A submarine is 105 ft below the surface of the water, and it begins to ascend at a rate of 3 ft per min. After how many min will
the submarine be 82 ft below the surface??? Plzzz I will give you 100 points
1 answer:
Answer:
7 2/3 minutes
Step-by-step explanation:
We can write this equation in y = mx+b form
where m = 3 ft/min and b = -105 ft
x is the number of minutes and y is the depth
y = 3 * x -105
We want to find when y = -82
-82 = 3x -105
Add 105 to each side
-82+105 = 3x-105+105
23=3x
Divide by 3
23/3 = 3x/3
23/3=x
Changing into a mixed number
3 goes into 23 7 times with 2 left over
7 2/3 minutes

Answer:
True, these measures do form a right triangle.
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
(6)^2 + (8)^2 = (10)^2
36 + 64 = 100
100 = 100
So, its true these measurements do form a right triangle.
Oof I’m not quite sure how to do that
