Ihave two questions i need with. 1. if earth's mass is 20% higher, how long would it take earth's orbital period around the sun? (in days/years ) 3. if the earth was 20 million years farther from the sun, how will our year length change?

1).  The Earth would need much much much much much more mass than it has in order to see any change in our orbital period around the sun.  An increase of 20% won't jhave any effect.

3). This question isn't clear. "years" isn't a unit of length or distance. It can't describe a change in our distance from the sun, so we don't know what this question is actually asking.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
