Find the total of each option to see which one is better.
Option 1:
$20 every week for 15 weeks = 15 x 20 = $300 total.
Option 2:
Week 1 you have 1 penny.
Week 2 you would have 1 +2 = 3 pennies.
Week 3 you would have 3 + 4 = 7 pennies.
From this we can see a pattern of 2^x - 1 where x is the number of weeks.
So in 15 weeks he would have 2^15 - 1 = 32767 pennies.
100 pennies equal $1
32767 / 100 = $327.67
The second option is better because he ends up with more money.

The high school leadership team is having a car wash. They charge $5.50 for large cars and $4.00 for small cars . They had a successful day, washed a total of 142 cars, and made $652.50. How many large cars and small cars did they wash?
Answer: 56 large cars and 86 small cars.
Step-by-step explanation:
Let's call:
[tex]l[/tex]: the number of large cars.
[tex]s[/tex]: the number of small cars.
Then, you can set up the following system of equations:
[tex]\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.[/tex]
You can use the Elimination Method:
- Multiply the first equation by -4.0
- Add both equations.
- Solve for l.
[tex]\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5[/tex]
[tex]l[/tex]≈[tex]56[/tex]
Substitute [tex]l=56[/tex] into one of the original equations and solve for s:
[tex]56+s=142\\s=142-56\\s=86[/tex]

Bill is saving for his son's college education. If the savings account earns 5% interest compounded monthly, and he wants to have $45,000 in 10 years, what must the principal be?
Answer:
$27,322.25
Step-by-step explanation:
Final answer:
To find the principal, you can use the formula for compound interest. The principal should be approximately $30,157.40.
Explanation:
To find the principal, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the future value of the investment (which in this case is $45,000)
P is the principal
r is the annual interest rate (which is 5% or 0.05)
n is the number of times interest is compounded per year (monthly compounding means n = 12)
t is the number of years
Using the given values, we have:
45000 = P(1 + 0.05/12)^(12*10)
Solving for P:
P = 45000 / (1 + 0.05/12)^(12*10)
P = 45000 / (1.00416667)^(120)
P ≈ 30157.40
Therefore, Bill must have a principal of approximately $30,157.40.
if i have 38 assignments and i do 15 of them what percentage do i have done?
Answer:
39.473%
Step-by-step explanation:
It is actually fairly simple to get the answer to this. What you can do to find any percentage, is to take the amount done, or whatever it is in the scenario, and divide it by the total. It is like turning it into a fraction, which you can do as well. Turn this into a fraction, and then convert it. 15/38, 15 divided by 38 = 39.473.
Hope this helped ^-^
To find the percentage you have done, divide the number you did by the total number you have to do:
15 / 38 = 0.3947
Multiply that by 100 to get the percentage:
0.3947 x 100 = 39.47% ( Round as needed).
If the length of the rectangle is 15 units long and the width is 11 units long, how long is the diagonal
Answer:
18.6 units
Step-by-step explanation:
A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. A diagonal can be drawn between opposite corners that splits the triangle into two equal right triangles. The distance of this diagonal is found using the Pythagorean Theorem a² + b² = c². In the rectangle a = 11 and b = 15. Substitute these values and simplify using a square root operation.
11² + 15² = c²
121 + 225 = c²
346 = c²
√346 = c
18.6= c
The local Walmart sold 67 televisions on Tuesday, 79 televisions on Wednesday, 195 televisions on Saturday, and 82 televisions on Sunday. How many televisions were sold in all over the weekend? The parking rates at the hospital's parking garage are 50 cents for the first hour and 25 cents for each additional hour. If Juan parks in the hospital's parking garage for 8 hours, how much will the total charge for parking be? Tom is on a diet. His diet plan allows him to have 1,000 calories for dinner. He's chosen a menu of enchiladas (537 calories), asparagus (96 calories), orange salad (78 calories), and cake (633 calories). If he eats this meal, will Tom be staying on his diet?
The total televisions sold over the weekend equals 177.
The cost of parking equals 50 cents for the first hour plus 25 cents for the additional 7 hours. Cost = .5 +7 x .25 = $2.25
In order to see if Tom is staying on his diet you need to add the total calories of the food that he is planning on eating for dinner. The total is 1,344 calories, so if he ate all of it he would not be staying on his diet.
The perimeter of a triangle is given by the formula P = a + b + c. Solved for b, this formula becomes b =
Answer: B) P-a-c.
Step-by-step explanation:
The value of b is P - a - c.
Given,
The perimeter of a triangle is given by the formula P = a + b + c.
We need to solve for b.
What is the perimeter of a triangle?The total length of all three sides of a triangle is called the perimeter of the triangle.
It is given by:
P = a + b + c
Where a,b, and c are the sides of the triangle.
We have,
P = a + b + c
Subtracting a on both sides
P - a = a + b + c - a
P - a = b + c
Subtracting c on both sides
P - a - c = b + c - c
P - a - c = b
We get,
b = P - a - c
Thus the value of b is P - a - c.

