a. The amount remaining in the account after x week is 700 - 40x
b. Olivia can withdraw can withdraw money from her account money for approx. 13 weeks.
Let x represent the number of weeks. Then the amount of withdrawal in this time is 40x
So, the amount remaining in the account after x weeks is 700 - 40x
Since he needs 150$ in the account for safety net, we must have
700 – 40x ≥ 150
So,
700 - 150 ≥ 40x
550 ≥ 40x
550/40 ≥ x
x ≤ 13.75
Hence, he can withdraw money for approx. 13 weeks.
What is withdraw?Withdrawal involves removing money from a bank account, savings plan, pension or trust.

if 124 people attend a concert and tickets for adults cost $2.5 while tickets for children cost $2 and total receipts for the concert was $274, how many of each went to the concert?
Answer: (52,72) (52 adults and 72 children)
Step-by-step explanation:
1) Create 2 formulas that show the information show above, 2.5x+2y=274 showing how the x is how many adults paid for a ticket and y is how many children paid for a ticket. The second formula being x+y=124 meaning the combination of children and adults equal 124 people.
2) Take those formulas and input them into a graph as shown in the picture (Graph 1)
3) Find the common point shown on the graph (should be the middle grey dot if on Desmos as shown (Graph 2)
4) The common point is (52, 72)
And if you plug these numbers in by replacing the x's and y's i shown in step 1 they bring an output of 274 and 124

Find the reminder when 2 to the 100th power is divided by 5 explain your work
The reminder of 2 to the 100th power divided by 5 is 1
What is the reminder when 2 raised to the power of 100 is divided by 5?2 to the 100th power is:
[tex]2^{100}[/tex] = 1,267,650,600,228,229,401,496,703,205,376
Then dividing 2 to the 100th power by 5:
1,267,650,600,228,229,401,496,703,205,376 / 5 = 253,530,120,045,645,880,299,340,641,075 (without considering the decimal value)
This tells us how many times 5 can divide 2 to the 100th power.
Next, we need to multiply the answer obtained from the division by 5 (since we used 5 to divide):
253,530,120,045,645,880,299,340,641,075 x 5 = 1,267,650,600,228,229,401,496,703,205,375
Lastly, subtracting our last answer from the value of 2 to the 100th power will give us the reminder:
1,267,650,600,228,229,401,496,703,205,376 - 1,267,650,600,228,229,401,496,703,205,375 = 1
Therefore, the reminder when 2 raised to the power of 100 is divided by 5 is 1.

Answer the question below
Suppose that 13 inches of wire costs 52 cents.
At the same rate, how many inches of wire can be bought for 36 cents?
Answer:
9 inches
Step-by-step explanation:
Set it up like a fraction ratio and solve for x. as the price (denominator) and amount (numerator) have a set ratio, you can cross-multiply for your answer.
[tex]\frac{13}{52} =\frac{x}{36\\}\\[/tex]
13*36 = 468
468/52 = 9
Another way would be to divide 13 by 52 and multiply by 36, but then you end up with decimals and cross multiplication will be easier in the long run.

Always that we have an integer, let's say 2, we can rewrite it like:
[tex]\frac{2}{1}[/tex]This will help us when multiplying fractions. To multiply two fractions, we simply multiply the numerator with the numerator and denominator with denominator. In this case:
[tex]\begin{gathered} 2\times-\frac{7}{4}=\frac{2}{1}\times-\frac{7}{4}^{} \\ \\ -\frac{2\times^{}7}{1\times4} \end{gathered}[/tex]And then solve:
[tex]-\frac{2\times^{}7}{1\times4}=-\frac{14}{4}[/tex]Now we can further simplify this fraction, because 14 and 4 are divisible by 2, then:
14 = 2 x 7
4 = 2 x 2
Then the final answer is:

The graph of the equation y = –12x – 6 is attached in the solution.
We can find the x and y intercept of the line to find make the graph.
Putting x = 0 in the given equation, we get:-
y = -12(0) - 6 = 0 - 6 = -6
Hence, the x -intercept is (0,-6).
Putting y = 0 in the given equation, we get:-
0 = -12x - 6
6 = -12x
x = 6/(-12)
x = -1/2
Hence, the y -intercept is (-1/2,0).
We can find another point on the line.
Putting x = -1 in the given equation, we get:-
y = -12(-1) - 6
y = 12 - 6 = 6
y = 6
Hence, another point on the line is (-1,6).
Plotting these points we can graph the equation of the line.

The powers of the imaginary number i have four possible values: 1, i, -1, and -i. Let's see some examples:
i⁰ = 1 (any number with the exponent 0 equals 1)
i¹ = i (any number with the exponent 1 is the number itself)
i² = -1 (this follows from the definition of the imaginary number, the square root of -1)
i³ = i² * i = -1 * i = -i
Now, the results start to repeat from 1 to -i:
i⁴= i² * i² = (-1) * (-1) = 1
i⁵ = i⁴ * i = 1 * i = i
i⁶ = i * i⁵ = i * i = i² = -1
i⁷ = i⁶ * i = -1 * i = -i
From that, we can follow the steps below to find the value of a power of i:
• divide the exponent by 4;
,• if the rest of the division is 0, then the power equals ,i⁰ = 1,;
,• if the rest of the division is 1, then the power equals ,i¹ = i,;
,• if the rest of the division is 2, then the power equals ,i² = -1,;
,• if the rest of the division is 3, then the power equals ,i³ = -i,.
So, for the power i⁶⁴⁹, the exponent is 649. Following the steps above, we find:
• 649/4, has a quotient of 162 and the, rest 1,. Therefore:
i⁶⁴⁹ = i¹ = i
Thus, i⁶⁴⁹ equals i.

To answer the question, we have to understand the different parts of an algebraic expression
An expression containing variables, numbers, and operation symbols is called an algebraic expression. is an example of an algebraic expression. Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
We are given the algebraic expression:
[tex]\frac{3p^2}{5}+8(24-2p)[/tex]For the given question
The difference means the result of subtracting one number from another or How much one number differs from another, so we have
[tex]24-2p\text{ representing Difference}[/tex]Then
The coefficient is is a number or any symbol representing a constant value that is multiplied by the variable of a single term or the terms of a polynomial, so we have
[tex]3\text{ representing coefficient}[/tex]Also
A quotient is a number resulting from the division of one number by another, so we have

D. 16 2/3
E. 17 1/2
If Katerina completes a 15-mile run in 2 1/2 hours. She will complete a mile in an average of five minutes. Option B is correct.
What is average?It is described as a single number that indicates either the closed value for each entry in the set of data or the mean value for the entire set of data.
It is given that, In 2 1/2 hours, Katerina completes a 15-mile run.
We have to find the average number of minutes it takes her to run 1 mile.
15 miles = 2 1/2 hours
15 miles=5/2 hours
The unitary approach allows us to calculate the value of a single unit and then use that value to calculate the value of the required number of units.
1 miles= 5 /30 hours
1 miles = 1/6 hours
As we know that 1 hour consists of 60 minutes.
1 hours = 60 minute
1 mile = 60 / 6 minutes
1 miles = 10 minute
Thus, the average number of minutes it takes her to run 1 mile will be 10 minutes. Option B is correct.
