Answer:4.5
Step-by-step explanation:
2+3+1=6, 3 divided by 6 equals to 1/2. 1/2 times 9 equals 4.5 pounds of walnuts
Answer: 108 miles
There is 6 miles per hour
Multiply 6x18=108

Answer:
tan(C) = 3/4
Step-by-step explanation:
If the sine of angle C is 3/5 and we want to find the tangent of the angle C, we can first find the cosine of angle C using the following equation:
Then, we can find the tangent relation using the equation:
Using the formula
ending amount is 1649=a
p=initial amount=100
t=10
r=r
so
1649=100e^{10r}
divide both sides by 100
16.49=e^{10r}
take ln of both sides
ln(16.49)=10r
divide both sides by 10
(ln(16.49))/10=r

0.28027=r
