A total of $10,000 is invested in two funds, Fund A and Fund B. Fund A pays 5% annual interest and Fund B pays 7% annual interes
RoseWind [281]

Answer:

The amount put in the account that paid 7% ( Fund B) was $6,500

Step-by-step explanation:

Let

x -----> the amount put in the account that paid 5% (Fund A)

$10,000-x -----> the amount put in the account that paid 7% (Fund B)

in this problem we have

5\%=5/100=0.05

7\%=7/100=0.07

so

630=x(0.05)+(10,000-x)0.07

630=0.05x+700-0.07x

0.07x-0.05x=700-630

0.02x=70

x=\$3,500

\$10,000-x=\$6,500

therefore

The amount put in the account that paid 7% ( Fund B) was $6,500

rewona [7]

Answer:

41 sqrt(3)

Step-by-step explanation:

7 sqrt(27) + 5 sqrt(48)

7 sqrt(9*3) + 5 sqrt(16*3)

We know that sqrt(ab) = sqrt(a) * sqrt(b)

7 sqrt(9)sqrt(3) + 5sqrt(16) sqrt(3)

7 * 3 sqrt(3) + 5 *4 sqrt(3)

21 sqrt(3) + 20 sqrt(3)

41 sqrt(3)
