1 A brand of cereal is usually sold in 750 g packs. During a special promotion an extra 15% is added to each box. What will the new weight be?

 862.50 g

Step-by-step explanation:

Find what 15% of 750  is  then add the obtained value to 750 to find the new weight.

15% * 750  = 112.5  

750 + 112.5 = 862.50

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.
