2 cities are 120 miles apart. A group that is travelling from one of the cities to the other is already 3/4 of the way. How many miles do the group have left to travel?
Answer in this from, They have blank miles to go
Answer:
They have 30 miles to go
Step-by-step explanation:
1st: you find 3/4 of 120= 90 miles
They have traveled 90 miles
Next, you do 120-90.
You get 30 miles

A movie features dangerous stunts including jumping from a helicopter, riding on the hood of a speeding car, and a number of other acrobatic stunts. The director has hired a stunt double to perform these stunts. In the filming of the helicopter scene, the stunt double is released from a height of 10,000m. Assume the only forces acting on the stunt double are gravity and air resistance. The force of air resistance is assumed to be proportional to the velocity with proportionality constant λ = 10. Assume the stunt double has a mass of 60kg and the force of gravity is −9.81m/s^2.
Required:
Construct a differential equation which models the velocity of the falling stunt double. Explain the reasoning behind how you constructed the model you chose to use. Discuss any potential shortcomings of your model. Describe any initial conditions associated with your model.
Answer:
Vt = 58.86 m/s
Step-by-step explanation:
Stunt height = 10000 m
Stunt mass = 60 kg
force of gravity = 9.81 m/s^2
proportionality constant λ = 10
Forces acting on the stunt double : Gravity and air resistance
attached below is the detailed solution
Vt = 58.86 m/s
What is the equation of the line that passes through the point (-6,-5) and has a slope of 3/2?
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = the slopeb = the y-interceptTo find linear equations, we must solve for m and b and substitute them into slope-intercept form.
Solving the Question
We're given:
Passes through the point (-6,-5)m = [tex]\dfrac{3}{2}[/tex]Input the slope into slope-intercept form:
[tex]y=mx+b\\\\y=\dfrac{3}{2}x+b[/tex]
Solve for the y-intercept by inputting the given point (-6,-5):
[tex]-5=\dfrac{3}{2}(-6)+b\\\\-5=-9+b\\\\4=b[/tex]
Therefore, the y-intercept is 4. Plug this back into our original equation:
[tex]y=\dfrac{3}{2}x+4[/tex]
Answer[tex]y=\dfrac{3}{2}x+4[/tex]

Step-by-step explanation:
Determine which of the lines, if any, are parallel or perpendicular. Explain.
Line a: 4y - 12x = 20
Line b: 3y= -x + 2
Line c: y= 3x - 1
Answer:
Line [tex]a[/tex] and line [tex]c[/tex] are parallel to each other.
Line [tex]b[/tex] is perpendicular to line [tex]a[/tex].
Line [tex]b[/tex] is perpendicular to line [tex]c[/tex].
Step-by-step explanation:
Rewrite the equation of each line in the slope-intercept form [tex]y = m\, x + b[/tex] to find the slope [tex]m[/tex] of that line.
In the slope-intercept form, [tex]y[/tex] need to be on the left-hand side of the equation while [tex]x[/tex] need to be on the right-hand side. The coefficient of [tex]y[/tex] must be [tex]1[/tex]. The slope of the line would then be equal to the coefficient of [tex]x[/tex].
For example, the equation of line [tex]a[/tex] could be rewritten in slope-intercept form as [tex]y = 3\, x + 5[/tex]. The coefficient of [tex]x[/tex] is [tex]3[/tex], so the slope of this line would be [tex]m_{a} = 3\![/tex].
Similarly, rewrite to obtain the the slope-intercept equation of line [tex]b[/tex]: [tex]y = (-1/3)\, x + (2/3)[/tex]. The slope of this line would be [tex]m_{b} = (-1/3)[/tex].
The equation of line [tex]c[/tex] is already in slope-intercept form. The slope of that line would be [tex]m_{c} = 3[/tex].
Let [tex]m_{1}[/tex] and [tex]m_{2}[/tex] denote the slopes of two lines in a Cartesian plane.
These two lines are parallel with if and only if their slopes are the same: [tex]m_{1} = m_{2}[/tex]. These two lines are perpendicular to each other if the product of their slope is [tex](-1)[/tex]: [tex]m_{1}\, m_{2} = (-1)[/tex].In this question, the slope of line [tex]a[/tex] and line [tex]c[/tex] are the same: [tex]m_{a} = m_{c}[/tex]. Thus, line [tex]a\![/tex] and line [tex]c\![/tex] would be parallel.
The product of the slopes of line [tex]a[/tex] and line [tex]b[/tex] is [tex]m_{a}\, m_{b} = 3 \times (-1/3) = (-1)[/tex]. Thus, line [tex]a\![/tex] and line [tex]b[/tex] are perpendicular to each other.
Similarly, line [tex]b[/tex] and line [tex]c[/tex] are perpendicular to each other because the product of their slopes is [tex](-1)[/tex].

