Answer:

The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles

Step-by-step explanation:

The given parameters are;

The distance between the two cyclist when they begin biking away from each other = 7 miles

The first cyclist's speed = 12 miles per hour

The second cyclist's speed = 12 + b miles per hour

Therefore, we have;

The equation for distance covered, d = Speed × Time

The distance covered by the second cyclist in 45 minutes, d_{45 \ minutes} is given as follows;

45 minutes = 3/4 hour

d_{45 \ minutes}  = (12 + b) × 3/4 = (3/4·b + 9) miles

The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.

A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many
vodomira [7]

Answer:

The number of students who prefer chocolate milk is 780 .

Step-by-step explanation:

Given as :

The total number of students in the school = 1200

The percentage of students who prefer plain white milk = 35 %

Let the number of students who prefer chocolate milk = x

Now, ∵ The percentage of students who prefer plain white milk = 35 %

∴ The percentage of students who prefer chocolate milk = 100 % - 35 % = 65%

So , As The number of  students who prefer chocolate milk = x

Or, 65 % of total number of students in school = x

So, x = \frac{65}{100} × 1200

or, x = \frac{65\times 1200 }{100}

∴  x = 780

So, the number of students who prefer chocolate milk = x = 780

And  students who prefer plain white milk = 1200 - x = 1200 - 780 = 420

Hence, The number of students who prefer chocolate milk is 780 . Answer
