Which choices are equivalent to the expression below? Check all that apply.
luda_lava [24]

3\sqrt{6} = \sqrt{9}*\sqrt{6} = \sqrt{9*6} = \sqrt{54}

The rule I'm using is

\sqrt{x}*\sqrt{y} = \sqrt{x*y}

note how I rewrote "3" into the square root of 9, so that everything would have a square root over it, and that allows me to use that rule above.

n200080 [17]

Answer:

The answer to your question is: 320

Step-by-step explanation:

Data

1/4 of the calories in a chocolate - 10 = calories in an apple

Equation

    Calories in a chocolate bar = 4(calories in apple + ten)

                                                                    = 4(70 + 10)

                                                                    = 4(80)

                                                                   = 320

Answer:

Your answer is not there.... but my answer is... so, check it put...

Step-by-step explanation:

P is the principal amount, $400.00.

r is the interest rate, 7.5% per year, or in decimal form, 7.5/100=0.075.

t is the time involved, 6 month period(s) time periods.

To find the simple interest, we multiply 400 × 0.075 × 3 to get that:

The interest is: $90.00
