Which two equations can you use to find the adult and child admission fees for a puppet show? Let a represent the fee for adults and c represent the fee for children. Adults Children Admissions Collected
Day 1
45
30
$315
Day 2
50
40
$370
45c + 30a = 315
45a + 50c = 315
45a + 30c = 315
50c + 40a = 370
50a + 40c = 370

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )

Ithink it’s d as the answer.
