(a) Two quantities, y and x?, are in inverse proportion. If the difference in the values of y when x = 5 and when x = 10 is 1.2, find
(i)
an equation connecting x and y,
(ii) the value of y when x = -2.
(b), Two quantities, pand /7, are in direct proportion. When g is increased by
h%, the percentage increase in p is 200%. Find the value of h.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
