You used 5 cups of flour to bake 80 cookies. How many cups of flour do you need if you bake 144 cookies?
Answer:
9 cups
Step-by-step explanation:
We can write a ratio to solve
5 cups x cups
------------ = ----------------
80 cookies 144 cookies
Using cross products
5 * 144 = 80x
720 = 80x
Divide by 80
720/80 = 80x/80
9=x
Answer:
7 1/5 cups of flour to mae 144 cookies
Step-by-step explanation:
80/5 = 20 cookies per cup of flour
so 20x7 = 140 and then you still need four more so take the four and another cup of flour and divide the 20 by 4 then you get 5 thus you 7 and 1/5ths cups

How do you find the inverse of a modulo?
You need to find a number that, when multiplied by a given number modulo a certain value, produces a remainder of 1. This can be done using the extended Euclidean algorithm, and the resulting inverse is the residue of the coefficient modulo the modulus.
Finding the inverse of a modulo involves finding a number that, when multiplied by a given number modulo a certain value, produces a remainder of 1. This process is important in modular arithmetic, where calculations are performed with remainders of a fixed integer modulus.
To find the inverse of a modulo, you can use the extended Euclidean algorithm, which is a method for finding the greatest common divisor of two integers.
The steps for finding the inverse of a modulo are as follows:
1. Identify the number you want to find the inverse of (let's call it "a") and the modulus (let's call it "m").
2. Use the extended Euclidean algorithm to find the greatest common divisor of "a" and "m", and the coefficients x and y such that ax + my = gcd(a,m).
3. If gcd(a,m) = 1, then "a" has an inverse modulo "m" and the inverse is given by x mod m.
4. If gcd(a,m) is not equal to 1, then "a" does not have an inverse modulo "m".
In step 3, x mod m represents the residue of x modulo m, which is the unique non-negative integer less than m that is congruent to x modulo m. In other words, it is the remainder when x is divided by m.
For example, to find the inverse of 5 modulo 7, we can use the extended Euclidean algorithm to find that 2(5) + (-1)(7) = 1. Therefore, the inverse of 5 modulo 7 is 2.

The question in the image.
Answer:
500 boxes
Step-by-step explanation:
hey there,
< Since "p" stands for profits, change "p" to 0 (since the question says 0 profits).
Here is how your equation would look like:
\(0 = -n^2 + 300n + 100000\)
Pretend like "n" is "x" since that is the variable we are trying to find here.
Solve for "n". Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
"n" actually ends up equaling 500, -200.
Obviously, negative can't be the answer because you can't have a negative amount of boxes. So 500 boxes would be your answer. 200 CAN'T be your answer either because it is a negative!! >

By applying the substitution t = tan² 0 to B(x, y)= I 25 (sin 0)2x-1 (cos 0)2y-1de, show that dt B(x, y) = √o (1+t)x+y tx-1
The substitution that has been applied to B(x, y) is dt B(x, y) = √(1+t) (1+t)x+y tx-1.
The substitution that has been applied to B(x, y) is t = tan² 0
The substitution for x and y using the trigonometric identities is given by,
x = sin² 0 / cos² 0 = tan² 0 …(1)
y = sin² 0 …(2)
Differentiating both sides of equation (1) with respect to θ, we get
dx / dθ = 2tan 0 sec² 0
Putting the values of x and y in B(x, y), we get
B(x, y) = I 25 (sin 0)² (sin² 0 / cos² 0)-1 (cos 0)² (sin² 0)-1 dθ
= I 25 (sin 0)² / cos² 0 * cos² 0 / sin² 0 dθ
= I 25 tan² 0 dθ
= 25
∫ t dt √1+t
Now, we need to find the value of dt B(x, y) in terms of t.
To find dt B(x, y), we use the chain rule of differentiation and get
dt B(x, y) = ∂B/∂x dx/dt + ∂B/∂y dy/dt
= 25(2 sin 0 cos 0 sin² 0 / cos³ 0) * 2 sin 0 cos 0 sin 0 cos 0 dθ
= 100 (sin 0)³ (cos 0)³ / cos⁴ 0 dθ
= 100 (sin 0)³ / cos 0 dθ
Now, putting the values of x, y, and t, we get
dt B(x, y) = 100 sin³ 0 / cos 0 dθ
= 100 sin³ θ / cos θ dθ
Using the identity 1+t = sec² 0 or cos² 0 = 1 / (1+t), we can rewrite the above integral as
∫ 100 sin³ θ / cos θ dθ
= ∫ (1+t) (1+t)½ dt
Substituting the limits, we get
∫ 100 sin³ θ / cos θ dθ
= ∫ √(1+t) (1+t)x+y tx-1 dt
Answer: dt B(x, y) = √(1+t) (1+t)x+y tx-1.

