Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.
AURORKA [14]

Answer:

The answer is A. 755 m2; 815 m2

Step-by-step explanation:

The answer is A) 472m^2; 486 m^2.

Let a, b, and c be the sides of the base and h be the height of the prism

a = 2 m

b = 7 m

c = 7.28 m

h = 29 m

The lateral surface area is:

LA = a*h + b*h + c*h = h * (a + b + c)

LA = 29 * (2 + 7 + 7.28) = 29 * 16.28 ≈ 472 m²

The surface area is:

SA = LA + 2 * 1/2 * a * b

SA = 472 + 2 * 7 = 472 + 14 = 486 m²

Use the simplest rule you can find to calculate the next three terms of the following sequence. 8, 3, 0, –1, 0, . . . a. 0, 0, 0

Rule: second differences are 2.

Selection C is appropriate.

_____
First differences are the sequence of differences of the given numbers:
.. 3 -8 = -5
.. 0 -3 = -3
.. -1 -0 = -1
.. 0 -(-1) = 1
Second differences are the sequence of differences of these:
.. -3 -(-5) = 2
.. -1 -(-3) = 2
.. 1 -(-1) = 2
All of these are 2, so the sequence can be described by a *second* order polynomial (because *second* differences are a non-zero constant).

Charles is camping. His campsite is 7/8 miles away. He walks at a speed of 1 7/8 miles per hour. How many minutes will it take h
eduard

Answer

28 minutes or 7/15 of an hour

Step-by-step explanation:

We know that Rate*Time = Distance. Because we are given distance and rate, we can easily change the equation to Distance/Rate = Time.

7/8 / 1 7/8 =

7/8 / 15/8 =

7/8 * 8/15 =

7/15 hour

7/15 * 60 = 28 minutes
