749 is divisible by 7 and 107, so that's out. 299 is a product of 13 and 23, so that ones also out. And 989 is divisible by 23 and 43. Which leaves 1009, divisible only by 1 and 1009 :)

Simplify the cube root in simplest radical form.<br> 9x374<br> Please help
algol [13]

Answer:

D. xy\sqrt[3]{9y}

Step-by-step explanation:

\sqrt[3]{9x^3y^4}

\sqrt[3]{9}\sqrt[3]{x^3}\sqrt[3]{y^4}

The \sqrt[3]{x^3} cancels out to become x:

\sqrt[3]{9}x\sqrt[3]{y^4}

Split the y^4=y*y^3

\sqrt[3]{9}x\sqrt[3]{y^3}\sqrt[3]{y^1}

\sqrt[3]{y^3} =y

xy\sqrt[3]{9} \sqrt[3]{y}

Put the cube root of y and cube root of 9 together:

xy\sqrt[3]{9y}

terry opened a savings account in December with $132 and saved $27 each month beginning in January the value of terrys account i
liq [111]
Let S be the amount in a savings account. 
Let m be the number of months.

General equation
S = 132 + 27m

Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321

Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.

16/9(1.2b)=4.8(20/3)<br> solve
mart [117]

\frac{16}{9}(1.2b)=4.8( \frac{20}{3})

Multiply 4.8 into (20/3), and multiply 16/9 with (1.2b)

\frac{19.2b}{9} = \frac{96}{3}

\frac{19.2b}{9} = 32  Multiply 9 on both sides

19.2b = 32(9)

19.2b = 288          Divide 19.2 on both sides

b = 15
