Answer:

Rational

Step-by-step explanation:

okay so a natural number is anything like 1,2,3,4...etc.

a whole number is like a natural number but includes 0's

an integer is numbers that can have both positive and negative numbers

but keep in mind all of these are whole numbers or can be made into a whole number (not including natural numbers)

this leaves...

Rational

now here is a word of advice every mixed number and fraction is rational because its already in a solved and complete form but a decimal that could be solved like 0.77777 or 0.345 with a line over it or 64 squared

Irrational

a number that has no end and cant be solved like 0.86866968..... or 38 squared

Using the scale 1/2 inch = 100 miles, figure out the number

Wittaler [7]

Answer:

50 miles

Step-by-step explanation:

Multiply the given scale numbers by 1/2 to find your answer:

1/2 in = 100 mi

(1/2)(1/2 in) = (1/2)(100 mi) . . . . multiply the ratio values by 1/2

1/4 in = 50 mi

Ana has won a lottery. She was offered two options to receive the award: She can either take it in five installments of $60,000

AleksandrR [38]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

She can either take it in five installments of $60,000 annually, starting from now; or she can take a lump-sum of $255,000 now.

First, we determine the value of the 5 installments using a 5% annual compounded rate.

We calculate the future value, and then the present value:

FV= {A*[(1+i)^n-1]}/i

A= annual payments

FV= {60,000*[(1.05^5) - 1]} / 0.05

FV= $331.537.88

PV= FV/(1+i)^n

PV= $259,768.60

At an annual rate of 5% compounded annually, she should choose the five installments instead of the $255,000.

Now, if the annual rate is 6% continuously compounded.

First, we need to calculate the effective interest rate:

r= e^i - 1

r= effective inerest rate

r= e^0.06 - 1

r= 0.0618

FV= {60,000*[(1.0618^5) - 1]} / 0.0618

FV= 339,443.23

PV= 339,443.23/1.0618^5

PV= $251,509.01

At an annual rate of 6% compounded continuously, she should choose the $255,000.

Find a in the figure below and place the value in the empty box

AleksAgata [21]

Answer:

a = 12m

Step-by-step explanation:

In order to solve this problem we will need to know the Pythagoras theorem that states that in a right angled triangle the square of the hypotenuse (the side opposite to the right angel) is equal to the sum of the squares of the other two sides. This theorem can be written as an equation....

$c^{2} = a^{2} + b^{2}$
