Marshall bought some pet supplies for $15. The sales tax was 6%. He wrote the expression 1.06(15) to find his total cost.
Which equivalent expression could he also use to find the total cost?
A (1+0.06)15
B 1+0.06(15)
C15+0.6(15)
D15 + 0.06
Answers
Answer:
A is correct
Step-by-step explanation:
Marshall bought some pet supplies for $15
The sales tax was 6%
Expression: 1.06(15)
Cost of pet = $15
Sale tax = 6% of 15
= 0.06×15
Total cost after sale tax = 15 + 0.06×15
Take out 15 common = (1+0.06)15
The given expression is equivalent to (1+0.06)15
1.06(15) = (1+0.06)15
Using (1+0.06)15 to find total cost.

What is y=-9/2x-11 in standard form?
Answers
So the equation you have listed follows the standard form of the slope formula
y=-9/2x(slope)-11(y-intersect)
Basically, you don't have to solve an equation that looks something like:
9/2x + y=-11 to put it into the standard form you have presented.
The standard form of the equation y = - 9/2x - 11 is 9x + 2y = - 22.
Given that,
The equation of a line is,
y = - 9/2x - 11
Now we can change the equation into standard form as,
y = - 9/2x - 11
Multiply both sides by 2;
2y = - 9x - 22
Add 9x on both sides,
2y + 9x = - 22
Arrange the equation,
9x + 2y = - 22
Therefore, the standard form is 9x + 2y = -22.

an appliance store sells a washer dryer combination for $1500 if the washer costs $200 more than the dryer find the cost of each appliance.
Answers
X+X+200=1500
Isolate the variable
2x=1300
X=650
Know that we know what X is, we know that X + 200 will equal the cost of the second appliance
650+850=1500
To find the cost of the washer and the dryer when the total cost is known along with the difference in their costs, we used a simple algebraic method of solving equations to determine that the dryer costs $650 and the washer costs $850.
Explanation:The question involves solving a system of linear equations to find the cost of two items whose total and difference in cost are known. To find the cost of each appliance, let's denote the cost of the dryer as x dollars. According to the problem, the washer costs $200 more than the dryer, so the washer's cost would be x + $200. The total cost of both appliances is $1500.
We can set up the following system of equations:
x + (x + 200) = 1500Solving the equations, we combine like terms:
2x + 200 = 15002x = 1300x = 650Now we know the dryer costs $650 and the washer costs $650 + $200 = $850.

Brian irons 2/9 of a shirt in 3 3/5 minutes. How long will it take him to iron one shirt? At this rate, how long will it take to iron 5 shirts?
Answers
15/5+3/5=18/5 (since 5 goes into 15 3 times), we can divide that by 2 to get 18/2/5=9/5. Multiplying that by 9, we get 9*9/5=81/5=the amount of minutes it would take to iron 1 shirt. Since 5 goes into 80 16 times, we can write 81/5 as 80/5+1/5=16+1/5. In addition, we need to find how long it would take to iron 5 shirts, and to do that we can multiply 1 shirt's time by 5, getting
81*5/5=405/5=81 minutes since 5 goes into 405 81 times.
Brian takes 16.2 minutes to iron one shirt and 81 minutes to iron five shirts at the rate of ironing 2/9 of a shirt in 3 3/5 minutes.
Brian irons 2/9 of a shirt in 3 3/5 minutes. To determine how long it takes to iron one full shirt, we can set up a proportion. Since 2/9 of a shirt takes 3 3/5 minutes, we can find the time for 1 shirt by multiplying 3 3/5 by 9/2.
First, we convert 3 3/5 to an improper fraction: (3 * 5) + 3 = 18/5. Now, multiply this by 9/2:
(18/5) * (9/2) = 81/5 = 16.2 minutes. Therefore, it takes 16.2 minutes to iron one shirt.
To find the time for 5 shirts, since the rate of ironing is constant, we multiply the time for one shirt by 5:
16.2 minutes * 5 = 81 minutes.
Brian will take 16.2 minutes per shirt, and 81 minutes for 5 shirts, at the given rate.

