Answer:

$0.20 per bagel

Step-by-step explanation:

subtract .69 from 7.89 to get 7.20. since there are 12 in a dozen, multiply 12 and 3 to get 36. divide 7.20 by 36 and you will get how much each bagel is, which is $0.20. Hope this helps :)

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f
IgorLugansk [536]
Use the equation of motion under gravity:-

s =  16t^2    where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 =  128.94 s

t = sqrt 128.94  =  11. 4 seconds to the nearest tenth of a second

Write the quadratic equation in factored form. x2 + x - 12 = 0
lapo4ka [179]

Answer:

(x + 4)(x - 3)

Step-by-step explanation:

x^2 + x - 12 = 0

In order to factorise an equation, one must take into consideration the factors of the values in given equation.

In the factored form, the above equation becomes

(x + 4)(x- 3)

Factors of x^2 = x times x

Factors of -12 = +4 x -3

As shown in the factored form above

WILL MARK THE CORRECT ANSWER BRAINLIEST!<br><br> Select all the correct answers:
stepladder [879]

Answer:

B, D

Step-by-step explanation:

Solve all equations:

A.

x-3x=-2x+4\\ \\-2x=-2x+4\\ \\0=4

This is false equality, so this equation has no solutions.

B.

x-\dfrac{1}{3}(3x)=0\\ \\x-x=0\\ \\0=0

This equality is true for all values of x, so this equation has infinitely many solutions.

C.

\dfrac{1}{3}x-3=4+2x\\ \\x-9=12+6x\\ \\x-6x=12+9\\ \\-5x=21\\ \\x=-\dfrac{21}{5}

This equation has the unique solution.

D.

3x+2-\dfrac{1}{3}(3x)=2+2x\\ \\9x+6-3x=6+6x\\ \\6x+6=6+6x\\ \\0=0

This equality is true for all values of x, so this equation has infinitely many solutions.

E.

x-\dfrac{1}{3}x+2=0\\ \\3x-x+6=0\\ \\2x=-6\\ \\x=-3

This equation has the unique solution.

A list of 8 numbers has a mean of 6. work out the total of the numbers.​
VARVARA [1.3K]

Answer:

48

Step-by-step explanation:

The mean of a number is the sum of all the numbers divided by how many numbers there are. We can set up this formula: mean = \frac{sum}{amountnumbers}.

When we plug our values into this equation, we get: 6 = \frac{sum}{8}. Solving this equation gets us sum = 6 * 8 = 48
