A principal of $835 in an account at 3% per quarter simple interest

Tems11 [23]

Take $835 and multiply by 0.3 and you get $25.05
If you add $25.05 to $835 you will get $860.05
Keep adding $25.05 and you will have sums of $885.10, $910.15, $935.20

The ratio of an object's weight on Earth to its weight on Neptune is 5 : 7. How much would a person who weighs 150 pounds on Ear

shutvik [7]

5:7
In english, what this is saying is that for every 5 units of weight on Earth, is 7 units of weight on Neptune.
Given this, it would make sense that your weight on Neptune, say Y, equals your weight on Earth, say X, divided by five, then multiplied by seven.
Y = (X/5) * 7
Y = (150/5) * 7 = 210

Which set of ordered pairs has point symmetry with respect to the origin (0, 0)? (5, 4), (-5, -4) (5, 4), (5, -4) (5, 4), (4, 5)

Sidana [21]

The set of ordered pair that has point symmetry in respect to origin is (5, 4), (-5, -4).

<h3>What is the point of symmetry?</h3>

This is a term that is used to refer to the points that are on the same distance from the origin but are on opposite sides.

The line that connects the points are known to move through the origin such that when measured on the graph, the distances between these points but they are opposite because they are in negatives and positives on the two sides.
