At a pizza shop, 6 slices of pizza and 2 drinks cost the same as 5 slices of pizza and 5 drinks. Each slice of pizza costs $4.50. Find the cost in dollars of each drink.
Answer:
Each drink costs $1.50
Step-by-step explanation:
Let d = the cost of a drink
6(4.50) + 2d = 5(4.5) + 5d Distribute the 6 and 5
27 + 2d = 22.50 + 5d Subtract 2d from both sides
27 + 2d - 2d = 22.50 + 5d - 2d
27 = 22.50 + 3d Subtract 22.50 from both sides
4.5 = 3d Divide both sides by 3
1.50 = d
What is the lower bound for the perimeter of the rectangle when the length is 87. 3cm and the width is 51. 8cm
The lower bound for the perimeter of the rectangle when the length is 87. 3cm and the width is 51. 8cm is 278.24 cm.
Lower bound is the minimum valued number that have been before it was rounded to the nearest. As per the query, we need to find the perimeter of the rectangle whose length is 87.3 cm while its width is 51.8cm. The perimeter of a rectangle is given by the formula:
=2 (l + b)
=2 (87.3 + 51.8)
=2 (139.1)
=278.2 cm
Therefore, the perimeter of the rectangle, when the length is 87. 3cm and the width is 51. 8cm is, 278.2 cm.
We need to assume the lower bound value for this value. We can assume that 278.2 may have been 278.24cm before it was rounded to the nearest value, i.e., 278.2cm. Thus, the lower bound for the perimeter of the rectangle when the length is 87. 3cm and the width is 51. 8cm is 278.24 cm.

describe a linear program whose solution describes the largest axis-aligned square that lies entirely inside p.
To describe a linear program for finding the largest axis-aligned square that lies entirely inside a polygon (p), we can define the decision variables, objective function, and constraints as follows:
Decision Variables:
Let x be the side length of the square.
Objective Function:
Maximize x. The objective is to find the largest possible side length for the square.
Constraints:
Square Within Polygon Constraint:
For each vertex (xᵢ, yᵢ) of the polygon p, we can define the following set of inequalities:
xᵢ ≤ x, for all vertices of the polygon.
These inequalities ensure that the square lies entirely within the polygon.
Square Symmetry Constraint:
To ensure that the square is axis-aligned, we can impose symmetry constraints. For example, if the coordinates of the center of the square are (c_x, c_y), then we can add the following constraints:
c_x ± (x/2) = constant, for fixed values of c_x.
c_y ± (x/2) = constant, for fixed values of c_y.
These constraints ensure that the sides of the square are parallel to the x and y axes.
Non-Negative Constraint:
x ≥ 0, to ensure a non-negative side length for the square.
By formulating and solving this linear program, we can find the optimal value for x, which represents the largest axis-aligned square that lies entirely within the given polygon p.

After answering the given query, we can state that So, -6 is the figure equation we're searching for.
What is equation?Using the equals sign (=) to indicate equivalence, a math equation links two statements. Algebraic equations prove the equality of two mathematical formulas through a mathematical assertion. The equal symbol, for example, puts a space between the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. You can use a mathematical formula to understand the connection between the two lines that are printed on opposite sides of a letter. Most of the time, the emblem and the particular program match. e.g., 2x - 4 = 2 is an example.
"x + 5" can be used to represent "five more than a particular number."
It is possible to express "four less than half that number" as "0.5x - 4".
Thus, the solution is:
x + 5 = 0.5x - 4
We can now determine x:
x + 5 = 0.5x - 4
Take 0.5x away from both sides:
0.5x + x + 5 = -4
combining similar words
1.5x + 5 = -4
Take 5 away from both ends.
1.5x = -9

