Answer:
Difference in cash and plan = $155 - $149.50 = $5.50
Interest Rate = 3.68%
Step-by-step explanation:
Given:A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months
A food processor by cash = $149.50
Payment plan = Down payment + $10*15 months
= $5 + $10*15
= $5 + $150
Payment plan = $155
Difference in cash and plan = $155 - $149.50 = $5.50
Now we have to find the interest rate
= (difference/original)*100
= (5.50/149.50)*100
Interest Rate = 3.68%
You need to isolate the variable (x) by performing the opposite operation.
Since 3 is multiplied by x, the opposite would be dividing by 3. What you do on one side you do on the other side, so you would need to divide -12 by 3 as well.
In your case, the answer is B
13. Is 8
14. Is 10
15. Is D
Answer with Step-by-step explanation:
We are given that displacement of wave

Where y in cm and t in sec.
a.Compare it with

Amplitude of wave=A
We get A=1.5
Amplitude=A=1.5 cm
b.k=0.68


Using 
Wavelength of the wave=9.2 cm
c.Period=


The period of the wave=0.17 s
Speed of the wave=
Speed of the wave=54.1 cm/s
