9.8x=39 1/5
x=4
Answer:
56 cm^2
Step-by-step explanation:
Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.
Area of square base (side^2)
4^2 = 16 cm^2
Area of ONE triangular face (1/2 x b x h):
1/2 x 4 x 5 = 10 cm^2
Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2
ADD all the areas of triangles and square:
16 cm^2 + 40 cm^2 = 56 cm^2
HOPE THIS HELPS
Have a nice day!
Answer:
y=68
Step-by-step explanation:
Answer: (2.75-2.40)/(2.75) * 100 [Before rounding to the nearest tenth]
Step-by-step explanation:
Formula for percentage decrease = (old-new)/(old) * 100
so substituting in, you get (2.75-2.40)/(2.75) * 100
From here, you can just plug this into a calculator (don't have on me rn)
