Which shows the expression below in simplified form?
(5.5 × 10^-6) - (3.7 × 10^-7)
A.
1.8 × 10^-6
B.
1.8 × 10^-7
C.
5.463 × 10^-6
D.
5.13 × 10^-6
Answer:
Option D.
Step-by-step explanation:
The given expression is [tex](5.5\times 10^{-6})-(3.7\times 10^{-7} )[/tex]
We have to write it in the simplified form.
[tex](5.5\times 10^{-6})-(3.7\times 10^{-7} )[/tex]
= [tex](5.5\times 10^{-6})-(0.37\times 10^{-6} )[/tex]
= (5.5 - 0.37)×[tex]10^{-6}[/tex]
= 5.13×[tex]10^{-6}[/tex]
Option D will be the answer.

What are Factors of a Number?
Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder
Given data ,
Let the number be A = 18
Now ,
The factors of 18 are = 1 , 2 , 3 , 6 , 9 and 18
The factor pairs of 18 is given by
Factor pairs are the two numbers that, when multiplied, give the number 18.
Therefore, pair factors of 18 are (1,18), (2,9), and (3,6)
The prime factorization of 18 is
Prime Factorization of 18 = 2 × 3²
The first 5 multiples of 18 is = 18 , 36 , 54 , 72 , 90
Hence , first 5 multiples of 18 are 18 , 36 , 54 , 72 , 90 and the factors of 18 are 1 , 2 , 3 , 6 , 9 and 18

a swimming pool has 500 gallons of water in it and is leaking. the change in the amount of water in the pool is -3 gallons per hours. how many gallons of water will the pool contain after 6 hours show your work
The swimming pool will contain 482 gallons of water after 6 hours.
Explanation:To find out how many gallons of water the pool will contain after 6 hours, we can use the formula: Volume = initial volume + rate of change * time. In this case, the initial volume is 500 gallons, the rate of change is -3 gallons per hour, and the time is 6 hours.
Using the formula, we have: Volume = 500 + (-3 * 6) = 500 - 18 = 482 gallons.
Therefore, the pool will contain 482 gallons of water after 6 hours.

If you can buy 1⁄3 of a pound of turkey for 4 dollars, how much can you purchase for 10 dollars? Write your answer as a fraction of a pound.
Answer:
[tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1 such as 3 meter per second or 4 miles per hour.
As per the statement:
If you can buy 1⁄3 of a pound of turkey for 4 dollars
by definition of unit rate we have;
[tex]\text{Unit rate per dollars} = \frac{\frac{1}{3} }{4} = \frac{1}{12}[/tex] pound of turkey.
We have to find how much can you purchase for 10 dollars.
[tex]\text{Weight of turkey for 10 dollars} = \text{Unit rate per dollars} \times 10[/tex]
⇒[tex]\text{Weight of turkey for 10 dollars}=\frac{1}{12} \times 10 = \frac{5}{6}[/tex] pound
Therefore, [tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars

An expression like (3+5) × (4-1) is a combination of numbers and at least one operation. The expression can be simplified by performing the operations in the parentheses first, then applying the multiplication operation.
Explanation:An expression like (3+5) × (4-1) is a combination of numbers and at least one operation. In this expression, the numbers 3, 5, 4, and 1 are combined using the addition and subtraction operations. The addition operation is represented by the symbol '+', and the subtraction operation is represented by the symbol '-'. The expression can be simplified by performing the operations in the parentheses first, then applying the multiplication operation:
(3+5) × (4-1) = 8 × 3 = 24

Write 1/1,024 as an expression using a negative exponent other than -1
Answer:
[tex]\frac{1}{2^{10}}=2^{-10}[/tex]
Step-by-step explanation:
[tex]\frac{1}{1024}[/tex]
To get the expression with negative exponent , we need to convert the number 1024 in exponential form
[tex]1024= 2^5 \cdot 2^5= 2^{10}[/tex]
Replace the denominator by 2^10
[tex]\frac{1}{2^{10}}[/tex]
Now we apply exponential property
[tex]\frac{1}{a^m} =a^{-m}[/tex]
[tex]\frac{1}{2^{10}}=2^{-10}[/tex]
negative exponent other than -1 is [tex]\frac{1}{2^{10}}=2^{-10}[/tex]
