248.95 square centimetres

Step-by-step explanation:

The surface area of a 3D figure is the sum of the areas of the exterior surfaces.

Here, we have one equilateral triangle as the base with base 13 and height 11.3. We also have three other congruent lateral triangles with base 13 and height 9.

The area of a triangle is denoted by A = (1/2) * bh, where b is the base and h is the height.

The area of the base triangle is:

A = (1/2) * bh

A = (1/2) * 13 * 11.3 = 73.45 cm²

The area of one lateral triangle is:

A = (1/2) * bh

A = (1/2) * 13 * 9 = 58.5 cm²

Since there are 3 such triangles, multiply 58.5 by 3:

58.5 * 3 = 175.5 cm²

Finally, add 175.5 to 73.45:

175.5 + 73.45 = 248.95 cm²

The answer is thus 248.95 square centimetres.

the homeowners insurance cost for a 115,000 wood frame house is 80,500.

step-by-step explanation:

it is given that the coverage rate for wood frame house is 0.7.

the value of wood frame house is 115,000.

.

homeowners insurance cost for a 115,000 wood frame house is

therefore the homeowners insurance cost for a 115,000 wood frame house is 80,500.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
