Speed= distance /time
distnace=170 miles
t=2 hours + 45 minutes *(1 hora / 60 minutes=2 hours + 0.75 hours=2.75 hours.
Speed=170 mile / 2.75 hours=61.818...miles/hour≈61.8 miles/hour.
Solution: 61.8 miles/hour.
Answer:
1.The radius to circumference formula is: C = 2πr.
2.The formula for radius to area is: A = πr2.
3. If you need to go from radius to diameter, multiply radius times 2 : d = 2r.
Step-by-step explanation:
First, we need to find the GCF (greatest common factor) of each of the number.
1. List out the prime factors of each of them.
2. Multiply the prime factors that the two numbers have in common
60 = 2 × 2 × 3 × 5
84 = 2 × 2 × 3 × 7
The common factors are: 2 and 3
GCF = 2 × 2 ×3
GCF = 12
Factor out 12 from the equation
12(5x - 7)

Step-by-step explanation:
Answer:
It will be worth about £885.59.
Step-by-step explanation:
The art piece originally costs £600.
And it appreciates at a rate of 3.97% each year.
And we want to find the value of the art after 10 years.
We can write an exponential function to model the situation. The standard exponential function is given by:

Where <em>t</em> is the time in years.
Since it appreciates at a rate of 3.97% each year, the value after each year will be (100% + 3.97%) or 103.97%.
103.97% = 1.0397. So, <em>r</em> = 1.0397:

Our <em>a</em> is the initial value. Therefore:

Then the value of the piece of art after 10 years is:

It will be worth about £885.59 after 10 years.
