<u>Given</u>:
The arc length for the given sector is 7π
The central angle for the given sector is θ
The radius of the circle is r.
We need to determine the formula for r in terms of θ
<u>Formula for r:</u>
The formula for r in terms of θ can be determined using the arc length formula,
Substituting the values, we have;
Dividing both sides by θ, we get;
Thus, the formula for r in terms of θ is 
The price will be reduced by 20%, so will become 0.8x
The tax will increase the amount by 0.0625 times
Thus:
A = 0.8x + 0.0625x
A = 0.8625x
I'm in a hurry to get home.
My car is almost out of gas.
I pull into a gas station.
I have $10 in my pocket.
Gas is selling for $2.36⁹ per gallon.
How many gallons can I buy.
=================================
Even better:
My car gets 25 miles to the gallon.
How many miles can I buy ?
Answer: 50a+2
Step-by-step explanation:
1. Simplify 5a5a\5a5a to 1.
1+5×10a+10
2.Simplify 5×10a to 50a.
1+50a+10
3.Cancel 10.
1+50a+1
4. Collect like terms.
50a+(1+1)
5. Simplify.
50a+2
1% is the answer because you have to bump it up two place and it is always the first number.
