Answer: ~73.89% of students at school are not freshmen
Step-by-step explanation:
To find a percentage, you need to divide the partial group by the large group. For example, if I have 2 bananas, and 10 fruits, what percentage of bananas do I have? The correct answer would be (2 bananas ÷ 10 fruits), which equals 20% (the equation equals 1/5, or 0.2, but when finding percentages, you multiply the final answer by 100 and add the % sign.).
Now, you have 223 freshmen and 854 students. To calculate the percentage of students at the school other than freshman, you need to find out how many students aren't freshman. Do this by finding the difference of the amount of students in the school and the amount of freshmen.
> 854 - 223 = 631 students that are not freshmen
Use this number to find out the percentage of students that are not freshmen.
> 631 non-freshmen ÷ 854 total students ≈ 73.89%
Well lets do the math
220 x 8 = 1760
1240 x 2 = 2480
2480 + 1760 = 4240
So we need 2 first class and 8 coach.
You need the number of miles per kilometer, or vice versa.
Answer:
0.72
Step-by-step explanation:
1000ml in a litre. 12 x 60 ( minutes in an hour) = 720.
720/1000=0.72
Answer:
The two figures are similar and hey are not solid.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Leah claims that these figures are not similar. When she compared the heights, she wrote 2/7. Then she compared the bases and 21/6. Why is Leah having trouble? Explain completely</em>
(Please have a look at the attached photo)
My answer:
In the first ratio, she compared the small figure's height to the large figure's height that is: 2/7
In the second ratio, she compared the large figure's base to the small figure's base that is: 21/6
=> She is wrong in this step, the ratio must be 6/21
Hence she needs to compare bases and heights thorugh division because the ratio between heights and the ratio between bases must be equal
The scales are equal
=> Therefore, those rectangles are congruent.
