4.5 ÷ 3 = 1.5
This means that the ratio has increased by 1.5
Since anything multiplied on one side of a ratio has to be multiplied on the other side too, we multiply 1.5 by 4:
1.5 X 4 = 6
The width would be 6cm
Answer:
B) 1, 2, 2, 1
Step-by-step explanation:
In given equation:
Left side: Right Side:
2 Na 1 Na
1 S 1 S
1 H 2 H
1 Cl 1 Cl
To equal the number of Na and H atoms on both sides, HCl and NaCl will have a coefficient of 2 to balance the equation while Na₂S and H₂S will have a coefficient of 1.
1 Na₂S + 2 HCl ⇒ 2 NaCl + 1 H₂S
Answer:
-1/2.
Step-by-step explanation:
Slope = rise / run
= (1 - -7) / (-1 -3)
= 8/-4
= -1/2.
Okay, so first divide 336 / 12 to find out how many miles are driven on each gallon. 336 / 12 = 28 So the car travels 28 miles per gallon (mpg).
Then, divide 1,344 / 28 1,344 / 28 = 48
And there's your answer! D) 48 gallons
