What is the rate of return on a $12,500 bond purchased at $10,750 with a 15% coupon?
Firdavs [7]
With the 15% coupon, you will get $1,875. (Because 15% of the bond's price $12,500 is $1,875.) Solution: 0.15 x 12500 = 1875

So $1,875 is to be divided by the actual price of the bond which is $10,750. (1, 875 ÷<span>  10,750 = 0.1744 convert this to percent to get the rate of return)
 0.1744 = 17.44 %

The rate of return is 17.44%.</span>

Lindsey rows a boat downstream for 80 miles. The retum trip upstream took 12 hours longer. If the current flows at 3 mph, how fa
slamgirl [31]

Answer:

14hrs

Step-by-step explanation:

v = speed in still water

 

t = downstream trip time

 

d = distance = 182 miles; same distance both downstream and upstream

 

t + 12 = upstream return trip time

 

u = current flow = 3 mph

 

Downstream:  d = (v + u)t;  Upstream:  d = (v - u)(t + 12)

 

(v - 3)(t + 12) = 182  (equation 1)

(v + 3)t = 182  (equation 2)

 

Subtract equation 2 from equation 1 to get t:

 

(vt + 12v -3t -36) - (vt + 3t) = 0

 

12v - 6t - 36 = 0

 

t = 2v - 6

 

Substitute this result for t into equation 2 and solve for v:

 

(v + 3)(2v - 6) = 182

 

2v^2 - 6v + 6v - 18 = 182

 

v^2 = 100

 

v = 10 mph

 

t = 2v - 6 = [2(10) - 6] hrs = 14 hrs

What is the correct order of steps for bisecting angle ABC? Draw a ray from point B through point F. Keeping the compass the sam
Vitek1552 [10]

Answer:

Look to the explanation

Step-by-step explanation:

* Lets arrange the steps for bisecting angle ABC

- The vertex of angle ABC is B, and its rays are BA and BC

# Step 1:

- Place the compass on point B, and swing an arc that intersects rays

 BA and BC ⇒ 5th

# Step 2:

- Place point D on the intersection of the arc on ray BA and point E on

 the intersection of the arc with ray BC ⇒ 3rd

# Step 3:

- Place the compass on point D, and draw an arc inside the angle ⇒ 6th

# Step 4:

- Keeping the compass the same distance, place the compass on

 point E, and draw an arc inside the angle ⇒ 2nd

# Step 5:

- Place point F on the intersection of the arcs created from points D

 and E ⇒ 4th

# Step 6:

- Draw a ray from point B through point F ⇒ 1st

* This ray is the bisector of the angle ABC

7/10 divide by 1/5 - 4/3 x 10/11
Karolina [17]

Answer:

(-340)/231

Step-by-step explanation:

Simplify the following:

((-34)/33)/(7/10)

Multiply the numerator by the reciprocal of the denominator, ((-34)/33)/(7/10) = (-34)/33×10/7:

(-34×10)/(33×7)

33×7 = 231:

(-34×10)/231

-34×10 = -340:

Answer:  (-340)/231
