Fiona cleans offices. She is allowed 5 seconds per square foot. She cleans building A, which is 3,000 square feet, and building B, which is 2,460 square feet. Will she finish these two buildings in an 8-hour shift?

Yes

Since the time taken t= 7.58 hours required to complete both buildings is less than the 8-hours shift then she can finish the two buildings.

Step-by-step explanation:

Given;

Building A = 3,000 square feet

Building B = 2,460 square feet

Total area of building A and B = 3,000+2460

= 5460 square feet

Rate = 5 seconds per square foot

Time taken to complete both buildings is;

Time t = Total area × rate per area.

t = 5460 × 5 seconds

t = 27300 seconds

t = 27300/60 minutes = 455 minutes

t = 455/60 hours

t = 7.583333333333 hours

t = 7.58 hours

Since the time taken t required to complete both buildings is less than the 8-hours shift then she can finish the two buildings.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
