n(x) =300(1.04)^x. Which account has the highest value in 5 years? Which account has the highest in 12 years? Show your work!
Answers
Answer:
3(5) + 300 = 15 + 300 = 315
300(1.04)^5 = 300 * 1.21665 = 365
In 5 years, the second account is higher.
3(12) + 300 = 336
300(1.04)^12 = 300 * 1.601 = 480

Mr. Johnson's lunch bill is $29.90, which includes a 15% típ
What is the price before tip, b, of Mr. Johnson's lunch?
Answers
Answer:
price before tip (b) = $26
Step-by-step explanation:
29.90 is INCLUDING tip, so the real bill, b, would be less.
Now, since 29.90 is including 15% tip, and we let the original bill be "b", we can say:
b INCREASED by 15% gives us 29.90
We need to come up with an equation and solve for b.
15% means 15/100 = 0.15
Now, we can write:
b + 15% of b = 29.90
or
b + 0.15b = 29.90
then
1.15b = 29.90
b = 29.90/1.15
b = 26
So, price before tip (b) = $26
Answer:
the answer is 26

Step-by-step explanation:
Given
- 13x - 8 ← factor out - 13 from each term
= - 13(x + [tex]\frac{8}{13}[/tex])
The question asked to factor out -13 from the expression -13x - 8. The steps include dividing each term by -13. Therefore, the expression factored out by -13 is -13(x + 8/13).
Explanation:In this mathematical problem, we are asked to factor out -13 from the expression -13x - 8. Factoring out in algebra means to divide each term in the expression by that common factor, which in this case is -13. So, we proceed as follows:
Divide -13x by -13 to get x.Divide -8 by -13 to get 8/13.Therefore, the expression -13x - 8 factored out by -13 is -13(x + 8/13).

From the given graph it is clear that the function is increasing on
[tex]-5<x<-1[/tex]
[tex]-1<x<1[/tex]
Decreasing function : In this function, the y-value decreases as the x-value increases.
From the given graph it is clear that the function is decreasing on

[tex]1<x<4[/tex]
To determine if a function is increasing, decreasing, or neither over intervals on a graph, analyze the direction of the graph. If the graph goes up, the function is increasing. If it goes down, the function is decreasing. If it remains flat, the function is neither increasing nor decreasing.
Explanation:The question asks to determine if the function is increasing, decreasing, or neither over each interval on the given graph. To do this, we need to analyze the direction of the graph. If the graph goes up as we move from left to right, the function is increasing. If the graph goes down, the function is decreasing. If the graph remains flat, the function is neither increasing nor decreasing. Drag the intervals to the appropriate box based on these observations.
A quadrilateral has vertices A(4,9), B(2,5), C(8,2), and D(10,6). Which statement about the quadrilateral is true?
Answers
Answer:
it is letter B
The given quadrilateral is not a parallelogram, is convex, and is not a square.
The question asks for the statement that is true about the given quadrilateral with vertices A(4,9), B(2,5), C(8,2), and D(10,6). To determine the truth of statements, we need to consider the properties of the given quadrilateral.
One statement that is true is that it is not a parallelogram. This can be proven by showing that opposite sides are not parallel, as the slopes are not equal.
Another statement that is true is that it is a convex quadrilateral. A convex quadrilateral is one where all interior angles are less than 180 degrees. To prove this, we can calculate the angles and show that they are all less than 180 degrees.
Lastly, a true statement is that it is not a square. A square is a special type of parallelogram with 4 equal sides and 4 right angles. We can determine this by calculating the lengths of the sides and showing that they are not all equal.

the area of a circular plot is 9856 metre square.calculate the cost of fencingthe plot at Rs.32.50 per metre.
Answers
Answer:
Rs 11440Step-by-step explanation:
Area of a circular plot is [tex]9856\text{ }m^{2}[/tex].
The area of a circle with radius [tex]r[/tex] is given by [tex]\pi r^{2}[/tex]
[tex]\pi r^{2}=9856\\r^{2}=9856\times\frac{7}{22}=3136\\r=56\text{ }m[/tex]
So, the radius of the circular plot is [tex]56\text{ }m[/tex].
Cost of fencing the plot is [tex]32.50\frac{Rs}{m}[/tex].
Total circumference of the circular plot is given by [tex]2\pi r[/tex]
Circumference = [tex]2\times\frac{22}{7}\times56=352\text{ }m[/tex]
Cost of fencing = [tex]352\text{ }m\times 32.50\frac{Rs}{m}=11440\text{ }Rs[/tex]
∴ Cost of fencing = Rs 11440

A piggy bank contains $5.60 in nickels and dimes. The number of nickels is 8 less than 3 times the dimes. How many nickels and dimes are there in the piggy bank?
The piggy bank has nickels and dimes.
Answers
Answer:
64 nickels and 24 dimes are there in the piggy bank.
Step-by-step explanation:
There are $5.60 in the piggy bank in nickels and dimes.
Let x number of nickels and y number of dimes are there.
Now, 1 nickel ≡ 0.05 dollars and 1 dime ≡ 0.1 dollars.
So, 0.05x + 0.1y = 5.6
⇒ 5x + 10y = 560
⇒ x + 2y = 112 ....... (1)
Again, from the condition given we can write that,
So, 3y - 8 = x ........ (2)
Now, solving (1) and (2) we get 3y - 8 + 2y = 112
⇒ 5y = 120
⇒ y = 24
And from equation (2) we get x = 3y - 8 = 64.
So, there are 64 nickels and 24 dimes in the piggy bank. (Answer)
Answer:
64 nickels and 24 dimes in the piggy bank.

What is the perimeter of a rectangle with a length of 9 - 2y and width of 7?
Answers
Answer:
The perimeter of the rectangle is 32 - 4y
Step-by-step explanation:
To find the perimeter, we will simply follow the steps below;
First write down the formula for finding the perimeter of a rectangle
The formula for finding perimeter in a rectangle is;
perimeter = 2l +2w
where l= length of the rectangle and w is equal to width of the rectangle
From the question given, length =9 - 2y and width =7
We can now proceed to insert the values into the formula;
perimeter = 2l +2w
=2(9-2y) + 2(7)
Then we will now simplify
perimeter =2(9-2y) + 2(7)
=18 - 4y + 14
= 18 + 14 - 4y
=32 - 4y
Therefore, the perimeter of the rectangle is 32 - 4y
The perimeter of the rectangle is 32-4y.
Step-by-step explanation:
Given information:
The length of the rectangle = 9-2y
The width of the rectangle = 7
Now
The perimeter (P) of the rectangle is :
[tex]P = 2( \text{Length} + \text{width})[/tex]
[tex]P= 2(9-2y+7)\\P=18-4y+14\\P=32-4y[/tex]
Hence, the perimeter of the rectangle is 32-4y.
