Answer:

Step-by-step explanation:

In order to find the cost of the wallpaper per square foot, we must do 700.92 divided by the area of the wallpaper.

Area = length times width

Area of wallpaper = 12*9=108

700.92/108 = 700.92/108 = 6.49

The cost per a square foot is $6.49, so the answer is A.

Hope this helps :)

Answer:

Step-by-step explanation:

We are given that a and b are rational numbers where $b\neq0$ and x is irrational number .

We have to prove a+bx is irrational number by contradiction.

Supposition:let a+bx is a rational number then it can be written in $\frac{p}{q}$ form

$a+bx=\frac{p}{q}$ where $q\neq0$ where p and q are integers.

Proof: $a+bx=\frac{p}{q}$

After dividing p and q by common factor except 1 then we get

$a+bx=\frac{r}{s}$

r and s are coprime therefore, there is no common factor of r and s except 1.

$a+bx=\frac{r}{s}$ where r and s are integers.

$bx=\frac{r}{s}-a$

$x=\frac{\frac{r}{s}-a}{b}$

When we subtract one rational from other rational number then we get again a rational number and we divide one rational by other rational number then we get quotient number which is also rational.

Therefore, the number on the right hand of equal to is rational number but x is a irrational number .A rational number is not equal to an irrational number .Therefore, it is contradict by taking a+bx is a rational number .Hence, a+bx is an irrational number.

Conclusion: a+bx is an irrational number.

Ella and three friends run in a relay race that is 14 miles on each person runs equal parts of their race how many miles does ea

Lerok [7]

To find out how many miles does each person run, we can divide the total miles by 4 as each part is equal:

14÷4

=3.5miles

Each of them have to run 3.5 miles.

To prove the answer, we can multiply it by 4 to see if it is the original distance:

3.5 x 4

=14miles

Therefore 3.5 is the answer.

Hope it helps!
