Which is greater 45/100 or 6/10? Explain.

20 pts! ^ ^ Please Answer Explaining it .. :l

Answers

6/10 is greater. If you made the number under the top number equal to 100, like the other one (45/100) you would get 60/100 which is greater than 45/100. You can make fractions larger like I did by multiplying both the top and bottom number by the same number, in this case 10

Answer:

6/10

Step-by-step explanation:

6/10 changed into denomination 100 is 60/100 which is larger than 45/100

Solve the following equation using the quadratic formulax^2-8x 97 = 0
The answer choices are in the picture

Answers

Answer:

Option B

$x=4+9i$ and $x=4-9i$

Step-by-step explanation:

we have

$x^(2) -8x+97=0$

The formula to solve a quadratic equation of the form $ax^(2) +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^(2)-4ac}} {2a}$

in this problem we have

$x^(2) -8x+97=0$

$a=1\nb=-8\nc=97$

substitute in the formula

$x=\frac{-(-8)(+/-)\sqrt{-8^(2)-4(1)(97)}} {2(1)}$

$x=\frac{8(+/-)√(-324)} {2}$

Remember that

$i^(2) =-1$

$i=√(-1)$

$x=\frac{8(+/-)18i} {2}$

$x=\frac{8(+)18i} {2}=4+9i$

$x=\frac{8(-)18i} {2}=4-9i$

Final answer:

To solve the equation x^2 - 8x + 97 = 0 using the quadratic formula, substitute the coefficients into the formula and simplify the expression. In this case, the equation has no real solutions.

Explanation:

To solve the equation x^2 - 8x + 97 = 0 using the quadratic formula, first identify the coefficients in the equation. The quadratic formula is given by x = (-b ± sqrt(b^2 - 4ac)) / (2a). In this case, a = 1, b = -8, and c = 97. Substitute these values into the quadratic formula and simplify the expression to find the value(s) of x.

Using the quadratic formula, we have x = (-(-8) ± sqrt((-8)^2 - 4(1)(97))) / (2(1)). Simplifying further, we get x = (8 ± sqrt(64 - 388)) / 2. Continuing the simplification, we have x = (8 ± sqrt(-324)) / 2. Since the square root of a negative number is not a real number, the equation has no real solutions.

Therefore, the answer is that there are no real solutions to the equation x^2 - 8x + 97 = 0.

Answers

the anwser is 3.0575.because 12.32 ÷4 equals 3.0575

Hi there, we divide 12.23 by 4. 12.23÷4=3.0575, So, each piece would weigh 3.0575

How would you graph the solution set of x - 6 < -3?

Answers

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-6 < -3$

Solve for x

Adds 6 both sides

$x-6+6 < -3+6$

$x < 3$

The solution is the interval (-∞,3)

All real numbers less than 3

In a number line the solution is the shaded area at left of x=3 (open circle)

The number 3 is not included in the solution
