Angles 1, 2, and 3 are all 90°.
10x = 90
.. x = 9
x +y = 90
.. y = 81
5z = 90
.. z = 18
The values of (x, y, z) are (9, 81, 18).
Number of items an online shopping site sold per second = 420
Number of items it will sell in 30 minutes =
30 minutes = 1800 seconds
Number of items it will sell in 1800 seconds =
= 1800 × 420
= 756,000
∴ This online shopping site will sell 756,000 in 30 minutes .
The description shows a linear relationship and a proportional relationship.
<h3>How to describe the given relationship?</h3>
The given parameters are:
Charger = $15 per game
Customers are not charged to rent bowling shoes.
The statement "Customers are not charged to rent bowling shoes" means that the linear function has no y-intercept
So, the linear function can be represented as
y = Charges * x
This gives
y = 15x
Linear functions that are proportional functions are represented as y = mx
In this case, y = mx represents y = 15x
Hence, the description shows a linear relationship and a proportional relationship.
