What amount of money do you have if you have 5 pennies, 13 nickels, 14 dimes, 2 quarters, and one 5 dollar bill?

BartSMP [9]

Answer:

$7.60

Step-by-step explanation:

Penny = $0.01
Nickel = $0.05
Dime = $0.10
Quarter = $0.25

( 5 × 0.01 ) + ( 13 × 0.05 ) + ( 14 × 0.10 ) + ( 2 × 0.25 ) + 5

-The 5 at the end represents the one five dollar bill.

Simplified: (solve what is in the parenthesis)

0.05 + 0.65 + 1.4 + 0.50 + 5 = $7.60

For what values of K does x2+kx+9=0

Airida [17]

Answer:

$k = 6$

Step-by-step explanation:

$x {}^{2} + kx + 9 = 0$

here,

a = 1,

b = k

c = 9

now,

$D = b {}^{2} - 4ac$

$k {}^{2} - 4(1)(9) = 0 \\ k {}^{2} - 36 = 0 \\ k {}^{2} = 36 \\ k = 6$
