Work out the probability that the two biscuits were not the same type.

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
