Answer:
b)
{t | –3 < t ≤ 5}
Step-by-step explanation:
–4 < 3t + 5 ≤ 20
⇔
-4 - 5 < 3t ≤ 15
⇔
-9 < 3t ≤ 15
⇔
-3 < t ≤ 5
Answer:
To find the value of this expression you need to add and subtract from left to right
74.9+5.23-81.4-16 (add the first two, first)
80.13-81.4-16 (74.9+5.23=80.13) (next subtract the next two)
-1.27-16 (80.13-81.4=-1.27) (Last subtract the last two)
-17.27 (-1.27-16=-17.27)
-17.27
Hope this helps ;)
Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
Timothy scored 83 out of 100.
His percentile rank in his class = 72
Clayton scored 85 out of 100.
His percentile rank in his class = 70.
Since Clayton's percentile rank is lower than Timothy's rank.
So, Timothy performed better with respect to the rest of the students in the class.
Hence, Timothy as his percentile score is higher.
Therefore, Fourth option is correct.
12 hours..........
+ - = 1
Multiply by 12 to clear the fractions
3t + 2t - 4t = 12
t = 12 hrs to fill the pool
The prime factorization of 5005 is 5*7*11*13
You have to order the digits in increasing order: 1 1 1 3 5 7.
The code is 1 1 1 3 5 7
