A gannet flies 24 1/2ft above sea level. It increases its elevation by 5ft. Then it dives and changes its elevation by -47 2/3ft. After it dives, what is the gannets elevation relative to sea level?

Its elevation relative to the sea level is -18 1/6 ft (it is 18 1/6 below sea level)

Step-by-step explanation:

Here, we want to calculate the elevation relative to sea level

The sea level refer to the base of the sea

We follow the flight procedure;

distance of 24 1/2 ft above sea level , then go further up by 5

its elevation now is 24 1/2 + 5 = 29 1/2 ft

A change of -47 2/3 ft

So the elevation now will be;

29 1/2 - 47 2/3

= 59/2 - 143/3

= (177-286)/6 = -109/6

= -18 1/6 ft

step-by-step explanation:

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
