Answer:

30

Step-by-step explanation:

20% is 1/5 of 100.

This means working backwards we can multiply 6 and 5 because 1/5's reciprocal is 5.

This gets 30 gumballs.

Marie is purchasing a $108,000 home with a 30 year ortgage at 5.25%. What is her monthly principal and interest payment
schepotkina [342]

Answer:

Monthly interest rate is r=0,004375

Monthly principal c=590,625

Step-by-step explanation:

Monthly interest payment rate :

r=\frac{5.25}{12}:100=0,0004375

Now, we need to find monthly principal payment : c=\frac{rP}{1-(1+r)^{-N}}

Use this rule : N=30*12=360

P=108000

r=0,004375

c=\frac{0.004375*108000}{1-(1+0.004375)^{-360}} =\frac{472.5}{0.8}=590,625

ale4655 [162]

Answer:

1 / 9

Step-by-step explanation:

Given the number cube :

(11,12,11,12,20,20)

Spinner : (G, H, J)

Probability = required outcome / Total possible outcomes

P(20) = 2 / 6 = 1/3

P(H) = 1 / 3

P(20 and H) = P(20) * P(H) = 1/3 * 1/3 = 1 /9
