Emma is going camping. each side triangle on her tent is 5 feet tall the square base is 4 feet wide what is the surface area of her tent?

The surface area of her tent = 36.661 ft²

Step-by-step explanation:

∵ The tent is shaped square pyramid without base

∴ The tent has 4 triangular faces

∴ Its surface area = area of each triangular face × 4

∵ The triangular face has base of length 4ft and 2 equal sides of

   length 5ft

∴ The height of the Δ =

∴ Its surface area = 4 × = 36.661 ft²

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
