Answer:
t = 8.31 years
Step-by-step explanation:
This is compound growth with a growth rate of 5%, initial count of 600 and final count of 900.
The appropriate equation is P = Po (1 + 0.05)^t, where t represents the number of years required for the population to reach P:
900 = 600 (1.05)^t. Let's solve this for t:
Dividing both sides by 600, we get 900/600 = 1.05^5, or
1.5 = 1.05^t.
To solve for t, take the log of both sides:
ln 1.5 = t*ln 1.05, or
t = (ln 1.5) / (ln 1.05)
This evaluates to t = 8.31 years.
Answer:
20
Step-by-step explanation:
using the given formula:
V = 1/3(Base Area)(height)
V = 1/3 (5)(12)
V = 1/3 (60)
V = 20
Answer:
B) A bank withdrawal of $40 And a Deposit of $40 .
Resultant is ZERO.
Step-by-step explanation:
If equal is subtracted from equals, the resultant is ZERO.
Here,
A) Two 10 Yard gains in a football game
.
It implies that total gain as +20 yard gains.
⇒ Resultant is NOT ZERO.
B) A bank withdrawal of $40 And a Deposit of $40
Total amount in bank = Total Deposit - Total Withdrawal
= $20 - $20 = 0
⇒ Resultant is ZERO.
C) A change in temperature from -7 °F to 7 °F
Total change in temperature = Initial temperature- Final Temperature
= 7 °F - (-7 °F) = 14 °F
⇒ Resultant is NOT ZERO.
D) Making $50 babysitting then spending half
It implies that total gain as + $50 in money.
⇒ Resultant is NOT ZERO.
First convert all of the fractions into the same denominator. 1/3 = 2/6. Add the new fraction of history books and the fraction for english books. 2/6 + 1/6 = 3/6. Subtract the total from 1 or 6/6. 6/6 - 3/6 = 3/6. The answer is 3/6 or 1/2 when reduced. 50% or 1/2 of the books are science books.
Step-by-step explanation:
