Expression: 5 - 1.5b = flour left (b=batches)
Answer: 0.5 cups of flour left
Im not certain on the expression but the answer is correct. Hope this helps!
Answer:
x = -2 , x = -6
Step-by-step explanation:
x^2 + 8x + 12 = 0
Factors
(x + 6)(x + 2) = 0
x + 6 = 0; x = -6
x + 2 = 0; x = -2
Cavalieri's Principle states that for two different solid shapes, if the altitude of the shapes is equal and the cross sections these shapes yield are the same from equal distances from their bases, then the shapes have equal volume.
Simply stated, if you cut two shapes of equal height from the same spot and they repeatedly yield the same cross section, then the shapes have equal volume. This is true in the case of a regular cylinder and an oblique cylinder. So the volume of the oblique cylinder may be calculated using πr²h, since its volume is equivalent to a normal cylinder of the same dimensions.
Volume = π x 10² x 20
Volume = 2000π cm³
14196/(39*28) = H
You use the volume of a rectangular prism, V = LWH
Fill in the values you already have:
14196 = 39*28*H, where height is depth.
To solve, you isolate the variable. Divide by (39*28) on both sides.
14196/(39*28) = H
