25=100%
50%=12.5
10%=2.5
12.5(50%) +2.5(10%)= 50%(15)
so the answer is 60%
Answer:
x = -8 ± √62
Step-by-step explanation:
An equation needs an equals sign. I assume the expression equals zero?
x² + 16x + 2 = 0
To complete the square, start by making the leading coefficient 1 (which it already is).
Next, take half of the b coefficient, square it, and add the result to both sides.
(16/2)² = 8² = 64
x² + 16x + 64 + 2 = 64
Factor the perfect square:
(x + 8)² + 2 = 64
Solve for x:
(x + 8)² = 62
x + 8 = ±√62
x = -8 ± √62
The depth of the joist that was drilled by Freddy is 5 1/3 inches.
From the information given, we are informed that Freddy drilled into a piece of wood and a joist to attach them and that be drilled 4 inches and the wood was 1 1/3 inches thick.
Therefore, to get the depth that was drilled, we'll need to add the fractions given together. This will be:
= 4 + 1 1/3
= 5 1/3 inches.
Therefore, the depth of the joist that was drilled by Freddy is 5 1/3 inches.
