Answer:

45 adults, 30 boys, 105 girls

Step-by-step explanation:

Adults --- 3 units

Boys --- 2 units

Girls --- 7 units

Total

= 3 +2 +7

= 12 units

Since there are 180 people in total,

12 units --- 180 people

1 unit --- 180 ÷12= 15 people

Number of adults

= 3(15)

= 45

Number of boys

= 2(15)

= 30

Number of girls

= 7(15)

= 105

Given RT below, if S lies on RT such that the ratio of RS to ST is 3:1, find the coordinates of S.
Ksivusya [100]

Answer:

S(-2, -3)

Step-by-step explanation:

Find the diagram attached below,=. Frim the diagram, the coordinate of R and T are (-5, 3) and (-1, -5) respectively. If the ratio of RS to ST is 3:1, the coordinate of S can be gotten using the midpoint segment formula as shown;

S(X, Y) = {(ax1+bx2/a+b), (ay1+by1/a+b)} where;

x1 = -5, y1 = 3, x2 = -1, y2 = -5, a = 3 and b =1

Substitute the values into the formula;

X = ax2+bx1/a+b

X = 3(-1)+1(-5)/3+1

X = -3-5/4

X = -8/4

X = -2

Similarly;

Y = ay2+by1/a+b

Y = 3(-5)+1(3)/3+1

Y = -15+3/4

Y = -12/4

Y = -3

Hence the coordinate of the point (X, Y) is (-2, -3)
