The circle graph shows the various percentages of a total of 400 students surveyed.
Those that favored visiting Florida were 38% of the total. Therefore, we have
If 152 of the total 400 students favored visiting Florida, that means the others all put together were 248 students. This means there was 96 more surveyed than those who favored visiting Florida.
Those who favored visiting Florida = 152 surveyed
Those who favored visiting others = 248 surveyed
How many more than favor visiting Florida = 248 - 152
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.