Determine the fraction that is equivalent to the repeating decimal 0.35. (Be sure to enter the fraction in reduced form.) Provide your answer below:
The fraction that is equivalent to the repeating decimal 0.35 is 7/20.
To determine the fraction that is equivalent to the repeating decimal 0.35, we can follow the steps below:
Step 1: Let x be equal to the repeating decimal 0.35.
Step 2: Multiply both sides of the equation in Step 1 by 100 to eliminate the decimal point:
100x = 35.35
Step 3: Subtract the equation in Step 1 from the equation in Step 2 to eliminate the repeating decimal:
100x - x = 35.35 - 0.35
99x = 35
Step 4: Simplify the equation in Step 3 by dividing both sides by 99:
x = 35/99
Step 5: Simplify the fraction 35/99 to reduced form by dividing both the numerator and denominator by their greatest common factor, which is 5:
35/99 = (7 x 5)/(11 x 9 x 5) = 7/20
Therefore, the fraction that is equivalent to the repeating decimal 0.35 is 7/20.
To understand how we arrived at the fraction 7/20 as the equivalent of the repeating decimal 0.35, we need to have a basic understanding of decimals and fractions.
Decimals are a way of expressing parts of a whole in base 10. In a decimal number, the digits to the right of the decimal point represent fractions of 10, 100, 1000, and so on. For example, the decimal 0.35 represents 3/10 + 5/100, which can be simplified to 35/100.
On the other hand, fractions are a way of expressing parts of a whole in terms of a numerator and a denominator. The numerator represents the number of equal parts being considered, and the denominator represents the total number of equal parts that make up the whole. For example, the fraction 7/20 represents 7 parts out of 20 equal parts, or 7/20 of the whole.
Sometimes, a decimal number can be expressed as a fraction with integers as the numerator and denominator. These types of fractions are called rational numbers, and they can be expressed as terminating decimals or repeating decimals.
Terminating decimals are decimals that end, such as 0.5, 0.75, or 0.125. These decimals can be expressed as fractions with integers as the numerator and denominator by counting the number of decimal places and setting the denominator to a power of 10 that corresponds to that number. For example, 0.5 can be expressed as 5/10, which simplifies to 1/2.
Repeating decimals are decimals that have a pattern of one or more digits that repeat infinitely. For example, the decimal 0.333... has a repeating pattern of 3, and the decimal 0.142857142857... has a repeating pattern of 142857. These decimals can also be expressed as fractions with integers as the numerator and denominator.
To convert a repeating decimal to a fraction
We start by letting x be the repeating decimal, and we multiply both sides of the equation by 10, 100, 1000, or some other power of 10 to eliminate the decimal point. We then subtract the original equation from the new equation to eliminate the repeating decimal, and we simplify the resulting equation by dividing both sides by a common factor. The resulting fraction can then be simplified to reduced form by dividing both the numerator and denominator by their greatest common factor.
In the case of the repeating decimal 0.35, we followed these steps and arrived at the fraction 7/20 as the equivalent. This means that 0.35 and 7/20 represent the same value or amount. To verify this, we can convert 7/20 to a decimal by dividing 7 by 20, which gives 0.35.
Therefore, 0.35 and 7/20 are equivalent forms of the same value or amount.

Therefore, the compound interest of the annuity due of BD 400 paid each 4 months for 6.2 years at a nominal rate of 3% per annum is BD 40,652.17.
Compound interest of an annuity due can be calculated using the formula:A = R * [(1 + i)ⁿ - 1] / i * (1 + i)
whereA = future value of the annuity dueR = regular paymenti = interest raten = number of payments First, we need to calculate the effective rate of interest per period since the nominal rate is given per annum. The effective rate of interest per period is calculated as
:(1 + i/n)^n - 1 = 3/1003/100 = (1 + i/4)^4 - 1
(1 + i/4)^4 = 1.0075i/4 = (1.0075)^(1/4) - 1i = 0.0303So,
the effective rate of interest per 4 months is 3.03%.Next, we can substitute the given values in the formula:
A = BD 400 * [(1 + 0.0303)^(6.2 * 3) - 1] / 0.0303 * (1 + 0.0303)A = BD 400 * [4.227 - 1] / 0.0303 * 1.0303A = BD 400 * 101.63A = BD 40,652.17

How do you calculate decay from half-life?
Using the formula T1/2 = 0.693/λ, we may determine decay from half-life.
What is half-life?The half-life is the amount of time needed for half of the initial population of radioactive atoms to decay.
T1/2 = 0.693/λ describes the relationship between the half-life, T1/2, and the decay constant.
A percentage is used to represent the degradation rate.
Simply decreasing the percent and dividing it by 100 yields the decimal equivalent.
The decay factor b = 1-r can therefore be calculated.
For instance, the exponential function's decay rate is 0.25, and the decay factor b = 1- 0.25 = 0.75 if the rate of decay is 25%.
Nearly all decay processes that are exponential, or nearly exponential, are referred to by the phrase "half-life".
Therefore, using the formula T1/2 = 0.693/λ, we may determine decay from half-life.

the price of the four new tires changes from $638 to $523 find the percent of increase or decrease
A.18% decrease
B.18% increase
C. 22% decrease
D 22% increase
Step-by-step explanation:
To find the percent change in price of the four new tires, we can use the formula:
percent change = (new value - old value) / old value * 100%
Here, the old value is $638 and the new value is $523.
percent change = ($523 - $638) / $638 * 100%
percent change = -$115 / $638 * 100%
percent change = -0.18 * 100%
percent change = -18%
The result is a decrease of 18%, so the answer is A. 18% decrease.
Okay, let's solve this step-by-step:
Original price of 4 tires: $638
New price of 4 tires: $523
To calculate the percent change, we use the formula:
Percent Change = (New Price - Original Price) / Original Price
So in this case:
Percent Change = ($523 - $638) / $638 = -$115 / $638 = -0.18 = 18%
Since the new price is less than the original price, this is a decrease.
Therefore, the answer is A: 18% decrease
So the answer is A: 18% decrease
