What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that top four winners in a golf tournament share the prize money in the ratio 9:5:2:1.
The top prize winner receives $45,000
We need to find the prize money is awarded in total.
9+5+2+1=17
9/17 x = 45000

The function is d(t) = 6cos(πt/6 + π/4) + 6. It models the water depth in meters as a cosine function of time after midnight.
The amplitude of the cosine curve is the difference between the high and low tide water depths, which is 6 m. The period of the cosine curve is the same as the natural oscillation period, which is 12 hours. The high tide occurred at 4:45 a.m., so the phase shift is π/4.Therefore, the function is d(t) = 6cos(πt/6 + π/4) + 6.The cosine function models the water depth d(t) in meters as a function of time t (in hours after midnight) on a particular day.

Recall that in a 45 – 45 – 90 triangle, if the legs each measure x units, then the hypotenuse measures x units
The hypotenuse of the 45-45-90 triangle measures x / √2 units.Identify the given information. The given information is that the legs of a 45-45-90 triangle each measure x units. The question can be solved by following the steps :
1. Use the Pythagorean Theorem to solve for the hypotenuse. The Pythagorean Theorem states that a2 + b2 = c2 where a and b are the legs of the triangle and c is the hypotenuse. In this case, x2 + x2 = c2.
2. Simplify the equation. When two of the same numbers are added together, the sum is twice that number. Therefore, 2x2 = c2.
3. Solve for c. To solve for c, divide both sides of the equation by 2. This yields x2 = c2 / 2.
4. Take the square root of both sides. Taking the square root of both sides yields x = c / √2.
5.The answer to the question is that the hypotenuse of the 45-45-90 triangle measures x / √2 units.

Answer:
b/w 19 & 55
Step-by-step explanation:
average of four equally weighted 100-point tests,
mark has scored 90, 86, and 85 on the first three.
C average = 70 and 79
90+86+85+x = 4*70 = 280, so x=19
90+86+85+x = 4*79 = 316, so x=55
the rosebud flower shop has a basic delivery charge of 5$ plus a rate of 25 cents per mile. The beautiful bouquets shop has a delivery charge of $7 plus a rate of 20 cents per mile.
The price of the delivery is $15 and the mileage is 40.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
Given that the rosebud flower shop has a basic delivery charge of 5$ plus a rate of 25 cents per mile.
Total cost = basic delivery fee + (rate per mile x number of miles)
=$5 + (0.25 x m)
= $5 + 0.25m
The linear expression that represents the total delivery cost from Rosebud Flower Shop ;
Total cost = basic delivery fee + (rate per mile x number of miles)
=$7 + (0.2 x m)
$7 + 0.2m
When the costs are the same, the two expressions would be;
$7 + 0.2m = $5 + 0.25m
$7 - $5 = 0.25m - 0.20
$2 = 0.05m

Jetlag is a condition associated with crossing multiple time zones is experienced by sports tourists from Argentina travelling to Japan.
People who travel quickly between different time zones may experience jet lag, a sleep disorder.
Jet lag causes sporadic sleep problems. It occurs when signals from a new time zone cause the body's biological clock to become out of sync. Feeding times and light exposure are two examples of cues.
The term "jet lag" originated from the fact that it was uncommon to travel far and quickly enough to cause desynchronosis prior to the development of passenger jet aircraft. Propeller-driven travel was slower and covered less ground than jet flights, so it had a negligible impact on the issue.

What Is a Histogram?
A histogram is a graphical representation of data points organized into user-specified ranges.
In graphs (C) and (D), the median value is larger than the mean value as the distribution is skewed to the left which means most values are large but there are few exceptionally small values because of which means shift towards the left and thus the mean is less than the median, or we can say that the median value is larger that the mean value.

