Answer:
Sine, cosine and tangent formulas are used in RIGHT triangles. So you have one 90 degree angle and two acute angles that add up to 90 degrees (they are complimentary). So the cosine of one angle would be the same as the sine of the compliment to that angle... and vice versa. To answer this question, sin 81 = cos 9, since 81 and 9 are the two acute angles of the triangle and they both add up to 90 degrees. "Cos 9" is the answer when you wish to write "sin 81" in terms of "cosine."
Please give me brainiest
sine 81 degrees in terms of cosine is cos 9°
sin 81°
Trigonometric function:The angle is less than 90 degrees.it is an acute angle. Therefore, its in the first quadrant. The first quadrant, sine, cosine and tangent are positive.
sin 81° is less than 90 degree. Therefore, let's express them in terms of a cofunction.
Therefore,
sin x = cos(90 - x)
sin 81 = cos(90 - 81)
Therefore,
sin 81° = cos 9°

Find the area and perimeter of the polygons formed by the algebra tiles below: area: y X perimeter: 1 area: perimeter: 2
Answer:
The answer is below
Step-by-step explanation:
a)
The area of the figure = sum of the area of the individual polygons
The area of the figure = x + 1 + y + 1 + x = 2x + y + 2
The perimeter of the figure = sum of the length of the sides = 2(1 + (x + 1 + y + 1 + x)) = 2(2x + y + 3) = 4x + 2y + 6
b)
a)
The area of the figure = sum of the area of the individual polygons
The area of the figure = y² + xy + 1 + 1 + 1 = y² + xy + 3
The perimeter of the figure = sum of the length of the sides = (y + 1) + x + y + (y + 1) + y + 1 + 1 + 1 + x + 1 = 4y + 2x + 6

At the market Sydney put a few pairs in a bag then ways the bag on a product scale the bag pairs way 4.75 pounds she adds more pairs to the bag the new way of the bag is now 5.6 pounds right and solve an addition equation to find the weight of the pairs added to the bag?
Answer:
0.85 pounds
Step-by-step explanation:
We start with a bag that weighs 4.75 pounds and want to find the weight of the pairs added to the bag.
Let x equal the weight of the pairs added to the bag.
We can write an equation containing 4.75 pounds and x, and solve for x to find this weight value.
y = 4.75 + xWe know that the final weight of the bag is 5.6 pounds, so we can substitute this value for y.
5.6 = 4.75 + xSubtract 4.75 from both sides of the equation.
0.85 = xThe weight of the pairs added to the bag is 0.85 pounds.

Nicolas was testing
H0 : mu = 24
H0 : μ = 24
His test statistic was t = -1.79. Assume that the conditions for inference were met. What is the approximate P-value for Nicolas' test?
A. 0.0441.
B. 0.0505.
C. 0.0882.
D. 0.1010.
Answer:
B. 0.0505
Step-by-step explanation:
Test statistics technique is used to assess the condition whether to accept or reject the null hypothesis. Test statistics value is compared with the p-value in order to determine the status of null hypothesis. Nicolas test has t-value of 1.79 and degrees of freedom is assumed to be 11. The p-value for the Nicolas test is 0.0505.

D. 0.1010

What is the mean, median and mode of the data below. (List in that order: mean, median, mode) 18, 24, 20, 18, 21
Answer:
Mean: [tex]20.2[/tex], Median: [tex]20[/tex], Mode: [tex]18[/tex]
Step-by-step explanation:
The mean or average of a data set is calculating by dividing the sum of the data values by the number of the data values. In this case, the sum of the data values is [tex]18+24+20+18+21=101[/tex] and the number of data values is [tex]5[/tex], so the mean is [tex]\frac{101}{5}=20.2[/tex].
The median of a data set is the middle value when the data is ordered in ascending order, meaning least to greatest. Right now, the data is not in ascending order, but after ordering it, we get [tex]18,18,20,21,24[/tex]. Since there are [tex]5[/tex] data values in this set, the middle value, or median, will be the [tex]3[/tex]rd value, which, in this case, is [tex]20[/tex].
Finally, the mode of a data set is the most frequent value, or the value that shows up the most. In this case, [tex]18[/tex] shows up twice, unlike the other numbers, which only show up once, so we know that the mode is [tex]18[/tex]. Hope this helps!

Cameron is berry picking at the Berry Best farm. He wants to pick a total of 2 gallons of berries. After 30 minutes of picking, he has 6 pints of berries. For how many more minutes does Cameron need to pick berries to reach his goal?
Answer:
50 minutes
Step-by-step explanation:
2gal×4 qt in a gallon= 8 qt
8qt× 2pt in a qt= 16pt
16pt÷6 pt= 2.66
2.66×30= 80 min
80min-30min= 50 minutes
Jerome is a co-worker of a small company and received 1/3 of the company’s profits this year. What were the company’s overall profits if Jerome made 150,000? Type an equation and solve
Answer:
The company's overall profits were 450,000.
Step-by-step explanation:
We know that Jerome received 150,000. This 150,000 also counts as 1/3 of the profit, so if we put it as an equation, it gives us this:
1/3x = 150,000 We need to work out how much the overall profits are, which I've labelled as x.
x = 450,000 Here we multiply 150,000 by 3 to get x on its own, or you could also divide by 1/3.
I hope this makes sense to you. ^-^ If not, do let me know.