What is the recursive formula for the geometric sequence with this explicit formula?

for n=3 ; a₃ = 9.(-1/3)² =9/9 =1 or a₃ = a₂.(-1/3)²
so a₁ =9 and
a(n) = a(n-1)(-1/3) (ANSWER A)
Final answer:
To write a recursive formula for a geometric sequence, you need to know the first term and the common ratio. The recursive formula is expressed as each term being a multiple of its preceding term.
Explanation:
The question asks us to find a recursive formula for a geometric sequence when its explicit formula is already known. A recursive formula for a geometric sequence defines each term of the sequence as a multiple of the previous term, typically expressed as an = r × an-1, where r is the common ratio and an is the nth term. The first term, often denoted by a1, must be provided to start the sequence. To obtain a recursive formula, you need to know the first term and the common ratio. The explicit formula normally has the form an = a1 × rn-1. Using this explicit formula, you would need to solve for a1 and r to write the recursive formula.

The sum of two consecutive even integers is 218. What are the integers
Answers
They are consecutive even numbers.
If you combined them, you'd get 218.
The required two consecutive even integers that add up to 218 are 108 and 110.
What are integers?Integers are numbers that can be written without a fractional or decimal component, such as -3, -2, -1, 0, 1, 2, 3, and so on. They include the positive whole numbers (1, 2, 3, etc.), the negative whole numbers (-1, -2, -3, etc.), and zero.
To find the two consecutive even integers that add up to 218, we can use algebra.
Let's represent the first integer "x".
Since it is even, we know that it can be divided by 2 with no remainder.
Since it is also consecutive to the second integer, we can say that the second integer is "x + 2".
We can set up the equation:
x + (x + 2) = 218
Simplifying, we get:
2x + 2 = 218
2x = 216
x = 108
So the two consecutive even integers that add up to 218 are 108 and 110.

Critical points occur when both partial derivatives vanish; this happens when

The function has Hessian
[tex]\mathbf H(x,y)=\begin{bmatrix}\dfrac{\partial^2f}{\partial x^2}&\dfrac{\partial^2f}{\partial x\partial y}\\\\\dfrac{\partial^2f}{\partial y\partial x}&\dfrac{\partial^2f}{\partial y^2}\end{bmatrix}=\begin{bmatrix}2&1\\1&2\end{bmatrix}[/tex]
which at [tex](0,0)[/tex] has [tex]\det\mathbf H(0,0)=3>0[/tex]. And since [tex]\dfrac{\partial^2f}{\partial x^2}\bigg|_{x=0,y=0}=2>0[/tex], it follows that a local minimum occurs at [tex](0,0)[/tex] with a value of [tex]f(0,0)=0[/tex].
Meanwhile, we can parameterize the boundary by

Now,

A chicken soup recipe calls for 9 cups of chicken stock. How much is this in quarts? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.
Answers
There are 2.25 quarts in 9 cups of chicken stock.
Here's how we can convert cups to quarts:
Since "quarts" are commonly used as whole numbers or mixed numbers, we don't usually express them in decimals.
Conversion factor: Remember that there are 4 cups in 1 quart. This is the conversion factor we'll use.
Calculation: To find the equivalent amount in quarts, we can multiply the number of cups by the conversion factor:
9 cups * (1 quart / 4 cups) = 2.25 quarts
Therefore, 9 cups of chicken stock is equivalent to 2.25 quarts.
Final answer:
To convert 9 cups to quarts, we can use the conversion factor 4 cups = 1 quart. Therefore, 9 cups of chicken stock is equal to 2 1/4 quarts.
Explanation:
To convert cups to quarts, we can use the conversion factor 4 cups = 1 quart.
Given that the recipe calls for 9 cups of chicken stock, we need to determine how many quarts this is.
Using the conversion factor, we can set up the following proportion: 4 cups / 1 quart = 9 cups / x quarts.
Cross-multiplying, we get 4 * x = 1 * 9, which simplifies to x = 9/4 or 2 1/4 quarts.
Therefore, 9 cups of chicken stock is equal to 2 1/4 quarts.
