Claire wants to determine how brightly to illuminate her stage. stage width (in metres) x stage length (in metres) x 0.14 = total watts for stage

If her stage is 7.25 metros wide and 11.5 metres long,

a) calculate the exact number of watts needid to illuminate the stage
b) calculate the number of watts needid to illuminate the stage, rounded to the neares 10 watts,
c) write the answer to part a) in the form a x 10^k

Could you please check it and help me with corrections please please:
my answer is:
a)11.6725
b)
c) 1.16725x10^2

Thank you so much

a) is correct

b) you want to round off 11.6725 to the nearest 10 watts, so that would be 10 watts.
(11.6725 is closer to 10 than to 20)

c) no
it would be 1.16725 x 10^1

(you moved the decimal only 1 place)

You are so so nice, thank you so much:)))))You saved my love!!!!

To calculate the exact number of watts needed to illuminate the stage, we can use the given formula: stage width x stage length x 0.14. Let's plug in the values:

Stage width = 7.25 meters
Stage length = 11.5 meters

a) Calculate the exact number of watts needed:
Total watts = 7.25 meters x 11.5 meters x 0.14
Total watts = 93.6375 watts

So, the exact number of watts needed to illuminate the stage is 93.6375 watts.

b) To round the number of watts to the nearest 10, we look at the digit in the units place, which is 7. Since 7 is less than 5, we round down. Therefore, the number of watts needed, rounded to the nearest 10, is 90 watts.

c) To write the answer to part a) in the form a x 10^k, we need to express the number in scientific notation. The number 93.6375 can be represented as 9.36375 x 10^1.

So, the corrected answers are:
a) 93.6375 watts
b) 90 watts
c) 9.36375 x 10^1

Please note that in part b), the answer should be rounded down to the nearest 10, not up to the nearest 10 as mentioned in your response.
