Just need some help with this question.
n200080 [17]

The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.

<h3>what is speed?</h3>

Speed is the time rate at which an object is moving along a path

Let the speed of southbound train is x miles/hour

so, northbound train has speed of x+10 miles/hour.

then, Speed of both train = Total distance/ total time

(x+10+x)=210/5

2x+10= 210/5

2x+10= 42

2x= 32

x= 16 miles per hour (southbound train)

northbound train:  16+10=26 miles per hour

Q5 Q35.) Let sin t = a​, cos t = b​, and tan t = c. Write the expression in terms of​ a, b, and c.
pychu [463]
Sine is an odd function, meaning that sin(-x)=-sin(x)  &forall; x &in; R.
=>
sin(-t)-sin(t)=-sin(t)-sin(t)=-2sin(t)=-2a

If the perimeter of isosceles ΔABC is 45 and side AC is 11, give one possible value for the length of side BC.
solmaris [256]

Hello from MrBillDoesMath!

Answer:

23

Discussion:

In ΔABC side AC is 11, but as the triangle is isosceles the other leg also has length 11. Let the third, unknown side, be called x. Then

11 + 11 + x = Perimeter = 45.

11 + 11 + x = 45                 => as 11 + 11 = 22

22 + x = 45                      => subtract 22 from both sides

x = 45 -22 =  23

Thank you,

MrB
