Just add all 3 numbers up together:
6.45+ 0.15+0.5
=7.1
Since it was three days multiply the 7.1 by three
=7.1x3
=24
So for three days derrick rode for 24 km
Hoped I helped :)
Answer:
a = 2.5
b = 4.33
Step-by-step explanation:
a = sin(30 degrees) = o/5 = 2.5
b = cos(30 degrees) = a/5 = (5root3) / 2 or about 4.33
verify using Pythagorean theorem
2.5^2 + 4.33^2 = 5^2
6.25 + 18.75 = 25
25 = 25
1) 4(x-6)<2
2) 7n+19<8
3) 3(11+x)>=15
4) 4n-12<6
5) 2n+14>=1
6) 2(x+7)>=10
7) 11n-3>9
8)8x+4<=13
9)5n+16>=9
10) 4(x+2)<14
