The answer should be $31.80.
Hope this helped!!!:)

According to given figure, The Triangle BDC is a right angled Triangle (Angle D = 90°)
So, we can apply Pythagoras theorem to find the Side a (Hypotenuse)
Now, let's solve ~
Therefore, Length of side a is 5 units ~
Answer:
Step-by-step explanation:
Triangle DEF is a right angle triangle.
From the given right angle triangle,
DE represents the hypotenuse of the right angle triangle.
With ∠E as the reference angle,
EF represents the adjacent side of the right angle triangle.
DF represents the opposite side of the right angle triangle.
To determine EF, we would apply
trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 49 = EF/8
EF = 8Cos49 = 8 × 0.6561
EF = 5.2488
Rounding to the nearest tenth, it becomes 5.2
Answer:
Option B.
Step-by-step explanation:
We need to express 505 kL in L.
Here, kL means kiloliter and L means liter.
We know that
1 kL = 1000 L
Using this conversion we can easily convert 505 kL in L.
Multiply both sides by 505.
505 × 1 kL = 505 × 1000 L
505 kL = 505,000 L
The value of 505 kL can be expressed as 505,000 L.
Therefore, the correct option is B.
The answer to this is x < -10/7
