Supplement is 180- angle
180-95 = 85
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
18 is the answer you're welcome
Answer:
11x + y = 25
Step-by-step explanation:
Start with y = mx + b
Slope is -11, so m = -11
Point is (2, 3), so we plug that back in to get the intercept.
3 = -11 * 2 + b
3 = -22 + b
b = 25
y = -11x + 25
11x + y = 25 in standard form.
The questions seems to be lacking some information. By rate I'm going to assume position and in that scenario the answer would be B because the position function is modeled by a linear function.
