if there is a total of 56 fish in the tank,than 24 of the fish are orange
The number of orange fish is 1 1/3 times the number of blue fish.
If there are 12 blue fish in the tank, then there are 18 orange fish.
Answer:
b) The number of orange fish is 1 1/3 times the number of blue fish.
Step-by-step explanation:
We are given the following information in the question:
In a fish tank, the ratio of orange fish to blue fish is 4:3.
Thus, we can write:
Thus, total number of fishes in the tank can be written as:
a) False
If there is a total of 56 fish in the tank,than 32 of the fish are orange
Total number of fish = 56
b)True
c) False
If there are 12 blue fish in the tank, then there are 16 orange fish.
Number of blue fish = 12
Answer:
The longest side length is 31.764705882352941
Step-by-step explanation:
Add up all the sides and then make it equal to 102
To get perimeter you add up all the sides
(12a) + (6a + 8) + (6a + 8) + (10a - 4) = 102
(18a +8) + (16a + 4) = 102
34a + 12 = 102
- 12 - 12
34a = 90
a = 2.647058823529412
Then plug in a to 12a to get the longest side length
12(2.647058823529412) = 31.764705882352941
Answer: 2/5
Step-by-step explanation:
At Lincoln High School, 1/2 of the students play an instrument. This means that if we had 10 students, 5 of them would play an instrument.
Of the students who play an instrument, 1/2 play a string instrument. This means that out of those 5 students who play an instrument, 1/2 of them play a string instrument.
To find out how many students play a string instrument, we can calculate 1/2 of 5.
1/2 of 5 is equal to 2.5. However, since we're dealing with whole students, we can't have half a student. So, we round down to the nearest whole number, which is 2.
Therefore, 2 out of the 5 students who play an instrument at Lincoln High School play a string instrument.
In terms of fractions, this can be expressed as 2/5. So, 2/5 of the students at Lincoln High School play a string instrument.
