He saved 30.25 last month. 169 - 48 = 121 divided by 4 = 30.25
Answer:
A. 13, 10, 16
Step-by-step explanation:
If three sides of triangle have measures a, b and c, then
Check all options:
A. a=13, b=10, c=16
Thus,
This option is true
B. a=1, b=2, c=3
Then
but 
must be greater than c, so
this option is false
C. a=5.2, b=11, c=4.9
Then
but 
must be greater than b, so
this option is false
D. a=208, b=9, c=219
Then
but must be greater than c, so
this option is false
Hey!
91 ÷ 7 = 13
So, we know that Luke paints one portrait every week.
13 × 4 = 52
So, Luke paints 52 portraits in 4 weeks.
The pricing scheme of the function is (a) The first two hours cost $2, between two hours and six hours cost $2 per hour, and all hours after that cost $1.
<h3>How to determine the pricing scheme?</h3>
The points are given as:
- Constant = (0,2) to (2, 2)
- Another = (2,2) to (6,10)
- Another = (6,10) to (7,11)
The constant interval implies that the first two hours cost $2
Next, we calculate the slope/rate of the other points.
This is done using
m = (y2 - y1)/(x2 - x1)
So, we have:
m1 = (10 - 2)/(6 - 2) = 2
m2 = (11 - 10)/(7 - 6) = 1
This means that:
- The next 4 hours are charged for $2 per hour
- All hours after that cost $1
Hence, the pricing scheme of the function is (a)
