Answer:
k=-1/5
Step-by-step explanation:
1/2(10k-16)+11=-2
5k-8+11=2
5k+3=2
5k=-1
k=-1/5
1) 129.48 lbs : Multiply 156 by 0.17 to get 26.52, then 156 by 26.52 to get 129.48.
2) 1.96 : take 166.52 and divide that by 85. You will get 1.9590... and a lot of other crazy numbers. Round it to the nearest cent, you get 1.96.
3) 0.93 minutes : the faster time is 9.97 and the slowest is 10.9, subtract that and get 0.93.
4) 20.75 : add the prices up all together and you get 20.75
5) 18.32
6) 16.754
7) 56.44
8) I can't see the sign
9) 161.7
10) 737.49
11) 250
12) 405
13) 54.67
Angle 1 and 2 are vertical angles
Hope this helps :)
The annual interest rate is 3.5%.
Solution:
Given Interest (I) = $26.25
Principal (P) = $500
Time (t) = 18 months
Rate of interest (r) = ?
Time must be in years to find the rate per annum.
1 year = 12 months
Divide the time by 12.
Time (t) = 
years
Now, find the rate of interest using simple interest formula.
<u>Simple interest formula:</u>
⇒ r = 3.5%
Hence the annual interest rate is 3.5%.
1; (1/4)/(1/4), all you do is flip the fraction to make the reciprocal and multiply, so (4/1)x(1/4)=1
