522 to base two
(i'm struggling so bad with math :,))
Answer: 1000001010 base 2
=======================================================
Explanation:
There are two methods to solving this problem.
One method is to involve having a list of the powers of 2
2^0 = 12^1 = 22^2 = 42^3 = 8And so on.
In that list should be 2^9 = 512. So 512 is a power of 2. It is the largest such power that is just under 522. Subtracting it off gets us
522-512 = 10
So that explains why the 2^9 slot in the answer is a '1'. This is the first '1' mentioned in the answer shown above. Then we have a string of '0's until we reach 1010 at the end. That long string of 0s indicate that we don't have any of the following powers: 2^8, 2^7, 2^6, 2^5, 2^4
It's when we get to 2^3 is when we finally have a power of 2 to add on.
Then note how 10-2^3 = 10-8 = 2
So the last term we need to add on is 2^1 = 2. Note the gap from 2^3 to 2^1 because of the first 0 in 1010
So that's how we end up with 1000001010 as our final answer.

The scale of a map says that 4 cm represents 5 km. a. what distance on the map (in centimetres) represents an actual distance of 4 kilometres? b. What is the actual number of kilometres that is represented by 5 centimetres on the map?
Answer:
a. 3 cm
b. 6 km
Step-by-step explanation:
to be completely honest, I just shoot my answer based on the pattern.
if you notice that when the scale is 4 cm, the actual distance is 5 km. When the distance is 4 km, the scale should probably be 3 cm. It's the same with the 5 cm scale, then the distance should be 6 km
Step-by-step explanation:
Use ratios to solve it
a)
4 cm → 5 kmx cm → 4 kmx = 4*4/5 = 3.2 cm
b)
4 cm → 5 km5 cm → x kmx = 5*5/4 = 6.25 km
9) One baseball team played 34 games throughout their entire season. If this baseball team won 22 of those games, then what percentage of their games did they win? Round your answer to the nearest tenth if necessary.
10) At a local department store, slacks have been reduced to $27. This price is at 69.2% of the original price for slacks. Given this, what was the original price of the slacks? Round your answer to the nearest whole number if necessary.
Answer:
9): 64.7
10): 39$
Step-by-step explanation:
Answer:
64.7% and $39
Step-by-step explanation:
Question 9:
This means that the baseball team won 22/34 of their games through their entire season. In order to find the percentages of game they won, you divide 22 by 34, which comes out to 0.64705..., which becomes 64.705%. Rounding this to the nearest tenth, this percentage becomes 64.7%. Therefore, the percentage of games their baseball team is 64.7%.
Question 10:
We can represent this problem as the proportion:
[tex]\frac{27}{69.2} =\frac{x}{100}[/tex]
with x being the original price of the slacks.
We cross multiply to solve this equation. 27 times 100 is 2700. Next, we divide 2700 by 69.2, which comes out to 39.017341. Rounding this to the nearest whole number, this value comes out to 39. Therefore, the original price of these slacks is $39.

How long will mischievous be after 4 weeks?
Answer:
Step-by-step explanation:
So if mischievous grows 8 7/12 inches every week, you have to multiply 8 7/12 times 4 (for the 4 weeks).
8 7/12 x 4= 34 4/12
Then add that to the snakes current length.
34 4/12+ 17 2/9=///
1) Change the fractions to have common denominators
4/12 x 3= 12/36
2/9 x 4= 8/36
2) Add. 8+12= 20. Denominators stay the same. 20/36.
3) Add the whole numbers. 34+17=51.
4) Put it all together. 51 20/36.
5) Simplify the fractions. 20 and 36 can be divided by 4.
20/4=5 36/4=9, 5/9
So, 34 4/12+17 2/9= 51 5/9
Mischievous will be 51 5/9 inches after 4 weeks.
To convert into feet, divided 51 by 12.

Suppose the probability of being picked first in your class is 0.05. What are the the odds of being picked first? Express your answer in the form a:b
Suppose the probability of being picked first in your class is 0.05. The odds of being picked first expressed in form of a: b is 1 : 19.
A probability is a number that represents the possibility or chance that a specific event will occur.
[tex]{\mathbf{\text{The probability of an event} = \dfrac{\text{number of desired outcome}}{\text{total number of possible outcome}}}[/tex]
From the given information;
Let assume the total number of people in the class is whole = 1∴
The odds of being picked first can be computed as:
[tex]\mathbf{=\dfrac{0.05}{1-0.05}}[/tex]
[tex]\mathbf{=\dfrac{0.05}{0.95}}[/tex]
[tex]\mathbf{\dfrac{1}{19}}[/tex]
= 1 : 19
Therefore, the odds of being picked first in terms of a: b is 1 : 19

5. Kathy plans to purchase a car that
depreciates (loses value) at a rate of 14% per
year. The initial cost of the car is $21,000.
How much will the car be worth
in 6 years?
Answer:
At the end of the 1st year you have 21,000-0.14(21000)
= (1-0.14)21000 = 0.86(21,000)
So after three years you have 21000(0.86)(0.86)(0.86)
= 21000(0.86)^3
Answer:
3360
Step-by-step explanation:
Find 14% of 21,000 then multiply by six which gives you 17,640. Then you subtract 21,000-17640. that is your answer.

If a seed is planted, it has a 95% chance of growing into a healthy plant.
If 7 seeds are planted, what is the probability that exactly 3 do grow? Round to 4 decimal places.
If 7 seeds are planted, the probability that exactly 3 do grow is;
P(X = 3) = 0.0002
This is a binomial probability distribution problem where;
P(X = x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾
We are given;
p = 95% = 0.95
q = 1 - p
q = 1 - 0.95
q = 0.05
Thus If 7 seeds are planted, the probability that exactly 3 do grow is;
P(X = 3) = ⁷C₃ × 0.95³ × 0.05⁽⁷ ⁻ ³⁾
P(X = 3) = 35 × 0.857375 × 0.00000625
P(X = 3) = 0.000187
To four decimal places gives;
P(X = 3) = 0.0002
