Given:
Girls = 25
Boys = ?
Number of students who prefer tap dance = 9
percentage of students who prefer tap dance = 20%

We need to divide 9 by 20% to get the total number of students who filled out a survey.

9 ÷ 20% = 45 total number of students

Girls + Boys = 45
25 + Boys = 45
boys = 45 - 25
boys = 20

The correct equation is: B. 0.2(x + 25) = 9

0.2x + 5 = 9
0.2x = 9 - 5
0.2x = 4
x = 4 / 0.2
x = 20

B . Because it explains their was 25 girls and some boys so you add x to the 25
(X+25)0.2= 9

The length of a picture is 15.75 inches shorter than twice the width. If the perimeter of the picture is 106.5 inches, find its
Vladimir79 [104]

Answer:

Length = 45.37 in

Width = 30.56 in

Step-by-step explanation:

Let the width of the picture be 'w' inches.

Given:

Perimeter of the picture is, P=106.5\ in

Length is 15.75 inches shorter than twice the width. So, length is:

l=2w-15.75

Now, we know that the perimeter of a rectangular shape is given as the sum of all of its side. So, the picture is also of rectangular shape and hence the perimeter is given as:

P=2l+2w

Plug in the values of 'l' and 'P' and solve for 'w'. This gives,

106.5=2w-15.75+2w\\106.5=4w-15.75\\106.5+15.75=4w\\4w=122.25\\w=\frac{122.25}{4}=30.56\ in

Therefore, the width of the rectangular picture is 30.56 inches.

Length of the picture is, l=2(30.56)-15.75=61.12-15.75=45.37\ in

So, length of the picture is 45.37 inches and width is 30.56 inches.

What is the arc length when theta=2 pi/5 and the radius is 6 cm
Crank

Answer:

The length of the arc is 7.536cm

Step-by-step explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 6cm

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 6cm

c = 37.68cm

The length of the circumference is 37.68cm

Now we calculate the fraction that corresponds to this arc with the rest of the circumference

(2 pi /5) / (2pi) = 1/5

now we multiply the circumference by the fraction

37.68cm  * 1/5 = 7.536cm

The length of the arc is 7.536cm
