A.
I=prt
I=(3800)(.055)(4/12)
I=$69.67
b.
Principal-interest=money received from Bank
3800-69.67=$3730.34
c.
I=prt
69.67=3730.34(r)(4/12)
69.67=1243.45r
69.67/1243.45=1243.45/1243.45r
.056≈r

The degree of the radian angle 0.11 is 
Explanation:
It is given that the radian angle is 0.11
We need to determine the degrees of the radian angle.
To convert the radian into degrees, let us multiply the radian with 
Thus, we have,

It is given that 
Substituting
in the above expression, we have,

Rounding off to the nearest tenth, we have,

Thus, the degree of the radian angle 0.11 is 
Answer: 1/2
Step-by-step explanation:
The question is for us to calculate the amount of juice that's left.
We are told that Luna mixes 3/4 of orange juice and 3/8 of cranberry juice. The amount of juice mixed will be:
= 3/4 + 3/8
= 6/8 + 3/8
= 9/8
= 1 1/8
We are then told that she gave Mags 5/8 cup of juice. The amount of juice that's then left will be:
= 1 1/8 - 5/8
= 4/8
= 1/2
1/2 cup of juice will be left
B=3d and b=d+4
Since b=b we can say:
3d=d+4 subtract d from both sides
2d=4 divide both sides by 2
d=2
