Terry usually rides his bike at 15 mph. If his riding speed is reduced by 3 mph, how far can he ride in 1.7 hours?

20.4 miles

Explanation:

Terry's normal speed while riding his bike =

Speed is reduced by .

So his speed now is

The time for which the distance needs to be found is

Distance is given by

So, the distance traveled in 1.7 hours is 20.4 miles.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
