The cashier gave Mary an amount of $49.64 in change.
Mary's mom gave her $100.00 to go shopping.
She spent $22.65 on a shirt and $33.31 on a skirt. She had a coupon for 10% off. Mary's total expenditure can be calculated by adding the cost of the skirt and the shirt:
Shirt + Skirt = $22.65 + $33.31 = $55.96
The cost of the items with the discount is the Total cost after discount
= $55.96 − 10% of $55.96 = $55.96 − $5.596 = $50.36
Since Mary was given $100.00 by her mother, she has to subtract the total amount she spent from the total she was given.
This will give us her total change:
$100.00 − $50.36 = $49.64

Complete the table. Enter your answers in the boxes.

Independent
There are 44 Democratic senators and no Independent senators based on ratio.
Since the ratio of Republicans to Democrats is 5:4, we can represent the number of Republican senators as 5x and the number of Democratic senators as 4x, where x is a positive integer. The total number of senators is given as 100, so we have:
5x + 4x + Independent = 100
Simplifying:
9x + Independent = 100
To find the values of x and Independent, we need to solve for these variables. We can start by subtracting Independent from both sides of the equation:
9x = 100 - Independent
Now, we need to find a value of x that makes the right-hand side of the equation divisible by 9. Since the sum of the digits of 100 is 1 + 0 + 0 = 1, which is not divisible by 9, we need to find a value of Independent that makes the sum of the digits of 100 - Independent divisible by 9. The only value that works is Independent = 1, which gives us:
9x = 99
x = 11
Now we can substitute this value of x back into the equation to find the number of Republican and Democratic senators:
Republican = 5x = 5(11) = 55
Democrat = 4x = 4(11) = 44

What is the positive solution to this equation? 4x2 + 12x = 135 Record your answer and fill in the bubbles on your answer document.
x = 3 is the answer that gives the equation 4x2 + 12x = 135 a positive solution
To solve the equation 4x² + 12x = 135, we can start by rearranging it to the standard quadratic form ax² + bx + c = 0, where a, b, and c are constants. We get:
4x² + 12x - 135 = 0
Next, we can divide both sides of the equation by 4 to simplify it:
x² + 3x - 33.75 = 0
To solve for x, we can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
In this case, a = 1, b = 3, and c = -33.75. Substituting these values into the formula, we get:
x = (-3 ± √(3² - 4(1)(-33.75))) / 2(1)
Simplifying the expression inside the square root, we get:
x = (-3 ± √(9 + 135)) / 2
x = (-3 ± √144) / 2
x = (-3 ± 12) / 2
So the two solutions are:
x = -7.5 or x = 3. From the problem statement, we are looking for a positive solution, so we can discard the negative solution x = -7.5.
Therefore, the positive solution to the equation 4x² + 12x = 135 is x = 3.

20-29 86
30-39 1
40-49 1
50-59 68
60-69 15

What is the probability that a randomly selected unicyclist from Corvallis, OR. Is not between 30 and 39?
The probability that an arbitrarily chosen Corvallis unicyclist is not between the ages of 30 and 39 is roughly 0.995, or 99.5%.
To find the probability that a randomly selected unicyclist from Corvallis is not between 30 and 39, we need to first determine the total number of unicyclists in Corvallis. We can find this by summing up the frequencies for all age groups:
Total number of unicyclists = 16 + 86 + 1 + 1 + 68 + 15 + 14 = 201
Next, we need to determine the frequency of unicyclists who are not between 30 and 39. We can do this by adding up the frequencies for all age groups that are not between 30 and 39:
Frequency of unicyclists not between 30 and 39 = 16 + 86 + 1 + 68 + 15 + 14 = 200
Finally, we can calculate the probability of selecting a unicyclist who is not between 30 and 39 by dividing the frequency of unicyclists not between 30 and 39 by the total number of unicyclists:
P(not between 30 and 39) = Frequency of unicyclists not between 30 and 39 / Total number of unicyclists
P(not between 30 and 39) = 200 / 201
P(not between 30 and 39) ≈ 0.995
Therefore, the probability that a randomly selected unicyclist from Corvallis is not between 30 and 39 is approximately 0.995 or 99.5%.

