Answer:

m∠KLM = 100

Step-by-step explanation:

First, make both equal to each other

26x + 22 = 38x - 14

Subtract 26x from both sides

22 = 12x - 14

Add 14 to both sides to isolate the variable

32 = 12x

Divide both sides by 12

x = 3

----------------- To find m∠KLM take one angle:

38x - 14

Replace the x with 3

38(3) - 14

Multiply 38 by 3

114 - 14

Subtract 14 from 114

100

m∠KLM = 100

Two consecutive odd integers are such that one-third the smaller is greater than one-seventh of the larger one by 6. Find the numbers.

Answers

Answer:

the number is 33 and 35 respectively

Step-by-step explanation:

The computation is shown below:

Let us assume X and X + 2 are the two consecutive odd integers

Now the equation is

(X ÷ 3) = ((X + 2) ÷ 7) + 6

(X ÷ 3) = (X + 2 + 6 × 7) ÷ 7

(X ÷ 3) = (X + 2 + 42) ÷ 7

(X ÷ 3) =  (X + 44) ÷ 7

Now do the cross multiplication

7X  = 3(X + 44)

7X = 3X + 132

4X = 132

X = 33

And, X + 2 = 33 + 2 = 35

hence, the number is 33 and 35 respectively

Tanya read 12 books for extra credit. She received 3.5 points for each nonfiction book and 1.5 points for each fiction book. If she received 28 extra credit points, how many of each kind of book did Tonya read?

Answers

Answer:

Tanya read 5 nonfiction books and 7 fiction books.

Step-by-step explanation:

Given that:

Number of books read by Tanya = 12

Points for nonfiction book = 3.5

Points for fiction book = 1.5

Total credit points received = 28

Let,

x be the number of nonfiction book read

y be the number fiction books read

According to given statement;

x+y=12     Eqn 1

3.5x+1.5y=28    Eqn 2

Multiplying Eqn 1 by 1.5

1.5(x+y=12)

1.5x+1.5y=18    Eqn 3

Subtracting Eqn 3 from Eqn 2

(3.5x+1.5y)-(1.5x+1.5y)=28-18

3.5x+1.5y-1.5x-1.5y=10

2x=10

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{10}{2}\\x=5[/tex]

Putting x=5 in Eqn 1

5+y=12

y=12-5

y=7

Hence,

Tanya read 5 nonfiction books and 7 fiction books.

Compound Interest Analysis With Applications

This site is a part of the JavaScript E-labs learning objects for decision making. Other JavaScript in this series are categorized under different areas of applications in the MENU section on this page.

Professor Hossein Arsham    

Compound Interest: The future value (FV) of an investment of present value (PV) dollars earning interest at an annual rate of r compounded m times per year for a period of t years is:

FV = PV(1 + r/m)mt

or

FV = PV(1 + i)n

where i = r/m is the interest per compounding period and n = mt is the number of compounding periods.

One may solve for the present value PV to obtain:

PV = FV/(1 + r/m)mt

Numerical Example: For 4-year investment of $20,000 earning 8.5% per year, with interest re-invested each month, the future value is

FV = PV(1 + r/m)mt   = 20,000(1 + 0.085/12)(12)(4)   = $28,065.30

Notice that the interest earned is $28,065.30 - $20,000 = $8,065.30 -- considerably more than the corresponding simple interest.

Effective Interest Rate: If money is invested at an annual rate r, compounded m times per year, the effective interest rate is:

reff = (1 + r/m)m - 1.

This is the interest rate that would give the same yield if compounded only once per year. In this context r is also called the nominal rate, and is often denoted as rnom.

Numerical Example: A CD paying 9.8% compounded monthly has a nominal rate of rnom = 0.098, and an effective rate of:

r eff =(1 + rnom /m)m   =   (1 + 0.098/12)12 - 1   =  0.1025.

Thus, we get an effective interest rate of 10.25%, since the compounding makes the CD paying 9.8% compounded monthly really pay 10.25% interest over the course of the year.

Mortgage Payments Components: Let where P = principal, r = interest rate per period, n = number of periods, k = number of payments, R = monthly payment, and D = debt balance after K payments, then

R = P × r / [1 - (1 + r)-n]

and

D = P × (1 + r)k - R × [(1 + r)k - 1)/r]

10 7

Answers

Answer:

We conclude that the first line number represents 1.5 + 2.5.

Step-by-step explanation:

Given the expression

[tex]1.5 + 2.5[/tex]

It means the first segment must represent 1.5 units starting from 0.

Since we have to add 2.5 to 1.5, so the next segment must represent 2.5 units, starting from 1.5

Combining them would make

[tex]1.5 + 2.5=4[/tex]

Now, if we observe the first number line,

The first arrow represents the 1.5 units starting from 0.The second arrow represents the 2.5 units starting from 1.5.The combined units of both arrows represent the length of 4 units. i.e. 1.5 + 2.5 = 4

Thus, we conclude that the first line number represents 1.5 + 2.5.

The correct line number is also attached below.
