Write the equation for the word problem
Devon became a waiter at a fancy restaurant. He makes $9 per hour. One night he made $150 in tips. How many hours did he work if he made a total of $226.50.
Answer:
9x + 150 = 226.50
Step-by-step explanation:
Devon makes $9 per hour. So, that signalizes "9x" (x representing the amount of hours he worked)
$150 represents how much he made one night, so you would add that to 9x. (9x + 150)
Finally, it gives you the total amount: 226.50
In conclusion, your equation should be: 9x + 150 = 226.50

Find the discounted price, to the nearest cent, for a portable CD player that sells for $59.95 and is on sale for 30% off
Answer:
To find the discounted price of the portable CD player, we need to multiply the original price by the discount rate and then subtract that amount from the original price.
Discount = 30% of $59.95
Discount = 0.3 x $59.95
Discount = $17.985
Discounted Price = Original Price - Discount
Discounted Price = $59.95 - $17.985
Discounted Price = $41.965
Therefore, the discounted price of the portable CD player is $41.97 to the nearest cent.
Step-by-step explanation:
Pls give brainlist!
Answer:
$41.96
Step-by-step explanation:
To find the discounted price of the CD player, we can start by calculating the amount of the discount.
Discount = 30% of $59.95
Discount = 0.30 x $59.95
Discount = $17.985 or $17.99 (rounded to the nearest cent)
The discounted price of the CD player is the original price minus the discount:
Discounted price = $59.95 - $17.99
Discounted price = $41.96 (rounded to the nearest cent)
Therefore, the discounted price of the portable CD player is $41.96 to the nearest cent.

Answer:
(1.3^9)/(1.3^3)= Last Column: (1.3)^6
(-5/6)^2= First Column: -5^2/6^2
(-5/6)^1: Third Column: -5/6
(1.3)^0: Second Column: 1
Answer:
first row last column, second row first column, third row third column, last row second column
Step-by-step explanation:
first row last column: doing division w/ exponents means you have to subtract the exponents. 9-3=6 and since they have the same base, you don't have to do anything with it, so the answer is the last column.
second row first column: properties show that the square of -5/6 is equal to -5^2/6^2 or 5^2/-6^2. therefore, the answer is the first column.
third row third column: anything to the power of one is itself.
last row second column: anything to the power of zero is one.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:
Answer:
8, 2, 8, 2
7, 3, 7, 3
6, 4 6, 4
9, 1, 9, 1
Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.

In your own words, describe how to find the GCF for a set of numbers. Use the numbers 24 and 32 as an example.
Answer:
4
Step-by-step explanation:
First, you would have to prime factorize both of the numbers. The prime factorization of 24 is 24 = 2*2*3*3, and the prime factorization of 32 is 32 = 2*2*2*2*2 or 2^5. After that, you would find what is most common:
24 = 2*2*3*3
32 = 2*2*2*2*2
What is common is that there is two 2's in each equation. 2*2 is 4, so the answer is 4.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

1. The rule that the Right of Occupancy is based on.
HERE ARE THE NOTES
DAY ONE NOTES
Sovereignty is essentially the power to make laws
Sovereignty refers to having supreme, independent authority over a geographic area, such as a territory.
When discussing Indigenous people’s sovereignty, there is always a connection to a specific area of land. Going back to our definitions, the US Legal definition of the land states, “Sovereignty refers to having supreme, independent authority over a geographic area, such as a territory.” While sovereignty can exist without an explicit connection to a territory, Indigenous sovereignty will ALWAYS reference a specific location.
DAY TWO NOTES
sovereignty is the backdrop through which history must be read in order to provide a real understanding.
Right of Occupancy
“The right of occupancy is not based on a treaty, statute, or other federal government action.”
until that right shall be extinguished by a voluntary cession to our government.
Self-government is right in which a voluntary cession of the right of occupancy cannot extinguish.

The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
