Answer:
For each hour Cara works, she earns $10.
Step-by-step explanation:
You could see that on the graph that for 5 hours Cara has worked, she earns 50 dollars. The slope would be 50/5. 50/5 is equal to 10/1 through dividing so Cara earns $10 for each hour she works.
Step-by-step explanation:
a) (i) length = 2(pi)r = 2(3.14)(.5 m) = 3.14 m
(ii)3.14 m × ($4.70/m) = $14.76
b) A = (pi)r^2 = (3.14)(18 m)^2 = 1017.9 m^2
Answer:
The cost of parts was $65.
Step-by-step explanation:
Let the cost of parts = x
35 + 21(3) + 1.10x = 169.50
98 + 1.10x = 169.50
71.50 = 1.10x
71.50/1.10 = 65
