4:6 4’7 4:7 because 4 is into the 15
To start, you want to determine the inequality. You can do this by setting the number of buying n fish to be less than or equal to her current amount of money, being as it can't go over or she wouldn't be able to afford the fish. This inequality would be written so her amount of money (20) would be greater than or equal to the cost of n fish (2.5n), which would then look as such: 20≥2.5n. To solve this inequality, just solve for n by dividing both sides by 2.5, giving you 8≥n. This would mean that Becky can afford to buy up to 8 fish.
According to my calculations,
A. is the correct answer.
8√5
Answer: g = 10
Step-by-step explanation: 8g + 3 = –6g + 13g + 13
8g + 3 = (–6g + 13g) + (13)
8g + 3 = 7g + 13
8g + 3 - 7g = 7g + 13 - 7g
g + 3 = 13
g + 3 - 3 = 13 - 3
g = 10
Answer:
7
Step-by-step explanation:
We need to first of all find the volume of the fish tank. The most probable shape the ship tank can have is that of a cuboid.
The volume of a cuboid is l * b * h
And this is equals 30cm * 70cm * 90cm = 189,000 cubic centimeters
The number of fish the tank can contain can be obtained by dividing the volume by the volume occupied by a single fish.
This is 189,000/27000 = 7
