A piece of wire is bent into the shape of an isosceles triangle. The base angles are each 48 degree and the perpendicular height to the base is 6 cm. Calculate the length of the wire.

The density of a substance A rectangular s given as 13.6 g/cm^3 and that of a substance B as 11.3 g/cm^3. Determine the volume of B that would have the same mass as 50 cm^3 of A.

A rectangular floor of a room measures 5.4 m long and 4.2 m wide. The room is to be covered with square tiles. Calculate the minimum number of square tiles that can be used to cover the floor.

RORRO, what is the last expression a)Express b in term of, if necessary, R , L , C ?

Have problem with part c) too, please help?

THanks DOnny, yes me too. Anyone for Problem 3)b)? and Problem 1)f) B_0 for both cases. Formula or values would helpful, thanks.

B_0 for Q1?

A) M= AB = (-8+ 12)/2, (5 - (-5))/2 = (2, 0) N = OA (0 + -8)/2, (0 + 5)/2 = (-4, 2.5) |NM| = 36 + 6.25 = 42.25 NM = 6.5 B) NM = OB = (12 + 0)/2, (-5 + 0)/2 = (6, -2.5) |NM| = 10(10) + (-5)(-5) = 100 + 25 = 125 = 11.18 = 11.18/6.5 = 1.82 C)

I am still not get a solution C

(1, 0) - (6, -2.5) = (-5, . 2.5)
