olchik [2.2K]

Answer:

12 boys

Step-by-step explanation:

From the above question:

Number of boys = 3

Number of girls = 2

Boys: Girls

3:2

Let :

a = boys

b = girls

Hence, a : b = 3 : 2

a/b = 3/2  

Cross Multiply

2a = 3b .......... Equation 1

a = 3b/2

If four more girls join the class, there will be the same number of boys and girls

Hence,

a: b + 4 = 3 : 3

a/b + 4 = 3/3

Cross Multiply

3a = 3(b + 4)

3a = 3b + 12 ........ Equation (2)

From Equation 1: a = 3b/2

Substitute 3b/2 for a in Equation 2 we have:

3a = 3b + 12 .........Equation 2

3(3b/2) = 3b + 12

9b/2 = 3b + 12

Cross Multiply

9b = 2(3b + 12)

9b= 6b + 24

9b - 6b = 24

3b = 24

b = 8

Substitute 8 for b in Equation 1

a = 3b/2

a = 3 × 8/2

a = 24/2

a = 12

Therefore, the number of boys in the class is 12

Answer:

perimeter=25.12 ft

Area=50.24 ft^2

Step-by-step explanation:

Radius=4 feet

π=3.14

Perimeter=2 x π x Radius

Perimeter=2 x 3.14 x 4

Perimeter=25.12 feet

Area=π x radius x radius

Area=3.14 x 4 x 4

Area=50.24 ft^2

GEOMETRY AID URGENT?
weeeeeb [17]

Lets assume center point of circle as O

OD is the radius of circle . so OD is also 7

All the sides of the triangle are equal . so angle at the center O is 60 degree.

radius = 7

Length of arc CD = \frac{theta}{360} * 2*\pi*r

= \frac{60}{360} * 2*\pi*7

= \frac{1}{6} * 2*\pi*7

= \frac{7\pi}{3}
