y² =121 –36
y²=85
A) work out the radius of the mercury, giving your answer as an ordinary number
1 answer:
Answer:
a. 2,440 km
b.
Step-by-step explanation:
a. Diameter of Mercury =
Radius of Mercury = ½ of its diameter =
Radius of Mercury =
To convert the radius to ordinary number, multiply 2.44 by 1,000.
Radius of Mercury as an ordinary number =
b. Mass of Jupiter =
Mass of Saturn =
Difference between mass of Jupiter and mass of Saturn = (subtract 5.68 from 1.898 = 5.68. we would retain the largest exponent, which is raised to the lower of 27.)

Step-by-step explanation:
The overbar on decimal digits means they repeat forever.
Any fraction with a denominator consisting of powers of 2 and/or 5 will terminate. These can be converted to decimal by multiplying the fraction by a number to make the denominator an appropriate power of ten.
1 2/3 = 1.66666666666... repeating
1 3/5 = 1 (3·2)/(5·2) = 1 6/10 = 1.6
1 1/4 = 1 (1·25)/(4·25) = 1 25/100 = 1.25
1 33/50 = 1 (33·2)/(50·2) = 1 66/100 = 1.66
Of course, your calculator can tell you the decimal equivalents, too.
