∠P=∠R, ∠Q=2∠R
the three angles make a total of 180, so
∠P+∠R+∠Q=180
∠R+∠R+2∠R=180
∠R=45
∠P=45, ∠Q=90
Oscar's age = 16
Sister's age = 12
Current year: 16 / 12
Simplest form: 4 / 3 ; both are divisible by 4.
2 years after: (16 + 2) / (12 + 2) = 18 / 14 ; add two years to both numbers.
Simplest form: of 18 / 14 is 9 / 7; both are divisible by 2.
Answer:x<1/7 (5 - sqrt(130))
Step-by-step explanation:
Answer:
5.61×10^8 ton/day
Step-by-step explanation:
(2.08×10^5 ft³/s)·(8.64×10^4 s/day)·(6.24×10^1 lb/ft³)/(2×10^3 lb/ton)
= (2.08·8.64·6.24/2)×10^(5+4+1-3) ton/day
≈ 56.07×10^7 ton/day
≈ 5.61×10^8 ton/day
_____
We have expressed the answer using 3 significant digits, to match the precision of the rate and weight.
