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

Solve the system of equations..
y=x +45
y= 5x + 13

Answers

Answer:

x = 8

y = 53

Step-by-step explanation:

Sub y = x + 45 into the second equation

x + 45 = 5x + 13

Rearrange by collecting the like terms

45 - 13 = 5x - x

32 = 4x

Divide both sides by 4

x = 8

Sub x = 8 into first equation (y = x + 45)

y = 8 + 45

y = 53

X=8 and Y =53 are the values

What is the measure of angle 1 in degrees?

Answers

Answer:

73 degrees

Step-by-step explanation:

The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees.

m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees.

We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107.      180-107= 73 Degrees

Many bank accounts never go below zero. But some banks will allow a negative balance, at least for a short time, called an overdraft. It means someone has taken out, or 'drafted', more money than was in the account to begin with. David's account went into overdraft. To get back to a positive balance, he deposited money at a steady rate of $20.06 per week. After 8 weeks, he had $122.46 in the account. What was the balance when the account went into overdraft?

Answers

Answer:

The balance when the account went into overdraft was -38.02

Step-by-step explanation:

Let x be the balance when the account went into overdraft

To get back to a positive balance he deposited money at a steady rate of $20.06 per week.

Amount deposited per week = $20.06

Amount deposited 8 weeks = [tex]20.06 \times 8 =160.48[/tex]

Now amount in account after 8 weeks =x+160.48

We are given that After 8 weeks, he had $122.46 in the account.

So,x+160.48=122.46

x=122.46-160.48

x=-38.02

Hence The balance when the account went into overdraft was -38.02

What is expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

Given an expression, [tex]\sqrt[3]{x^{10} }[/tex]

to find the equivalent of x¹⁰,

x¹⁰ = x⁵.x⁵

by property aⁿ.aᵇ = aⁿ⁺ᵇ

so x¹⁰ = x⁹.x

=> x⁹⁺¹ = x¹⁰

 [tex]\sqrt[3]{x^{10} }[/tex] =  [tex]\sqrt[3]{x^{9}x }[/tex]

Hence equivalent expression is  [tex]\sqrt[3]{x^{9}x }[/tex].
