A fish is swimming 10.2 feet below the surface of the water. It then descends another 12.85 feet. What subtraction expression can be used to find the new position of the fish? What is the position of the fish in relation to the surface of the water?

The new position of the fish is  = -23.05 feet

Step-by-step explanation:

We are being told that a fish is swimming 10.2 feet below the water surface

i.e. -10.2 feet

The fish then descend another 12.85 feet.

This means;

The first goes down from its first initial depth.

Mathematically, the subtraction expression that can be used to find the new position of the fish is:

= ( -10.2 + (-12.85) ) feet

Then, the new position of the fish is

= -23.05 feet

the first one : -10.2 - 12.85

second one : -23.05ft

Step-by-step explanation:

edg. said i got it right <3

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
