If you have 2 of the same factor in a square root you take them out but just write one.

Looking at \sqrt{363}
\sqrt{363} = \sqrt{3*11*11} =11 \sqrt{3}

Looking at 3 \sqrt{27}
3\sqrt{27}=3 \sqrt{3*3*3}  = (3*3)\sqrt{3} =9 \sqrt{3}

Put them back together:
11 \sqrt{3} -9 \sqrt{3} =2 \sqrt{3}

Jose received $250 for his birthday from his family. He wishes to buy a motorcycle and decides to use his birthday money towards
BartSMP [9]

Answer:

He will have $276.10 available towards the down payment for his motorcycle

Step-by-step explanation:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

P = 250, t = 2, r = 0.05

Compounded quarterly, so n = 12/4 = 3.

We have to find A.

A = P(1 + \frac{r}{n})^{nt}

A = 250(1 + \frac{0.05}{3})^{3*2}

A = 276.1

He will have $276.10 available towards the down payment for his motorcycle

Explain how knowing that 5/8= 0.625 heps you write the decimal for 4 5/8
netineya [11]
To convert a fraction to a decimal , the solution is to divide the numerator by the denominator. Since its a mixed fraction, you already know what  the 5/8 of the problem is (0.625). All you do it add the 4 to the decimal and it'll be 4.0625
