Fittoniya [83]

Answer:

Mr. Chang will have 15714.90 dollars.

Step-by-step explanation:

p = 650

r = $7.8/4/100=0.0195$

Number of periods or n = $5\times4=20$

Future value formula is : $p[\frac{(1+r)^{n}-1}{r} ]$

Putting the values in formula we get;

$650[\frac{(1+0.0195)^{20}-1}{0.0195} ]$

= $15714.90

Hence, Mr. Chang will have 15714.90 dollars.

A swimming pool is a shape of a right rectangular prism if the pool is 12 3/4 yards long 5 2/3 yards wide and 9 yards deep what

Artemon [7]

Answer:

$V=650.25\ yards^3$

Step-by-step explanation:

Given that,

Length = $12\dfrac{3}{4}\ yards$

Width = $5\dfrac{2}{3}\ yards$

Depth = 9 yards

We need to find the volume of the swimming pool. The formula for the volume of a cuboid shape is given by :

$V=lbh\\\\V=12\dfrac{3}{4}\times 5\dfrac{2}{3}\times 9\\\\=\dfrac{51}{4}\times \dfrac{17}{3}\times 9\\\\V=650.25\ yards^3$

So, the volume of the swimming pool is equal to $650.25\ yards^3$ .
