When Theresa walks at a pace of 88 steps per minute, it takes her 90 minutes to walk the trail. If she alters her pace to 33 steps per minute, how long will it take her to walk the trail?
Answer: 33 minutes
Step-by-step explanation:
Hi to answer this question we have to write a proportion
Speed rate = 88 step per minute
Time = 90 minutes
So, the proportion is 88 step/min / 90 minutes
For 33 steps per minutes = 33 / x minutes
88/90 = 33/x
solving for x:
x= 33/ (88/90)
x = 33.75 = 33 minutes.

Step-by-step explanation:
[tex] \sin \: 33 \degree = \frac{a}{4} \\ 0.544639035 = \frac{a}{4} \\ a = 4 \times 0.544639035 \\ a = 2.17855614 \\ a = 2.18 \: units[/tex]
The sum of the angles in a triangle is always 180 degrees. This fundamental concept helps in calculating unknown angles in triangles.
Triangle Angle Sum Theorem: The sum of the angles in a triangle is always equal to 180 degrees.
Explanation: In any triangle, the three interior angles add up to 180 degrees. This theorem is fundamental in geometry and can be used to solve for unknown angles in triangles.
Example: If two angles in a triangle are 30 degrees and 60 degrees, the third angle can be found by subtracting the sum of the given angles from 180, which gives 90 degrees.

what is the input for inverse trigonometric functions
Answer:
An inverse trigonometric function is a function in which you can input a number and get/output an angle (usually in radians). It is the inverse function of the basic trigonometric functions.
Step-by-step explanation:
Trigonometric functions are derived from ratios of certain sides of a right triangle in reference to an angle. The graph of which is a wave, with amplitude in the y-axis and angle in the x-axis. We will first define the sine function written as:
sin(θ)=oppositesidehypotenuse
As we can see, the sine function, together with all the other trigonometric functions, relates an angle to the ratio of an opposite side and the hypotenuse of right triangle. The input here is an angle, and the output is a ratio. Therefore, the inverse process to this is actually just a reverse process.
Let
y
=
s
i
n
(
θ
)
y=sin(θ)
Then inverse trigonometric function outputs an angle. However, we can set y to its original value via transitivity:
s

sin−1(y)=θsin−1(oppositesidehypotenuse)=θ
Thus we see, that the input to an inverse trigonometric function is a unitless ratio of two sides of a representative right triangle.
The input to an inverse trigonometric function is a unitless ratio of two sides of a representative right triangle.
We need to find what is the input for inverse trigonometric functions.
What is the input for an inverse trigonometric function?An inverse trigonometric function is a function in which you can input a number and get/output an angle (usually in radians).
The inverse trigonometric functions do the same thing as the inverse trigonometric relations, but when an inverse function is used, because of its restricted range, it only gives one output per input--whichever angle lies within its range.
Example:
Inverse sine of 1/2 is the angle of 30°
That is, [tex]sin^{-1}(\frac{1}{2} )=30^o[/tex]
As we can see, the sine function, together with all the other trigonometric functions, relates an angle to the ratio of an opposite side and the hypotenuse of the right triangle. The input here is an angle, and the output is a ratio. Therefore, the inverse process to this is actually just a reverse process.
Therefore, the input to an inverse trigonometric function is a unitless ratio of two sides of a representative right triangle.

Explain at least one reason why knowing the surface area or the volume of your rectangular prism important?
(If this helps my prism is L=6 W=2 H=2)
PLEASE HELP
Answer:
Surface Area=56 Square UnitsVolume=24 Cubic UnitsStep-by-step explanation:
The surface area of a rectangular prism enables you to know the amount of material needed to build the prism. In your prism, as shown by the calculation below, you will need 56 Square Units of Material to build a prism of that dimension.
The volume on the other hand helps you to know the quantity of material that will fit into the prism. Similarly, in your prism, you can fit in 24 cubic units of load inside the rectangular prism.
Given your prism with dimensions L=6 W=2 H=2

There's a subset of Pythagorean Triples where the long leg is one less than the hypotenuse,
a^2+b^2 = (b+1)^2
a^2 + b^2 = b^2 + 2b +1
a^2=2b+1
So we get one for every odd number, since the square of an odd number is odd and the square of an even number is even.
b = (a^2 - 1)/2
a=3, b=(3^2-1)/2=4, c=b+1=5
a=5, b=(5^2-1)/2 =12, c = 13
a=7, b=24, c=25
a=9, b=40, c=41
a=11, b=60, c=61
a=13, b=84, c=85
It's good to be able to recognize Pythagorean Triples when we see them.
Otherwise we'd have to work the calculator:

