turkey? Express and explain your answer as a unit rate.
13/51 hours per pound
EXPLANATION
= 2 3/5 hours : 10 1/5 pound
= 13/5 hours : 51/5 pound
= 13/5 × 5/51 hours per pound
= 65/255 hours per pound

9) What 2 numbers have a total of 28 and a difference of 6?
Answer:
Sum: 17 + 11 = 28
Difference: 17 - 11 = 6
Step-by-step explanation:
The sum of x and y is 28. In other words, x plus y equals 28 and can be written as equation A:
x + y = 28
The difference between x and y is 6. In other words, x minus y equals 6 and can be written as equation B:
x - y = 6
Now solve equation B for x to get the revised equation B:
x - y = 6
x = 6 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 28
6 + y + y = 28
6 + 2y = 28
2y = 22
y = 11
Now we know y is 11. Which means that we can substitute y for 11 in equation A and solve for x:
x + y = 28
x + 11 = 28
X = 17
Summary: The sum of two numbers is 28 and their difference is 6. What are the two numbers? Answer: 17 and 11 as proven here:
Sum: 17 + 11 = 28
Difference: 17 - 11 = 6
Answer:
17 +11 = 28

Find the slope of the tangent line to the given polar curve at the point specified by the value of θ
r = 9 + 8 cos(θ), θ = π/3
The given curve has equation
r(θ) = 9 + 8 cos(θ)
and its derivative is
dr/dθ = -8 sin(θ)
When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.
Differentiate these with respect to θ :
dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)
dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)
In polar coordinates, we have
y(θ) = r(θ) sin(θ)
x(θ) = r(θ) cos(θ)
and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.
The slope of the tangent line to the curve is dy/dx. By the chain rule,
dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)
dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))
When θ = π/3, the slope is
dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))
dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))
dy/dx = - 1/(17√3)
So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is
y - 13√3/2 = -1/(17√3) (x - 13/2)
y = -(x - 338)/(17√3)
An isosceles triangle has two sides of equal lenght. The length of the third side is 1 ft less than twice the length of one of the equal sides find the length of each side when the perimeter is 23 ft, answer as a comma separated list
Answer: An isosceles triangle has two sides of equal length. The length of one of the equal sides is two more than 3 times the length of the third side. If the perimeter is 46m, find the length of each side.
Step-by-step explanation:
Hope this helps!
Answer:
Step-by-step explanation:
The perimeter is equal to the lengths of all the sides.
Let x equal the two sides that are equal to each other.
Then the 3rd side is 2x - 1 which is 2 times the length of the equal side minus 1.
So the perimeter 23 = x + x + (2x-1)
Now solve for x
23 = x + x + 2x - 1
add 1 to both sides
24 = x + x + 2x
24 = 4x
x = 6
The two equal sides would be 6 feet each
The other side would be 2(6) - 1 = 11
The perimeter is 6 + 6 + 11 = 23
Express 8 1/5% as a mixed number or a fraction
Please show work so I can understand it so I know what to do on problems that look like this in the future
Answer:
41/5
Step-by-step explanation:
First we change the 8 and 1/5% to 8.2%
Write the fraction down as a number over one = 8.2/1
Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
8.2/1 = (8.2 × 10)
(1 × 10) = 82/10
Reduce the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (82,10) = 2. So, (82÷2)/(10÷2) = 41/5 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 82/10 is also equal to 81/5 when expressed as a mixed number.

Step-by-step explanation:
Reflection across a line reverses the orientation of the figure from CW to CCW, or vice versa. Each point on the image is the same distance from the line of reflection as the corresponding point on the preimage.
These characteristics are manifested in figure A.
__
Figure B represents a translation to the right; Figure C represents both rotation and translation. Figure D is translation up and to the right.
_____
Additional comment
When vertices of a figure are labeled, their orientation (CW or CCW) is easy to identify. When they are not, it isn't always easy. It helps when the figure has no particular symmetry, as here. We can, for example, consider the sides in order from shortest to longest. That would make the orientation CCW on the left of figure A, and CW on the right. Figure A is the only figure in which the orientation changes.
CW=clockwise; CCW=counterclockwise

28. Suppose that the CPI in Year 1 is 150 and the CPI in Year 2 is 200. The rate of
inflation between Year 1 and Year 2 is:
a) 14.28%.
I b) 25%
c) 33.33%
d) 50%
The rate of inflation between year 1 and year 2, based on the CPI, is c. 33.33%.
The Consumer Price Index (CPI) allows us to calculate inflation. To find the inflation across these years, use the formula:
= (CPI₂ - CPI₁) / CPI₁ x 100%
Solving gives us:
= (200 - 150) / 150 x 100%
= 33.3%
In conclusion, the inflation is 33.3%.

find the center and radius of the circle whos equation is (x+5)^2+(y-3)^2=9
9514 1404 393
Answer:
center (-5, 3)
radius 3
Step-by-step explanation:
Compare the given equation to the standard form equation of a circle:
(x -h)² +(y -k)² = r² . . . . . . circle with center (h, k) and radius r
This shows us that ...
-h = +5 ⇒ h = -5
-k = -3 ⇒ k = 3
r² = 9 ⇒ r = √9 = 3
Then the circle center is (h, k) = (-5, 3), and the radius is r = 3.

The ages of three brothers are consecutive, even integers. If the sum of the first even integer, three times the second even integer and twice the third even integer is fifty. Find the ages of all three brothers
Answer:
The ages of all three brothers are 4,6,8 years.
Step-by-step explanation:
Here n is the smallest of the three consecutive even integers, the condition gives you this equation
2n + 3*(n+2) + (n+4) = 34.
2n + 3n + 6 + n + 4 = 34
6n = 24
n = 4.
Answer. The ages are 4, 6 and 8 years.
Hope this helps you.
The ages of the three brothers are 6, 8, and 10 years, respectively.
How to determine ages of the three brothersLet the ages of the three brothers be \(x\), \(x+2\), and \(x+4\).
The sum of the first even integer, three times the second even integer, and twice the third even integer is fifty:
\[x + 3(x+2) + 2(x+4) = 50\]
Simplify the equation:
\[x + 3x + 6 + 2x + 8 = 50\]
Combine like terms:
\[6x + 14 = 50\]
Subtract 14 from both sides:
\[6x = 36\]
Divide by 6:
\[x = 6\]
So, the ages of the three brothers are 6, 8, and 10 years, respectively.
