You can rewrite the decimal as a fraction and compare the two fractions. The fractions need to have a common denominator.

You can change the fraction to a decimal and compare. take the numerator and divide it by the denominator.

Unless I recognize the decimal as a fraction right away, I find it much easier to write the fraction as a decimal and compare

How many solutions exist for the system of equations graphed below?

Zinaida [17]

Answer:

one

Step-by-step explanation:

When a system of equations is graphed, the solution is the coordinate that is plotted at the intersection of the two lines.

If the two lines cross once, there is only one solution.

If the two lines are on top of each other then there are infinitely many solutions.

If the two lines are parallel ( and never touch ) then there are no solutions

By looking at the graph we notice the two lines intersect once. So we can conclude that there is only one solution.

Lucia flips a coin three times. What is the probability she gets (Head, tail, Head) in that order?

Svetach [21]

Answer: $\dfrac{1}{8}$

Step-by-step explanation:

The total outcomes of tossing a coin = 2

The total number of possible outcomes of flipping coin three times =2 x 2 x 2 = 8

Favorable outcome= (Head, tail, Head) in order

i.e. Number of Favorable outcomes = 1

We know that , Probability = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Therefore , The required probability $=\dfrac{1}{8}$

Hence , the probability she gets (Head, tail, Head) in that order $=\dfrac{1}{8}$

What would be the slope for (-4,-7) (-6,4)

Sliva [168]

Answer: $\frac{11}{-2}$

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

$\frac{y2-y1}{x2-x1} =$ m

so when using that formula with the cords, you get

$\frac{4-(-7)}{-6-(-4)}$

and then subtract everything and you'll get

$\frac{11}{-2}$

Which expression is equivalent to sqrt128x^5y^6/2x^7y^5 ? Assume x 0 and y > 0.

kolbaska11 [484]

<u>Answer:</u>

$\frac{8\sqrt{y} }{x}$

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

$\sqrt {\frac {128x^5y^6} {2x^7y^5} }$

To make it easier to solve, we can also write this expression as:

$\sqrt {\frac{128}{2} * \frac {x^5} {x^7} * \frac {y^6} {y^5}}$

Now we will cancel out the like terms to get:

$\sqrt {64*\frac{1} {x^2}*y }$

Taking the square root of the terms to get:

$8*\frac {1}{x} .\sqrt{y}$

$\frac{8\sqrt{y} }{x}$
