You and your family want to plan a beach trip to ocean lakes
Inga [223]

Answer:

Step-by-step explanation:

Im assuming that the cost of the house isn't per day, so it would be 6 days. I just added 60 to 1180 and counted how many times i added it. To check my work, you can just subtract 1180 from 1540, then divide by 60.

Sorry if this is wrong, but i tried my best. If its correct do you mind making me brainliest lol

Debora [2.8K]

Answer:

13.8 feet long.

Step-by-step explanation:

The end two pieces are 3.6 feet long.

The middle board must be 0.82 longer than the 3.6 feet.

The easy way to do this is to realize that the length of the middle part is 1.82 times the length of each of the end pieces.

1.82 * 3.6 = 6.552 feet long.

So the total length of the board must be

3.6 + 3.6 + 6.552 = 13.752 feet long. (That's a pretty long board).

Rounded it becomes 13.8 feet long.
