5x + 12x + 13x = ninety 30x = ninety x = 3. So the dimensions of the two facets could be multiply by utilising 3, hence 15 cm, 36 cm, and 39 cm. 2. occasion of consecutive integers:(one million, 2, 3, 4, 5, ...); (9, 10, eleven, 12, ...) because of the fact the fringe is 6, the equation would be: x + (x+one million) + (x+2) = 6 x + x + one million + x + 2 = 6 3x = 6 - 3 3x = 3 x = one million, then the dimensions of the two facets of the triangle are one million (x), 2 (x+one million) and 3 (x+2). 3. $2.60 in 40 5 money. Penny (one million cent) --------- Nickel (5 cents) --------- Dime (10 cents) x -----------------------------------2x---... - (x+2x) The equation would be: (one million cent * x) + (5 cents * 2x) + (10 cents * (40 5 - (x + 2x) = 260 x + 10x + (450 - 30x) = 260 -19x = -one hundred ninety x = 10 Then the form of penny are 10 money, nickels are 20 money, and dimes are 15 money. nevertheless engaged on the final question.
x=(1.9998x 10^27)/(4.871 x10^21)
x=4.105 x 10^5
WOW!!! It's really difficult!
