John currently has $500 in his lunch account. He spent $15 each day on lunch. In how many days will John have $245?
Answer:
18 days.
Step-by-step explanation:
Step 1) Building an arithmetic sequence
We can build an arithmetic series with the given information.
The [tex]n[/tex]th term of an arithmetic series is given by the formula [tex]a_n = a_1 + (n - 1)d[/tex] .
[tex]a_1 = 500\\d = -15\\\to a_n = 500 - 15(n - 1) = 515 - 15n[/tex]
Step 2) Finding the n for which a(n) = 245
As this step's title implies, we need to solve the equation [tex]a_n = 245[/tex]:
[tex]515 - 15n = 245 \text{ / Subtract 245}\\515 - 15n - 245 = 245 - 245\\\to 270 - 15n = 0 \text{ / Add 15n}\\270 - 15n + 15n= 0 + 15n\\\to 270 = 15n \text{ / Divide by 15}\\\frac{270}{15} = \frac{15n}{15}\\\to 18 = n[/tex]
John will have $245 in 18 days.
Answer:
17 days
Step-by-step explanation:
Since John starts with $500 and each day, he’ll spend $15 on lunch. This means that:
On his first day, he’ll spend $15.On his second day, he’ll spend another $15 which is total spend of $30 ($15 x 2)On his third day, he’ll spend total of $45 ($15 x 3)Therefore, on his nth day, he’ll spend $15n where n represents the day. The problem can be modeled into an equation of [tex]\displaystyle{500-15n=245}[/tex] since we will be finding how many days it will take to reach $245.
Then solve for n-term which we determines as the day variable:
[tex]\displaystyle{500-15n-245=0}\\\\\displaystyle{255-15n=0}\\\\\displaystyle{255=15n}\\\\\displaystyle{n=17}[/tex]
Therefore, on his 17th day, he’ll have $245. Hence, the answer is 17 days.

Which expression is equivalent to 5(2.47y − 2.03)?
12.35y + 10.15
12.35y − 10.15
12.35y + 2.03
12.35y − 2.03
Answer:
b) 12.35y − 10.15
Step-by-step explanation:
Given equation,
→ 5(2.47y − 2.03)
The equivalent expression is,
→ 5(2.47y − 2.03)
→ 12.35y − 10.15
Hence, option (b) is correct.
Answer:
[tex]\bf 12.35y-10.15[/tex]Step-by-step explanation:
[tex]\sf 5(2.47y - 2.03)[/tex]
Apply the distributive law:- [tex]\sf a\left(b-c\right)=ab-ac[/tex]
[tex]\sf 5\left(2.47y-2.03\right)[/tex]
[tex]\sf 5\times \:2.47y-5\times\:2.03[/tex]
Multiply the numbers:-
[tex]\sf 5\times\:2.47=[/tex]
[tex]\sf 12.35[/tex][tex]\sf 5\times \:2.03=[/tex]

Given statement solution is :- The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.
To find the median of the given data set, we need to arrange the values in ascending order:
0, 0, 1, 2, 3, 4, 4, 5, 7, 8

Referring to the table below, find the probability that a worker
contacted at random will be 35 - 44 years old. Express the answer as a
decimal rounded to the nearest hundredth and as a percent.
Answer:
A; .31 + 31%
Step-by-step explanation:
What I did: I put 17,172 over 55,208 as a fraction and to get the percentage I compared the denominator to 100, after this you multiply 17,172 by 100 then divide that by 55,208 to get 31.1316147 which rounds out to 31, once you put that over the 100 that is the percentage ( I may not have explained it the best way possible or the most efficient method, but thats how I got my answer ).
Here is what I did:
……17,172……………?…………….….17,172 x 100 = A
—————— = ————…………..A/55,208 = ? ...55,208………….100…………..…..(? = 31.1316147)

The mean of the dataset is 3.55
How do determine the mean?
The dataset is given as:
0 | 3, 8
1 | 0, 1, 4, 7,
2 | 2, 4, 5
3 | 5 0
Remove the stems
3, 8
0, 1, 4, 7,
2, 4, 5
5 0
The mean is then calculated as:
Mean = Sum/Count
So, we have:
Mean = (3 + 8 + 0 + 1 + 4 + 7 + 2+ 4 + 5 + 5 + 0)/11
Evaluate
Mean = 3.55
Hence, the mean of the data is 3.55

Any help please, Question below.
Answer:
No, the slope with the equation is 1/5 and the slope of the table is 2/1 or 2
Step-by-step explanation:
Slope is the change in y over the change in x.
Equation
y = mx + b when an equation is written in the slope intercept form of a line, the m is the slope.
y = [tex]\frac{x}{5}[/tex] - 3 can be writing
y = [tex]\frac{1}{5}[/tex] x - 3 It is easier to see that the slope is [tex]\frac{1}{5}[/tex]
Table
Look at the y's. The are change by 2 each time. Now, look at the x's. They are changing by 1 each time. So, the slope is:
[tex]\frac{2}{1}[/tex] or just 2
Gabrielle and John each wrote the prime factorization of 64 .Analyze their work and explain any errors
Answer:
Gabrielle: What Gabrielle did was use a factor tree to factor out the prime numbers. 64=8*8, then Gabrielle found the factors for 8, 2 and 4. And 2 is prime so now Gabrielle will factor 4 which is 2 and 2. 2 is prime so he stopped there. Then he multiplied all of the prime numbers to get 64
John:
What John did was find factors for 64 with at least one prime number. 2 is prime so he did 2*32, left the two there and factored out 32 using a prime number which was to. 2*2*16, factor out sixteen, 2*2*2*8 then factor out 8. 2*2*2*2*4, factor out 4, 2*2*2*2*2
