Particles are not uniformly distributed in a heterogeneous mixture. A homogeneous mixture has a uniform composition with all components in a single phase, while a heterogeneous mixture has a non-uniform composition with components in at least two different phases
Cos pie divided by 12 in surd form
Answer:
¼(√6 + √2)
Step-by-step explanation:
We want to find cos (π/12) in surd form.
Now, cos (π/12) can be expressed as;
cos [(π/4) - (π/6)]
Now, from trig derivations we know that;
Cos (A - B) = CosACosB + sinAsinB
Thus;
cos [(π/4) - (π/6)] = cos(π/4)Cos(π/6) + sin(π/4)sin(π/6)
Now, in surd form;
cos(π/4) = sin(π/4) = (√2)/2
Cos(π/6) = (√3)/2
sin(π/6) = 1/2
Thus, Plugging in relevant values to get;
cos(π/4)Cos(π/6) + sin(π/4)sin(π/6) = ((√2)/2 × (√3)/2) + ((√2)/2 × 1/2)
This gives;
((√6)/4) + ((√2)/4) = ¼(√6 + √2)
Sarah and Jack go shopping Jack spends 20 percent of his money and Sarah spend 1/4 of her money how spends more
Answer:
Sarah, if each had the same amount of money to start with
Step-by-step explanation:
1/4=.25 or 25% 25%>20%
Sarah purchased 6 tons of sand $42.88 per ton and 7 cubic yards of mulch $28.58 per cubic yard. The state sales tax was 4.5%. What was the cash register receipt total?
Answer:
$477.92
Step-by-step explanation:
42.88 x 6= 257.28
28.58 x 7= 200.06
257.28+200.06=457.34
457.34 x .045= 20.58
20.58+457.34= 477.92

HOW I WILL GET A BRAINLIEST FROM THIS
"My friend here Justin, he's already taken, and he's cracked at Fortnite my guy.
I've been contemplating this video a ton of late. I've been considering the video since it gives a provocative message and keen editorial about enslavement and fixation.
To start with, we should take this word by word. The initial segment of the primary sentence; the principal shimmer of gold, is "My friend here Justin" An everyday sentence from the outset, however kindly recollect what I said, to arrive at the pot of gold at the focal point of the cavern of incongruity is justified, despite any trouble. This little portion of the sentence addresses that the storyteller has a companion named Justin. The principal word is possessive; my, and companion here addresses the kid before the camera is indeed Justin, showed by the storyteller naming Justin just after saying companion here. How the storyteller we never see, and even the way that we never see the storyteller entreats us to embed ourselves into them.
"He's taken" This passage is clear as crystal, aside from one section. "He" shows the subject of the sentence; Justin, is "now" demonstrating that Justin has as of now and is "taken". The virtuoso of this sentence is unpretentious yet significant pleasantry in "taken", as in the old style utilization of this sentence it would imply that Justin is associated with a sentimental or sexual relationship.
"Also, he's cracked at Fortnite" the biggest portion, consequently the one generally stuffed with significance, this selection is the zenith of the multitude of different passages of the sentence. "Also, expands on the last selection demonstrating this is the continuation of the story, and "He's cracked at Fortnite" is the star proclamation of this extract.
In general, this show-stopper addresses the narrative of a man's compulsion breaking him while fusing the absolute best incongruity and pleasantry I've ever seen, all done in one video, eight seconds, one sentence, and fourteen words.

around 571% or to be more exact, around 571.15384615%
Step-by-step explanation:
468 = 100%
2673 = ?
2673/468 = 297/52 = 5.71153846...≈5.7
468 * 2673/468 = 100%* 2673/468
2673 ≈571.15384615%

Please help need ASAP!
Answer: Approximately 49 degrees
A slightly more accurate angle value is about 49.458398 degrees.
======================================================
Explanation:
Draw a right triangle as shown in the diagram below. The horizontal leg is 13 ft and the hypotenuse is 20 ft. The angle between these two sides is what we want to find.
With this reference angle, the adjacent side is 13 and the hypotenuse is 20. We use the cosine ratio to tie the sides together with this angle.
Let x be the unknown angle.
cos(angle) = adjacent/hypotenuse
cos(x) = 13/20
cos(x) = 0.65
x = arccos(0.65)
x = 49.4583981264954
x = 49
I'm rounding to the nearest whole number since the given values (13 and 20) are also whole numbers. If your teacher provides other rounding instructions, then be sure to follow that of course.
The angle of elevation is roughly 49 degrees. Make sure your calculator is in degree mode. The notation "arccos" stands for "arccosine" and it's the same as inverse sine.

The length of a rectangle is 5 inches longer than it is wide. If the perimeter is 38 inches, what are the dimensions of the rectangle?
The width, or shorter side is ______
inches.
The length, or longer side is _____
inches.
Answer:
shorter side = 7 in
longer side = 12 in
Step-by-step explanation:
Let w = width
then w + 5 = length
The perimeter of the rectangle = 2 widths + 2 lengths.
So, w + w + w + 5 + w + 5 = 38 or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.
Now 4w + 10 = 38
4w = 28
w = 7
w + 5 = 7 + 5 = 12
shorter side = 7 in
longer side = 12 in
Check: 7 + 7 + 12 + 12 = 38 = perimeter
In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place? Drag and drop a fraction into the box to correctly complete the statement. The value of the 9 in the tenths place is Response area the value of the 9 in the hundredths place.
Answer:
the 9 in the tenths place is 10 times bigger than the one in the hundredths place
Step-by-step explanation:
The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.
What is the place value strategy?Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.
The decimal we are examining is 3.9928.
The 9 in tenth place has a value of 0.9.
The value of 9 in the hundredth place is 0.09
The fraction of the 9 in the tenth place is now the 9 in the hundredth place.
To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.
Mathematically, that would be;
0.09/0.9 = 0.1 = 1/10
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
So you can complete the statement by dragging and dropping "10 times" into the response area.

Which statement best describes an infinite geometric sequence?
a. The sequence contains a limited number of terms, and there is a common difference between the terms.
b. The sequence continues without end, and there is a common difference between the consecutive terms.
c. The sequence contains a limited number of terms, and there is a common ratio difference between the consecutive terms.
d. The sequence continues without end, and there is a common ratio between the consecutive terms.
The answer is D. The sequence continues without end, and there is a common ratio between the consecutive terms.
From the definition of an infinite geometric sequence, An infinite geometric series is the sum of an infinite geometric sequence . This series would have no last term.
