The lateral area is the area of everything but the base. A shortcut formula for this area is Ph. (where P is the perimeter of the base and h is the height of the prism).
So the lateral area is (3+9+9.49)x37 = 795.13 m^2 or 795 m^2
The surface area is the lateral area plus the area of the 2 bases. The base is a triangle. (area = 1/2 bh)
Since there are two identical bases, the total area of the base is just 3x9 = 27
So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.
Answer: p>−4
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2−7p<26
Step 1: Simplify both sides of the inequality.
−7p−2<26
Step 2: Add 2 to both sides.
−7p−2+2<26+2
−7p<28
Step 3: Divide both sides by -7.
−7p
−7

p>−4
Answer:
He has to score 84 %
Step-by-step explanation:
64 + 64 + 64 + 64 = 256
5*68 = 340
340 - 256 = 84
(64 + 64 + 64 + 64 + 84)/ 5 = 68
Twenty is 40% of 50 because 10% of 50 is 5 so 5*4 = 20
