Answer:
The length of the section will have 125.8 m
Step-by-step explanation:
Right Triangle
The section of the railroad track rises a height of h=6.8 m for a horizontal run of x=125.6 m.
The height and the horizontal run are the legs of a right triangle which hypotenuse L is the required length of the section of the railroad track.
Applying Pythagora's Theorem:
[tex]L^2=h^2+x^2[/tex]
[tex]L^2=6.8^2+125.6^2[/tex]
[tex]L^2=46.24+15775.36=15821.6[/tex]
[tex]L=\sqrt{15821.6}=125.8[/tex]
The length of the section will have 125.8 m
The Clark family went out to dinner. If their
dinner bill came to $81.50 and they wish to
leave a 18% tip, how much should they tip?
Answer options. $14.69. $12.45. $10.00
Answer:
$14.69
Step-by-step explanation:
To start with, convert the 18% to a genuine number that can be utilized in a figuring. For percent, this is constantly done by essentially isolating the percent (for this situation 18%) by 100%.So, the conversational term "18%" gets 18%/100% = 0.18 regarding a genuine numerical number.
Second, you have to discover what 18% of your $81.50 feast cost is.This is constantly done by duplicating 0.18 by $81.50, or
0.18 x $81.50=$14.69.
Thus, the measure of tip you will leave is $14.69.
This makes the absolute expense of your supper (to compose on your charge slip or other installment)

carlo drive anda pangasinan at the speed of 50 kph on the curve trip back to baguio taking the same richie to drive at this rate of 55 kph what is the average speed of the entire trip?
Answer:
52,5
Step-by-step explanation:
50+55=105
105:2=52,5
Average speed of the entire trip is 52.5 km/hr
Given that;
Speed of car during the way = 50 km/hr
Speed of car in return = 55 km/hr
Find:
Average speed of the entire trip
Computation:
Average speed of the entire trip = Sum of speed / 2
Average speed of the entire trip = [50 + 55] / 2
Average speed of the entire trip = 105 / 2
Average speed of the entire trip = 52.5 km/hr

The sum of two numbers is 28 and their
difference is 4. Find the numbers.
Answer:
Two numbers are 16 and 12
Step-by-step explanation:
Let x and y be the numbers
x + y = 28 (1)
x - y = 4 (2)
y = x - 4 (2')
sub (2') into (1)
x + x - 4 = 28
2x = 32
x = 16
Sub x value into equation (1)
16 + y = 28
y = 28 - 16
y = 12

M is the midpoint of LN. If LN = 90, what is LM?
Answer:
LM = 45
Step-by-step explanation:
M is the midpoint of LN. If LN = 90, what is LM?
L––––––N
From the question
M is the midpoint of LN.
Hence:
L––M––N
Since M is the Midpoint of LN, it means LN is divided in 2 equal parts
LM , MN
So, LM + MN = LN = 90
If LN = 90, LM = 90/2
LM = 45

Which set of polar coordinates names the same point as 5 pi/4
The set of polar coordinates names the same point is (5, 5π/4)
What is polar coordinates ?
"A pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line in a three-dimensional plane are polar coordinates."
According to the question
In general,
In polar coordinates (r, ω) = (-r, ω+π), because when you add π radians to an angle you are turning 180 degrees and then need to change the sign of the radius to preserve the original point.
Then (-5, π/4)
= (5 , π/4 + π)
= (5, 5π/4)
Hence, the polar coordinates names the same point is (5, 5π/4).
