Answer:

Perimeter = 20cm

The perimeter is 35 for the larger triangle = 7:4 ratio

the perimeter for the smaller triangle = 4:7 ratio

We add up 4+7 = 11 and multiply 35 x 2 = 70.

so that the smaller triangle = 40  = 40:70

35 = 7 and 20 = 4

To find measurements of 20

we have any number over 10 combined will make the smaller sides possible,

Where hypotenuse would be under 10.

H = 6.5 Sides = 6 + 5 does not add up to 20

H = 9 Sides = 7 + 4  does have near equal spaced symmetry.

H = 9  Sides = 5 + 6  is wrong as no symmetry in measure

H = 8  Sides = 7 + 5 is wrong as no symmetry in measure

H = 7 Sides = 6 + 7  is wrong as equal sides

H = 6 sides = 6.5 + 6.5 is wrong as equal sides

H = 11 Sides = 6 + 3 is wrong has no symmetry.

The measurements must be 9cm, 7cm and 4 cm for the smaller triangle

The perimeter adds up to 20cm.

Adult ticket (a) = $5
Child ticket (c) = $2

785 tickets = $3280

a + c = 785 tickets
5a + 2c = $3280

c = 215 child tickets
a = 570 adult tickets

570 + 215 = 785 tickets
5(570) + 2(215) = $3280

There were 215 child tickets sold on Saturday

Answer:

102.5, 103.5

Step-by-step explanation:

a+a+1=206

2a+1=206

2a=205

a=102.5

103.5

I think there is a bug here. They can't be whole numbers.
