My restaurant budget should not go over $100. If I bought main dish for $50 and $12 for each pizza, how many pizza's can I buy?
inequality :
50 + 12x ≤ 100
How many pizza's can I buy?
Answer:
x = 25
Step-by-step explanation:
50 + 12x <_ 100
12x <_ 100 - 50
12x <_ 50
x <_ 50 / 12
x <_ 25
You can buy about 4 pizzas.
I didn't use the way that I probably should have but you can subtract 50 from 100 and then divide the 50 by 12 and you will get 4.1666667.

Hilary walked 18 yards from her house to the library. Then she walked 288 feet to the post office. What is the total distance in yards Hilary walked? Use the conversion chart below to solve.
Answer:
37 yards
Step-by-step explanation:
Given data
Distance from house to the library= 18 yards
Distance from the library to the post office= 288 feet
Total distance in yards, first let us have all units to yards
288ft to yard= 96 yards
Hence the total distance in yards is
=18+19
=37 yards
Fitting a straight line to a set of data yields the following prediction line.
Y_i = 14 - 0.2X_i I
nterpret the meaning of the Y-intercept, b_0.
The Y-intercept (b_0 = 14) represents the predicted value of Y when X is zero.
In the given prediction line equation, Y_i = 14 - 0.2X_i, the Y-intercept is represented by the term '14', which is the coefficient of the constant term.
The Y-intercept, denoted as b_0, represents the predicted value of the dependent variable (Y) when the independent variable (X) is equal to zero. In this case, when X is zero, the equation becomes:
Y_i = 14 - 0.2(0) = 14
Therefore, the Y-intercept (b_0 = 14) represents the predicted value of Y when X is zero. It is the point where the prediction line intersects the Y-axis. In practical terms, it means that when the independent variable has no effect or has a value of zero, the predicted value of the dependent variable is 14.

(a) y = cx⁵ and 5x² + y² = k are do not satisfy the conditions for orthogonality.
(b) x² + y² = 2cy and x² + y² = 2kx potentially represent families of orthogonal functions .
(c) x² = y² + c and y = kx potentially represent families of orthogonal functions .
a. y = cx⁵ and 5x² + y² = k: Definitely incorrect. The equation 5x² + y² = k represents an ellipse, whereas the equation y = cx⁵ represents a polynomial function. These two functions do not satisfy the conditions for orthogonality.
b. x² + y² = 2cy and x² + y² = 2kx: Potentially correct. Both equations represent circles in the xy-plane. However, for them to be orthogonal functions, the centers of the circles need to coincide at the origin (0, 0). If the centers are at the origin, then these equations can be potentially correct as orthogonal functions.
c. x² = y² + c and y = kx: Potentially correct. The equation x² = y² + c represents a hyperbola, and the equation y = kx represents a straight line passing through the origin. If the hyperbola is centered at the origin and the line passes through the origin, then these equations can be potentially correct as orthogonal functions.

3. The ratio of the side lengths of a pentagon is 1:3:4:6:9, and the perimeter is 115 yds. What is the measure of the 3rd longest side?
Answer:
20 yards
Step-by-step explanation:
By the given ratio, the side measurements are 1x, 3x, 4x, 6x, and 9x
We are given the perimeter of this shape is 115. Therefore, 1x+3x+4x+6x+9x=115.
We can solve that for x, so we can find each side measurements' numerical value.
(1+3+4+6+9)x=115
(23)x=115
x=115/23
x=5
So the side measurements are:
1x=1(5)=5
3x=3(5)=15
4x=4(5)=20
6x=6(5)=30
9x=9(5)=45
The third longest sife is 20 yards.

EH is a diameter is D. The measure of EF is (10x + 8) and the measure of GH is (11x). What's the value of X
Answer:
x = 5°
EF = 58°
GH = 55°
Step-by-step explanation:
From The diagram :
Recall ; Angle on a straight line = 180°
This means :
EF + FG + GH = 180
EF = (10x + 8)°
GH = (11x)°
FG = 67°
HENCE;
10x + 8 + 11x + 67 = 180
21x + 75° = 180°
21x = 180 - 75
21x = 105
x = 105 / 21
x = 5
EF = 10x + 8 = 50 + 8 = 58°
GH = 11x = 11 * 5 = 55°

To find the inverse of the one-to-one function defined by the given set of points {(2, 11), (3, -4), (4, -1), (5, -14), (6, 1)}, we need to swap the x-values with the y-values to obtain the reversed pairs of points.
The inverse function is {(11, 2), (-4, 3), (-1, 4), (-14, 5), (1, 6)}.
The domain of the inverse function is the set of all x-values from the original function, which in this case is {11, -4, -1, -14, 1}.
The range of the inverse function is the set of all y-values from the original function, which in this case is {2, 3, 4, 5, 6}.

State a decomposition theorem for finite generated modules over the PID a Z(p) = {{ = : a : a,b € Z and płb}.
Decomposition theorem for finite generated modules over the PID $\mathbb{Z}(p) = \{a = (a, b) \in \mathbb{Z} \times \mathbb{Z} | p | ab\}.$
The decomposition theorem states that any finite generated module over a principal ideal domain can be written as a direct sum of finitely many cyclic submodules. Additionally, these cyclic submodules are uniquely determined up to isomorphism, which means that the module has a unique decomposition up to isomorphism. In the case of $\mathbb{Z}(p)$, we can write it as a direct sum of cyclic submodules generated by elements of the form $p^k$ for $k \in \mathbb{Z}$. This decomposition is unique up to isomorphism. The primary decomposition theorem enables us to represent a vector space as a direct sum of invariant subspaces by using the smallest polynomial of a matrix. It is essential to comprehending and interpreting the data the minimal polynomial provides.

