Basketballs sell for 27.99 each at the super d and for 21.59 each at the bargain spot. if the coach buys a dozen basketballs, how much can he save by buying them at the bargain spot

he saves $76.8 by buying them at the bargain spot

Step-by-step explanation:

The cost of each basketball at the super D is 27.99

The cost of each basketball at the bargain spot is 21.59

If the coach buys a dozen basketballs, that is 12 basketballs,

The total cost of a dozen basketball at the super D is 27.99 × 12 = $335.88

The total cost of a dozen basketball at the bargain spot is 21.59 × 12 = $259.08

The amount saved by the coach by buying the basketballs at the bargain spot would be

335.88 - 259.08 = $76.8

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
