Divide the total amount of money Janice has by the cost of the stamps.

$7.20 / $0.30 = 24

Janice can buy**24 stamps.**

$7.20 / $0.30 = 24

Janice can buy

Question

Paige rides her bike around town. She can ride one half of a mile in 1 30 ith of an hour. If she continues to ride at the same pace, how many miles could she travel in 1 hour?

Solution 1

We have been given that Paige can ride one half of a mile in 1/30 th of an hour. And we have to found the distance traveled in 1 hour if she continues to ride at the same pace.

Let d be the distance traveled in 1 hour.

In 1/30 th of an hour distance traveled is 0.5 mile

Hence, in 1 hour the distance traveled is given by

**Therefore, she will travel 15 miles.**

Solution 2

She could travel 15 miles in an hour

Question

Miles had a piece of paper 1/4 of a large circle cut in three equal parts from the center point of the circle. What angle is the measure of each part?

Solution 1

The angle of 1/4 of a circle is given by:

Â (1/4) * (360) = 90 degrees

Â We now look for the angle that results from dividing 1/4 of a circle into three equal parts.

Â We have then:

Â (1/3) * (90) = 30 degrees.

Â**Answer:**

Â**the measure of each part is:**

Â**30 degrees**

Â (1/4) * (360) = 90 degrees

Â We now look for the angle that results from dividing 1/4 of a circle into three equal parts.

Â We have then:

Â (1/3) * (90) = 30 degrees.

Â

Â

Â

Solution 2

The **measure **of the **each part **of the **large circle **is **90 degrees.**

A **circle** is a bounded figure which points from its center to its circumference is equidistant. The sum of angles in a **circle **is 360 degrees.

Measure of the angle of each part = 1/4 x 360 = **90 degrees**

Question

In a class of 147 students, 95 are taking math(m), 75 are taking science (s), 52 are taking both math and science. What is the probability of randomly choosing a student who is taking neither math nor science? Round your answer to the nearest tenth

Solution 1

Subtract 52 from m, s, and the total amount of students.. 52 is the amount of students that would take both math and science. m now equals 43, s now equals 23, and the total students remaining is 95.

Since the criteria wants you to exclude students that take math or science, add m and s together.Â

This is the total amount of students that take math or science.

To find the probability of picking a student that doesn't take math or science, subtract 66 from the total amount of students.Â

Take this amount and divide by the total amount of students again.

Convert the decimal into a percentage.

Question

At a college, 4/5 of the students take an English class. Of these students, 5/6 Composition. Which fraction of the students at the college take Composition?

Solution 1

If Iâ€™m doing it correctly itâ€™s 2/3 but I havenâ€™t done it in a while

Question

Which situation is represented by the following equation?45w+123.95=753.95

Solution 1

45w+123.95=753.95

subtract 123.95 from both sides

45w+123.95-123.45=753.95-123.95

simplifying gives us:

45w=630

multiply both sides by 1/45

1/45Ã—45w=630Ã—1/45

simplifying we get

w=14

subtract 123.95 from both sides

45w+123.95-123.45=753.95-123.95

simplifying gives us:

45w=630

multiply both sides by 1/45

1/45Ã—45w=630Ã—1/45

simplifying we get

w=14

Question

A number, half of that number, and one fifth of that number are added. The result is 51. What is the original number?

Solution 1

Let the original number be â€˜xâ€™

Then half of that number= 1/2x or simply x/2

Similarly one fifth of that number = x/5

According to the question

x+x/2+x/5=51

Taking LCM

10x/10+2x/10+5x/10=51

Multiplying 10 throughout

10x+2x+5x=510

17x=510

x=510/17

Therefore x=30

Then half of that number= 1/2x or simply x/2

Similarly one fifth of that number = x/5

According to the question

x+x/2+x/5=51

Taking LCM

10x/10+2x/10+5x/10=51

Multiplying 10 throughout

10x+2x+5x=510

17x=510

x=510/17

Therefore x=30

Question

Dani measured the angles of a triangle as 125 degree, 36 degree, and 24 degree. Then, she measured the side lengths as 25.3 cm, 17.2 cm, and 11.8 cmon. She said that her triangle is an isosceles obtuse triangle. Do you agree? Explain.

Solution 1

No, because first of all 125 +36 + 24 should equal 180Â° not 185Â° because the area of a triangle always has an area of 180. Second, you don't even have to calculate anything because an isosceles triangle has two measures that are the sameÂ Â°âˆžÂ° Hope this helps!

Question

Meredith has 8 pens and 9 pencils. Brody has 4 pens and 9 pencils. Which is the correct comparison of their ratios of pens to pencils?

Solution 1

**Answer:**

**Step-by-step explanation:**

We have been given that Meredith has 8 pens and 9 pencils. Brody has 4 pens and 9 pencils.

We can see that Meredith and Brody has same number of pencils, but Meredith has more pens than Brody.

We can represent the pen to pencils ratio for Meredith and Brody as:

We can compare the pens and pencils proportions that Meredith and Brody have as:

**Therefore, is the correct comparison of their ratios of pens to pencils.**

Solution 2

8/9 > 4/9

Meredith has more pens to pencils than Brody

Meredith has more pens to pencils than Brody
