There are 165 adults and 280 children at a zoo. The zoo makes a total of $6,610 from the entrance fees, and the cost of an adult and a child to attend is $31, how much does it cost each for a parent and a child? Let a represent an adult.
Let c represent a child.

Enter a system of equations to represent the situation, then solve the system.

The system of equations is .

The adult tickets cost $
and the child tickets cost $
.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
