Well $2 a month and she is paying for 6 months. So you multiply 6*2=12.
Answer:
Equation of given circle :- x² + y² = 4
Step-by-step explanation:
The equation of the circle with center (0, 0) and radius r is given by,
x² + y² = r²
It is given that, a circle with center (0,0) and (-1,-3) a point on the circle
To find the radius of circle
radius r = √[(0 - - 1)² + (0 - -3)²] =√(1 + 3) =√4 = ±2
r = 2
<u>To find the equation of circle</u>
x² + y² = r²
x² + y² = 2²
x² + y² = 4
Answer:
The balance in the account after 20 years will be $11280.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
.
In this problem
We want to find T, when 
The first step is find the earnings due to interest. So
Adding to the principal to find the balance
The balance in the account after 20 years will be $11280.
Answer:
12.5%
Step-by-step explanation:
sum the parts of the ratio 1 + 3 + 4 = 8 parts
8 parts represents 100%, hence
1 part = 
= 12.5% ← Andy's percentage of the total
1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850
so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons
0.25 x 850 = 212.5
1.5 x 850 = 1,275
2.5 x 850 = 2,125
1b) the unit rate is 850
1c) 5.5 x 850 = 4,675 gallons
1d) So 850 gallons can be filled in an hour, you only need 100 gallons
850/100 = 17/2 (simplified)
17 gallons/hour 60 minutes
------------------------- x ---------------------
2 gallons 1 hour
the gallons cancel out and the hours cancel out which leaves us with:
17 x 60 = 1,020 / 2 = 510
510 minutes
2) I don't know how to do two sorry
