In the figure below A; B; C; D; E; F divide the circle into 6 equal parts, find the angle x and y.
The correct values are:
Angle x = 90°
Angle y = 90°
Considering the given information that points A, B, C, D, E, and F divide the circle into 6 equal parts, we can analyze the angles as follows:
Each section of the circle corresponds to an angle of 360° / 6 = 60°.
Now, let's examine angle x and angle y:
Angle x is formed by connecting points A, B, and F. Since A and B divide the circle into two equal parts, the angle AOB is 180° / 2 = 90°. As F divides the remaining portion of the circle, the angle x can be determined as follows:
x = 360° - (180° + 90°) = 90°.
Angle y is formed by connecting points C, D, and E. Similarly, since C and D divide the circle into two equal parts, the angle COD is 180° / 2 = 90°. Thus, the angle y can be calculated as follows:
y = 360° - (180° + 90°) = 90°.
Therefore, the correct values are:
Angle x = 90°
Angle y = 90°

Astronomers have noticed that the number of visible sunspots varies from a minimum of about 10 to a maximum of about 110 per year. Further, this variation is sinusoidal, repeating over an 11 year period. If the last maximum occurred in 2003, write both a sine and a cosine function which models this phenomenon in terms of the time t which represents the year. How many visible sunspots were expected in the year 2020?
60 visible sunspots were expected in the year 2020.
The number of visible sunspots varies sinusoidally, repeating over an 11 year period. The maximum number of sunspots is 110, and the minimum number is 10 per year.
Therefore, the amplitude of the function is (110 - 10) / 2 = 50. The average of the maximum and minimum numbers is (110 + 10) / 2 = 60. The sine function can be written as:f
(t) = A sin(ωt) + C
where A = amplitude, ω = angular frequency, C = vertical shift.
To find A, ω and C, we can use the information given as follows:
f(t) = 50 sin(2π/11(t - 2003)) + 60
Similarly, the cosine function can be written as:
f(t) = A cos(ωt) +
where A = amplitude, ω = angular frequency, C = vertical shift.
To find A, ω and C, we can use the information given as follows:
f(t) = 50 cos(2π/11(t - 2003)) + 60
To find the number of visible sunspots in 2020, we need to substitute t = 2020 in either of the functions. Let's use the sine function.
f(2020) = 50 sin(2π/11(2020 - 2003)) + 60
= 50 sin(2π/11 × 17) + 60
≈ 60.7
Therefore, about 60 visible sunspots were expected in the year 2020.

After someone dies their body temperature decreases due to heat-exchange with the environment, even- tually reaching the ambient temperature. Suppose that the body temperature at the time of death is To- (a) Write down a word equation for the heat-transfer processes occurring following the death of an indi- vidual. (b) Convert your word equation into a mathematical model (i) Carefully state any assumptions that you make. (ii) Define all symbols in your model. (c) (i) Find the temperature of the body (7') as a function of time. (ii) Assume that the individual dies at time t = 0. The body is discovered at time t - ty and that time after the body is discovered is represented by 7. Show that your solution can be written in the form In Z (t) = -A (ta +7)
By comparing this solution to the given form In Z(t) = -A(ta + 7), we can see that A = To - Ta and ta + 7 = kt.
The heat-transfer processes occurring following the death of an individual can be described using a mathematical model. The body temperature decreases over time until it reaches the ambient temperature.
This can be represented by a first-order differential equation. By solving the differential equation, the temperature of the body as a function of time can be obtained. The solution takes the form of an exponential decay with a constant factor.
(a) The word equation for the heat-transfer processes following the death of an individual can be stated as follows: "The rate of change of body temperature with respect to time is proportional to the temperature difference between the body and the environment."
(b) To convert the word equation into a mathematical model, we make the following assumptions:
- The body and the environment are in thermal equilibrium initially.
- The body loses heat solely through conduction and radiation.
- The surrounding environment remains at a constant temperature.
Let T(t) represent the temperature of the body at time t, and Ta represent the ambient temperature. The mathematical model can be expressed as:
dT/dt = -k(T - Ta)
where dT/dt represents the rate of change of body temperature, and k is a constant that determines the rate of heat loss.
(c) (i) To find the temperature of the body as a function of time, we solve the differential equation:
dT/dt = -k(T - Ta)
By separating variables and integrating, we get:
∫(1 / (T - Ta)) dT = -k ∫dt
Solving the integral and applying initial conditions, we obtain:
ln|T - Ta| = -kt + C
where C is the constant of integration.
(ii) Assuming the individual dies at time t = 0 and the body is discovered at time t = ty, we can substitute these values into the solution obtained above:
ln|To - Ta| = -k(0) + C
ln|To - Ta| = C
Therefore, the solution can be written as:
ln|T(t) - Ta| = -kt + ln|To - Ta|
T(t) - Ta = e^(-kt + ln|To - Ta|)
T(t) = Ta + (To - Ta)e^(-kt)
By comparing this solution to the given form In Z(t) = -A(ta + 7), we can see that A = To - Ta and ta + 7 = kt.

