To find the common difference in the sequence 8, 16, 24, 32.... we must find what the difference between two consecutive terms is. A simple way to do this is to find the difference between the first term and the second term. That means that we have to do the second term - the first term. That means we do 16 - 8 which gives us that the common difference is 8.
Answer:
3.73
Step-by-step explanation:
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:


using cosine rule:


Answer:
Answer is after 20 miles
Step-by-step explanation:
10 +2.5x = 3x
10 = 3x-2.5x
10=0.5x
10/.5=x
x=20
At 20 miles they both have a cost of 60
