Factor 30-6v-18w30−6v−18w30, minus, 6, v, minus, 18, w to identify the equivalent expressions.
kompoz [17]

Answer:

Option C.

Step-by-step explanation:

The given expression is

30-6v-18w

We need to find the expression which is equivalent to the given expression.

The given expression can be rewritten as

6\times 5-6\times v-6\times 3w

The greatest common factor (G.C.F.) is 6. Taking out G.C.F., we get

30-6v-18w=6(5-v-3w)

Hence, the correct option is C.

Danny decided to invest his $500 tax refund rather than spending it. He found a bank that would pay him 4% interest, compounded
Blababa [14]
Present value, PV = $500
Future value, FV = 2*PV = 2*500 = $1,000
Rate, r = 4% = 0.04
Compounding times in a year, n = 4 (compounded quarterly)
Time, t = ??

The future value expression is stated as:
FV = PV (1+r/n)^nt

Substituting;
1000 = 500 (1+0.04/4)^4t
2 = (1.01)^4t
ln 2 = 4t ln 1.01
0.6931 = 4t* 0.00995
0.6931 = 0.0398t
t = 17.414 years

Time required for the amount to double is 17.41 years.
