D. When you substitute for the variables the equation becomes -1-5×6=-31. First, you multiply -5 by 6 to get -30. This makes the equation -1-30=-31. -1-30 is -31 so your equation is now -31=-31.
The area of each triangular face is
.. A = (1/2)*b*h
.. Aside = (1/2)*(6 cm)*(5 cm) = 15 cm^2
The area of the triangular base is
.. Abase = ((√3)/4)*s^2 = (√3)/4*(6 cm)^2 = 9√3 cm^2
The total surface area is the base area plus the area of the three sides.
.. Atotal = Abase + 3*Aside
.. = 9√3 cm^2 +3*15 cm^2
.. = (45 +9√3) cm^2
.. ≈ 60.6 cm^2
Actually, there's an error in the picture. The height of the side should be 4, and the length of the edge should be 5. Making that adjustment, the total area is 51.6 cm^2.
It is hard to tell what is intended. Not all answers are showing, so we can't "reverse-engineer" the problem from the answers.
Answer:
its 7/6
Step-by-step explanation:
slope m = –4
equation
y - 3 = -4(x + 2)
y - 3 = -4x - 8
y = -4x - 5 where slope = -4 and y intercept = b = -5
Answer
Y intercept (0, -5)
This is how I do it :)
if it helps you any just translate 40% to .4 just do 40/100, there are two zeros in 100 so move the decimal of 40. over two places 40%=40/100=.4
130*.4=52 so therefore 52 is 40% of 130
