3³⁸ - 3³⁷
= 3³⁷(3 - 1)
= 2 * 3³⁷
= 2 / [3^(-37)].
Hence x = -37.
David expressed the ratio of the number of books that he owns to the number of DVDs that he owns as 27:11. Which statement could be true based upon this relationship? David has 11 books and 27 DVDs. David has 11 DVDs and 27 books. David has 11 DVDs and 27 items total. David has 11 books and 27 items total.
Answer: David has 11 DVDs and 27 books.
Step-by-step explanation:
When numbers are put in ratio form they are meant to compare their relative sizes.
The first number will be the first item being compared to the other.
For instance, if you had 2 pens and 3 pencils, the ratio of your pens to your pencils will be; 2:3. The ratio of your pencils to your pens however is 3:2.
In the same vein, a ratio of books to DVDs of 27:11 means that David has 27 books and 11 DVDs.
Answer:
David has 11 DVDs and 27 books.

The equation x^3-3x=1 has a solution between 1.8 and 1.9. use a trial and improvement method to find this solution. give your answer correct to 2 decimal places.
HELPPPPPP I HAVE BEEN TRYING FOR AGES
Answer:
1.88 to 2 decimal places
Step-by-step explanation:
First, I plugged in 1.8 and 1.9:
1.8^3-3*1.8=0.432
1.9^3-3*1.9=1.159
Then, I plugged in 1.85:
1.85^3-3*1.85=0.78
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
Hope this helps!
Answer:
Step-by-step explanation:
1.8=-0.568 is too small
1.9=0.159 is too big
1.87=-0.70797 is too small
1.88=0.004672 is too big
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
1.875=-0.033203125 is too small
so it should be 1.88 to 2 decimal places

Richard has 15 apples. He gave Pam 5/2 of them to bake a pie. How many apples did he give to Pam?
Answer:
2.5 or 2 1/2 apples.
Step-by-step explanation:
5/2 simplified will be 2.5 or 2 1/2.
If you look into it further, because Richard had 15 apples, you subtract 2 1/2 apples he gave Pam which would leave him with 12.5 or 12 1/2. But really the answer is two and a half apples.

What were the main important ideas in geometry that you studied in the first six weeks?
Answer:
The preceding chapter explored implications of research on learning for general issues relevant to the design of effective learning environments. We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis. A major goal of our discussion is to explore the knowledge required to teach effectively in a diversity of disciplines.

Answer:
1
Step-by-step explanation:
Let's look at the first option in this multiple-choice; 18. 18 is divisible by 18, but is not divisible by 35, so that answer isn't right.
What about 3? 3 is divisible by 18, but it isn't divisible by 35. Let's move on.
7 is divisible by 35, but it isn't divisible by 18.
1 is universally divisible by anything. That doesn't mean it is the greatest common factor, but in this case it is, because none of the other options are a factor of both numbers given. Therefore, 1 is divisible by 18.

A boat is carried with the current at an angle of 43 degrees to the shore. if the river is approx. 15 meters wide, how far does the boat travel before reaching the opposite side of the shore
Answer:
22 m
Step-by-step explanation:
The computation of the how much far does the boat travel is as follows:
sin 43 degrees = 15 ÷ d
d = 15 ÷sin 43 degrees
= 15 ÷ 0.6820
= 21.99
= 22 m
Hence, the how much far does the boat travel is 22 m
We simply applied the above formula so that the correct value could come

2. 12 2/9
3. 11 9/23
4. 12 9/23
Answer:
2. 12 2/9
Step-by-step explanation:
Because of the choices, I assume the three addends are mixed numerals:
3 4/7 + 4 2/9 + 4 3/7 =
= 3 + 4 + 4 + 4/7 + 2/9 + 3/7

= 12 2/9
Answer: 2. 12 2/9

Answer:
40
Step-by-step explanation:
SF of KP to KN = 4
If LM = 32, then we would have to divide 32 by 4 in order to get the missing length of KL.
32 ÷ 4 = 8
Length of KL = 8
Length of LM = 32
Length of KM = 32 + 8 = 40
In a city the population is increasing exponentially at a rate of 1.6% per year.
Find the overall percentage increase at the end of 20 years.
Answer:
32% increase at the end of 20 years
Step-by-step explanation:
If the population increases at a rate of 1.6% per year, we should multiply it by the number of years that passed, which in this case, is 20. When we multiply those, we get 32%.