Tickets for an Amtrak train cost $21 for children and $35 for adults. Josie paid $2,723 for a total of 91 tickets. How many children tickets and how many adult tickets did Josie buy? Number of Adult tickets sold = Number of Children tickets sold
Josie purchased a total of 91 tickets for an Amtrak train. Children's tickets cost $21 each, and adult tickets cost $35 each. Josie paid a total of $2,723 for the tickets. We need to determine how many children's tickets and how many adult tickets Josie bought.
Let's assume Josie bought x children's tickets and y adult tickets. According to the given information, the total number of tickets is 91, so we have the equation:
x + y = 91 (Equation 1)
The cost of each child's ticket is $21, and the cost of each adult ticket is $35. The total amount Josie paid, $2,723, can be expressed as:
21x + 35y = 2723 (Equation 2)
To find the values of x and y, we can solve this system of equations (Equations 1 and 2). There are various methods to solve a system of equations, such as substitution or elimination. Let's use the substitution method in this case.
From Equation 1, we can rewrite it as x = 91 - y. Substitute this value of x into Equation 2:
21(91 - y) + 35y = 2723
Expanding and simplifying:
1911 - 21y + 35y = 2723
14y = 812
y = 58
Now substitute the value of y back into Equation 1 to find x:
x + 58 = 91
x = 33
Therefore, Josie bought 33 children's tickets and 58 adult tickets.

list all of the integers between and that are congruent to 1 modulo 22.
The integers between 0 and 100 (inclusive) that are congruent to 1 modulo 22 are: 1, 23, 45, 67, 89
To list all the integers between 0 and 100 (inclusive) that are congruent to 1 modulo 22, we can start with 1 and add multiples of 22 until we reach the upper limit.
The integers congruent to 1 modulo 22 can be expressed as:
1 + 22n, where n is an integer.
Let's calculate the values:
1 + 22(0) = 1
1 + 22(1) = 23
1 + 22(2) = 45
1 + 22(3) = 67
1 + 22(4) = 89

Nicholas uses 1 3/4 teaspoons of sugar to make 1 cup
of hot cocoa. How much sugar
should he use to make 6 cups of hot cocoa?
Answer:
10 1/2 (ten and a half) teaspoons
Step-by-step explanation:
If 1 3/4 teaspoons of sugar can make 1 cup of hot cocoa
then how many teaspoons of sugar can make 6 cups?
that is,
1 3/4 tsps = 1 cup of hot cocoa
? = 6 cups of hot cocoa
when you cross multiply
6 * 1 3/4
1 3/4 in whole number is 7/4
6 * 7/4 = 21/2
21/2 expressed in fraction is 10 1/2
therefore 10 1/2 teaspoons of sugar will make 6 cups of hot cocoa.

Data shows that the probability of dying from cardiovascular disease is 0.45 and that the probability from dying of cancer is 0.22. What is the probability of dying from some other cause?
The sum of all probabilities of dying from all causes is equal to one. Hence, the probability of dying from some other cause is 1 - 0.45 - 0.22 = 0.33.Probabilities are numerical estimates of the chance of a given outcome occurring.
\Probability theory is the study of the ways in which probabilities can be calculated or estimated, as well as the mathematical laws that govern them. It's critical in virtually every area of human endeavour that includes elements of uncertainty or chance, from the weather to finance to the results of an election.
Therefore, from the above given data, it is quite clear that the probability of dying from some other cause is 0.33.
