Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches
area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches
Answer:
b = -36
Step-by-step explanation:
Start by distributing both th 5 and the negative 1 into their corresponding parentheses.
((5*2b)-(5*3)) > (10b - 15)
((-1*11b)+(-1*1)) > (-11b - 1)
so you have:
10b - 15 - 11b - 1 = 20
Next you would Combine like terms to get:
-b - 16 = 20
Add the 16 to both sides
-b = 36
and divide each side by -1
b = - 36
hope this helps
Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
12/100 = 6/50
6/50 = 3/25
Simplified: 3/25
