Answer:
4594.76 USD will be in the account on Burt's 18th birthday.
Step-by-step explanation:
Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:
(1)
Where:
- Initial amount, measured in US dollars.
- Current amount, measured in US dollars.
- Annual interest rate, measured in percentage.
- Time, measured in years.
If we know that , and , then the money in the savings account on Burt's 18th birthday is:
4594.76 USD will be in the account on Burt's 18th birthday.
Answer:
9.16
Step-by-step explanation:
We know that
Total expense = price of sugar * consumption
let price of sugar was 100
So total expense = 100*10=1000
But now new expense =1100 (I,e.10% more than 1000)
and new price =120(i,e. 20% more than 100)
So new consumption = new expense/ new price=
1100/120
=110/12
=9.16

Answer:
y - (-7) = 7(x - 4)
Step-by-step explanation:
The given points are (4. -7) and (5, 0).
The point-slope equation of a line is
y - y1 = m(x - x1),
where (x1, y1) is a point on the line, and m is the slope.
m = (y2 - y1)/(x2 - x1) = (-7 - 0)/(4 - 5) = -7/(-1) = 7
You can use either point for (x1, y1). I will use point (4, -7).
y - (-7) = 7(x - 4)
Answer:
C. 36π
Step-by-step explanation:
The formula for volume of a sphere is:
V=⁴/₃πr³
We are given diameter: 6
To convert to radius, divide by 2.
6÷2=3. R=3
Plug in to formula
V=⁴/₃π3³
Simplify with multiplication
V=⁴/₃π27
V=36π
