Given:
[tex]\cos (55\dfrac{1}{2})^\circ\approx 0.566[/tex]
To find:
The angle, in degrees, that has a sine of approximately 0.566.
Solution:
We know that,
[tex]\sin(90^\circ-x)=\cos x[/tex]
We have,
[tex]\cos (55\dfrac{1}{2})^\circ\approx 0.566[/tex]
Using the above trigonometric identity, it can be written as:
[tex]\sin (90-55\dfrac{1}{2})^\circ\approx 0.566[/tex]
[tex]\sin (90-\dfrac{110+1}{2})^\circ\approx 0.566[/tex]
[tex]\sin (90-\dfrac{111}{2})^\circ\approx 0.566[/tex]
Taking LCM, we get
[tex]\sin (\dfrac{180-111}{2})^\circ\approx 0.566[/tex]
[tex]\sin (\dfrac{69}{2})^\circ\approx 0.566[/tex]
[tex]\sin (34\dfrac{1}{2})^\circ\approx 0.566[/tex]
Therefore, the angle [tex]34\dfrac{1}{2}[/tex] degrees has a sine of approximately 0.566.
If the radius of a sphere is doubled, by how many times has its volume been increased
Answer:
8 times larger than the original
Step-by-step explanation:
In any three dimensional object, cube sphere, cone, etc., if all of its dimensions increase by a factor of x then its volume increases by a factor of x³
In this case the dimensions double, so the volume increases by a factor of 2³ = 8

Cheese costs $1.80 per pound. Samira bought some cheese. She paid with a 5 dollar bill and got $1.40 in change. How many pounds of cheese did she buy?
Answer:
2 pounds of cheese
Step-by-step explanation:
First, we have to find out how much did she pay by taking
$5.00 - $1.40 = $3.60
So, she paid $3.60 in total. Then we find how many pounds of cheese she bought by taking
3.60 / 1.80 = 2 pounds of cheese
So, she bought 2 pounds of cheese.

Joe has 10 marbles . Ken has fewer marbles than joe witch inequality represent the number of marbles m that ken has
Answer:
k < 10
Step-by-step explanation:
An inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers.
Let k represent Ken. The closed side of < is the side the smaller number is going to be on. Ken has fewer marbles then Joe, therefore, k < 10 because Joe has 10 marbles.

Step-by-step explanation:
Gluten-free choices:
Main dishes: 4
Rice dishes: 7
Bread: 2 (40% of 5 is 2) 0.40 x 5 = 2
Multiply numbers of choices together: 4 x 7 x 2 = 56
There are a total of 112 meal deals.

What is an equation of the line that passes through the point (-5,-6) and is parallel to the line 4x−5y=35?
Answer: To find an equation of the line that passes through the point (-5,-6) and is parallel to the line 4x−5y=35, we can use the fact that two lines are parallel if and only if they have the same slope.
The slope of the line 4x−5y=35 is -4/5. Therefore, we can find an equation of the line that passes through (-5,-6) and is parallel to 4x−5y=35 by using the slope-intercept form of a linear equation, y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).
Substituting the values into the slope-intercept form, we get:
y = (-4/5)x + b
To find the value of b, we can substitute the coordinates of the point (-5,-6) into the equation:
-6 = (-4/5)(-5) + b
-6 = 8/5 + b
-6 - 8/5 = b
-24/5 = b
Therefore, the equation of the line that passes through the point (-5,-6) and is parallel to the line 4x−5y=35 is:
y = (-4/5)x - 24/5
This can also be written as:
y = -4/5x - 24/5

Which of the following is not true about cluster sampling?
Cluster sampling has the advantage of reducing sampling variability.
Cluster sampling has the advantage of saving time and money.
Cluster sampling uses clusters, which are miniature, nonoverlapping versions of the population.
Cluster sampling uses randomly selected clusters and samples everyone within each cluster.
answer is A
The option that is not true about cluster sampling is option A: Cluster sampling has the advantage of reducing sampling variability.
What is cluster sampling?
Cluster sampling often leads to larger sampling variability than other types of sampling methods, such as simple random sampling or stratified sampling, because clusters may not be a representative sample of the population and the individuals within a cluster may be more similar to each other than to individuals in other clusters.
Therefore, This increases the chance that the sample will not be representative of the population, which can result in a higher level of sampling error.

Pat is making rectangular placemats each with area 1200cm2 she wants to braid trim around the edges how much trim does pat need for the placemat
Pat needs 16[tex]\sqrt{1200}[/tex]cm of trim for each placemat to braid trim around the edges.
To find out how much trim Pat needs for each placemat, we need to first find the perimeter of the rectangle.
The area of the rectangle is given as 1200 [tex]cm^2[/tex].
The perimeter of the rectangle is the sum of all four sides of the rectangle. If the length and breadth of the rectangle are L and B respectively, then the perimeter P can be calculated using the formula:
P = 2(L+B)
Now, let's find the length and breadth of the rectangle using the area formula,
Area = LB = 1200 [tex]cm^2[/tex]
so LB = 1200 [tex]cm^2[/tex]
Now we can substitute the value of L and B in the perimeter formula
P = 2(L+B) = 2(sqrt(1200)+sqrt(1200))
As the area of the rectangle is given as 1200[tex]cm^2[/tex] , the length and breadth can be calculated as [tex]\sqrt{1200}[/tex]cm.
So the perimeter of the rectangle is
P = 2*([tex]\sqrt{1200}[/tex] + [tex]\sqrt{1200}[/tex])
= 2*2[tex]\sqrt{1200}[/tex]
= 4[tex]\sqrt{1200}[/tex]cm
To find the total length of trim Pat needs for the placemat, we need to multiply the perimeter by the number of edges that need a trim. Since the edges are around the rectangular placemat, so it will be 4 edges.
So, the total length of trim Pat needs for the placemat is
P4 = 4[tex]\sqrt{1200}[/tex]*4 = 16[tex]\sqrt{1200}[/tex]cm
So Pat needs 16[tex]\sqrt{1200}[/tex]cm of trim for each placemat.
