Answer:
lower bound: 315 litres
upper bound: 324 litres
Step-by-step explanation:
The following rules apply:
- if the last digit of the number is 1, 2, 3, or 4; it is rounded down
- if the last digit of the number is 5, 6, 7, 8, or 9.
; it is rounded up
So:
314 is rounded to 310
315 is rounded to 320
324 is rounded to 320
325 is rounded to 330
C I thinkkkkkkkkkkk!!!!!!!!!
The error Soro makes while solving inequality is that "Soro should have reversed the inequality symbol when using the division property of inequality".
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The inequality is given as 50-2.5x≥20, now solving the inequality,
Divide both sides of the inequality by -2.5x, therefore, reverse the inequality symbol when using the division property of inequality.
Hence, the error Soro makes when writing or solving inequality 50-2.5x≥20, is that "Soro should have reversed the inequality symbol when using the division property of inequality".

Answer:
60%
Step-by-step explanation:
To find the total pass = 65 * number of student that passed, let it be be represented by P and number of students that failed F
Total pass = 65p
And total fail = 35F
For the total pass and failure will be 53(P+F)
Equating to total pass and total fail
65P +35F = 53( P+ F)
65P+35F = 53P+ 53F
65P-53P =53F-35F
12P=18F
2P= 3F
Hence there are 3 passing scores for every 2 failure scores, hence there are a multiple of 5 scores and the same multiple of 3 passing scores.
3/5 * 100= 60%
