Answer:
in tank A, we need 1 gram of food per fish.
In tank B, we need 2 gramms of food per fish.
If Na is the number of fish in tank A and Nb is the number of fish in tank B.
Then, the amount of food that the tank A needs is:
Na*1g of food
The tank B needs:
Nb*2g of food
And we know that Nb = 2/3*Na
we can replace it and get:
2/3*Na*2g
Then if both tanks need the same amount of food, we should have that both of these equations are equal:
food of tank A = food of tank B
Na*1g = (2/3)*Na*2g
we solve this for Na
Na = (2/3)*Na*2g/1g = (2/3)*Na*2 = (4/3)*Na
Na = (4/3)*Na
This equation has no solution, and from here we can conclude that if Nb = 2/3*Na, she will never give the same amount of food to both tanks.
b) knowing that the amount of food neded in tank A is half the amount for tank B, then we need the doulbe of fish in the tank A than in the tank B
Na = 2*Nb
Lisa cannot feed both tanks the same amount of food under the given conditions. If Tank A has 'a' smaller fish and Tank B has 2/3 of the number of fish in Tank A, then Tank A would require 'a' grams of food while Tank B would require 4/3 'a' grams, which are not the same.
The student is asking whether Lisa can ever feed the same amount of food to both Tank A and Tank B, given that the larger fish in Tank B eat 2 grams of food per day and there are 2/3 the number of fish in Tank B compared to Tank A, which contains smaller fish that eat 1 gram of food per day. To determine if there is a scenario where Lisa can feed both tanks the same amount of food, we will need to set up an algebraic equation.
Step-by-step calculation:
Let the number of smaller fish in Tank A be represented by the variable a.The number of larger fish in Tank B would then be 2/3a as Tank B contains 2/3 the number of fish that Tank A contains.Calculate the total food for Tank A: a fish × 1 gram/fish = grams.Calculate the total food for Tank B: 2/3a fish × 2 grams/fish = 4/3a grams.Set the total food for both tanks equal to each other to find the condition when Lisa feeds the same amount to both tanks: a = 4/3a.Solve for a: This equation has no solution because Tank A cannot contain the same number of grams of food as 4/3 times itself.Therefore, Lisa can never feed both tanks the same amount of food unless one of the conditions changes, like the amount of food fed to the fish or the ratio of fish between the tanks.

What is 62.5% as a fraction in simplest form
Answer:
5/8
Step-by-step explanation:
The required simplest form of 62.5% is 5/8.
Given that 62.5%.
To express a% as a fraction in simplest form, we divide a% by 100 gives,
a% = a/ 100
For example, if a = 75%, gives:
75% = 75/ 100
Simplifying the fraction:
75 / 100
To further simplify, divide both the numerator and denominator by their greatest common divisor (GCD), which is 25:
75 ÷ 25 / 100 ÷ 25
This gives:
3/4
Thus, 75% as a fraction in simplest form is 3/4.
Consider the example of 62.5%.
To express 62.5% as a fraction, divide 62.5% by 100:
62.5% / 100
Simplifying the fraction:
62.5 / 100
To further simplify, divide both the numerator and denominator by their greatest common divisor (GCD), which is 12.5:
62.5 ÷ 12.5 / 100 ÷ 12.5
This gives:
5/8
Therefore, 62.5% as a fraction in simplest form is 5/8.

If you are asked to find 621 / 59 how do you know the quotient will be greater than 10 before you actually divide?
Final answer:
You can estimate that the quotient of 621 / 59 is greater than 10 by rounding 59 to 60 and recognizing that 600 divided by 60 equals 10, and then considering that 621 is slightly more than 600 while 59 is slightly less than 60.
Explanation:
To determine if the quotient of 621 / 59 will be greater than 10 before actually dividing, you can estimate using numbers that are easier to work with. The number 59 is close to 60, which is a multiple of 10. If you round 59 up to 60, you can easily see that 600 (10 times 60) would be divided cleanly into 10 parts.
Thus, you can infer that since 621 is slightly higher than 600, and 59 is slightly less than 60, the quotient must be slightly greater than 10.

Last week, Chen bought 8 1/2 gallons of gas at $2.30 per gallon. This week, he bought 4 3/10 gallons of gas at $2.70 per gallon.
What was his total cost?
The total cost of the gallons of gas will be $31.16
Since Chen bought 8 1/2 gallons of gas at $2.30 per gallon, the cost will be:
= 8 1/2 × $2.30
= 8.5 × $2.30
= $19.55
Since he also bought 4 3/10 gallons of gas at $2.70 per gallon, the cost will be:
= 4 3/10 × $2.70
= 4.3 × $2.70
= $11.61
Therefore, the total cost will be the addition of both values gotten and this will be:
= $19.55 + $11.61
= $31.16
Therefore, the total cost is $31.16

I will put best answer for the first person to answer.
Final answer:
The area of the top of the triangular pizza plate is calculated using the formula for the area of a triangle (½ × base × height), which results in an area of 40 inches squared.
Explanation:
As we know that:
The area of a triangle can be calculated using the formula:
Area = ½ × base × height.
In this case, the triangular plate has a base of 5 inches and a height of 16 inches. Substituting these values into the formula gives:
Area = ½ × 5 inches × 16 inches = ½ × 80 inches2 = 40 inches2.
Therefore, the area of the top of the plate is 40 inches squared.

Dreanne uploads 292 pictures to her online album.Her online album shows 12 pictures on each page.How many pages does she scroll through to see all 292 pictures?What does the remainder represent
Dreanne needs to scroll through 25 pages to see all her 292 pictures. She scrolls through 24 full pages, and the 25th page has the remaining 4 pictures.
Explanation:To find out how many pages Dreanne has to scroll through to see all 292 pictures in her online album, we need to divide the total number of pictures by the number of pictures per page. We know there are 292 pictures and each page shows 12 pictures.
Dividing 292 by 12, we get:
292 ÷ 12 = 24 R 4
This means Dreanne will have to scroll through 24 full pages of pictures. However, there's a remainder of 4, which means there will be an additional page with only 4 pictures on it. In total, Dreanne will scroll through 25 pages. The remainder represents the number of pictures on the last, non-full page.