Help me please its urgent I need it done asap I need help if anyone could help me solve these problems that would be very helpful! (I'll give brainliest if you can solve all of them!) A company designs a circular dartboard such that the target area in the center is surrounded by a safety margin. Federal law requires that the area of the safety margin must be twice the area of the actual target in the center. If the total radius of the dartboard is 3 feet, what is the radius of the circular target in the center? (you must show the algebra for full credit)
Answer:
the radius of the circular target in the center is 2.12 feet
Step-by-step explanation:
the total area of the dartboard is
π x r² = π x 3² = 9π (28.27 ft²)
The area of the actual target in the center needs to be half of the dartboard (4.5 π) (14.14 ft²)
(Small area : 4.5π = π x r²
Divide both sides by π
4.5 = r²
√4.5 = r
r= 2.12132034....... (2.12 feet)
help me pls ☹️☹️☹️☹️
The slope of a line can be found by graph using rise over run ([tex]\frac{rise}{run}[/tex]). Look at the image below to see what this mean.
Rise = vertical
run = horizontal
I took two clear points on the line as seen below and drew a right angle that formed a right triangle with the line.
Now let's count how many units the rise is (look at the second image). This is 3 units
rise = 3
Count the units of the run (third image). This is 1 unit
run = 1
Let's put these two numbers together in the [tex]\frac{rise}{run}[/tex] form:
[tex]\frac{3}{1}[/tex] or simplified = 3
However, this is not the final answer. This is a negative slope, meaning that when you look at the line from left to right (like when you are reading words) the line reaches from the top left corner to the bottom right corner. A positive slope (reading left to right) reaches from the bottom left corner to top right corner.
To signify that the slope is negative you simply add a negative sign to it:
-3

A rectangular city is 2 miles long and 7 miles wide. What is the distance between opposite corners of the city? The exact distance is ______________ miles How far is it to the closest tenth of a mile? Answer: The distance is approximately ___________ miles.
Answer:
The distance is approximately 10.4 miles.
Answer:
exact distance is = 7.28010988928
rounded to the tenth of a mile is
distance is approximately 7.3 miles
Step-by-step explanation:
hypotenuse of a triangle that's 2 by 7
Pythagorean theorem
a^2 + b^2 = c^2
2^2 + 7^2 = c^2
4 + 49 = c^2
c^2 = 53
c = √53
c = 7.28010988928
tenth of a mile is
c = 7.3

Answer:
A,C,D
Step-by-step explanation:
what is 4 times x and pls explain it for me so then I can explain it
Answer:
4x
Step-by-step explanation:
In algebra, to avoid confusing the multiply sign and x, we always just put the terms next to each other to show that they multiply each other. Here, since x is unknown, we can't find a specific answer and therefore just write it as 4x, which means 4 times x.
Sarah went on a 36 mile trip to a soccer game. On the way back, due to road construction she had to drive 18 miles per hour slower. This made the trip take 1 hour longer. How fast did she drive to the soccer game?
Answer:
Hi Suuuman the answer for your deleted question is OP = 7.75
Step-by-step explanation:
– 2x + 23 and -8 + 2x = 23 - 2x and -8 + 2x = x= 31 /4 =7 3/4 =7.75 measure of OP = – 2 ( 7.75) + 23 = -15.5 + 23 = 7.75
Step-by-step explanation:
Answer for this question Sarah went on a 36 mile trip to a soccer game. On the way back, due to road construction she had to drive 18 miles per hour slower. This made the trip take 1 hour longer. 36 = 18 +18(a+1)How fast did she drive to the soccer game? let the returning speed be x mphgoing to game speed = x+18 Answer is 18 km/h while returning
Step-by-step explanation: Distance = 36
1 hour more while returning
time return - time going = 1
36/x - 36/(x+18) = 1
LCD= x ( x + 18 )
multiply by LCD
36 ( x + 18 ) - 36 x = 1 x ( x + 18 )
36*18=
36 x + 648 - 18 x = 1x ^2 + 18 x
648 = 1 x^2 - 18 x
x^2 + 18 x -648 = 0
x^2 +36x-18x-648=0
x(x+36)-18(x+36)=0
(x-18)(x+36)=0
x=-36 or 18
x =18
18 km/h while returning
while going speed = 18+18 = 36 km/h