6. During the lunch hour rush, the number of vehicles
passing through the drive-thru at the Wendy's at
Appleby Line and Dundas has been determined to be
normally distributed with a mean of 38 vehicles and
a standard deviation of 5.7. What is the probability
that on a given day, exactly 35 vehicles pass through
the drive thru during the lunch hour rush?
Answer:
Step-by-step explanation:
To find the probability that exactly 35 vehicles pass through the drive-thru during the lunch hour rush on a given day, we can use the probability density function of the normal distribution. In this case, the mean is 38 and the standard deviation is 5.7.
The probability of a specific value x in a normal distribution is given by the formula:
P(x) = (1/(σ * √(2π)) * e^((-1/2) * ((x - μ)^2 / σ^2))
Where x is the specific value we are trying to find the probability of, μ is the mean, and σ is the standard deviation.
plugging in the given values, we get:
P(35) = (1/(5.7 * √(2π)) * e^((-1/2) * ((35 - 38)^2 / 5.7^2))
The result is very close to zero, the probability of exactly 35 vehicles passing through the drive-thru during the lunch hour rush is very low, almost impossible.

What is “A Modest Proposal”?Jonathan Swift, a satirist, suggested jokingly in an essay titled "A Modest Proposal" from 1729 that the people of Ireland sell their children as food. A radical or shocking notion is frequently introduced in an ironic way using the term a modest suggestion.
Swift's essay, which is hailed as a masterwork of irony, is officially titled "A Modest Proposal for Preventing the Children of the Poor People in Ireland from Being a Burden to Their Parents or Country, and for Making Them Beneficial to Their Public."
When a proposal takes the form of an essay, it typically proposes a fix for a social or political issue. The adjective "modest" denotes reason or modesty. Because the idea is genuinely absurd, it is humorously used in the title of "A Modest Proposal."
A modest proposal is frequently used in jest to make a point by taking something to its logical conclusion, which highlights a problem. Swift's article, which at the time caused controversy, has since become a satirical mainstay and has influenced a lot of authors.

We can apply midpoint formula to solve for endpoint (N):
[tex]\displaystyle{\text{Midpoint}= \left(\dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2}\right)}[/tex]
Let [tex]\displaystyle{x_1 = 1}[/tex], [tex]\displaystyle{y_1 = 12}[/tex] and Midpoint = (-10,-4). Therefore:
[tex]\displaystyle{\left(-10,-4\right)= \left(\dfrac{1+x_2}{2}, \dfrac{12+y_2}{2}\right)}[/tex]
Solve x with -10 and y with -4:
[tex]\displaystyle{\text{N}\left(x_2,y_2\right) = \left(\dfrac{1+x_2}{2}=-10, \dfrac{12+y_2}{2}=-4\right)}\\\\\displaystyle{\text{N}\left(x_2,y_2\right) = \left(1+x_2=-20, 12+y_2=-8\right)}\\\\\displaystyle{\text{N}\left(x_2,y_2\right) = \left(x_2=-20-1, y_2=-8-12\right)}\\\\\displaystyle{\text{N}\left(x_2,y_2\right) = \left(x_2=-21, y_2=-20\right)}\\\\\displaystyle{\text{N}\left(x_2,y_2\right)=\left(-21,-20\right)}[/tex]

Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4π units. The base of cylinder B has
an area of 9π units.
The dimensions of cylinder A are multiplied by what factor to produce the corresponding dimensions of cylinder B?
4/9
2/3
3/2
9/4
Step-by-step explanation:
To find the factor by which the dimensions of cylinder A were multiplied to produce the corresponding dimensions of cylinder B, we can use the fact that they are similar solids. This means that the ratio of corresponding dimensions is the same for both cylinders.
Since the base of cylinder A has a circumference of 4π units and the base of cylinder B has an area of 9π units, we can use these measurements to find the ratio of the radii of the two cylinders.
The circumference of a circle is given by 2πr, where r is the radius, so the radius of cylinder A is 4π/2π = 2 units.
The area of a circle is given by πr^2, so the radius of cylinder B is sqrt(9π/π) = sqrt(9) = 3 units.
The ratio of the radius of cylinder A to cylinder B is 2/3. Since similar solids have the same ratio for all dimensions, this means that the dimensions of cylinder A were multiplied by a factor of 2/3 to produce the corresponding dimensions of cylinder B.
