Answer:
3(4g + 6) = 2(6g + 9)
Distribute 3 and 2 inside their respective parentheses.
12g + 18 = 12g + 18
Step-by-step explanation:
(2g+3)(5g^2-6)
or (5g^2-6)(2g+3)
Answer:
Answer 2
Step-by-step explanation:
1 and 3 are not linear or not straight
4 there can't be more then one value for x
First, we want to convert 700 feet to inches:700 feet (12 inches/ft) = 8400 inchesWe know that the diameter is 16 inches, so the circumference is 16π inches or 50.3 inches.We can divide 8400/50.3 to get about 167.1 rotations.
The answer is C!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
a. The water in the second tank decreases at a faster rate than the water in the first tank. The initial water level in the first tank is greater than the initial water level in the second tank.
Step-by-step explanation:
Step 1:
It is given that the time remaining in first tank is given by the equation y = -10x + 80. We can get the total water in the tank by substituting x = 0 in the equation. The total volume of water in first tank is 80 litres.
Step 2:
The value of y in the equation y = -10x + 80 will be 0 when the tank is fully empty. When y = 0 , 10x = 80, so x = 8. We can conclude that the first tank empties fully in 8 minutes.
In 8 minutes 80 litres of water is emptied from first tank. So the water in the first tank decreases at rate of 80 / 8 = 10 litres per minute
Step 3:
As per the given table for the second tank, 60 litres of water remains when x =0. So the total volume of water in the second tank = 60 litres.
Step 4:
As per the given table for the second tank, the volume becomes 0 in 5 minutes. In 5 minutes 60 litres of water is emptied from second tank. So the water in second tank decreases at rate of 60 / 5 = 12 litres per minute.
Step 5:
The initial volume of water in first tank is higher. The water in second tank decreases at a faster rate than the first tank.
Step 6:
The only correct option is:
a. The water in second tank decreases at a faster rate than the water in the first tank. The initial water level in first tank is greater than the initial water level in the second tank.
