Someone me. serious answers only.

So, we need to know what the unit rate. Basically, how many miles in 1 hour is what we are looking for. To do this, we must use the data given. Let's do 2 hours. So, we have to divide 2 hours by 36 miles. 36/2 is 18. So, 18 miles per hour is our unit rate. Now, we need to find how many miles in 8 hours. So, we need to multiply 18 miles (because that's 1 hour) by the number of hours we need, which is 8 in this case. So, 18*8 is equal to 144. So, 144 miles is the distance traveled in 8 hours. Hope this helped! 

Width: w=6 cm
Depth: d=4 cm
Height: h=7 cm
Side edge: s=?

s=sqrt [ (w/2)^2+h^2 ]
s=sqrt [ (6 cm / 2)^2+(7 cm)^2]
s=sqrt[ (3 cm)^2 + 49 cm^2 ]
s=sqrt (9 cm^2+49 cm^2)
s=sqrt (58 cm^2)
s=sqrt(58) cm
s=7.615773106 cm
s=7.6 cm

 The length of the side edge, s, of the triangular prism is 7.6 cm
