Answer:

3.75 feet.

Step-by-step explanation:

Given:

The volume of a right octagonal prism is 30 cubic feet.

The area of the octagonal base is 8 square feet.

Question asked:

What is the height of the prism ?

Solution:

As we know:

 $Volume\ of \ octagonal-prism=base\ area\times height$

$30=8\times height\\ \\ By\ dividing\ both\ sides \ by\ 8\\ \\ \frac{30}{8} =\frac{8}{8} \times height\\ \\ 3.75=height$

Therefore, height of the prism is 3.75 feet.

Vikki [24]

Answer:

a) $432

b) (i) $8970

Step-by-step explanation:

Given that:

Ratio of Cost of Hansi and Megan is 7 : 4.

Hansi's holidays cost = $756

Hansi's earnings in 2008 = $7800

In 2009, there are 15% more earnings than in 2008.

To find:

Cost of Megan's holiday.

Earnings in 2009 ?

Solution:

As per given question statement,

Let the holiday cost of Hansi = 7 $x$

Let the holiday cost of Megan = 4 $x$

As per question statement:

$7x=756\\\Rightarrow x = \$108$

We have to find the value of 4 $x$ now.

$4x = 4\times 108 = \bold{\$432}$

b)(i)

Earnings in 2009:

$7800 + 15% of $7800

$\Rightarrow 7800 +\dfrac{15}{100}\times 7800\\\Rightarrow 7800 + 1170\\\Rightarrow \$8970$
