Answer:

To solve fractions, you MUST HAVE THE SAME DENOMINATORS WHEN DEALING WITH ADDITION AND SUBTRACTION.

Step-by-step explanation:

For example, 2/3 + 3/6

The denominators in this case have a common denominator which is 6.

All you have to do is multiply the 2/3 by 2 in the numerator and the denominator. Once you do, you'll get 4/6 which you could then add to 3/6 to get 7/6 which would equal 1 1/6 or 7/6 either is fine.

Hope this helps! :)

Answer:

-3/2, 1.25, |-9/4|, 2.5, 121

Step-by-step explanation:

Convert all numbers to a decimal

-3/2 = -1.5

|-9/4| = 2.25

2.5 = 2.5

121 = 121.0

1.25 = 1.25

Now put them in order from least to greatest.

-3/2, 1.25, |-9/4|, 2.5, 121

The numbers to the lines to order from least to greatest; -3/2, 1.25, |-9/4|, 2.5, 121

Suppose that the number is abcd.efg and belongs to the decimal numerical system.

Remember one thing that the place on the left of decimal point is called ones. Move one-one places to right, and divide by 10 and 10 more and more.

Convert all the numbers to a decimal

-3/2 = -1.5

|-9/4| = 2.25

2.5 = 2.5

121 = 121.0

1.25 = 1.25

Now put them in order from least to greatest, we get;

-3/2, 1.25, |-9/4|, 2.5, 121

ok so first of all we can just change them to positive

54 / 9

this is what goes on in my head

the 2 digits equal 9

a number times 9 is just that number less then that number times 10

54 / 9 = 6

-54 / -9 = 6

The expression 0.50 x² - x + 0.25 is a polynomial.

It is given that Lin divides polynomial 2x² - 4x + 1 by 4 and gets 0.5x² - x + 0.25.

We have to find out that whether the expression given is a polynomial ?

What do you mean by a polynomial ?

Polynomials are algebraic expressions that consist of variables and coefficients e.g., polynomial with one variable is x² + x - 12.

As per the question ;

Lin divides polynomial 2x² - 4x + 1 by 4 and gets 0.5x² - x + 0.25

Let's check ;

(2x² - 4x + 1 ) ÷ 4

= [tex]\frac{2x^{2} }{4}[/tex] - [tex]\frac{4x}{4}[/tex] + [tex]\frac{1}{4}[/tex]

= [tex]\frac{x^{2}}{2}[/tex] - x + 0.25

or

= 0.50 x² - x + 0.25

or a form of polynomial i.e., ax² + bx + c.

Thus , the expression 0.50 x² - x + 0.25 is a polynomial.

Answer:

r=4.5% daily

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

[tex]P=P_o(1+r)^t[/tex]

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

We know after t=32 days, the population has increased by 309%. Being the original population P the 100%, then the population reached 309+100= 409%.

Substitute the given values into the model function:

[tex]409\%P_o=100\%P_o(1+r)^{32}[/tex]

Simplifying:

[tex]4.09=(1+r)^{32}[/tex]

We need to solve for r. Taking the 32nd root:

[tex]\sqrt[32]{4.09}=\sqrt[32]{(1+r)^{32}}[/tex]

Simplifying:

[tex]1+r=\sqrt[32]{4.09}=1.045[/tex]

Solving:

[tex]r=1.045-1\Rightarrow r=0.045[/tex]

r=4.5% daily
