(PLEAS HELPPP)Helen went with her mother to a fabric Sale. on the sale table, fabric was marked 25% off. The regular price of a certain bolt of fabric was $7.79 a yard B. Change the percent into fraction to estimate the discount and the sale price of 4 yards
discount __
Sale price_
C. Now find the exact sale price of 4 yards. find the cost of 4 yards at regular price first, then figure the discount on the total.

B) Discount: 0.25

    Sale Price: 31.16

C) Regular: 31.16

    With Discount: 23.37

Step-by-step explanation:

B) Discount: Just move the decimal 2 places to left or dividing the value by             100

Sale price: 7.79·4= 31.16

C) 31.16·.25= 7.79

31.16-7.79= 23.37

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.
