What is the surface area of a square pyramid with a base perimeter of 60 inches is and a slant height of 13 inches
pentagon [3]

Answer:

615 in^2

Step-by-step explanation:

The base of each triangle is 60/4 = 15 in. and the height of each triangle is 13 in.  One triangle = .5bh = .5(15)(13) = 97.5.  The lateral area = 4(97.5) = 390.  The area of the square base is 15(15) = 225.  The total area = 390 + 225 = 615 sq. in.

B7<br> __<br> b6<br><br> Multiply or divide as indicated.
dimulka [17.4K]

For this case we have the following expression:

\frac {b ^ 7} {b ^ 6}

By definition of division of powers of the same base, we have to place the same base and subtract the exponents, that is:

\frac {a ^ m} {a ^ n} = a ^ {n-m}

So:

\frac {b ^ 7} {b ^ 6} = b ^ {7-6} = b ^ 1 = b

Answer:

b
