Answer:
485 × [tex]10^{-10}[/tex]
Step-by-step explanation:
first we need to convert the number to fraction
0.0000000485
[tex]\frac{0.0000000485}{10000000000}[/tex]
it will be
[tex]\frac{485}{10000000000}[/tex]
or can be written as
[tex]\frac{485}{10^{10} }[/tex]
now we need to convert it to scientific notation
485 × [tex]10^{-10}[/tex]

A) Mary read 3 times the amount of books as Carey over the summer. Carey read twice as
many books as Barry. If the students read 405 books combined, how many more books did
Mary read than Barry?
----
Answer:
225
Step-by-step explanation:
Mary = 3x (3 times Carey)
Carey = x
Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)
3x + x + x/2 = 405
4x + x/2 = 405
8x/2 + x/2 (treat these as fractions) = 405
9x/2 = 405
9x = 810 (cross multiply)
x = 90
Mary = 3(90) 270
Carey = 90
Barry = 90/2 45
Mary - Barry
270 - 45 = 225

Answer: 3(x+3) = 3X + 3(x-1)
3x + 9 = 3x + 3x - 3
3x + 9 = 6x - 3
0 = 6x - 3 - 3x - 9
0 = 3x - 12
12 = 3x

a) Cube root of a perfect cube number ending with 8 ends with 8.
b) Cuberootofaperfectcubenumberendingwith6endswith2.
c) Cube root of a perfect cube number ending with three zeroes ends
with one zero.
d) Cube root of a negative number may be positive.
Answer:
b is the correct answer
Step-by-step explanation:
(ii) A perfect cube does not end with two zeros. (iii) If square of a number ends with 5, then its cube ends with 25. (iv) There is no perfect cube which ends with 8.Cube roots of negative numbers are always negative.

Step-by-step explanation:
Use complete sentences to describe why √-1 ≠ -√1
Well let's say that to compare these two numbers, we have to start with the definition first.
Definition
[tex] \displaystyle \large{ {y}^{2} = x} \\ \displaystyle \large{ y = \pm \sqrt{x} }[/tex]
Looks like we can use any x-values right? Nope.
The value of x only applies to any positive real numbers for one reason.
As we know, any numbers time itself will result in positive. No matter the negative or positive.
Definition II
[tex] \displaystyle \large{ {a}^{2} = a \times a = |b| }[/tex]
Where b is the result from a×a. Let's see an example.
Examples
[tex] \displaystyle \large{ {2}^{2} = 2 \times 2 = 4} \\ \displaystyle \large{ {( - 2)}^{2} = ( - 2) \times ( - 2) = | - 4| = 4}[/tex]
So basically, their counterpart or opposite still gives same value.
Then you may have a question, where does √-1 come from?
It comes from this equation:
[tex] \displaystyle \large{ {y}^{2} = - 1}[/tex]
When we solve the quadratic equation in this like form, we square both sides to get rid of the square.
[tex] \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{ - 1} }[/tex]
Then where does plus-minus come from? It comes from one of Absolute Value propety.
Absolute Value Property I
[tex] \displaystyle \large{ \sqrt{ {x}^{2} } = |x| }[/tex]
Solving absolute value always gives the plus-minus. Therefore...
[tex] \displaystyle \large{ y = \pm \sqrt{ - 1} }[/tex]
Then we have the square root of -1 in negative and positive. But something is not right.
As I said, any numbers time itself of numbers squared will only result in positive. So how does the equation of y^2 = -1 make sense? Simple, it doesn't.
Because why would any numbers squared result in negative? Therefore, √-1 does not exist in a real number system.
Then we have another number which is -√1. This one is simple.
It is one of the solution from the equation y^2 = 1.
[tex] \displaystyle \large{ {y}^{2} = 1} \\ \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{1} } \\ \displaystyle \large{ y = \pm \sqrt{1} }[/tex]
We ignore the +√1 but focus on -√1 instead. Of course, we know that numbers squared itself will result in positive. Since 1 is positive then we can say that these solutions exist in real number.
Conclusion
So what is the different? The different between two numbers is that √-1 does not exist in a real number system since any squared numbers only result in positive while -√1 is one of the solution from y^2 = 1 and exists in a real number system.
Answer:
Therefore [tex]\sqrt{1} \neq -\sqrt{1}[/tex]
Step-by-step explanation:
[tex]\sqrt{-1} \\[/tex] cannot be calculated as no two identical numbers that are multiplid could give -1. However - [tex]\sqrt{1}[/tex] means -1 x [tex]\sqrt{1}[/tex] = -1 x 1 = -1 . Therefore [tex]\sqrt{1} \neq -\sqrt{1}[/tex]

Express each number as a product of its prime numbers.
1. 245
2. 510
3. 250
4. 1,089
5. 4,725
6. 900
18. 27,000
Answer:
245 = 5*7*7
510 = 3*17*2*5
250 = 5*5*5*2
1089 = 3*3*11*11
4725 = 3*3*3*5*5*7
900 = 3*3*5*5*2*2
27000 = 3*3*3*5*5*5*2*2*2

5(3)+t(24)= I need help wish me the best of luck
Answer:
15+24t
Step-by-step explanation:
First, I copied the expression down. Then, I used PEMDAS, so I multiplied 5x3. That left 15 + t(24). I just gave the variable to 24, making 24 t's coefficient. So, the simplified answer would be 15 + 24t.

Answer:
h = S/(2 π r) - r
Step-by-step explanation:
Solve for h:
S = 2 π r (r + h)
S = 2 π r (r + h) is equivalent to 2 π r (r + h) = S:
2 π r (r + h) = S
Divide both sides by 2 π r:
r + h = S/(2 π r)
Subtract r from both sides:
Answer: h = S/(2 π r) - r
Answer:
h=s/(2 π r) -r

A bookshop has some fiction and non books. 2/5 of the books are fiction books. Of these, 1/5 are mystery stories. 1/3 of the non fiction books are mystery stories too. What fraction of all the books in the shop are mystery books?
Answer:
1/3 of all of the books
Step-by-step explanation:
5/5 - (2/5 +1/5) =2/5
2/5(1/3) = 2/15 nonfiction mystery books
2/15 + 1/5 = mystery books
1/5 = 3/15
2/15 + 3/15 = 5/15
5/15 = 1/3
The mayor knows the area needed for a flower garden in the park. She wants the base to be a certain length. How can she determine the necessary height to get the correct area of the flower garden? Explain.
Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
Maria would determine the height by dividing the area of the garden by the base
From the question, she has the area and the base.
Also, the garden has the shape of a parallelogram
The area of a parallelogram is the product of the base and the height.
So, when the area is divided by the base, she gets the height

Answer:
The answer will be:
7 2/3
Answer:
The Oringal Answer is 65/8 But In a Simplified Mixed Number the Answer is 8 1/8
Step-by-step explanation:
We need to get rid of parentheses in this term.
All the negative factors will change sign.
In our example, we have only one negative factor.
The sign of the term will change, since there is an odd number of negative factors.
We can reduce this fraction by dividing both numerator and denominator by a common numeric factors.
