The ratio of boys to girls in a group is 7:1. If there are 66 more boys than girls, work out how many girls there are
IRISSAK [1]

Answer:11

Step-by-step explanation:

Boys : girls=7:1

Sum of ratio=7+1=8

Let number of girls be y

Then number of boys=y+66

Total number of pupils=y+y+66

Total number of pupils=2y+66

girls only=(girl ratio)/(sum of ratio) x (total number of pupils)

y=1/8 x (2y+66)

Cross multiply

y x 8=2y + 66

8y=2y + 66

Collect like terms

8y-2y=66

6y=66

Divide both sides by 6

6y/6=66/6

y=11

There are 11 girls

Triangle abc is congruent to triangle xyz in abc ab 12
Kipish [7]

A triangle is a polygon with three edges and three vertices, perimeter of ΔABC = 36cm.

<h3>Congruent triangles are what?</h3>

Congruent triangles are two triangles that are identical in terms of their size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.

Triangles with equal measures are congruent.

36cm = perimeter of ΔABC

Here we have,

ΔABC ≅ Δ XYZ

So,

= > 12 = XY = AB\\= > 14 = XZ = AC\\= > 10 =  YZ = BC\\

Therefore,  perimeter of ΔABC = 36cm
