Simple interest is computed using ...
... I = Prt . . . . . where P is the principal amount, r is the interest rate, and t is the lenght of time
The balance in the account is the principal plus the interest:
... P + I = P(1 + rt)
That balance is $2500, so we have
... $2500 = P(1 + 0.054·6) = 1.324P
... $2500/1.324 = P ≈ $1,888.22
The amount that must be deposited now is $1,888.22 in order for the balance to be $2,500 in 6 years.
Answer:
5
Step-by-step explanation:
(a + (1/a)2 = a2 + (1/a2) + 2
⇒ (a + (1/a))2 = 23 + 2
⇒ (a + (1/a))2 = 25
⇒ a + (1/a) =
⇒ a + (1/a) = 5
a3+b3=
(a+b)
(a2−ab+b2)
where a=a
and b=1/a.
so sum it up u get -1
pi = 3.14...
pi^2 = 9.86...
3^2 = 9
4^4 = 16
Pi is between sqrt(9) and sqrt(16).
Answer: 90%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 9/10 as a percent, we need to find a fraction
equivalent to 9/10 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have 
.
Now, we can use cross-products to find the missing value.
So we have (9)(100) which is 900 <em>is equal</em> to (10)(n) or 10n.
So we have 900 = 10n.
Next, dividing both sides of the equation by 10, we have <em>90 = n</em>.
So, 9/10 is equal to 90/100 or 90%.
The main formula of a suface area of a cube is as follow:
A = 6x a², where a is the edge length
if a= 1.5, so A= 1.5² x 6= 13.5
so the answer is A= <span>13.5</span>
