Answer:

n = 5

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} = a^{(m+n)} ,

(a^m)^{n} = a^{mn}

Given

(3^{n}.3^{2} ) ^{4} = 3^{28} , then

(3^{(n+2)}) ^{4} = 3^{28}

3^{4(n+2)} = 3^{28}

Since the bases on both sides are equal, both 3 then equate the exponents

4(n + 2) = 28 ← divide both sides by 4

n + 2 = 7 ( subtract 2 from both sides )

n = 5

Explain how Cavalieri’s principle can be used to find the volume of any solid.
Kruka [31]

Answer:

Cavalier's principle can be used to find the volume of any solid.

Step-by-step explanation:

Cavalier's Principle:

  • Cavalier introduced parallel planes and area to describe the relationship between solids.
  • Cavalier stated if two solids have the same height and equal areas of the base everywhere along the height then the solids have the same volume.
  • Suppose two regions are included between two parallel planes.
  • If every plane parallel to these two planes intersects both regions in cross-sections of equal area, then the two regions have equal volumes.
  • The formula for the volume of a prism is the area of the base times the height.

A school cafeteria uses 10
gladu [14]

Using proportions, it is found that there are 5 cups of milk in each bowl of chocolate pudding.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The cafeteria used 10 quarts for 8 bowls, hence the number of quarts per bowl is:

10/8 = 1.25

Each quart has 4 cups, hence the number of cups is:

4 x 1.25 = 5 cups.
