Answer:

Option D: 2\frac{1}{2} minutes is the correct answer.

Step-by-step explanation:

Given that:

Darius needs to solve 45 math problems. He as already solved 15 problems.

Remaining problems to be solved = Total - Already solved

Remaining problems = 45-15 = 30 problems

Time worked = 3:15 to 4:30 = 75 minutes

Darius have 75 minutes to solve 30 problems.

Time for one problem = \frac{remaining\ problems\ to\ solve}{time\ worked}

Time for one problem = \frac{75}{30} = \frac{5}{2}\ minutes

Time for one problem = 2\frac{1}{2}\ minutes

It takes Darius 2\frac{1}{2} minutes to complete one problem.

Hence,

Option D: 2\frac{1}{2} minutes is the correct answer.

On your family trip, you used 9 gallons of gas. If the odometer readings before and after your trip were 74,233 and 74,545, resp
sveta [45]

Find the number of miles driven by subtracting the odometer readings:

74545 - 74233 = 312 miles driven.

Divide miles driven by gallons of gas used:

312 / 9 = 34.66 = 35 miles per gallon.

8 19. Marcus claims that fractions with denominators 1 through 10 follow a pattern
navik [9.2K]

Answer:

No

Step-by-step explanation:

Marcus is not correct because 1/12 converts to the repeating decimal 0.8333... but 3/12 converts to 0.25 which is not a repeating decimal.

39/250 in simplest form
OleMash [197]
Getting the simplest form of a fraction is the same with getting its lowest term. Reducing fractions to its lowest term is a very simple thing to do. Here's how to simplify fractions:

There are two ways in simplifying fractions. The first method is to equally divide both numerator and denominator which results to only whole numbers. Getting the GCF (Greatest Common Factor) or GCD (Greatest Common Divisor) is the second method.

As to the fraction above, 39/250, the second method is applicable.
Let us get the GCF of 39 and 250
39= 1,3,13,39
250= 1, 2, 5,  10, 25, 50, 125, 250

Therefore, the GCF of 39 and 250 is 1. We can conclude then that 39/250 is already on its simplest form thus;
  <u>39</u>  ÷     <u>1</u> is equal to     <u>39</u>
 250       1                       250

3(x-8) = -29.7 please solve for x
GrogVix [38]

Answer:

The answer is x= -1.9.

Use the 3 to multiply the number and the letter in the bracket... which is...

3x-24=-29.7.

3x=-29.7+24.

3x=-5.7.

x=-5.7/3.

x=-1.9.

For the given angle 0, identify the reference angle, _
ankoles [38]

Answer:

π\6

Step-by-step explanation:

The reference angle is the smallest angle measured from the terminal side of the angle (where the angle ends) to the x axis. The reference angle is an acute angle (i.e less than 90° or π/2)

For O = 11π/6 = 1.833π

1.833π is in the fourth quadrant between 3π/2 radians and 2π radians. Since it is in the fourth quadrant, the reference angle is given as:

reference angle = 2π - 11π/6 = π\6
