The volume V of a cone varies jointly as the area of the base B and the height

Mathematics
1 answer:
seraphim [82]3 years ago
3 0

Answer:

h = 9 cm.

Step-by-step explanation:

V = kBh   where k is the constant of variation.

From the given info:

32 = k*16*6 = 96k

So k = 32/96 = 1/3.

So we have the equation of variation:

V = 1/3Bh

When V = 60 B = 20, so:

60 = 1/3 20h

20h = 60 * 3 = 180

h = 180 /20 = 9.

Solve 4|p - 3|= |2p + 8|.
nataly862011 [7]

Answer: p = 10

Step-by-step explanation:

4|p-3| = |2p + 8|. First multiply 4 with p and -3. You’ll get 4p-12. You will now have 4p-12 = 2p+8. You have to switch -12 & 2p, but you have to switch the signs so -12 turns into +12 and 2p turns into -2p. 4p-2p = 8+12. This makes  2p=20. Your final answer will be p = 10.

Very confused*** help
jeyben [28]

First way of finding area is the usual formula.

Area of a rectangle = Length × Breadth

= 3x × x

= 3x^2

Second way of finding area of the bigger rectangle is adding both the rectangles' areas and subtracting by the area of the smaller rectangle.

Area of smaller rectangle:

Length × Breadth = 2 × x

= 2x

Area of bigger rectangle + Area of smaller rectangle = 3x^2 + 2x

Subtracting it by the area of the smaller rectangle:

3x^2 + 2x - 2x = 3x^2
