Distance varies directly as time. If John can travel 400 miles in 8 hours, What would be the direct variation equation to represent this (hint: y = kx)? How far will he travel in 12 hours?

600 miles

Step-by-step explanation:

4800 = 8x

x = 600 miles

equation to represent this:

   miles:  x

   hours:  y

   400y = 8x

you can use a^2+ b^2=c^2

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
