an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
632=.60 x (it is important to convert the percentage to decimal by dividing by 100)
632/.60=x
x= 1053.33
x is your original price
the actual answer is 1053.3333(3 repeating) but since it is money you cut it off at 2 decimal points.

Answer:
We need to sketch the problem first.
Find the size of angle R.
One member travels a distance of 12km due north. Another team member heads 50degree east of north and travels a distance of 10km.
If se substute 50° of 180 we have
180-50=130°
The distance between the two team members is the missing side.
We know two sides and included angle, so we use the cosine rule.
A2+b2+c2-2bcCosA
= 102+122-(2x10x12xcos130°)
=100+144-(-147.08)
=100+144+147.08
=391.08
A==SQRT391.08
=19.775
19.7km

Answer:
301.44
Step-by-step explanation:
4*4*3.14*2=100.48
8*3.14*8=200.96
100.48+200.96=301.44
