Answer:
11. It will take about 26 minutes to install a singular tile.
12. It will take about 10 more minutes to install a light than it does to install a cable.
Step-by-step explanation:
11. Since installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time, you can divide the total amount of time by the number of tiles.
390/15= 26 minutes
It will take about 26 minutes to install a single tile.
12. By looking at the chart it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.
22-12= 10 minutes
It takes about 10 minutes longer to install a light than it does a cable.
Answer:
You end up getting the same equation!
Step-by-step explanation:
check the picture below.
the line QS is just a flat-line and therefore it has 180° on either side, so the angle QPR is 57°, as you see there, and since we know the diameter is 20, that simply means the radius of the circle is 10.

Answer: 2008
Step-by-step explanation:
Given : The gross federal debt y (in trillions of dollars) for a certain country in year x is approximated by the equation 
, where x is the number of years after 2000.
To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get
The required year will be = 2000+8=2008.
Hence, in 2008 the federal debt will be $10.68 trillion.
