200/5 = 40 mph 200/4 = 50 mph Let x be the speed in still waters and y the speed of current. x + y = 50 x - y = 40 ADD 2x = 90 x = 45 mph ANSWER is C) 2) C
Answer:
The first sequence is geometric because there is a common ratio of 6. The second sequence is arithmetic because there is a common difference of 3.
Step-by-step explanation:
Answer:
120 bricks = 10 kg
120 bricks × 10 kg = 1200 kg
1200 kg + 9000 kg = 10200 kg
Assume that 100% = 45 sales and 35% = X sales amount
You can create a ratio to help you solve for x
45 = 100%
x = 35 %
Which is equal to this fraction: (45/x) = (100/35)
Solving for X by cross multiplying and dividing by 100:
[(45)(35)] / 100 = X = 15.75 = 16 sales (rounded up)
You would need at least 16 sales to increase sales total by 35%
