I would use a proportion
51.03/88% = x/100%
Which is saying: if 51.03 is 88% of the number, what is 100% of the number
Cross multiply to get x=57.99
Y+Y+30=90
2Y=60 /:2
Y=30
PNQ=30°
QNO=30+30=60°
Bus stop method. 3 goes into 4 once. Remainer 1. Add that to the 5. Makes 15. 3 into 15 goes 5 times. No remainder. 3 goes into 9, 3 times and no remainer. So 459/3 is 153
Answer:
3.11
Step-by-step explanation:
f(4)=f(4-1)+2
=f(3)+2
=f(3-1)+2+2
=f(2)+4
=f(2-1)+2+4
=f(1)+6
=5+6 (f(1)=5)
=11
It is 4170 I believe if my calculations are correct
