I'm not 100% sure but this is how i worked it out
1/3 x 114/1 = 38
114 - 38 = 76 hydrogen
Hope this helps
Answer:
all of them are much larger except number 2 which is close to 1
Step-by-step explanation:
Answer to A and B.
The area of rectangle: 22.8×14.5=330.6 ft²The area of rectangle: 22.8×14.5=330.6 ft²
The area of triangle: 12⋅12⋅22.8=136.8 ft²The area of triangle: 12·12·22.8=136.8 ft²
The total area of figure: 330.6+136.8=467.4 ft²The total area of figure: 330.6+136.8=467.4 ft²
B: In order to find how many gallons of paint are needed, we need to divide the total area that needs to be painted (467.4 square ft) by the area one gallon covers (350 square ft)
467.4 ÷ 350 ≈ 1.34 gallons
Since only whole gallons of paint can be purchased, you will need 2 gallons of paint.
At $20 each, the cost will be 2 x $20 or $40.

Answer:
Well all you need is 2 points to calculate slope
You can follow the equation,
{y2-y1 / x2-x1} = slope
-2-1=-3
4-0=4
-3/4
-3/4 is the slope