The information for this question was obtained from the study linked here.) When a person consumes a drug, the drug is absorbed into the bloodstream over a period of time. In this question, we investigate the peak concentration of a drug in the blood stream. Caffeine is a drug that is absorbed and eliminated according to first-order kinetics. Suppose that a person's rate of caffeine absorption is 8 and that the person's rate of elimination is 7. Then after a dose D of caffeine, the concentration c of caffeine in the person's blood as of time t is given by
c(t)=(D/(1-(7/8))((e^-7t)-(e^-8))
Find the exact time at which the maximum concentration occurs.
t= ___
The exact time at which the maximum concentration occurs is given by: [tex]t = (ln(7/8) + 8) / 7[/tex]
To find the exact time at which the maximum concentration occurs, we need to determine the value of t that maximizes the concentration function c(t).
Given the concentration function:
[tex]c(t) = (D / (1 - (7/8))) * ((e^{-7t}) - (e^{-8}))[/tex]
To find the maximum concentration, we can differentiate c(t) with respect to t and set the derivative equal to zero, then solve for t.
Differentiating c(t) with respect to t:
[tex]c'(t) = (D / (1 - (7/8))) * ((-7e^{-7t}) - (-8e^{-8}))\\ = (D / (1 - (7/8))) * (-7e^{-7t} + 8e^{-8})[/tex]
Setting c'(t) equal to zero:
[tex](D / (1 - (7/8))) * (-7e^{-7t} + 8e^{-8}) = 0[/tex]
Since D is a positive constant, we can ignore it in the equation. So we have:
[tex]-7e^{-7t} + 8e^{-8} = 0[/tex]
[tex]-7 + 8e^{-8+7t} = 0\\8e^{-8+7t} = 7\\e^{-8+7t} = 7/8\\-8 + 7t = ln(7/8)\\7t = ln(7/8) + 8\\t = (ln(7/8) + 8) / 7[/tex]
Therefore, the exact time at which the maximum concentration occurs is given by: t = (ln(7/8) + 8) / 7

(a) S = {(1, 3), (3, 2), (-2, 6)}
O linearly independent set
S is linearly independent because no vector in S can be expressed as a linear combination of the others, without considering the coefficients all equal to zero.
(b) S = {(1, -5, 4), (4, -20, 16)}
O linearly dependent
We can see that 4 × (1, −5, 4) = (4, −20, 16).
Thus, S is linearly dependent because there are non-zero scalars a,b that satisfies a(1, −5, 4) + b(4, −20, 16) = 0.
(c) S = {(0, 0), (1, 0)}
O linearly dependent
vector (0, 0) is a linear combination of (1, 0) because 0(1, 0) = (0, 0).
Thus, S is linearly dependent because there are non-zero scalars a,b that satisfies a(0, 0) + b(1, 0) = 0.

(a) To calculate the final frequencies in the contingency table, we need to sum up the frequencies for each combination of variables. The final frequencies are as follows:
Size of restaurant: Seats 100 or fewer
- Excellent: 182
- Fair: 200
- Poor: 161
Size of restaurant: Seats over 100
- Excellent: 186
- Fair: 316
- Poor: 155
(b) To find the expected frequency for each cell in the contingency table, we can use the formula:
Expected Frequency = (row total * column total) / grand total
The expected frequencies for each cell in the contingency table are as follows:
Size of restaurant: Seats 100 or fewer
- Excellent: (513 * 368) / 1200 ≈ 157.60
- Fair: (513 * 516) / 1200 ≈ 220.95
- Poor: (513 * 356) / 1200 ≈ 151.77
Size of restaurant: Seats over 100
- Excellent: (557 * 368) / 1200 ≈ 171.53
- Fair: (557 * 516) / 1200 ≈ 237.85
- Poor: (557 * 356) / 1200 ≈ 164.62
(a) The final frequencies in the contingency table are obtained by summing up the frequencies for each combination of the variables "Size of restaurant" and "Rating." This gives us the observed frequencies for each category.
(b) The expected frequency for each cell is calculated using the formula mentioned above. It considers the row total, column total, and grand total of the contingency table.
The expected frequencies represent the frequencies we would expect to see in each cell if the variables were independent of each other. These values are used to assess the association between the two variables.

Based on the given information, Allie's misunderstanding is likely related to the concept of regrouping or borrowing when performing subtraction.
Allie may not have correctly subtracted the tens digit from the hundreds digit, resulting in an incorrect answer.
If Allie's misunderstanding is not corrected, her answer for 304 - 9 would also be incorrect.
Let's calculate it correctly:
When subtracting 9 from 304, we start with the one digit: 4 - 9.
However, since 4 is smaller than 9, we need to borrow from the tens digit. Therefore, we regroup 1 ten as 10 ones, making the tens digit 3 - 1 = 2, and the one's digit becomes 14 - 9 = 5.

Natalie are.
Answer:
N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28
Step-by-step explanation:
Using variables N=natalies age and F=Freds age
N+F=42 ----> N=42-F (take this and plug it into the other equation)
F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]
-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]
So N+28=42 or N=14.

Answer: 358 + 360n where n is an integer
Reason:
Coterminal angles point in the same direction.
We add on multiples of 360 to rotate a full circle, and we get back to the same direction that 358 degrees points in (almost directly to the east). The variable n is an integer {..., -3, -2, -1, 0, 1, 2, 3, ...}
