Answer:
1. The nominal interest rate is 16.67%
2. The effective interest rate is 4.17%
Step-by-step explanation:
1.firstly we use the information given:
face value of bill is$100 which is denoted by Fv below.
$96 is the present value Pv of the bill denoted below.
thereafter we have n the number of periods of compounding which is 1 period.
we use the following formula for this problem to find i the nominal interest rate:

then we substitute the above mentioned values.
$100 = $96 ( 1+i/m)^1 divide both sides by $96
(100/96) = 1+ i/4 then subtract both sides by 1
(100/96)- 1 = i/4
0.0416666666667 = i/4 then multiply by 4 both sides as this was compounded quarterly so four times a year then multiply by 100 for percentage.
16.67% = i which is the nominal interest rate
2. 
ieffective= (1+16.67%/4)^1 - 1
ieffective = 4.17%
Answer:
Bailey family's sprinkler was used for 35 hours and Harris family's sprinkler was used for 20 hours.
Step-by-step explanation:
Set up a system of equations.
Let be "b" the time Bailey family's sprinkler was used and "h" the time Harris family's sprinkler was used.
Then:

You can use the Elimination method. Multiply the first equation by -15, then add both equations and solve for "h":

Substitute
into an original equation and solve for "b":

Answer:
6. B
7. D
Step-by-step explanation:
For 6 found that the 56 pieces in the first bag was about 18% of that bag. So then I found that 18% of 450 is ruffly 84, so B
For 7 I multiplied 5x5 is 25 so then 50x5 is 250, which is D
Answer:
Step-by-step explanation:
Use the Law of Cosines
A = arccos[(10²+14²-9.6²)/(2×10×14) ≅ 43.3°
