Which of the following statements is not always true?
a. in a rhombus, the diagonals bisect opposite angles.
b. in a rhombus, the diagonals are perpendicular.
c. in a rhombus, the diagonals are congruent.
d. in a rhombus, all four sides are congruent.

Option C

Step-by-step explanation:

Option A: In a rhombus, the diagonals bisect opposite angles.

It is always true.

Option B : In a rhombus, the diagonals are perpendicular.

It is always True.

Option C : . In a rhombus, the diagonals are congruent.

It is not always true. If the diagonals become congruent then It becomes square.

Option D:  In a rhombus, all four sides are congruent.

It is always True.

Hence Option C is the statement which is not always true.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
