I believe the answer is B
Answer:
9.7 %
Step-by-step explanation:
Step 1
The formula for Percentage increase = increase/Original Amount × 100
Increase = Current amount - Original Amount
= 5 feet 8 inches - 5 feet 2 inches
= 6 inches
Increase = 6 inches
Step. 2
Before calculating Percentage increase, convert original amount to inches for easy calculation
Hence:
Original amount = 5 feet 2 inches
1 foot = 12 inches
5 feet = x
Cross Multiply
x = 5 × 12 inches = 60 inches
Original amount = 60 inches + 2 inches = 62 inches
Percentage increase
= 6 inches/62 inches × 100
= 9.6774193548%
Approximately = 9.7 %
The percent increase in her height = 9.7%
What we know: 35 minutes per rollercoaster, 25 minutes per show, 3 more coaster
1 show
1 show (25 minutes) (+3 more rollercoasters than shows), 4 coasters (35x4) 140 minutes = 165 minutes total. ..... too small
2 shows (50 minutes) (+3 more rollercoasters than shows), 5 coasters (35x5) (175 minutes) = 225 minutes total ....... too small
3 shows (75 minutes) (+ 3 more rollercoasters than shows), 6 coasters (35x6) (210) = 285 minutes total ....... too small
4 shows (100 minutes) (+3 more rollercoasters than shows), 7 coasters (35X7) (245) = 345 minutes total ........ answer.
Answer: 7 rollarcoasters, 3 shows, 345 minutes total
Answer:
330
Step-by-step explanation:
Because he runs 6 yards in 1 minute so if we multiply 55 x 6 we get 330.
To solve that question we can think by the following way:
- The first letter can be any of the letters (A, C, T or G). Therefore there are 4 possibilites.
- To choose the second letter of the sequence, any letter also can be chose. So, one more time, there are 4 possibilites.
Using the fundamental principle of counting, we will find out that can be formed differents sequences (for example, AA, AG, TT, TG, CT...).
Know we know that, we can generalize. If I have elements and I must choose one of them times to do a sequence, the total number of sequence that I can form will be .
In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is (29 times) .
Therefore, there are DNA sequences with exactly 29 letters long.
