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.

LekaFEV [45]

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.

Step 2: Add 2 to both sides.

−7p−2+2<26+2

−7p<28

Step 3: Divide both sides by -7.

−7p

−7

Adrian's mean score for four tests is 64%. He wants to increase his mean to 68% after the fifth test. What does he need to score
FrozenT [24]

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
