Step-by-step explanation:

Serena started with approximately $173.33 money.

Let's denote the initial amount of money Serena had as S and the initial amount of money Visala had as V.

According to the problem, their combined total was $180, so we have the equation S + V = 180.

After Serena gave Visala $20, Serena's remaining amount became S - 20, and Visala's amount became V + 20.

Visala then gave Serena a quarter of the money she had, which is (V + 20)/4. After this transaction, Serena's total amount became S - 20 + (V + 20)/4, and Visala's total amount became V + 20 - (V + 20)/4.

It is given that after these transactions, they each had the same amount. Therefore, we can set up the equation:

S - 20 + (V + 20)/4 = V + 20 - (V + 20)/4.

Let's simplify and solve for S:

4S - 80 + V + 20 = 4V + 80 - V - 20.

Combining like terms:

4S + V = 3V + 160.

Substituting the value of S + V = 180 from the first equation:

4S + V = 3(180) + 160,

4S + V = 540 + 160,

4S + V = 700.

Now, we have two equations:

S + V = 180,

4S + V = 700.

Subtracting the first equation from the second equation:

4S + V - (S + V) = 700 - 180,

3S = 520,

S = 520/3 ≈ 173.33.

Answer:

Step-by-step explanation:

Brand X needs to use 8.4 oz. of Brand A mixed nuts and 12.6 oz. of Brand B mixed nuts to achieve a 29% peanut content in their 21 oz. bags of mixed nuts.

To determine how much of Brand A and Brand B mixed nuts Brand X needs to use to achieve a 29% peanut content in their 21 oz. bags of mixed nuts, we can set up an equation based on the principle of weighted averages.

Let's assume x represents the amount of Brand A mixed nuts (35% peanuts) that Brand X needs to use, and y represents the amount of Brand B mixed nuts (25% peanuts) that Brand X needs to use.

The total weight of the mixed nuts is given as 21 oz., so we can set up the following equation:

x + y = 21 (Equation 1)

To achieve a 29% peanut content in the final product, we can set up another equation based on the peanut content:

(35% of x) + (25% of y) = 29% of 21 oz.

0.35x + 0.25y = 0.29 * 21 (Equation 2)

Now we have a system of two equations (Equation 1 and Equation 2). We can solve this system of equations to find the values of x and y.

Let's solve the system using the substitution method:

From Equation 1, we have: x = 21 - y

Substituting this into Equation 2, we get:

0.35(21 - y) + 0.25y = 0.29 × 21

7.35 - 0.35y + 0.25y = 6.09

0.1y = 6.09 - 7.35

0.1y = -1.26

y = -1.26 / 0.1

y = 12.6

Substituting this value back into Equation 1, we can find x:

x + 12.6 = 21

x = 21 - 12.6

x = 8.4

Therefore, Brand X needs to use 8.4 oz. of Brand A mixed nuts and 12.6 oz. of Brand B mixed nuts to achieve a 29% peanut content in their 21 oz. bags of mixed nuts.

Answer:

If you begin with the graph for f(x) and then substituted x+3 for x, the effect on the graph will be to move the whole graph 3 units to the left.  

Given that (-9,-1) is on the graph of f(x), and that we are to move the entire graph 3 units to the left, then the coordinate -9 becomes -9-3, or -12:  (-12,-1).

Step-by-step explanation:

There is a 99.73% chance that two people selected at random will not share the same birthday out of 365.

The probability of two people not sharing the same birthday out of 365 can be calculated using the formula:P(A) = n(A)/n(S)where n(A) is the number of favorable outcomes and n(S) is the total number of possible outcomes.

In this case, the favorable outcome is that two people do not share the same birthday, and the total number of possible outcomes is 365 × 365 since each person can have a birthday on any of the 365 days.

To find the number of favorable outcomes, we need to subtract the number of ways two people can have the same birthday from the total number of possible outcomes.

The number of ways two people can have the same birthday is simply 365 since there are 365 possible birthdays.

