Answer:
The coal freight train is traveling at a faster speed.
Step-by-step explanation:
The complete question is attached.
Both trains delivery can be represented using coordinates, where y represent the distance traveled and x represent the hours.
For the coal freight train, we can take two points. Let us use (1, 49) and (3, 147). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-49=\frac{147-49}{3-1} (x-1)\\\\y-49=49(x-1)\\\\y=49x[/tex]
For the grain freight train, we can take two points. Let us use (0, 0) and (3, 135). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{135-0}{3-0} (x-0)\\\\y=45x[/tex]
Since the coal freight train has a slope (49) higher than the grain freight train (45), hence the coal freight train travels faster

The velocity V of an object dropped from a tall building is given by V = V64d, where dis
the distance, in feet, the object has dropped. Find the distance when the velocity is
32 ft/sec.
Answer:
d = 0.0625 m
Step-by-step explanation:
The velocity of an object dropped from a tall building is given by :
[tex]v=\sqrt{64d}[/tex]
Where
d is the distance in feet
We need to find the distance when the velocity is 32 ft/s
Rearranging for d,
[tex]v^2=64d\\\\d=\dfrac{64}{v^2}[/tex]
Put v = 32 ft/s
[tex]d=\dfrac{64}{32^2}\\\\d=0.0625\ m[/tex]
So, the required distance is 0.0625 m.

Evaluate 18 divided by q when q=1/2
Question:
Evaluate 18 divided by q when q = 1/2
__________________________________________________
Answer:
18 divided by q
= 18/q
When q = 1/2,
= (18) / (1/2)
The 2 from the denominator of (1/2) will go up to the numerator of (18) / (1/2). We will be left with,
= (18 * 2) / (1)
= 36/1
= 36
Drag the choices into the boxes to explain how all real numbers have a decimal expansion. The decimal forms of some real numbers, like Response area, terminate, while the decimal forms of other real numbers, like Response area, do not terminate, but have a repeating pattern. Still other real numbers, like Response area, have decimal forms that neither terminate nor repeat.
Answer:
[tex]\frac{3}{16}[/tex]
[tex]4\frac{2}{11}[/tex]
[tex]\sqrt{5}[/tex]
Step-by-step explanation:
[tex]\sqrt{5}=2.2360679...\\\\\frac{3}{16}=0.1875\\\\4\frac{2}{11}= \frac{46}{11}=4.18181818...[/tex]
The decimal forms of some real numbers, like [tex]\frac{3}{16}[/tex], terminate, while the decimal forms of other real numbers, like [tex]4\frac{2}{11}[/tex], do not terminate, but have a repeating pattern. Still other real numbers, like [tex]\sqrt{5}[/tex], have decimal forms that neither terminate nor repeat.

Answer: The walking path around it.
Step-by-step explanation:
Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:
A^2 + B^2 = H^2
or
H = √(A^2 + B^2)
Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge
Here we can see that:
A = 1170 ft
B = 520 ft
Then:
H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft
Now, let's compute the costs.
For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:
Cost of the bridge = (1280.4)*$11 = $14,084.4
And for the walking path, the cost is $6 per foot, then the total cost of the path is:
Cost of the path = (520 ft + 1170 ft)*$6 = $10,140
We know that the bridge is preferred if it is within the range of $1500 for the path's cost.
This range is:
($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)
Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

Answer:
y=1/3x -4
Step-by-step explanation:
3y-x=-12
y= 1/3x-4
m=1/3
(gradient is the same since its parallel)
y=mX+c
(2) = 1/3(18) + c
2 = 6 + c
2 - 6 = c
c= -4
(y-intercept)
Therefore: y=1/3x-4

A circle is centered at (0,0) and has a radius of 2\sqrt{3}
Where does the point M(−3,2) lie?
Answer:
Outside of the circle
Step-by-step explanation:
First, find the equation of the circle by plugging in the center point and radius:
(x - h)² + (y - k)² = r²
(x - 0)² + (y - 0)² = ([tex]2\sqrt{3}[/tex])²
x² + y² = 12
Plug in point M to see where it lies:
x² + y² = 12
(-3)² + (2)² = 12
9 + 4 = 12
13 ≠ 12
Since this statement is false, point M lies outside of the circle.
Can someone actually help me with this
Answer: X = 30*
All circles = 360*
we can subtract 260 from that because we know the length of one so we know the other is 130.
We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50

Please help I need to pass my class
Answer:
Step-by-step explanation:
sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{7}{14}[/tex]
= [tex]\frac{1}{2}[/tex]
= 0.5
cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{12.124}{14}[/tex]
= 0.866
tanD = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{7}{12.124}[/tex]
= 0.577
Since, sinE = cosD
Therefore, sinE = 0.866
Since, cosE = sinD
Therefore, cosE = 0.5
Since, tanE = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{12.124}{7}[/tex]
= 1.732
Find the measure of the bold angle.- pls help
Answer:
I am not sure what your "bold angle" is, but x=8.
Step-by-step explanation:
5x+5+16x+7=180
21x+12=180
21x-12=180-12
21x=168
168/21=8
x=8
What is the slope of the line that contains the point (3, 9) and (3, 4)?
A) 6/5
B) 6/13
C) Zero
D) Undefined
Answer:
D) Undefined slope
Step-by-step explanation:
Note that the x-coordinate (3) of both given points is 3. This means that the two points lie on a vertical line. The slope of a vertical line is undefined.
The correct answer is D) Undefined slope

A system of linear equations has infinitely many solutions. What is known about the slopes and y-intercepts of the graphed equations? Explain your reasoning.
Answer:
The answer is below
Step-by-step explanation:
The graph of a linear function can be represented as:
y = mx + b;
where y and x are variables, m is the slope of the graph and b is the y intercept.
A system of linear equations has infinitely many solutions, when the lines overlap at every point. In other words, they're the same exact line, having the same equation when simplified.
This means that they have the same slope and y intercepts

Answer:
The answer is 15
Step-by-step explanation:
add 5 plus 2 equals 7 then divide 10 with 5 equals 2 then 2 times 2 times 2 equals 8 then you have your answer 8 plus 7 equals 15
and the reason I said 2 times 2 times 2 was because there is a 3 and you have to do that 3 times

The following two triangles are similar. Find x.
Answer and Step-by-step explanation:
Since we know that the triangles are similar, we can find the value of x. It appears that the lighter triangle is dilated to be smaller than the darker triangle.
So, We would divide 45 by 9 to find the scale factor.
45 divided by 9 is 5.
Now, we divide 25 by this to find x.
25 divided by 5 is 5.
x is equal to 5.
