Answer» Answer: no. of new boys = 84 Step-by-step explanation: let the ratio of girls to boys = 5x:3x ∴5x+3x=1440 ∴8x=1440 ∴x=1440/8 =180 ∴old No. of girls = 5x =5(180) =900 ∴old No. of boys = 3x =3(180) =540 no. of new girls = 36 ∴ New no. of girls = 900+36 =936 now, let the new ratio of girls to boys be 3y:2y ∴3y=936 ∴y=936/3 =312 ∴New no. of boys =2y =2(312) =624 ∴no. of new boys = New no. of boys - old no. of boys = 624-540 = 84 PLEASE MARK THIS ANSWER AS BRAINLIEST IF YOU THINK IT IS WORTH IT✌

The ratio of the number of girls to the number of boys in a college having 1440 students is 5:3. If 36 newgirls and some new boys are admitted to the college, the ratio of the number of girls to the number of boyschanges to 3 : 2. Find the number of new boys admitted to the college.

Answer»

Answer:

no. of new boys = 84

Step-by-step explanation:

let the ratio of girls to boys = 5x:3x

∴5x+3x=1440

∴8x=1440

∴x=1440/8

=180

∴old No. of girls = 5x

=5(180)

=900

∴old No. of boys = 3x

=3(180)

=540

no. of new girls = 36

∴ New no. of girls = 900+36

=936

now, let the new ratio of girls to boys be 3y:2y

∴3y=936

∴y=936/3

=312

∴New no. of boys =2y

=2(312)

=624

∴no. of new boys = New no. of boys - old no. of boys

= 624-540

= 84

23.	Q5. (a) Is it possible to have a regular polygonwith measure of each exterior angle22°?(b) Can it be an interior angle of a regularpolygon? Why?(pls explain if you can)
Answer» (a) Each EXTERIOR angle= 22° ∴NUMBER of sides = 360°/22° = 180/11 If it is a regular polygon, then its number of sides MUST be a WHOLE number. Here, 180/11 is not a whole number. ∴22° cannot be an exterior angle of a regular polygon (b) If 22° is an INTERIOR angle, then 180° - 22°, i.e., 158° is an exterior angle ∴The Number of sides = 360°/158° = 180°/79 which is not a whole number. Thus,22°cannot be an interior angle of a regular polygon.

23.

Q5. (a) Is it possible to have a regular polygonwith measure of each exterior angle22°?(b) Can it be an interior angle of a regularpolygon? Why?(pls explain if you can)

Answer»

(a) Each EXTERIOR angle= 22°

∴NUMBER of sides = 360°/22° = 180/11

If it is a regular polygon, then its number of sides MUST be a WHOLE number.

Here, 180/11 is not a whole number.

∴22° cannot be an exterior angle of a regular polygon

(b) If 22° is an INTERIOR angle, then 180° - 22°, i.e., 158° is an exterior angle

∴The Number of sides = 360°/158° = 180°/79 which is not a whole number.

Thus,22°cannot be an interior angle of a regular polygon.

46.	Divided 912 into 3 parts in the ratio 2:3:7PLEASE HELP!!!
Answer» Answer: 152,228,532 Step-by-step EXPLANATION: Ratio of division = 2:3:7 Let the NUMBERS be 2x, 3x and 7x So, 2x + 3x + 7x = 912 12x = 912 x = 912/12 = 76 Hence, 2x = 76 × 2 = 152 3x = 76 × 3 = 228 7x = 76 × 7 = 532 so the numbers are 152, 228, 532

46.

Divided 912 into 3 parts in the ratio 2:3:7PLEASE HELP!!!

Answer»

Answer:

152,228,532

Step-by-step EXPLANATION:

Ratio of division = 2:3:7

Let the NUMBERS be 2x, 3x and 7x

So,

2x + 3x + 7x = 912

12x = 912

x = 912/12 = 76

Hence,

2x = 76 × 2 = 152

3x = 76 × 3 = 228

7x = 76 × 7 = 532

so the numbers are 152, 228, 532
