Answer:

<u>Admission prices are $3 per child and $4 per adult.</u>

Step-by-step explanation:

Let the admission prices for children = x and for adults = y

When the pool had 10 children and 37 adults, which brought in $178

10x + 37y = 178 ⇒(1)

When the pool had 15 children and 23 adults, which brought in $137

15x + 23y = 137 ⇒(2)

Multiplying eq.(1) by 3  ⇒ 30x + 111y = 534 ⇒(3)

Multiplying eq.(2) by 2 ⇒ 30x + 46y = 274 ⇒(4)

Find eq.(3) - eq.(4)

∴ 111y - 46y = 534 - 274

∴ 65y = 260

∴ y = 260/65 = 4

By substitution with y at eq.(1)

10x + 37 * 4 = 178  ⇒ solve for x

10x = 178 - 37*4 = 30

∴ x = 30/10 = 3

<u>So, Admission prices are $3 per child and $4 per adult.</u>

In a circle, chords ST and RA intersect at Y such that SY is perpendicular to RY. The value of mSA + mRT is: a. 90º b. 180º c. 2
pshichka [43]

Answer:

a. 90º

Explanation:

The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.
