Answer:
Step-by-step explanation:
Is this the entire question? Some of it makes no sense without a diagram or something.
To get rid of A you actually have to solve the equation.
7h – 5(3h – 8) = –72 Remove the brackets
7h - 15h + 40 = - 72 Combine the like terms
- 8h + 40 = - 72 Subtract 40 from both sides
- 8h = -112 Divide by -8
h = 14
Well the depth is a whole number so A is true.
We don't know anything about time. But the answer is positive.
C is false because B is true.
We don't know exactly what the depth of the well is.
I would pick A, but you need the entire question.
Answer:
length measure of Pillow = 1.4 m
Step-by-step explanation:
Volume of Wedge = (area of base triangle) * length
Volume of Wedge = (1/2) * base * height * Length
base = 1 m
height = 0.5 m
Length = L m
Volume = 0.35 m³
=> (1/2) * 1 * 0.5 * L = 0.35
=> (0.5/2)L = 0.35
=> (0.5/2)L * 2 = 0.35 * 2
=> 0.5L * 2 = 0.7
=> 0.5L / 0.5 = 0.7 / 0.5
=> L = 1.4
