Answer:
Step-by-step explanation:
FYI 7 over 2 (negative) is -3.5 on that number line, and since you want go to a number greater than -3/2, which is -1.5, now that we know our decimals, 1., it makes this easier and 2, now we make our inequality and solve it. Here we just do -3.5<x, and if you need to do it on the number line start from -7/2 and then go to -3/2 and draw an arrow, and the circle has to be an O not a black dot because it isnt greater/less than OR equal to.
-3.
It's the same as normal division unless they have different signs, then it's negative.
We break down the area into two triangles - since we're given all their side lengths, we use Heron's formula: ![[area]=\sqrt{s(s-a)(s-b)(s-c)},](https://tex.z-dn.net/?f=%5Barea%5D%3D%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D%2C)
where 
![[ABD]=\sqrt{(265)(115)(85)(65)}\approx 12975.92](https://tex.z-dn.net/?f=%5BABD%5D%3D%5Csqrt%7B%28265%29%28115%29%2885%29%2865%29%7D%5Capprox%2012975.92)
![[CBD]=\sqrt{(225)(125)(75)(25)}\approx 7261.84](https://tex.z-dn.net/?f=%5BCBD%5D%3D%5Csqrt%7B%28225%29%28125%29%2875%29%2825%29%7D%5Capprox%207261.84)
![[ABCD]=[ABD]+[CBD]\approx\boxed{20238\,\text{m}^2}.](https://tex.z-dn.net/?f=%5BABCD%5D%3D%5BABD%5D%2B%5BCBD%5D%5Capprox%5Cboxed%7B20238%5C%2C%5Ctext%7Bm%7D%5E2%7D.)
Answer:
19 feets
Step-by-step explanation:
Given the following:
Initial dive depth = 22 feet
Additional dive = 7 feets
Swims back up for 14 feets and dives down another 4 feets before finally finding the fish.
Hence, depth at which the fish was found :
22 feets + 7 feets - 14 feets + 4 feets
29 feets - 14 feets + 4 feets
15 feets + 4 feets
= 19 feets
Hence, the depth at which the fish was found is 19 feets.
