Answer:
It is a geometric sequence en the common ratio is: 
.
Step-by-step explanation:
1. By definition, a geometric sequence is a sequence in which you obtain a term by multiplying the previous one by a common ratio.
2. The common ratio is obtained by dividing a term by its preceding term.
3. Keeping this on mind, you have:
4. As you can see, the common ratio is 
The answer is 11.265408 km.
To calculate the number of kilometers, we will use several conversions:
A) 1 mi = 63,360 in
B) 1 in = 2.54 cm
C) 1 cm = 0.00001 km
A) 1 mi = 63,360 in
7 mi = 63,360 in · 7 = 443,520 in
B) 1 in = 2.54 cm
443,520 in = 2.54 cm · 443,520 = 1,126,540.80 cm
C) 1 cm = 0.001 km
1,126,540.80 cm = 0.00001 km · 1,126,540.80 = 11.265408 km
Answer:
A: Diane earns 200 + (10×20)= 400
B: Darryl earns (400-250)/20= $7.50 per hour
Answer:
Step-by-step explanation:
This is because we subtract 456 from each side.
We then divide the whole equation by <em>x</em> .
Adding 50 to both sides gives us <em>x</em> by itself, hope this helps :D
