A response variable you are trying to measure once you've done the experiment.
What have you done? You've measured what sunglasses will do to affect eyesight. You have used a 10 week period to measure their response. You don't really care what the response is -- only if there is one.
10 people and 10 weeks don't change. Those two are not a choice for an answer. Now you come to the crunch of the question. Is it the sunglasses you are trying to measure or is it what your eyes have done because you were wearing sun glasses.
So we need an answer. If you say sun glasses, how did you measure what they did. THAT's the answer. The answer is not the sunglasses.
I got it! the Brass would cost $6 each and the Steel Parts would cost $3 each so if you were gonna buy 10 Brass and 13 Parts it would cost $60 for the brass and $39 for the Parts. So $60+$39= $99 And the answer is C
For a triangle it’s height times width.
For a square all you need is one sides length sense all the sides are the same. Then multiply it by itself!
Answer: it equals 1
Step-by-step explanation:
Area = length X width
A = L(12 ft) x W(9 ft) but since the cost of carpet is given in square yards not square feet we need to convert
A = (12 ft)(1 yd/3 ft) x (9 ft)(1 yd/3 ft) 1 yard = 3 feet so 1 foot = 1/3 yard
A = 4 yd x 3 yd divide by 3 ft which cancels the original ft and leaves yd's
A = 12 square yards
Cost = Area x price per yard
Cost = 12 sq yd X $35.00/ sq yd multiply and the sq yd's cancel leaving just cost in dollars
Cost = $420.00
