Find the product of 30−−√ and 610−−√. Express it in standard form (i.E., ab√).

Zina [86]

we are given

$\sqrt{30} *\sqrt{610}$

we can radical formula

$\sqrt{a} *\sqrt{b}=\sqrt{a*b}$

we get

$\sqrt{30} *\sqrt{610}=\sqrt{30*610}$

$\sqrt{30} *\sqrt{610}=\sqrt{3*61*100}$

we can also write as

$\sqrt{30} *\sqrt{610}=\sqrt{100}*\sqrt{3*61}$

$\sqrt{30} *\sqrt{610}=10\sqrt{183}$ ............Answer

the interest earned on an account varies directly with the balance in the account. if an account with a balance of $200 earns $1

liq [111]

Answer:

$\$31.25$

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

y-------> the interest earned on an account

x------> the balance in the account

step 1

Find the constant k of proportionality

For $x=\$200,y=\$12.50$

$k=y/x$

substitute the values

$k=12.50/200=0.0625$

The equation is

$y=0.0625x$

step 2

Find the amount of interest earned on an account with a balance of $500

For $x=\$500$ substitute in the equation and solve for y

$y=0.0625(500)=\$31.25$
