Answer:
1,203,650,000 mi³
Step-by-step explanation:
Volume of a sphere is given by V = (4/3)πr³
in this case diameter D, = 1320 mi
radius, r = D/2 = 1320 / 2 = 660 mi
volume V, = (4/3)(3.14) (660)³
= 1,203,649,920 mi³
= 1,203,650,000 mi³ (nearest thousand)
Answer:
Step-by-step explanation:
2x+3y=15
x-3y=18
------------------
x=3y+18
2(3y+18)+3y=15
6y+36+3y=15
9y=15-36
9y=-21
y=-21/9
simplify
y=-7/3
x-3(-7/3)=18
x+7=18
x=18-7
x=11
Answer: x=11, y=-7/3. (11, -7/3).
---------------------------------------------
2x+3y=20
-2x+y=20
----------------
4y=40
y=40/4
y=10
2x+3(10)=20
2x+30=20
2x=20-30
2x=-10
x=-10/2
x=-5
Answer: x=-5, y=10. (-5, 10).
-------------------------------------------
3x-4y=-5
-10x+4y=12
--------------------
-7x=7
x=7/-7
x=-1
3(-1)-4y=-5
-3-4y=-5
4y=-3-(-5)
4y=-3+5
4y=2
y=2/4
simplify
y=1/2
Answer: x=-1, y=1/2. (-1, 1/2).
Answer:
true;)
Step-by-step explanation:
its right
Before we start answering the question, let's define the compound interest formula:
Where:
<span>'A'</span> is the amount of money in dollars
'P' is the principal amount of money in dollars
'r' is the interest rate (decimal)
'n' is the number of times interest is compounded per year
't' is the time in years
<span>
(A) Find Principal Amount</span><u /><span><u>Given:</u>
</span>A = 12,000
P = ?
r = 0.08
n = 2 (semiannually)
t = 5
Now we plug our values in and solve:



∴ You would have to deposit $8106.77 in order to have $12,000 in 5 years from now.
(B) Find Principal AmountSame given values as above, with the exception of 't' which is now 10 instead of 5.



∴ You would have to deposit $5476.64 in order to have $12,000 in 10 years from now.