It was Mrs. Johnson's birthday, and she made her favorite homemade cookies to share with the class. "I hope you all enjoy my homemade cereal crunch cookies. I used a mixture of different cereals to make this. Unique!" says Mrs. Johnson as she saw Joshua raise his hand. "But don't worry! They are all nut free." The class LOVED them. In no time at all the class ate five-sixths of the cookies. "Mrs. Johnson." said Hannah, "you need to do OUR tradition. While we sing happy birthday, you need to eat as many cookies as you can. As the class began to sign, that is just what Mrs. Johnson did. And she was good at it! She ate three-fourths of the cookies that were left. In case you are curious, that was equal to 3 cookies! How many cookies did Mrs. Johnson bring to class that day?
Answer:
Let's work backwards to figure out how many cookies were left after Mrs. Johnson ate 3 cookies:
Before Mrs. Johnson ate the cookies, the class had eaten 5/6 of the cookies, which means that 1/6 of the cookies were left.
Let's call the number of cookies in 1/6 of the batch "x". So the total number of cookies is 6x.
After the class ate 5/6 of the cookies, there were 1/6 of the cookies left, which is x.
Then Mrs. Johnson ate 3/4 of the cookies that were left, which means she ate 3/4*x cookies.
We know that Mrs. Johnson ate 3 cookies, so we can set up the equation: 3 = 3/4*x
Solving for x:
3 = 3/4x
34/3 = x
4 = x
So there were 4 cookies in 1/6 of the batch, which means there were 6 times as many, or 6*4 = 24 cookies in the whole batch.
Therefore, Mrs. Johnson brought 24 cookies to class that day.
Answer: 24 cookies.
Step-by-step explanation:
the answer to the questions is as below
Let's start by using variables to represent the number of cookies that Mrs. Johnson brought to class. Let's say she brought "x" cookies.
We know that the class ate five-sixths of the cookies, which means that there were only one-sixth of the cookies left. This can be represented as:(1/6)x cookies left
We also know that Mrs. Johnson ate three-fourths of the cookies that were left, which is equal to 3 cookies. We can set up an equation to represent this:
(3/4)(1/6)x = 3
Simplifying this equation, we get:
(1/24)x = 1
x = 24
Therefore, Mrs. Johnson brought 24 cookies to class that day.
A water balloon is dropped from the second floor of a five-story building. The height in feet is modeled by f(x) = -8x^2 + 80x where x is the number of elapsed seconds. How long will the water balloon be in the air?
When A water balloon is dropped from the second floor of a five-story building, The water balloon will be in the air for 10 seconds.
To find the time the water balloon will be in the air, we need to find when the height function f(x) equals zero since this is the point at which the balloon hits the ground.
Setting f(x) = 0 and solving for x, we get:
-8x^2 + 80x = 0
=> x(-8x + 80) = 0
=> x = 0 or x = 10
Since x = 0 is the initial time when the balloon is dropped, we can discard that solution. Therefore, the water balloon will be in the air for 10 seconds.

A golf retailer purchases its clubs from a wholesaler at $41 per club. It sells the same clubs to golfers at $71 per club. What is the markup on each club, as a percentage of the wholesale price?
The markup is 73.17 percentage , calculated by subtracting the wholesale price ($41) from the retail price ($71) and then dividing the difference by the wholesale price ($41).
The markup is the difference between the wholesale price and the retail price, divided by the wholesale price. To calculate the markup on each club, subtract the wholesale price from the retail price and then divide the difference by the wholesale price. In this example, the wholesale price is $41 and the retail price is $71, so the difference is $30. Dividing $30 by $41 gives a result of 0.7317, which is the markup expressed as a decimal. To express the markup as a percentage, multiply the result by 100, giving a final answer of 73.17%. This means that the retailer is marking up their clubs by 73.17% of the wholesale price.

The volume of Joey's toy box is 24 cubic inches.
If the base of the toy box is filled with 8 1-inch cubes, then the volume of the base is:
Volume of base = 8 cubes x [tex](1 inch/cube)^3[/tex] = 8 cubic inches
If the toy box has two more layers on top of the base, then it has a total of three layers. Let's call the height of each layer "h". Then the total height of the toy box is:
Total height = 3h
The volume of each layer is the same as the volume of the base, which is 8 cubic inches. Therefore, the volume of the entire toy box is:
Volume of toy box = volume of base + volume of 2 layers
Volume of toy box = 8 cubic inches + 2(8 cubic inches)
Volume of toy box = 8 cubic inches + 16 cubic inches

Setting the derivative equal tο zerο, we get:
6x - 3x^2 = 0
3x(2 - x) = 0
Sο the critical pοints are at x = 0 and x = 2.
Tο determine whether these critical pοints cοrrespοnd tο a lοcal maximum οr minimum, we can use the secοnd derivative test. Taking the secοnd derivative οf the functiοn, we get:
[tex]d^2y/dx^2 = 6 - 6x[/tex]
At[tex]x = 0, d^2y/dx^2 = 6[/tex], which is pοsitive, sο this critical pοint cοrrespοnds tο a lοcal minimum. At[tex]x = 2, d^2y/dx^2 = -6[/tex], which is negative, sο this critical pοint cοrrespοnds tο a lοcal maximum.
Tο find the smallest and largest values οf the functiοn, we need tο evaluate the functiοn at these critical pοints and at the endpοints οf the interval οf interest. The interval οf interest is nοt specified, sο we will assume that we want tο find the smallest and largest values οver the entire real line.
y(-∞) = -∞ (as x apprοaches negative infinity, y apprοaches negative infinity)
y(0) = 0
y(2) = 8
y(∞) = -∞ (as x apprοaches infinity, y apprοaches negative infinity)
Therefοre, the smallest value οf the functiοn is negative infinity, and the largest value is 8.

What is sine rule?The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.
w/sinW = v/sinV
using the sum of angle in a triangle
V + W + U = 180°
V + 79 + 82 = 180°
V = 180-(79+82)11
V = 180 - 161
V = 19°
1690/sin 79 = v/ sin19
sin79 v = 690 sin 19
0.982 v = 690 × 0.33
0.982v = 227.7
v = 227.7/0.982
