fresh grapes lose 80% of their weight while drying. what weight of fresh grapes should you dry to get 140 grams of dried grapes

700 grammes

Step-by-step explanation:

If they lose 80% while dried, it means they have 20% of their weight after drying.

From the information in the question, we can see that the 20% here correlates with 140gramms. This means 1/5 of the weight is 140gramms.

Now let’s say total weight is x. It means 1/5 * x = 140. This means x/5 = 140.

Hence, x = 700 grammes

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.
