The number of students in Mrs. Patrick's piano class decreased by 15% in 2 years to 17 students. How many students did she have

guapka [62]

Answer:

20 students

Step-by-step explanation:

If the class decreased by 15%, the students that she has now (17) represents a percentaje of:

100% - 15% = 85%

so the 17 students are 85% of what she had:

Students Percentage

17 ⇒ 85%

and we are looking for how many students she had 2 years ago, thus we are looking for the 100% of students (the original number of studens). If we represent this number by x:

Students Percentage

17 ⇒ 85%

x ⇒ 100%

and we solve this problem using the rule of three: multiply the cross quantities on the table( 17 and 100) and then divide by the remaining amount (85):

x = 17*100/85

x = 1700/85

x=20

2 years ago she had 20 students

The Least common multiple of two numbers is 60, and one of the numbers is 7 less than the other number. What are the numbers? Ju

Korvikt [17]

The n two number are n and n+7. The two numbers are relatively prime because 7 is prime and doesn't divide 60. So we get n(n+7)=60. Guess and check tells us the two numbers are 5 and 12.

The surface area of a right square pyramid is given by A=b2+2bh where b is the length of a side of the base and h is the slant h

gizmo_the_mogwai [7]

Answer:

$h = \dfrac{A - 9}{6}$

Step-by-step explanation:

A=b^2+2bh

b = 3

A = 3^2 + 2(3)h

A = 9 + 6h

6h = A - 9

$h = \dfrac{A - 9}{6}$