Therefore, the number of favorable outcomes is:365 × 364

The total number of possible outcomes is:

365 × 365

Thus,the probability of two people not sharing the same birthday out of 365 is:P(A) = (365 × 364)/(365 × 365)P(A) ≈ 0.9973

a) The relation is reflexive, symmetric, and transitive.

b) The relation is not reflexive, symmetric, or transitive.

a) For each watermelon x, x is related to x because the measured weight of x is at least the measured weight of x. Therefore, the relation is reflexive.

For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is also related to x (meaning the measured weight of y is at least the measured weight of x). Therefore, the relation is symmetric.

For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is related to z (meaning the measured weight of x is at least the measured weight of z). Therefore, the relation is transitive.

b) For each watermelon x, x is not related to x because no two watermelons have the same measured weight. Therefore, the relation is not reflexive.

For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is not related to x (meaning the measured weight of y is not at least the measured weight of x).

Therefore, the relation is not symmetric. For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is not related to z (meaning the measured weight of x is not at least the measured weight of z).

Therefore, the relation is not transitive.

The coordinates satisfy the equation x^2 + y^2 = 1. In this specific problem, we found that P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10.

To solve this problem, we need to recall some basic trigonometry concepts related to the unit circle. The unit circle is a circle of radius 1 centered at the origin of a coordinate plane. Any point on the unit circle can be represented by its coordinates (x, y), where x and y are the horizontal and vertical distances from the origin, respectively.

Since the given problem tells us that the x-coordinate of P is positive, we know that x > 0. Additionally, we are given that the y-coordinate of P is -(square root 10)/10. We can use this information to solve for x.

From the Pythagorean theorem, we know that for any point (x, y) on the unit circle, x^2 + y^2 = 1. Substituting y = -(square root 10)/10, we get:

x^2 + ((-sqrt(10))/10)^2 = 1

Simplifying this expression, we get:

x^2 + 10/100 = 1

x^2 = 90/100

x = sqrt(90)/10

Since we know that x is positive, we can simplify this expression further by factoring out a square root:

x = (sqrt(9) * sqrt(10)) / 10

x = (3 * sqrt(10)) / 10

Therefore, the coordinates of point P are:

P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10

We can check our answer by verifying that these coordinates satisfy the equation x^2 + y^2 = 1:

(3 * sqrt(10) / 10)^2 + (-sqrt(10) / 10)^2 = 9/100 + 10/100 = 1/10

Simplifying this expression, we get:

1/10 = 1/10

This confirms that our answer is correct and that P lies on the unit circle.

In summary, to find the coordinates of a point P on the unit circle given its y-coordinate and the fact that its x-coordinate is positive, we can use the Pythagorean theorem to solve for the x-coordinate. We then check our answer by verifying that the coordinates satisfy the equation x^2 + y^2 = 1. In this specific problem, we found that P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10.

To evaluate the triple integral ∫∫∫ xyzdv using cylindrical coordinates, we need to express the integral in terms of the cylindrical coordinates (ρ, φ, z).

The given solid E lies under the paraboloid z = 4 - z² - y². In cylindrical coordinates, this paraboloid equation becomes z = 4 - ρ² - y².

To set up the triple integral, we need to determine the limits of integration for each variable.

Since the solid lies in the first octant, the limits of integration are as follows:

ρ: from 0 to some value ρ₁

φ: from 0 to π/2

z: from 0 to the upper limit of the paraboloid, which is given by the equation z = 4 - ρ² - y².

Now we can set up the triple integral:

∫∫∫ xyzdv = ∫₀^(π/2) ∫₀^ρ₁ ∫₀^(4-ρ²-y²) (ρcosφ)(ρsinφ)z dz dρ dφ

Simplifying the integrand and integrating, we can evaluate the triple integral to obtain the final result.

Note: The specific value of ρ₁ and the complexity of the integration depend on the precise shape of the solid E, which is not provided in the given information. Therefore, the final evaluation of the integral requires additional information about the solid E.
