The 40-ft-long A-36 steel rails on a train track are laid with a small gap between them to allow for thermal expansion. Determine the required gap d so that the rails just touch one another when the temperature is increased from T1=-20F to T2=90F. Using this gap, what would be the axial force in the rails if the temperature rises to T3=110F? The cross-sectional area of each rail is 5.10 in2

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Sine he runs 2 miles on Monday, we already have a +2.
Then, he runs by a constant rate of 1, which is the constant rate of change per day.
Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2
However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.
y ≥ 6
y = x + 2
Now substitute x + 2 for y.
x + 2 ≥ 6
Subtract 2.
x ≥ 4
This is the inequality. He has to run for at least 4 days.
En un vecindario, un camión de helados pasa cada 8 días y un food truck pasa cada dos semanas, hoy se juntó ambos, ¿en cuántos días se volverán a juntar?
This is the question in English. In a neighborhood, an ice cream truck passes every 8 days and a food truck passes every two weeks, today both came together, in how many days will they get back together?
Answer / Respuesta:
Spanish: La respuesta sería 56 días más.
English: The answer would be 56 more days.
Step-by-step explanation: / Explicación paso a paso:
English: The first time they meet would be at 56 days. So it would be 56 more days until they meet again.
Spanish ( Español): La primera vez que se reúnan sería a los 56 días. Así que pasarían 56 días más hasta que se vuelvan a encontrar.

Is number 1 = 90 ?
Yes you are correct. The diagonals of any kite are perpendicular.
This can be proven by showing that triangle KGH is congruent to triangle KJH through the SSS congruence theorem. From there you break up the triangles focusing on triangle JRK and triangle GRK, now using the SAS rule to conclude that angle JRK = angle GRK. Since those are a linear pair, those angles must be right angles.
Side note: A kite is defined to be any quadrilateral in which it has two pairs of adjacent congruent sides. Not all four sides are the same length though (otherwise we would have a rhombus).

8. Classify 8 as a perfect square, a perfect cube, both, or neither.
Answer:
It's a perfect cube, but not a perfect square.
Step-by-step explanation:
2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.

5-y=-3x in standard form
Answer:
y = 3x + 5
Step-by-step explanation:
The linear formula follows this general form: y = mx + c
Hence, to put 5-y=-3x in standard form, you would rearrange it
-y = -3x - 5
y = 3x + 5
Answer:
3x-y=-5
Step-by-step explanation:
standard form is Ax + By = C
5-y=-3x move the y to the other side by adding it to the -3x
-3x+y=5 The x cant be negative so switch all the signs
3x-y=-5

what fraction represents a repeating fraction?
a) 4/5
B) 1/2
C) 3/4
D) 5/6
please explain too!!
D) 5/6 as 5/6 = 0.833333333333333 and the three will keep repeating
Answer:
D.
Step-by-step explanation:
You meant which one is a repeating decimal.
Okay to find out you would have to divide each.
4 divided by 5 = 0.8
1 divided by 2 = 0.5
3 divided by 4 = 0.75
5 divided by 6 = 0.833333333...
See how the three keeps on repeating? That makes it a repeating decimal.
Hope this helps!!

What is an equation that goes through (12, 5); m = -3
Please help
Answer:
Step-by-step explanation:
Use this formula:
y - y1 = m ( x - x1 )
We are told m = -3 and given the point (12 , 5) ---- > so x1 = 12 and y1= 5
Put these values into the formula above and you get:
y - y1 = m ( x - x1 )
y - 5 = -3 ( x - 12 )
y - 5 = -3x + 36
y = -3x + 36 + 5
y = -3x + 41
f(x) =2x-4 and g(x) =-3x+2 find: f(g(x))
Answer:
[tex]f(g(x))=-6x[/tex]
Step-by-step explanation:
Composite Function
Given f(x) and g(x) as real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
It can simply be found by substituting g into f.
Our functions are:
[tex]f(x)=2x-4[/tex]
[tex]g(x)=-3x+2[/tex]
Substituting g into f:
[tex]f(g(x))=2(-3x+2)-4[/tex]
Operating:
[tex]f(g(x))=-6x+4-4[/tex]
Simplifying:
[tex]\boxed{f(g(x))=-6x}[/tex]

solve for n -8 = 6+n
Answer:
no solution
Step-by-step explanation:
n -8 = 6+n
Subtract n from each side
n-n -8 = 6+n-n
-8 = 6
This is never true so there is no solution
Answer:
n = -14
Explanation:
-8 = 6 + n
move n over to the left side of the equation
-8 - n = 6
-8 - (-14) = 6
Find the difference

10 times the sum of half a number x and 4 is 6
Answer:
-10.4
Step-by-step explanation:
Assume that the number we are looking for is x.
Now, we want to get 10 times the sum of half the number and 6 and equate this expression to 8. Then we can solve for x
step by step
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8
Now solve for x
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4
