Answer:

21 yards

Step-by-step explanation:

The area of a quadrilateral with diagonals that are right angles to each other is given by ...

A = (d1)(d2)/2 . . . . where d1 and d2 are the lengths of the diagonals

493.5 yd² = (47 yd)(BD)/2 . . . . . . . . . . fill in the given information

Dividing by the coefficient of BD, we have ...

(2)(493.5 yd²)/(47 yd) = BD = 21 yd

A car dealership sells used cars for $7,000 and new cars for $16,000. If a total of 17 cars were sold for $191,000, how many of

Ipatiy [6.2K]

Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).
