Acandy shop sells a box of chocolates for $30. it has $29 worth of chocolates plus $1 for the box. the box includes two kinds of candy; caramels and truffles. lita knows how much the different types of candies cost per pound and how many pounds are in the box. she said if x is the number of caramels included in the box and y is the number of pounds of truffles in the box then i can write the following equations based on what i know about one of these boxes:
x+y=3
8x+12y+1=30

how many pounds of candy are in the box?

what is the price per pound of the caramels?

what does the term 12y in the second equation represent?

what does 8x+12y+1 in the second equation represent?

Hurry if the population of of an ant hill doubles every 10 days and there are currently 100 ants living in the ant hill what will the ant population be in 20 days

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 > ?
