The price of a pair of jeans is $25. If there is a 15% discount, what is the sale price of the jeans?

dusya [7]

Answer:

$29.41

Step-by-step explanation:

You know the discount price is 25 and the original is unknown so call it x. The sale is 15% off and that means that the jeans are 85% of what they used to be since 100-15 is 85. Then you plug it into a formula of 25/x = 85/100 then you cross multiply to get 2500=85x and when you solve for x and round you get $29.41

At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and

Ugo [173]

Answer:

Yes, he made a reasonable inference by saying about 25 percent of students choose the science.

Step-by-step explanation:

Given that

Number of students for survey = 50

Number of students who choose science = 12

Now

Percentage of student who choose science = $\frac{12}{50} x 100$

Percentage of student who choose science = $\frac{12*100}{50}$

Percentage of student who choose science = 24 %

Now as Mr. Yule said "about 25" percent of students choose the science it can be treated as reasonable approximation.

Now if the number of students in survey become 200, then we can expect 12 out of every 50 students would choose the science. So, in total 48 students would choose the science.

Now lets calculate the percentage of students who choose science.

Percentage of student who choose science = $\frac{48}{200} x 100$

Percentage of student who choose science = $\frac{48*100}{200}$

Percentage of student who choose science = 24 %

Naily [24]

Answer:

28.26 m^2

Step-by-step explanation:

Given that the area of a circle is $\pi r^2$ , we have to plug in the value of the radius and simplify. The radius is half the diameter, which is a line that splits the circle into halves. Thus, the radius here is 3. 3^2 is 9, and we can shorten pi to 3.14. 3.14 x 9 is 28.26, so the area of the circle is 28.26 m^2.
