1/2 2/4 3/6 What do you notice about the ratios?

Answers

if you were to simplify them, they would all equal 1/2
1/2=1/2
2/4=2/2 times 1/2=1 times 1/2
3/6=3/3 times 1/2=1/2
they all are ratios of 1 to 2

The first thing i noticed was that each ratio began from adding one each time. the second part began from the 2's table.
Also these ratios are equal ratios.
,Therefore 3 2 1
6 , 4 , 2 are all equal ratios

How and why does this equation -8-x=-3x equal x=4

Answers

because -8-(4)= -12, and -3(4) = -12

$- 8 - x = - 3x \n - 8 = - 3x + x \n - 8 = - 2x \n x = - ( - 8)/( - 2) = 4$
First, we add x to both sides and simplify. Then, we divide both sides by -2

Factor 3 from both terms:

3 (x² - 7)

To me, that's as far as you should need to go. But if you want to get
completely carried away, you could go one step further, since you have
the difference of two squares:

3 (x + √7) (x - √7)

Of course, there's no end now, because the last binomial could be
considered another difference of two squares, so you'd have to
factor that too:

3 (x + √7) (√x + ⁴√7) (√x - ⁴√7)

but to me, this would be nonsense.

$3x^2-21=3(x^2-7)=3[x^2-(\sqrt7)^2]=3(x-\sqrt7)(x+\sqrt7)$

One angle measure in an acute triangle is 38°. What could the measure of one of the other angles be?69°
95°
50°
27°

Answers

If is an acute triangle, all the angles should be acute angles.
180-38=142°
142-69=73°
So your answer is 69°, lovely~

One of the angles as your answer is 69 degrees

The Westerburg High School Soccer Team performs differently in the rain than they do when it doesn't rain. When it rains they have a 80% chance of winning, but when it doesn't rain they have a 50% chance of winning.Today there is a 60 % of rain. What is the chance that they win their game today?

A)48%B)50%C)52%D)68%

Answers

The correct answer is Choice D: 68%.

You have to make a tree diagram with all of the possibilities.

Here are the possibilities:

Rain - Win = 0.6 x 0.8 = 0.48
Rain - Loss = 0.6 x 0.2 = 0.12

No Rain - Win = 0.4 x 0.5 = 0.2
No Rain - Loss = 0.4 x 0.5 = 0.2

Adding up the two winning options gives us 68%
0.48 + 0.2 = 0.68
