v=vo+at;find a if v = 20, vo = 30, t =5.​

Answers

Answer:

-2 = a

Step-by-step explanation:

v = vo + at

20 = 30 + a5

now get the numbers and the variable on different sides

30 + a5 - 30 = a5

20 - 30 = -10

-10 = a5

now im going to divide each side by 5

a5 / 5 = a

-10 / 5 = -2

-2 = a

Step-by-step explanation:

[tex]V = V _{0} + at \\ 20 = 30 + a \times 5 \\ 5a = 20 - 30 \\ 5a = - 10 \\ \\ a = - \frac{10}{5} \\ \\ a = - 2[/tex]

Trevor has already run 26 miles on his own, and he expects to run 1 mile during each track practice. How many miles would Trevor have run after 24 track practices

Answers

If he has already one 26 miles and he is going to run 1 mile after 24 track practices he would have ran 50 miles

This is right because you would do : 26+24
And that equals 50
26+24=50

Move the numbers to the lines to order them from least to greatest

Answers

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

How can we express numbers belonging to decimal numeral system?

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

Lin divides the polynomial 2x^2 -4x+1 by 4 and gets 0.5x^2 -x + 0.25. is 0.5x^2 - x +0.25 a polynomial

Answers

Answer: yes

Step-by-step explanation:

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.
