Answer:
9 hours, 20 minutes
Step-by-step explanation:
When two ferries work together, they transport a day's cargo in 7 hours
The speed proportion or ratio of larger ferry to smaller ferry is given as 3 : 1
The sum of the ratio = 4 (3 + 1)
This means that it will take the smaller ferry = 7 x 4 hours to work alone = 28 hours, since the larger ferry is faster by 3.
Therefore, when larger ferry works alone, it will take it (7 x 4)/3 = 9.33 hours.
9.33 hours = 9 hours, 20 minutes.
Answer:
4.08 inches.
Step-by-step explanation:
A cube has six sides, and each of the sides has area of , where is the length of the edge of the cube.
Thus the total surface area of the cube is
Now we are told that this surface area is 100 square inches, therefore , and now we can solve for :
Answer:
5780
Let’s say her daughter is the 9 of the ratio. To find one part, you must divide 3060 by nine which gives you 340. That is one part. You can then multiply that by 8 to find the amount of money her son gets, which is 2720. Then you just add 3060+2720 which gives you 5780.
45°. I’m not sure what the relationship is but I think it’s linear pair ?
Answer:
d = 4de - 7
Step-by-step explanation:
7 - d = 4de - 2d
7 = 4de - 1d
7 - 4de = -1d
-7 + 4de = d
