Whoops, didn't read that right. It is 25. Thought it was 4*n=4.
Q + d = 63....q = 63 - d
0.25q + 0.10d = 10.80
0.25(63 - d) + 0.10d = 10.80
15.75 - 0.25d + 0.10d = 10.80
-0.25d + 0.10d = 10.80 - 15.75
-0.15d = -4.95
d = -4.95/-0.15
d = 33 <=== 33 dimes
q + d = 63
q + 33 = 63
q = 63 - 33
q = 30 <=== 30 quarters
Answer:
1.21 * 10^25.
Step-by-step explanation:
11 *10^11 * 12 * 10^2
= 11*12 * 10^11 * 10^12
= 121 * 10^(11+12)
= 121 * 10^23
= 1.21 * 10^25.
Note: True Scientific notation is N * 10^n where 1 ≤ N < 10.
Answer:
5
Step-by-step explanation:
Divide each side by 8 or do 40 divided by 8.
Hope this helps! Have a great day!
So, 14 sentences per minute = 840 sentences per hour (60 minutes in an hour, 14(60)=840)
If 17 pages have 120 sentences on each page, we can conclude that there are a total of 2040 sentences that remain (17x120=2040)
If Jolie can read 840 sentences per hour, we can divide 2040/840 (total # of sentences left divided by sentences per hour)
2040/840 = 2.43 hours.
