Suppose that you have ​$4,000 to invest. Which investment yields the greater return over a 10 year​ period: 8.03% compounded daily or ​8.1% compounded​ quarterly? Find the total amount of the investment after 10 years if ​$4,000 is invested at ​8.03% compounded daily.

Answers

A = 5000(1+.0743/365)365(10)
= 5000(1.000203562)3650 = $10,510.38

A = 5000(1+.075/4)4(10)
= 5000(1.01875)40 = $10,511.75

As you can see these are practically equal, but the 7.5% quarterly is more.

Ralph is arranging a wedding reception. He can spend no more than $8000. It costs $6000 to rent the hall and $25 to feed each guest. Ralph needs to know how many guests, at most, can attend the reception. Write an inequality to represent this situation.

Answers

Answer:  

80 ≥ x

Step-by-step explanation:

So we know that he cannot spend more than $8000.

So we subtract 6000 from 8000

8000 - 6000 =2000

So that means $2000 to feed each guest

We then divide the amount of money we have left by how much it costs to feed each guest.

2000÷25=80

So at most 80 guests will be able to attend. I'll use x to represent the amount of people that will attend the reception.

So 80 ≥ x

a.7.5
b.12.5
c.80
d.0.5

Answers

Answer:

A. 7.5

Step-by-step explanation:

15 / -6 +x = 10

15 /-6 +x * (-6+x) = 10 * (-6+x ) : multiply both sides by -6+x

15 = 10(-6+x) : simplify

15 = -60+10x : distribute

15+60 = 10x : addition property of equality

75/10=10x/10 : division property of equality

x = 7.5

The figure shows the location of three points around a lake. The length of the lake, BC, is also shown.

(The figure is not drawn to scale.)

A picture of a right triangle ABC with right angle at B is shown. The length of the side AC is labeled as 6 miles. The length BC of the triangle is labeled as 2 miles. This length BC is also the length of an irregular gray shaded shape.

Which of the following choices is closest to the distance (in miles) between points A and B?

3.46 miles
5.66 miles
6.32 miles
7.75 miles

Answers

A right triangle ABC is formed when we join three points around a lake.
Length of the side AC = 6 miles.
Length of the side BC = 2 miles.
We have to find Length of side AB.
Using Pythagorean theorem for Right triangle ABC , Right angled at B
→AB² + BC²= AC²
→ AB² + 2²= 6²
→ AB² = 36 - 4
→ AB²= 32
→ AB = √ 32
→→AB = 5.66 (approx)
Option (B) AB = 5.66 is Right choice.
B 5.66 is the right answer
