Paula has a dog that weighs 3 times as much as Carla's dog. The total weight of the dogs is 48 pounds. How much does Paula's dog
spayn [35]
Let the weight of Paula's dog be x
Let the weight of Carla's dog be y

We know that the weight of Paula's dog is 3 times that of Carla's dog, therefore:
x = 3y ...........> equation I

We also know that the sum of the weights is 48 pounds, therefore:
x + y = 48 ............> equation II

Substitute with equation I in equation II:
3y + y = 48
4y = 48
y = 12 pouds

Substitute with the value of y in equation I:
x = 3(12) = 36 pounds

Based on the above calculations:
Paula's dog weighs 36 pounds
Carla's dog weighs 12 pounds

A regular pentagon has an apothem of 3.2 m and an area of 37.2 square meters. What is the length of one side of the pentagon?
blondinia [14]
Area = # sides * side length * apothem / 2
side length = (2 * area) /  # sides * apothem
side length = 2 * 37.2 / 5 * 3.2
side length = 74.4 / 16
side length = 4.65 meters

AXYZ is rotated 180°.<br> What are the coordinates of point X'?
vredina [299]
<h3>Answer:  (4, -1)</h3>

Reason:

When rotating a point 180 degrees around the origin, you use the rule

(x,y) \to (-x,-y)

We flip the sign of each coordinate from positive to negative or vice versa.

The point X is at the location (-4, 1). Rotating this 180 degrees will get us to X'(4, -1)
