So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}
Answer:
2√137
Step-by-step explanation:
To find AB, we can use the Pythagorean Theorem (a² + b² = c²). In this case, a = 22, b = 8 and we're solving for c, therefore:
22² + 8² = c²
484 + 64 = c²
548 = c²
c = ± √548 = ± 2√137
c = -2√137 is an extraneous solution because the length of a side of a triangle cannot be negative, therefore, the answer is 2√137.
Could you take a picture that looks more clear so I can figure it out? Thank u!
For the first one is definitely 0.12
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.
0 = Surface level
Beneath means subtraction.
0 - 96 = -96
Climbs means addition.
-96 + 49 = -47
The scuba diver is -47 feet beneath the surface of the lake.
