Answer:
the value of 8 in the first one is 8
in the second one is 80
The answer is C (EF and HI)
This is because both lines pass through the centre A, meaning both are diameters. Hence, they are equal in length.
Answer:
C, 6
Step-by-step explanation:
31-13 is 18, 18/3 is 6.
Assuming simple interest (i.e. no compounding within first year), then
At 6%, interest = 10000*0.06=$600
At 9% interest = 10000*0.09 = $900
Two ways to find the ratio
method A. let x=proportion at 6%
then
600x+900(1-x)=684
Expand and solve
300x=900-684=216
x=216/300=0.72 or 72%
So 10000*0.72=7200 were invested at 6%
10000-7200=2800 were invested at 9%
method B: by proportions
Ratio of investments at 6% and 9%
= 900-684 : 684-600
=216 : 84
= 18 : 7
Amount invested at 6% = 18/(18+7) * 10000 = 0.72*10000 = 7200
Amount invested at 8% = 7/(18+7)*10000=0.28*10000=2800
Answer:
No, because the number in 2011 multiplied by three is less than the number in 2015.
