Elmer has a collection of 300 fossils .of these , 21% are fossilized snail shells. how many fossilized snail shells does Elmer have ?

Answer

63 are snail shells

Step-by-step explanation:

All I did was 300x.21 to get 63

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.

hope this is what you were asking for!
