Rules in exponents:
Let's review few rules before solving.
x⁰ = 1 (x can be any number)x⁻ⁿ (n ≠ 0 or any number below 0) = 1/xⁿSolution (9):
3⁻² = 1/3² = 1/9Solution (11):
(-5)⁻²=> 1/(-5)²=> 1/-5 x -5=> 1/25Solution (15):
-3⁰ = 1 [x⁰ = 1]Solution (17):
1/2⁰ = 1/1 = 1Solution (26):
k⁻⁴j⁰ => k⁻⁴ x j⁰ => k⁻⁴ x 1=> k⁻⁴ = 1/k⁴Solution (36):
7s⁰t⁻⁵/2⁻¹m²=> 7 x s⁰ x t⁻⁵/2⁻¹ x m²=> 7 x 1 x t⁻⁵ x 2/m²=> 14 x t⁻⁵/m²=> 14t⁻⁵m⁻²Hoped this helped!
Answer:
Step-by-step explanation:
(ab)^n = a^n*b^n
so (-a)^n = (-1)^n*a^n
a^(-n) = 1/a^n
a^0 = 1 if a is not 0
9. 3^(-2)
= 1/3^2
= 1/9
11. (-5)^(-2)
= (-1)^-2*5^(-2)
= (1/(-1)^2)*(1/(5^2))
= 1/1*1/25
= 1/25
15. -3^0 = 1
17. 1/2^0
= 1/1
=1
26. k^(-4)*j^0
=(1/k^4)*1
=1/k^4
36. 7*s^0*t^(-5) / 2^(-1)*m^2
= 7*1*(1/t^5) / (1/2)*m^2
= 2*7 / t^5*m^2
= 14 / t^5*m^2

Which model shows 1/2 times 1/3
Answers
Answer:
Where's the model?
Hai there!
First, let's use the KCF technique (my old math teacher taught me this!)
Keep the first fraction the same, in this case, 1/2
Change the sign from division to multiplication
Flip the second fraction, or 3/8, to get it's reciprocal, or 8/3.
The new equation should look like this:
1/2 * 8/3
Now multiply straight across like you normally would, like so:
1 * 8 = 8
2 * 3 = 6

It is found that Gross income was more than the larger of $1,050
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given that Your friend Alice is a full-time college student, earned $4,000 working at the campus bookstore over two semesters last calendar year.
Also he got a part-time job as a cashier in February, earning $9,500.
So, under the age of 65 and not older or blind, you must file your taxes if: Unearned income was more than $1,050.
Earned income was more than $12,000.
Therefore, Gross income was more than the larger of $1,050 or we can say on earned income up to $11,650 plus $350.

y = -8/9
Step-by-step explanation:1)
The first thing you have to do is multiply both sides (opposite of division because it was divided by 5) by 5 to get y by itself on the right side. Your equation will then be 15y-40/60=y.
2)
Then you want to get rid of the divided by 60 on the left side, to do this you have to do the opposite of division which is multiplication. So multiply both sides by 60. Your equation will then be 15y-40=60y.
3)
To combine like terms, you have to bring y to one side, ill just bring the 15y over to the right, we do this by subtracting 15y to both sides (since its positive (+)15y we do the opposite which is subtraction (-). After we do this the equation will be -40=45y.
4)
Now what we are trying to do is get y by itself, so we do the opposite of what it is which is division (we do division because its multiplication 45y is 45 (times)x y). We divide 45 by both sides and our y is by itself! the new equation is -40/45=y which is our answer!
5)
But we can still simplify! Once the answer is simplified the final answer should be -8/9=y!

PLEASE HELP!!!!!! A spinner is divided into many sections of equal size. Some sections are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 9 over 20. The probability of the arrow landing on a section colored blue is 6 over 20. What is the probability of the arrow landing on a green-colored section?
15 over 20
11 over 20
6 over 20
5 over 20
Answers
This is the same as writing 5/20
====================================================
Explanation:
Instead of saying "9 over 20", I'll write 9/20. The same goes with the other fractions.
The 9/20 probability for red means there are 9 red out of 20 total.
Similarly, the 6/20 refers to 6 blue out of 20 total.
There are 9+6 = 15 sections that are either red or blue, but not both.
This leaves 20-15 = 5 sections for green and it leads to 5/20 as the final answer. We could reduce 5/20 to get 1/4, but it looks like your teacher doesn't want you to reduce the fraction. Sometimes it's handy to not reduce because we see that it's out of 20 spaces total.
Answer:
15/20

of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Express your answer in fraction and decimal form.
Answers
And if that's true then the pears weigh 2.5 kilos.
8.4 total kilograms - 2.5 = 5.9
So the apples would be 5.9 kilograms
Answer:
Total - 8.4 kilos
Pears; 2/5
Apples; Unknown
The rest of the 2/5 of pears is 3/5 apples.
3/5(apples) x 8.4(kilos)
0.6 x 8.4 = 5.04 or 5 4/100 which simplifies to 1/25

Last week, Danielle spent x dollars on lunch, three times as much on transportation as she did on lunch, and $4 less on books than she did on transportation.
Write the expressions for the total amount Danielle spent last week on transportation and books.
If Danielle had $59 to spend last week, what is the greatest amount she could spend on lunch?
Answers
Danielle spent three times as much on transportation as she did on lunch, so we can call this 3x.
She spent $4 less than on books than she did on transportation -> 3x - 4
So, she spent x + 3x + 3x - 4 (simplified as 7x - 4).
Danielle had $59 to spend last week -> 7x - 4 = 59
Solve for x : (59+4)/7 = 9
So, she can spend at max $9 on lunch
Recheck : 9 + 27 + 27 - 4 = 63 - 4 = 59.

56, 85, 64, 51, 23, 43, 82, 77, 50 what's the Mean, Median, Mode, Range
Answers
Answer:
Explanation
Step-by-step explanation:
Median is 56.
To calculate median you have to sort the numbers least to greatest and find the middle number sometimes there is 2 when there is an even number for the numbers in the dataset.
Mean 59.
For mean you add up all the scores and then divide them by the number of scores there were but for this case numbers.
56 + 85=141 + 64=205 + 51=256 + 23=279 + 43=322 + 82=404 + 77=481 + 50=531 divided by 9=59
Mode
Is all of them because mode is the number that appears most in the data set and in our data set every number only appears once so all of them>
Range is 62
Because range is highest number subtracting our lowest number so highest number=85
Our lowest number is 23
so 85 - 23=62
Hope this helps have a great day:)