Given that;
There are some expressions.
Now,
Find all the values after substitute the values as;
a. y = 6x + 8
When x = - 3;
y = 6 × - 3 + 8
y = - 18 + 8
y = - 10

2 = 2x - 2
2x = 2 + 2
2x = 4
x = 2
e. y = 1.5x + 11
When x = - 3;
y = 1.5 × - 3 + 11
y = - 4.5 + 11

A principal wishes to implement a decision that has to be a number between 0 and 1; that is, a decision d needs to be implemented where 0 sdS1. The difficulty for the principal is that she does not know what decision is appropriate given the current state of the economy, but she would like to implement a decision that exactly equals what is required given the state of the economy. In other words, if the economy is in state s (where 0 sS 1) the principal would like to implement a decision d s as the principal's utility Up (or loss from the maximum possible profit) is given by Up--s-d With such a utility function, maximising utility really means making the loss as small as possible. For simplicity, the two possible levels of s are 0.4 and 0.7, and each occurs with probability 0.5 There are two division managers A and B who each have their own biases. Manager A always wants a decision of 0.4 to be implemented, and incurs a disutility Ua that is increasing the further from 0.4 the decision d that is actually implement, specifically U-0.4-d.Similarly, Manager B always wants a decision of 0.7 to be implement, and incurs a disutility UB that is (linearly) increasing in the distance between 0.7 and the actually decision that is implemented - that is Ug--10.7 Each manager is completely informed, so that each of them knows exactly what the state of the economy s is (a) The principal can opt to centralise the decision but before making her decision given she does not know what the state of the economy is - she asks for recomm endation s from her two division mana gers. Centralisation means that the principal commits to implement a decision that is the average of the two recommendations she received from her managers. The recommendations are sent simultaneously and cannot be less than 0 or greater than 1 Assume that the state of the economy s = 0.7. What is the report (or recommendation) that Manager A will send if Manager B always truthfully reports s? (b) Again the principal is going to centralise the decision and will ask for a recommendation from both managers, as in the previous question. Now, however assume that both managers strategically make their recommendations. What are the recommendations rA and rB made by the Managers A and B, respectively, in a Nash equilibriunm
A. Manager A wants the decision to be 0.4, so they would recommend a decision of 0.4 to the principal.
B. The recommendations in the Nash equilibrium would be rA = 0.4 and rB = 0.7.
(a) If Manager B always truthfully reports the state of the economy (s = 0.7), Manager A would send a recommendation that minimizes their disutility Ua. In this case, Manager A wants the decision to be 0.4, so they would recommend a decision of 0.4 to the principal.
(b) In a Nash equilibrium, both managers strategically make their recommendations based on their own utility. Manager A wants to minimize their disutility Ua, which increases as the decision deviates from 0.4. Manager B wants to minimize their disutility UB, which increases as the decision deviates from 0.7.
To find the Nash equilibrium, we need to consider the recommendations made by both managers simultaneously. Let's denote the recommendations as rA (from Manager A) and rB (from Manager B). The principal's decision, d, would be the average of the recommendations, so d = (rA + rB) / 2.
Given that both managers strategically choose their recommendations, they will aim to minimize their disutility. In this case, Manager A would recommend a decision of 0.4 (as it minimizes Ua), and Manager B would recommend a decision of 0.7 (as it minimizes UB). Therefore, the recommendations in the Nash equilibrium would be rA = 0.4 and rB = 0.7.

Let K = (3,8), L = (7,5), and M = (4,1). Find coordinates for the vertices of the triangle that is obtained by using the vector (2, -5] to slide triangle KLM. How far does each vertex slide?
The new coordinates for the vertices of the triangle that is obtained by using the vector (2, -5] to slide triangle KLM are (5,3), (9,0), and (6,-4). The distance each vertex slides is √(29) units.
Given: Let K = (3,8), L = (7,5), and M = (4,1).The vector used to slide the triangle is (2,-5).To find: Coordinates for the vertices of the triangle that is obtained by using the vector (2, -5] to slide triangle KLM.
How far does each vertex slide?Solution:Given that K = (3,8), L = (7,5), and M = (4,1)The vector used to slide the triangle is (2,-5).The formula to find the new coordinates after sliding is:New point = Initial point + vector (Used to slide the point)New coordinates for the vertices K, L and M can be found by adding the vector (2,-5) to the coordinates of the vertices K, L and M respectively.
As the vector used to slide the triangle is (2,-5)New Coordinates of K = K + (2,-5) = (3+2, 8-5) = (5,3)New Coordinates of L = L + (2,-5) = (7+2, 5-5) = (9,0)New Coordinates of M = M + (2,-5) = (4+2, 1-5) = (6,-4)
Thus, the new vertices are K (5,3), L (9,0), and M (6,-4).The distance each vertex slides is equal to the magnitude of the vector used to slide that vertex.
Therefore,Distance each vertex slides = Magnitude of the vector.Distance K slides = Magnitude of the vector (2,-5) = √(2²+(-5)²) = √(29) units.Distance L slides = Magnitude of the vector (2,-5) = √(2²+(-5)²) = √(29) units.Distance M slides = Magnitude of the vector (2,-5) = √(2²+(-5)²) = √(29) units.
Hence, the new coordinates for the vertices of the triangle that is obtained by using the vector (2, -5] to slide triangle KLM are (5,3), (9,0), and (6,-4). The distance each vertex slides is √(29) units.
