The symbol √ means "square root of". √16 means "square root of 16".
It's a number that gives 16 when you multiply the number by itself.
There are <u>two</u> numbers that can both do the job. They are +4 and -4.
(+4) times (+4) = 16
(-4) times (-4) = 16
To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.
In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2
Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.
Answer choice C is the best option.
I hope this helps! :)
Answer:
$2000
Step-by-step explanation:
The amount of interest you pay (for simple interest) is the product of the original amount, the interest rate and the time in years. Let x be the original amount (how much money she borrowed):
720=x(0.09)(4)
720=0.36x
x=2000
