Answer:

Yes it is

Step-by-step explanation:

A rational number is any number that can be expressed within a fraction or has a repeating pattern. 11/7 is rational, 12 is rational, and even 0.33333 is rational. Your irrational numbers would be your pi, e, and some square roots

The answer is 160

Step-by-step explanation:

Comment

There really should be no answer to this. It sort of destroys the meaning of equality. However, you might be working in different bases. I'll assume that, but the base will be a fraction, which brings up other problems.

Solution

You have 5 17s there. So you will need five 32s. 5 * 32 = 160

The answer is 160

The area of a rectangle is 33 ft^2, and the length of the rectangle is 5 ft less than double the width. Find the dimensions of t
dimaraw [331]

Answer:

Length = 6

Width = 5.5

Step-by-step explanation:

Let's use the variable x to represent the width:

x = width

The question says that the length of the rectangle is "5 ft less than double the width". This length can be represented like this:

2x - 5 = length

To find the area of a rectangle, you multiply the width and length, so we are going to write an equation where we multiply the width and length and set it equal to 33 ft^2, which is the area:

(x)(2x - 5) = 33

Now use basic algebra to solve for x:

2x^2 - 5x = 33

2x^2 - 5x - 33 = 0

2x^2 + 6x - 11x - 33 = 0

(2x^2 + 6x) + (-11x - 33) = 0

2x(x + 3) - 11(x + 3) = 0

(2x - 11) (x + 3) = 0

x = 11/2, -3

x either equals 11/2 or -3. However, remember that x represents the width, and you can't have a negative number for a width, so x = 11/2 or 5.5.

Now plug in 5.5 to the length expression and simplify:

2(5.5) - 5

11 - 5 = 6

The length is 6 and the width is 5.5.

Hope this helps (●'◡'●)

Sara borrowed $5,000 from her father at a simple interest rate of 12.5% per year. Over a two - year period, she made equal month
Olin [163]

The formula for simple interest is:

A = P(1+rt)

Where P = amount borrowed

r = interest rate

t = time of loan


A = 5000(1 + 0.125*2)

A =6,250

The total amount she paid back was $6,250


For her monthly payment divide total paid back by 24 months ( 2 years = 24 months)


6250 / 24 = 260.42


Her monthly payment was $260.42
