45 fish
1 L = 1,000 mL
180(1,000) = 180,000
180 L = 180,000 mL
180,000/4,000 = 45
Answer:
8
Step-by-step explanation:
Using sine rule,
sin 80° ÷ 10 = sin 50° ÷ x
x = sin 50° ÷ (sin 80° ÷ 10)
= 7.77 --> 8
Answer:
Maurice is correct.
Step-by-step explanation:
Because in order to multiply correctly you must find the total number of turbines that has been built.
Apply substitution
x+4(-2x-4)=19
x – 8x – 16 = 19
-7x = 19 + 16
-7x = 35
x = -5
Then substitute this value to the other equation
y=-2x-4
y = -2(-5) – 4
y = 10 – 4
y = 6
the answer is then letter A. (-5,6)
