If Sally has 400 apples and she gives 40 to each of her 10 friends how much does she have left?

The answer is 0.

10 friends each get 40, so

10 x 40 = 400

she has 400 at the beginning, after she gave her friends each 40 apples, she has zero apples.

the answer is ! ?

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.
