A light rail system traveling between cities averages 50 mph. How much time does it take to travel 120 miles?

Answer:

.66 (repeating) or the rounded answer is .67

Step-by-step explanation:

1/2 times 2/3 = .33(repeating)

.33(repeating divided by 1/4 = 1.33(repeating)

1.33(repeating) times 1/2 = .66(repeating)

Answer: No.

Step-by-step explanation:

    No, these ratios are not equal. We can view these ratios as fractions and divide to see if they are equal.

         3:6 = = 0.5

         6:3 = = 2

    No, 0.5 ≠ 2.

Answer:

y = 2x + 11

Step-by-step explanation:

Slope-intercept form (y=mx+b) of linear equations highlights the slope (m) and the y-intercept (b) of a line.

Slope = m = rise/run = (y2-y1)/(x2-x1) = (15-21)/(2-5) = -6/-3 = 2

substitute 2 back into the equation.

y = mx + b

y = 2x + b

use one of the provided points to solve for b.

y = 2x + b

15 = 2(2) + b

15 = 4 + b

11 = b

y = 2x + 11

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The percentage of students who packed their lunch is 60%.

Option B is the correct answer.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Requiredpercentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50 /100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Of the students in sixth grade:

The number of students who packed their lunch = 3/5

This means,

Out of 5 students, 3 packed their lunch.

We can find the percentage by multiplying 3/5 by 100.

= 3/5 x 100

= 3 x 20

= 60%

Thus,

The percentage of students who packed their lunch is 60%.

Option B is the correct answer.

The percentage of students who pack lunch is 60%.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have of all the students in sixth grade, 3/5 pack their lunch.

Assume that the percentage of students who pack lunch is [x]%. So -

x% = 3/5 x 100 = 60%

Therefore, the percentage of students who pack lunch is 60%.
