Answer:
1: 5/24
2: 6/10 but in simplist form it is 3/5
3: 4/4 which = 1 whole
4: 11/42
5: 6/2 ( in simplist form) 3/1 or just 3
Step-by-step explanation:
To answer these questions, add or subtract, then simplify if needed.
For simplifying you must find the common denominator
For example:
20/5
The Highest number and only number that can go into both numbers is 5
So 20 ÷ 5 = 4
And 5÷ 5 =1

it has to be positive and it is obviously more than 1 hour so it has to be 8 hours by process of elimination.
(3x2)(−2x4) = 3(−2)x2∙4 = 6x8 can you find whats wrong with this problem
Answer:
the equal sign
Step-by-step explanation:
The final correct result is:[tex](3x^2)(-2x^4) = -6x^6[/tex]
Given that:
The expression: [tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]
The error is in the second step of the simplification:
[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} \\(3x^2)(-2x^4) = 6x^8[/tex]
[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]
The second step is incorrect. The correct rule for multiplying powers with the same base is to add the exponents, not multiply them.
Here, add the power of x is 2 and 4, that is,
2 + 4 = 6
And multiply the coefficient of x as:
The coefficient of x are 3 and (-2).
So, the multiplication as:
3 × (-2) = -6
The correct simplification should be:
[tex](3x^2)(-2x^4) = 3\times(-2) \times x^{2+4}\\(3x^2)(-2x^4) = -6x^6[/tex]
So, the multiplication as:
3 × (-2) = -6
So, the final correct result is:
[tex](3x^2)(-2x^4) = -6x^6[/tex]
Hence, the error occupied in second step.

6 to the second power−2(5+1+3) equals?
Answer:
306
Step-by-step explanation:
6² = 36
36 - 2 = 34
Since 5+1+3 is in parenthesis, it comes before multiplication (remember PEMDAS or Order of Operations)
5+1+3 = 9
34 x 9 = 306

The rule that the Right of Occupancy is based on the fact that the Federal Government cannot grant what it does not have
Due to the Right of Occupancy, the Federal Government cannot grant what it does not own. This means that the Government is not allowed to give or take from others what itself doesn't own. This could consist of someone being in court for any reason, but due to the Right of Occupancy, if the court does not have a warrant to search the suspect's property or belongings, they are not allowed to use the suspect's property against them in court due to the fact that it simply isn't theirs.
How is energy involved in physical change??
Answer:during phase chages
Step-by-step explanation:
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants
Is this right? I chose 15.
Answer:
Correct, it is 15
Step-by-step explanation:
Because 3 turns into 9, you also want to multiply the other by 3, so you’d do 5x3 to get 15
Answer:yes you are correct. The answer is 15
Step-by-step explanation:
You would have to do 9/3=x/5. If you simplify that it would be 3x=45. If you simply further, you would get x=15 so yes you are correct.

Answer:
((ordinal date) +3) mod 7 = weekday number(IFC date) mod 7 = weekday numberno rule is possibleStep-by-step explanation:
a) Ordinal Calendar
The ordinal calendar numbers days of the year sequentially, so any given date is specified only by its day number: 1 to 366. In 2020, Jan 1 was a Wednesday, so the rule needs to be ...
day of week = ((ordinal date) +3) mod 7
This will give a result from 0 to 6. Those numbers map to days of the week as follows:
0: Saturday; 1: Sunday; 2: Monday; 3: Tuesday; 4: Wednesday; 5: Thursday; 6: Friday
__
b) International Fixed Calendar
The international fixed calendar has 13 months of 28 days. The first day of the year is always Sunday, so the day of the week is ...
day of week = (International Fixed Calendar date) mod 7
In 2020, there are two "leap days" that have day number 29. Days numbered 29 have no associated day of the week.
__
c) There is no rule that maps weekday to day of the year. (Each weekday is repeated many times (52 or 53) through the year, so there can be no functional relationship.)

btw i put that on accident
Answer:
C) 54.5
Step-by-step explanation:
to find the constant of this proportional x and y table;
first divide y by x.
eg. 163.5 divided by 3, which results in 54.5
next, to confirm this is our answer, we need to divide y by x once more.
eg. 327 divided by 6, which also results in 54.5

Ziann’s weekly earnings were proportional to the number of hours she worked. This table shows the number of hours Susan worked and the amount she earned.
How much money did Ziann earn per hour?
Answer:
Can't answer.
Step-by-step explanation:
We know that Ziann's earnings were proportional to the hours she worked, but the table shows how much Susan earned, so we don't know how much Ziann earned. We are not told that Ziann and Susan are the same person.
Susan's earnings:
$47.50/(5 hours) = $9.50/hour
According to the table, Susan earned $9.50 per hour.
