Step-by-step explanation:
distance / rate = time s = plane speed w = wind speed
Flying with wind 1053 / ( s+ w) = 1.75
solve for s = 601.714 -w
Flying against wind 1053 / (s-w) = 2.75 sub in for s (above)
1053 / ( 601.714 - w -w ) = 2.75
solve for w = 109.27 mi/hr
sub this 'w' into one of the equations to solve for 's'
1053 / ( s + 109.273) = 1.75 shows s = 492.44 mi/hr

The solution of the system of equations is x = -5/17 and y = -16/17.
To do this, we can use a method called substitution. In this method, we solve one equation for one variable in terms of the other variable, and then substitute this expression into the other equation. This results in a new equation with only one variable, which can be solved to find the value of that variable. Once we know the value of one variable, we can substitute it into either equation to find the value of the other variable.
Let's apply this method to your system of equations:
5x - y/2 = -1 (Equation 1)
3x - 2y = 1 (Equation 2)
First, we'll solve Equation 1 for y in terms of x:
5x - y/2 = -1
y/2 = 5x + 1 (Add y/2 to both sides)
y = 10x + 2 (Multiply both sides by 2)
Now we substitute this expression for y into Equation 2:
3x - 2(10x + 2) = 1 (Substitute y = 10x + 2)
3x - 20x - 4 = 1
-17x = 5
x = -5/17
Now that we know the value of x, we can substitute it into either Equation 1 or Equation 2 to find the value of y. Let's use Equation 1:
5x - y/2 = -1
5(-5/17) - y/2 = -1
-25/17 - y/2 = -1
y/2 = -1 + 25/17
y/2 = -8/17
y = -16/17

What is percent rate of change?A measure known as the percent rate of change quantifies the amount of change in a quantity over time and is given as a percentage of the initial number. It is frequently used to keep tabs on population growth, shifts in the financial markets, and other occurrences.
You must first determine the amount of change in the quantity (often done by deducting the beginning value from the final value) in order to compute the percent rate of change. To calculate the percent rate of change, divide this amount of change by the starting value, multiply the result by 100, and add a percent sign.
[tex]f(t) = 1.18^t:[/tex] 16.99% is the percent rate of change per unit (t). This increase is exponential.
[tex]g(t) = 2^{-2t}:[/tex] Approximately -9.1% of a percent rate of change per unit, t. The decline is exponential.
[tex]h(t) = 1.19^{\frac{t}{10} }:[/tex] The average percent rate of change for unit t is around 8.5 percent. This increase is exponential.

Angles in a Triangle
Answer:
55
Step-by-step explanation:
The first we need to do is find the other angle measures. The left angle must be supplementary with 110, so it must measure 70. The right angle must be supplementary with 125, so it must measure 55. The sides of an angle add up to 180, so 180-70-55= 55
The angle of x is 55°.
There is 180° in a triangle. First, we need to calculate the angles of the other two sides. A straight line also forms 180°. Therefore the first angle will be
180 - 110= 70°
The second angle will be
180 - 125 = 55°
Angles of the triangle excluding x will be
70 + 55 = 125°
Since there is 180° in a triangle, x will be
180 - 125= 55°

The test statistic is z = 0.52 and p-value (0.3015) is greater than the significance level (0.05)
Given data ,
Under the premise that the null hypothesis is true, the p-value is the likelihood of witnessing a test statistic that is as severe as the one computed or even more extreme. The p-value of a right-tailed test is the likelihood of seeing a test statistic that is higher than or equal to the computed test statistic.
We can compare the test statistic to the critical value or use a conventional normal distribution table to calculate the p-value given that the test statistic is z = 0.52 and the significance threshold is 0.05
Looking up the p-value corresponding to z = 0.52 in a standard normal distribution table or using a calculator, we find that the p-value is approximately 0.3015.
Since the p-value (0.3015) is greater than the significance level (0.05), we fail to reject the null hypothesis.

Frank used 2 1/3 gallons of gas on Saturday and 3 2/5 gallons of gas on Sunday. How many gallons did he use on the two days combined? Write your answer as a mixed number in simplest form.
Frank used a total of 2 14/15 gallons of gas on Saturday and Sunday combined.
To find the total amount of gas Frank used on both days, we need to add the amount of gas he used on Saturday and Sunday.
First, we need to make sure that both quantities are in the same form. We can convert the mixed number 2 1/3 to an improper fraction by multiplying the whole number by the denominator and adding the numerator. This gives us:
2 1/3 = (2 x 3 + 1)/3 = 7/3
Next, we can add the two quantities by finding a common denominator. The lowest common denominator for 3 and 5 is 15. So, we can write:
7/3 gallons + 3 2/5 gallons = (35/15 + 9/15) gallons
= 44/15 gallons
To simplify the answer, we can express the mixed number as a whole number and a proper fraction by dividing the numerator by the denominator. This gives us:

Does point A on the graph represent a pair of possible values of m and w? Yes or no because 20 is or is not equal to 2.5 times 1.
Answer:
Yes, point A on the graph represents a pair of possible values of m and w because it satisfies the equation w = 2.5m + 5.
To confirm this, we can substitute m = 20 into the equation to get:
w = 2.5(20) + 5
w = 50 + 5
w = 55
So the coordinates of point A are (20, 55), which represents a possible value of m and w that satisfies the equation.

