Which is one advantage of using a reflecting telescope instead of a refracting telescope? Reflecting telescopes are less expensive.
Reflecting telescopes produce clearer images.
Reflecting telescopes require only concave lenses.
Reflecting telescopes usually take up less space.

THE CORRECT ANSWER IS B "Reflecting telescopes produce clearer images."
I GOT IT RIGHT ON THE TEST

CONGRATSSS!

Explanation:

Here's why your answer is correct:

A reflecting telescope is one that makes use of mirrors. A mirror, unlike a lens, can be very thin. It is not necessary for a larger mirror to be thicker. By bouncing off the mirror, light is focused. So all the mirror needs is the correct curved shape. Making a large, near-perfect mirror is substantially easier than making a large, near-perfect lens. Mirrors are also easier to clean and polish than lenses because they are one-sided.

So option B is correct

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
