Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>The equation for simple interest:</u>
<u>And values</u>
<h3>Solution</h3>
<u>Interest amount is</u>
<u>Solving for annual interest rate</u>
- 160 = 2000*2r
- 160 = 4000r
- r = 160/4000
- r = 0.04
- 0.04*100% = 4%
Annual interest rate is 4%
Answer:
and 
Step-by-step explanation:
12x+7<-11 subtract 7 from both sides 12x<-18 divide both sides by 12 x<1.5
5x-8>40 add 8 to both sides 5x>48 divide both sides by 5 x>9.6
Answer:
12 unit^2.
Step-by-step explanation:
Surface area = area of the square + 4 times the area of one triangle
= 2 * 2 + 4 * (1/2 * 2 * 2)
= 4 + 4* 2
= 12
W = 195
2/5D = 4/5W
2/5D = 4/5(195)
2/5D = 156
D = 390
