Convert 10 centimeters into yards. Round your answer to the nearest hundredth.
Answer:
0.11 yards
Step-by-step explanation:
To convert centimeters to yards, find the needed unit conversions:
[tex]cm(\frac{in}{cm})(\frac{ft}{in})(\frac{yd}{ft})[/tex]
Convert centimeters to inches, inches to feet, then feet to yards!
Now replace the values with the correct quantities:
[tex]10cm(\frac{1in}{2.54cm})(\frac{1 ft}{12 in})(\frac{1 yd}{3 ft})[/tex]
Finally, simplify and cross-cancel the units:
[tex]0.10936... yd[/tex]
Round to the nearest hundredth:
[tex]0.11 yd[/tex]
Which mapping represents a rotation of 270 degrees clockwise about the origin?
The mapping representing a rotation of 270 degree clockwise about the origin is (x, y) -----> (-y, x)
We use the rotation of 90 degree to find the mapping of 270 degrees.
The rotation of 270 degree clockwise is same as the anticlockwise rotation of 90 degrees about the origin.
So the mapping of 270 degree clockwise rotation is exactly the mapping of 90 degree anti clockwise rotation.
Now the mapping of 90 degree anti clockwise rotation is (x, y) -----> (-y, x).
So the mapping representing a rotation of 270 degree clockwise about the origin is (x, y) -----> (-y, x)
This implies that a point (x, y) on the co-ordinate plane becomes (-y, x) after a clockwise 270 degree rotation.

A can of Campbell's soup has a diameter of 4 inches and a height of 6 inches.
What is the volume of the soup in the can?
Answer: V = 75.4
Step-by-step explanation: Assuming this is a cylinder we can use the formula πr^2*h. All we have to do is plug in the numbers for the equation. Since we know radius is half of the diameter we can set radius to 2. h represents height.
So since the formula is saying we need to square the radius. We multiply 2*2=4
We can then plug this in for r squared.
Making our equation= π*4*6 = 75.4

Gavin is selling water bottles at a baseball game to help raise money for new uniforms. Before the game, he buys 48 water bottles for a total of $18.50. At the game, he sells all of the bottles for $1.25 each. How much profit does Gavin make?
$
Answer: $41.50 41 dollars and 50 cents in profit
Step-by-step explanation:
First, 1.25x48=60
Second, 60-18.50=41.50
Answer:
$41.50
Step-by-step explanation:
So we know that Gavin bought 48 water bottles before the game for $18.50. We also know that he sold the water bottles for $1.25 each.
If we want to know how much profit he made, we first have to find the amount of money he received.
To find this, we need to multiply the number of water bottles by the price for each bottle;
48 × $1.25
This gives us a total of $60.
Now to find the profit, we have to subtract the amount he paid for the water bottles by the total he made;
$60 - $18.50
This means he made a profit of $41.50.

A pool measuring 18 meters by 20 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the
path combined is 1520 square meters, what is the width of the path?
18
20
20+ 2x
18+2x
By solving a quadratic equation we can see that the width of the path measures 20 meters.
How to find the width of the path?
We know that the pool measures 18 meters by 20 meters, then the area of the pool alone is:
A = 18m*20m = 360 m^2
Now, if the path has a width x, then the rectangle that includes the path and the pool has dimensions:
(18m + 2x) and (20m + 2x)
And its area is given by:
(18m + 2x)*(20m + 2x)
And we know it is equal to 1520 m^2, then (i'm not writting the units in the computation):
(18 + 2x)*(20 + 2x) = 1520
360 + 4x^2 + 76x = 1520
Now we just need to solve that quadratic equation:
4x^2 + 76x - 1520 + 360 = 0
4x^2 + 76x - 1160 = 0
The solutions are:
x = (-76 ± √(76^2 - 4*4*(-1160))/(2*4)
x = (-76 ± 156)/4
We only care for the positive solution, which gives:
x = (-76 + 156)/4 = 20
We conclude that the width of the path measures 20 meters.

cluster sampling is the type of sampling is used.
What do you mean by cluster sampling?In cluster sampling, a population is divided into clusters, which are smaller groups. They then choose a sample at random from these clusters. Often employed to investigate huge populations, particularly those that are extensively geographically distributed, cluster sampling is a probability sampling technique. Typically, clusters used by researchers are already-existing groups like cities or schools. Clusters are frequently more homogeneous than the population as a whole since they are typically naturally occurring groups, such as schools, cities, or houses. When conducting your study, you should be aware of this as it might compromise the validity of your findings.

the shorter leg of a right triangle is 8 less than the hypotenuse. the longer leg is one less than the hypotenuse. find the perimeter
The perimeter of the right triangle is 30 units.
How to find the perimeter of a right triangle?The shorter leg of the right triangle is 8 less than the hypotenuse. The longer leg is one less than the hypotenuse.
Let's break the information into smaller chunk.
The shorter leg of a right triangle is 8 less than the hypotenuse.
The longer leg is one less than the hypotenuse.
The hypotenuse is the longest side of a right triangle.
Therefore,
let
the hypotenuse = x
short leg = x - 8
long leg = x - 1
Applying Pythagorean theorem in the given right triangle.
c² = a² + b²
where
c = hypotenusea and b are the other legs.(x - 1)² + (x - 8)² = x²
(x - 1)(x - 1) + (x - 8)(x - 8) = x²
x² - x - x + 1 + x² - 8x - 8x + 64 = x²
2x² - 18x + 65 = x²
x² - 18x + 65 = 0
(x - 13)(x - 5) = 0
Therefore,
x = 5 and x = 13
13² - 5² = a²
169 - 25 = a²
a = √144
a = 12

A print shop borrows $5700 from a credit union for 193 days. The credit union charges simple interest at an annual rate of 12% for this loan. Assume 1/365 each day is
of a year. Answer each part below.
Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas.
The amount borrowed by the print shop: $5700
Time for which loan is taken: 193 days
Rate of interest: 12%
Day in terms of year is given by: 1/365
The formula for simple interest:
Simple interest = P*R*T/100
where P = principal amount invested
R = rate of interest
T = time in years
Solving the question using the formula we have:
Simple interest = (5700*12*193)/(100*365)
= 13201200/36500
= 361.67 or $362
Interest that will be owed after 193 days will be $362
Amount owed after 193 days will be $5700 + $362 = $6062

The dimensions of the rug which Abdul would use in discuss as described in the task content are; 21.84 ft by 21.84 ft.
What are the dimensions of the rug rounded to the nearest hundredth?It follows from the task content that the dimensions of the rug which Abdul would use in the room in discuss are to be determined.
Since the room Abdul wants to put a rug on is; 775 ft² and the room is a square room.
It follows that all sides of the room are equal and the length of each side can be determined as;
s = √Area; since Area = s².
s = √775
s = 27.839 ft.
Hence, the dimensions of the room is; 27.839 ft by 27.839 ft.
However, since he wants to leave a 3-foot border of bare floor on each side, it follows that the dimensions of the rug on each axis would be;
= 27.839 - 3 -3 = 21.839 ft on all sides.
