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.

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.

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 I’m doing it correctly it’s 2/3 but I haven’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

1/45×45w=630×1/45

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

1/45×45w=630×1/45

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 ‘x’

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 180° not 185° 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 same °∞° 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

Question

What is the volume of a right circular cylinder with a base diameter of 18yd. And a height of 3yd.

Solution 1

**Answer:**

to the nearest cubic yard.

**Step-by-step explanation:**

The volume of a right circular cylinder can be calculated using the formula;

.

The diameter of the base is given to us. We divide it into two to obtain the radius.

and also the height of the cylinder is .

We substitute these values into the formula to obtain;

Solution 2

Question

21$is 75% of what amount?

Solution 1

21 cents =75%

divide both sides by 3

7cents= 25%

multiply each side by 4

28=100%

Answer=28

divide both sides by 3

7cents= 25%

multiply each side by 4

28=100%

Answer=28

Question

Mara ran 3km north ad then 4km east. she will finish her run by running directly home. What is the total distance of her run

Solution 1

So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add that distance to 3 and 4.

By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...

d^2=3^2+4^2

d^2=9+16

d^2=25

d=√25

d=5

So the total distance of her run is 5+4+3=12 km

By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...

d^2=3^2+4^2

d^2=9+16

d^2=25

d=√25

d=5

So the total distance of her run is 5+4+3=12 km

Solution 2

You can solve this with the Pythagorean theorem.

9+16=25, and the square root of 25 is 5. This is your answer.

9+16=25, and the square root of 25 is 5. This is your answer.