Enter the system represented on the graph below. Find and explain the meaning of the point of intersection of the lines.
Answer:
y = -2x+4
y = (3/2)x -3
The point of intersection is (2, 0), or x=2 and y=0.
Step-by-step explanation:
The downward-sloping line drops 2 grid squares for each 1 it goes to the right, so its slope is -2. It intersects the y-axis at +4. In slope-intercept form, its equation is ...
y = slope · x + (y-intercept)
y = -2x + 4
Similarly, the upward-sloping line rises 3 grid squares for each 2 it goes to the right, so its slope is 3/2. It intersects the y-axis at -3. Its equation is ...
y = (3/2)x -3
The two lines intersect at the point where x=2 and y=0, so the coordinates are (2, 0). These are the values of x and y that satisfy both equations, so are the solution to the system.

This graph of a function is a translation of y=4/x. What is an equation for the function?
[tex]y = \frac{4}{x + 6} + 2 \\ [/tex]
found by:
as value of x approaches -6 from left, value of y appoaches negative infinity
as value of x approaches -6 from the right, value of y approaches infinity
(undefined solution)
therefore, the value of x = 0 is translated to x = - 6
if x = -6,
(x + 6) = 0
(x + 6) is the value of x in the equation
[tex]y = \frac{4}{x + 6} + c[/tex]
as x increases, the value of 4/x approaches 0
in the graph, it approaches 2 instead
meaning 2 units is added to the value of y,
therefore c = 2.

Please help! The graph of function g(x) is a transformation of the graph of function f(x) = x^2.
g(x) = _________
A.) 2x^2+3
B.) -2x^2-3
C.) -1/2x^2-3
D.) 1/2x^2-3
Answer:
B.) -2x^2-3
Step-by-step explanation:
You only need to look at the values of the offered answers for x=1 in order to determine the correct one.
A.) for x = 1, 2·1+3 = 5
B.) for x = 1, -2·1-3 = -5 . . . . matches the graph
C.) for x = 1, -1/2·1-3 = -3 1/2
D.) for x = 1, 1/2·1-3 = -2 1/2
___
Comparing the values at x=1 to the values at x=0, you find that f(1)-f(0) = 1, while g(1)-g(0) = -2. This tells you the multiplier is -2, so matches choice B.
The fact that the vertex of g(x) is 3 units below that of f(x) tells you that -3 has been added to the product -2x^2.
_____
Comment on vertical scale factor
Since 1^2 = 1, it is often convenient to look at a point that is 1 unit away from the vertex of the function. The function value relative to the vertex value at that point will tell you the vertical scale factor.
For example, we know that the coefficient of x^2 is 1 in f(x), and we see on the graph that f(1) is 1 unit above the vertex at (0, 0). The value of g(1) is -5, which is 2 units below the vertex of g(x) at (0, -3). So, the vertical scale factor is -5-(-3) = -2.
Jacob's daily tips this work week were $99, $78, $58, $91, $90, and $68. Is Jacob correct in thinking that the median best represents how much money he makes in daily tips?
Answer:
no
Step-by-step explanation:
median only shows the amount in the very middle. to represent how much money he makes in daily tips, he needs to find the mean (the average).
Answer:
Little close
Step-by-step explanation:
In statistics, when we have a list of entries to be analyzed we have few figures for observation. These are
Mean , median and mode.
Mean gives the average of all the entries. By average means.
Median gives you the middle most entry.
And mode gives the entry repeated the most.
As by definition we see that , median will give us approximation regarding daily data, hence jacob must consider the median to best represent the money he makes on daily basis.

The gravitational force on the earth is six times greater than on the moon. This means objects weigh six times as much on earth as they do on the moon. Write an algebraic expression for the weight of an object on earth if its weight on the moon is m.
Answer:
y=6x
Step-by-step explanation:
let y be the weight of an object on the earth
let x be the weight of the same object on the moon
Since the weight of an object on earth is 6 times greater than the same thing on the moon, You must multiply the weight of something on the moon by six.
Hope this helped!
Final answer:
The algebraic expression for the weight of an object on Earth given its weight on the Moon, denoted as 'm', is 'W = 6m', where 'W' represents its weight on Earth.
Explanation:
The question is asking us to find an algebraic expression for the weight of an object on Earth given its weight on the Moon.
We know that the gravitational force on Earth is six times greater than on the Moon, which means objects weigh six times more on Earth than on the Moon.
If the weight of an object on the Moon is given as m, then the weight of the same object on Earth, W, would be W = 6m.