In rhombus ABCD, m∠XCB = 6a − 2 and m∠XBC = 4a + 12. What is the measure of ∠XCB?
Answer: Angle XCB = 46 degrees ( ∠XCB = 46°)
Step-by-step explanation: Please refer to the picture attached for details.
A rhombus basically is a parallelogram with a diamond shape. All four sides have equal length, opposite sides are parallel and opposite angles are equal.
The sides have been labelled ABCD as stated in the question, and the point X is extended to point B to form angle XBC and also extended to point C to form angle XCB. Upon careful observation we shall notice that a triangle has been formed with sides BXC and angle X is a right angle, which measures 90 degrees.
The sum of angles in a triangle equals 180, therefore,
Angle XBC + Angle XCB + Angle X = 180
Substituting for the given values we now have the following;
4a + 12 + 6a - 2 + 90 = 180
10a + 10 + 90 = 180
10a + 100 = 180
Subtract 100 from both sides of the equation
10a = 80
Divide both sides of the equation 10
a = 8
If XCB = 6a - 2,
Substitute for the value of a
XCB = 6(8) - 2
XCB = 48 - 2
XCB = 46
Therefore angle XCB measures 46 degrees.

Express 15 seconds as a fraction of 2 hours
To express 15 seconds as a fraction of 2 hours, first convert 2 hours to seconds, which is 7200 seconds. The fraction is thus 15 / 7200, and simplified, it is 1/480.
Explanation:To express 15 seconds as a fraction of 2 hours, we need to convert both quantities to the same unit.
There are 60 seconds in a minute and 60 minutes in an hour, so 2 hours is equivalent to 2 × 60 × 60 = 7200 seconds.
The fraction representing 15 seconds out of 2 hours is therefore 15 / 7200.
Simplifying this fraction, we divide numerator and denominator by the greatest common divisor (15), which gives us 1 / 480. Thus, 15 seconds is 1/480 of 2 hours.
Now let's review some additional units of time:
15 minutes + 60 minutes = 75 minutes,10 minutes + 20 minutes = 30 minutes,15 seconds + 45 seconds = 60 seconds or 1 minute.For conversion, 1 hour is equal to 60 minutes, so if we have 100 minutes, we can represent it as 1 hour 40 minutes. Similarly, the sum of 1 hour 55 minutes and 45 minutes is 2 hours 40 minutes.
It's important to remember to start your subtractions by subtracting seconds from seconds and minutes from minutes, borrowing from the larger units when necessary.

Directions: Using the image and the scenario provided in the trajectory scenario activity Question #1, determine the trajectory the bullet traveled. Drawings are not to scale. Question #1. A bullet from a sniper struck and killed a controversial political figure who was waiting in a nearby car as a passenger. Crime scene investigators are unsure what floor of the building the shot came from. The first floor of the hotel is 25 ft. high. Each subsequent floor is 15 ft. tall. Entry point on car window above horizontal = 12 in. Distance from car window to victim = 42 in. Distance from building to victim’s car = 350 ft. Using the measurements from the scene, determine what floor of the building the shooter came from. Tips: Convert units to feet, Complete ratio to find the height of the shooter in feet. To determine the floor number from feet: 25 + 15x, The floor number = add one to x. Which means the shooter was on which floor? a 5 b 6 c 7 d 8
Answer: 6 floors
Step-by-step explanation: Given that:
The first floor height = 25ft
Where each subsequent floor is 15 ft. tall.
Entry point on car window above horizontal = 12 in.
Distance from car window to victim = 42 in.
Distance from building to victim’s car = 350 ft.
Using similarity in angle method, we have
(25 + 15x)/350 = 12 in/42 in
Convert inches to feet by dividing the value by 12
(25 + 15x)/350 = 1/3.5
Cross multiply
3.5(25 + 15x) = 350
87.5 + 52.5x = 350
52.5x = 350 - 87.5
52.5x = 262.5
X = 262.5/52.5
X = 5
Therefore,
The floor number = 1 + 5 = 6 floors
To determine the shooter's floor number, we divide the distance from the building to the victim's car by the height of each floor. Using the given measurements, the shooter was on the 6th floor.
Explanation:To determine the floor number from feet, we need to divide the distance from the building to the victim's car by the height of each floor. The height of the first floor is given as 25 ft, and each subsequent floor is 15 ft taller than the previous. We calculate the number of floors using the formula: floor number = (distance from building to car - height of first floor) / height of each subsequent floor. Plugging in the given values, we find that the shooter was on the 6th floor, so the correct answer is option b) 6.
