Answer:
Justin's displacement is 12.65 km.
Step-by-step explanation:
Since Justin rides 12 km south, then 4 km west, his displacement can be determined by applying Pythagoras theorem to the sketch of his journey. Let his displacement be represented by s,
=
+ 
=
+ 
= 16 + 144
= 160
⇒ s = 
= 12.6491
s ≅ 12.65 km
Justin's displacement is 12.65 km.

Answer:
Step-by-step explanation:
Given that:
Ava bring 34 food to the picnic
Kate bring 16 food to the picnic
JIn brings 112 food to the picnic
To enter these digits by applying equivalent fractions with a denominator of 12;
Their respective numerical expression is:
Ava = 
Ava brought
food to the picnic
Kate = 
Kate brought
food to the picnic
Jin = 
Jin brought
food to the picnic
Original price is the jeans = Rs450
Discount = 25%
Discount amount
= 25% of 450
= 25%(450)
= 25/100 × 450
= 25/10 × 45
= 5/2 × 45
= 225/2
= Rs112.5
Price after discount
= original price - discount amount
= 450 - 112.5
= Rs337.5
I'm not sure that I am 100% right but I'll give it a shot.
50+75= 125*0.35=43.75
