The equation s =square root 30fd can be used to find the car's speed s in mph given the length d in feet of a skid mark and the friction factor f of the road. Police measured a skid mark of 90 feet on a dry concrete road. If the speed limit is 35mph, was the car speeding? Explain
Answer:
Yes, the car was speeding the speed limit.
Step-by-step explanation:
The given equation to find the car's speed, s (in mph), is
[tex]s=\sqrt{30fd}[/tex]
where, d is the length of the skid and f is the friction factor.
Police measured a skid mark of 90 feet, so d=90
As the road is dry and of concrete, therefore the friction factor, f=0.8.
So, the speed of the car
[tex]s=\sqrt{30\times0.8\times90} = 46.48[/tex] mph
The speed of the car is 46.48 mph which is more than the speed limit of 35 mph.
Hence, the car was speeding the speed limit.

Contrast the plate movements that cause the stresses in diagrams B and C How did geography affect the way Greeks made their livings?
Answer:
1. Greece made most of their living from the sea.
2. They became fishers and sailors to get food.
3. On their peninsula they had many different ways to trade with other countries.
4. Greece's mountains aren't good for growing crops, although their climate was mild ,so they could grow wheat, barley, olives, and grapes.
5. Since Greece's sea's are dived from one another, it make trading fiercely independent.1. Greece made most of their living from the sea.

What is Angles?
When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
In algebra, two lines can be represented as
a and b are constants in y=ax+ b.
(x,y)
on the Cartesian plane, are points.
Let's say two lines are depicted as
y1 = a1 (x + b1) and y2 = a2 (x + b2)
If and only if, the two lines are parallel.
As any line can be parallel to itself, either b1 is not equal to b2 or b1=b2 and a1=a2.
The characteristic of two simultaneous linear equations that have either no solution or an infinite number of solutions, but not exactly one solution, is another approach to define the term "parallel."
The final definition of the attribute of two lines being "Parallel" states that it is only possible for the X and Y axes to not be parallel to one another. It does not demand for the X and Y axes to be orthogonal to one another or that there be any particular angle between them.
This also applies to the situation of N axes.
Additionally, it is not necessary for Space to be Euclidean or for the 'lines' to be rectilinear.

Step-by-step explanation:
[tex]7y = 8x - 14[/tex]
get rid of the Y and put in a 6
[tex]7(6) = 8x - 14[/tex]
[tex]7 \times 6 = 42[/tex]
[tex]42 = 8x - 14[/tex]
we need to get rid of the negative 14 so its only 8x.
to get rid of 14 on one side you add it to the other
[tex]42 + 14 = 56[/tex]
[tex]56 = 8x[/tex]
to get X by itself have to divide 8 by both sides
[tex]56 + \div 8 = 7[/tex]
[tex]8x \div 8 = x[/tex]

John is on vacation and forgot his video camera. He found a camera shop that rents the cameras. They charge a one-time cleaning fee of $45 and the per day rental charge is $23. If his final bill is $229, how many days did John rent the video camera? Write and solve an equation for John's camera rental.
Given:
One-time cleaning fee = $45
Per day rental charge = $23
Final bill = $229
To find:
The number of days for which John takes video camera on rent.
Solution:
Let the number of days be d.
Rental charge for one day = $23
Rental charge for d days = $23d
Total charges = One-time cleaning fee + Rental charge for d days
[tex]Total=45+23d[/tex]
Final bill is $229. So,
[tex]45+23d=229[/tex]
Subtract 45 from both sides.
[tex]45+23d-45=229-45[/tex]
[tex]23d=184[/tex]
Divide both sides by 23.
[tex]d=\dfrac{184}{23}[/tex]
[tex]d=8[/tex]
Therefore, the required number of days is 8.

line I is the perpendicular bisector of MN. find m
Answer:
m = 68
Step-by-step explanation:
MN bisects it or splits it in half so we know N = M, which we could also write as 8x-12 = 5x+18 because they give us those equations
once you have 8x-12 = 5x+18 you can subtract 5x from both sides, so you will get 3x-12 = 18, then you can add 12 to both sides and you will get 3x = 30. Once you have narrowed down to this you can divide three by both sides making x = 10
Now that we know x =10 we can insert it into the equation
5(10) + 18 = m
50 + 18 = m
m = 68