A garden is in the shape of a square with a perimeter of 36 feet. The garden is surrounded by two
fences. One fence is around the perimeter of the garden, whereas the second fence is 2 feet from th
first fence on the outside. If the material used to build the two fences is $1.15 per foot, what was the
total cost of the fences?
The perimeter of the square garden is 36 feet, which means that each side of the square is 36/4 = 9 feet long. Therefore, the total cost of the fences is $92.
How is Perimeter calculated?The length of the outer fence, which is 2 feet away from the garden, is equal to the perimeter of a larger square with sides that are 2 feet longer than the sides of the original garden.
So, the length of the outer fence is 4(9+2) = 44 feet.
The length of the inner fence, which is around the perimeter of the garden, is equal to the perimeter of the original square garden, which is 4(9) = 36 feet.
The total length of both fences is the sum of the lengths of the inner and outer fences:
36 + 44 = 80 feet.
The cost of the fences is the total length of both fences multiplied by the cost per foot:
80 x $1.15 = $92.
Therefore, the total cost of the fences is $92.

Let suppose, base of the triangle = x
Then, according to the problem, the height of the triangle is x - 3.
We know the area of triangle is,
[tex]A = \frac{1}{2}*b*h[/tex] ; here A is the area, h is the height and b is the base.
Put the given values,
[tex]90 = \frac{1}{2} *(x)*(x-3)[/tex]
Multiplying both sides by 2:
180 = x² - 3x
x² - 3x - 180 = 0
(x - 15)(x + 12) = 0
Therefore, either x - 15 = 0 or x + 12 = 0.
If x - 15 = 0, then x = 15, which is the length of the base of the triangle.
If x + 12 = 0, then x = -12, which is not a valid solution since the length of a side of a triangle cannot be negative.
Therefore, the length of the base of the triangle is 15 feet.
The height of the triangle (x - 3), so the height is: (15 - 3) = 12 feet.
Hence, the length of the base is 15 feet and the height is 12 feet.

Karen can fit 25 vinyl records of diameter 12 in. inside a cylindrical carton with the same diameter.
We know that;
Volume of cylinder is,
⇒ V = πr²h
Hence, We get;
100π = π × (12/2)² × h
100 = 36h
h = 100 / 36
h = 50/18

Solve each equation
tan([tex]\frac{x}{2}[/tex] - [tex]\frac{\pi }{2}[/tex]) = [tex]\sqrt{2}[/tex]
Also what is the value of arctan([tex]\sqrt{2}[/tex])
Give in the form x=[tex]\pi[/tex]+[tex]\pi[/tex]n
The value of arctan(√2) for the equation tan(x/2 - π/2) = √2 in the form x=π +πn is given by arctan(√2) = π/4 + πn, where n is an integer.
Equation is equal to,
tan(x/2 - π/2) = √2
By using the identity for tangent of half angle,
tan(x/2 - π/2)
= 1/cot(x/2 - π/2)
= 1/(-tan(x/2))
So the equation becomes,
1/(-tan(x/2)) = √2
Multiplying both sides by -1, we get,
tan(x/2) = -1/√2
= -√2/2
Now use the inverse tangent function (arctan) to find x/2,
arctan(-√2/2) = -π/4
Since x/2 - π/2 = -π/4, we have,
⇒ x/2 = -π/4 + π/2
= π/4
The solutions for x are x = π/2 + 2πn, where n is an integer.
Now let us find the value of arctan(√2),
arctan(√2) is the angle whose tangent is √2.
Since tan(π/4) = √2, we have,
arctan(√2) = π/4 + πn, where n is an integer.
Therefore, the value of arctan(√2) in the form x=π +πn is equal to
arctan(√2) = π/4 + πn, where n is an integer.

A glass contains 320 cm³ of milk. The mass of the milk is 330 g. Calculate the density of the milk in kilograms per cubic metre (kg/m³). Give your answer to the nearest integer.
If glass contains 320 cm³ of milk, the mass of the milk is 330 g, the density of the milk is approximately 1031 kg/m³.
Density is defined as the mass per unit volume of a substance. To find the density of milk in kg/m³, we need to convert the given volume and mass to the appropriate units.
First, we need to convert the volume from cm³ to m³. Since 1 m = 100 cm, 1 m³ = (100 cm)³ = 1,000,000 cm³. Therefore, we can convert 320 cm³ to m³ by dividing by 1,000,000:
320 cm³ ÷ 1,000,000 = 0.00032 m³
Next, we need to convert the mass from grams to kilograms. Since 1 kg = 1000 g, we can convert 330 g to kg by dividing by 1000:
330 g ÷ 1000 = 0.33 kg
Now that we have both the mass and volume in appropriate units, we can calculate the density by dividing the mass by the volume:
Density = mass ÷ volume = 0.33 kg ÷ 0.00032 m³ ≈ 1031 kg/m³

Answer:
-4.01, -4, -7,
Step-by-step explanation:
It's as simple as substituting and solving. However, this one isnt so simple. The problem tries to trick you because each of the numbers that is provided is supposed to be substituted for x. For example, one of the numbers is 4, which means the equation would be -(4)+6[tex]\geq[/tex]10. But in this problem, the 4 would become a negative four due to the negative sign next to the x. In contrast, the negative numbers in the list provided would then become positive because negative times a negative is positive.
