Lubov Fominskaja [6]

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Let

the breadth =x

the length =6x

$\sf Area=160yard^2$

As we know that in a rectangle

${\boxed{\sf Area=lb}}$

Substitute the values

${:}\longrightarrow$ $\sf x\times 6x=160$

${:}\longrightarrow$ $\sf 6x^2=160$

${:}\longrightarrow$ $\sf x^2={\dfrac {160}{6}}$

${:}\longrightarrow$ $\sf x^2=26.6$

${:}\longrightarrow$ $\sf x=\sqrt {26.6}$

${:}\longrightarrow$ $\sf x=5.1yards$

Length=6\times 5.1=30.6yards
Breadth=5.1yards

Whats the total cost of an item that sells for $17.00, if the sales tax rate is 7%

Rainbow [258]

The total cost for this item is $18.19.
To find the sales tax of something, you move the decimal two places to the left on the percent. Then you multiply the items cost and the tax together, which gets you $1.19. Add the original amount with 1.19 and you get 18.19.
