Is using the associative property of addition a good strategy for simplifying (4/3 + 2/3) + 2? Why or why not?

Kitty [74]

Answer:

I say yes because when u solve it and flip the ( )'s, you get the same answer.

Step-by-step explanation:

Work:

(4/3 + 2/3) + 2

6/3 + 2

2 + 2

= 4

4/3 + (2/3 + 2)

4/3 + 8/3

12/3

= 4

Hope this helps!!

Answer:

0.21

Step-by-step explanation:

The given expression is :

$0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}$

We need to solve it.

We know that,

$\sqrt{0.09}=0.3\ and\ \sqrt{0.05}=0.223$

So,

$0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}=0.5\times 0.3-2\times 0.22+0.5\\\\=0.21$

$=\dfrac{21}{100}$

So, the value of the given expression is equal to 0.21.

Which equation represents the line that is perpendicular to y = 5 and passes through (-4,-3)?

kenny6666 [7]

Answer:

The required equation is: y=-3

Option D is correct.

Step-by-step explanation:

We need to write equation of line that is perpendicular to y = 5 and passes through (-4,-3).

The equation of line in slope-intercept form is expressed as: $y=mx+b$

where m is slope and b is y-intercept.

Finding Slope:

Comparing with the given equation y=5, the slope m =0

The slope of required line will be opposite reciprocal of 0 as both lines are perpendicular. so it will be m=0

Finding y-intercept

The y-intercept can be found using slope m=0 and point (-4,-3)

$y=mx+b\\-3=0(-4)+b\\b=-3$

So, y-intercept b is b=-3

The equation of required line having slope m=0 and y-intercept b=-3 is

$y=mx+b\\y=0(x)-3\\y=-3$

So, required equation is: y=-3

Option D is correct.

Danny poured 78 l of water into containers xy and z. the ratio of the volume of water in container x to the volume of water in c

Paladinen [302]

The ratio of x:y:z = 20:8:11

Total unit = 20+8+11 = 39

Value of 1 unit ratio = 78/39 = 2

So, the water in container X, 20(2) = 40 liters

Your answer is 40 liters
