Answer:
Step-by-step explanation:
If the exchange rate between British pounds (£) and US dollars ($) is £1 = $1.40, how much is £200 worth in dollars?
Include the $ sign in your answer.
280
$142.86
280.00
$280.00
$280
42.86
Subtracting 10x from the given equation gives
120 = 15x
Then dividing by 15 gives
8 = x
Zorah will have to play 8 hours in order to break even (cover her expenses exactly).
130ft: you would need to do 65.5 x 23 to get 1506.5 but this is in inches, not ft so you need to convert this, which means that you need to divide 1506.5 by 12 which gets 125.54..... and round that to the nearest tenth, which leaves you with 130ft
hope this helps
We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ). Answer: <span>C. sqrt( 2 )</span>
