Sorry, I need to know the options (answer choices) to answer this question.
I think its talking about proportional or non-proportional.. if it is its proportional
No It can not . I hope this is the correct answer
Answer:
1) C
2)C
3)B
4)A
Step-by-step explanation:
1) Circle
Solve for area
A≈28.27cm²
d=Diameter 6cm
Using the formulas
A=πr2
d=2r
Solving for A
A=1
4πd2=1
4·π·62≈28.27433cm²
2)
To calculate 5% of a number, simply divide 10% of the number by 2. For example, 5% of 230 is 23 divided by 2, or 11.5.
The rate for the first is 1 job / 35 minutes and for the second is 1 job / 15 minutes. So combined we get
r = 1/35 + 1/15
3×5×7r = 3 + 7 = 10
r = 10/(105) jobs per minute
We're interested in 1/r
1/r = 105/10 = 10.5 minutes per job
Answer: 10.5 minutes
