There are a certain number of hens and rabbits in a room. The number of feet of the hens exceeds the number of feet of the rabbits by 12, while the number of heads of the hens exceeds the number of the heads of the rabbits by 28. Then the number of hens and rabbits, respectively, in the room are:
Answer:
22 rabbits and 50 hens
Step-by-step explanation:
Let H and R stand for the numbers of Hens and Rabbits. Each hen has two feet and each rabbit has four feet. Each only has 1 head.
We can set the quantities of feet and heads:
Hens: 2H feet and 1H heads
Rabbits: 4R feet and 1R heads
We are told that:
1.) "The number of feet of the hens exceeds the number of feet of the rabbits by 12" Rewrite this as an expression:
2H - 4R = 12 [feet]
2) "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28" This is written as:
1H = 1R + 28 [heads]
Since each critter only has one head, this last expression will tell us, quickly, how many more Hens there are, which is 28. But by substituting the first expression (the feet) into the second, we can detrermine the exact number of each animal.
Rearrange 2H - 4R = 12 to isolate one of the variables. I'll choose H:
2H - 4R = 12
2H = 12 + 4R
H = (12 + 4R)/2
H = 6+2R
Now use this definition of H in the second equation:
1H = 1R + 28
1(6+2R) = 1R + 28
6 + 2R = 1R + 28
R = 22 There are 22 rabbits
Use this in the second equation to find the number of hens:
1H = 1R + 28
1H = 22 + 28
H = 50 There are 50 hens.
=================
Check:
1.) "The number of feet of the hens exceeds the number of feet of the rabbits by 12."
Hens have 100 feet total. Rabbits have 88 feet. The hens have 12 more total feet: This checks
2.) "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28"
There are 50 heans and 22 rabbits. The number of hen heads exceed the number of rabbit heads by 28. This also checks.

F. Line segment CD
Please hurry
The segments that could be the image of segment AB after a sequence of reflections, rotations, and/or translations include:
A. Line segment GH
D. Line segment NP
F. Line segment CD
What are the segment?From the information, the coordinates of the point A is (1, 2), the coordinates of the point B is (5, 2)
Therefore, the length of the line AB = 5 - 1 = 4 units
In this case, the transformations are, reflections, rotations, and/or translations which are rigid transformations, such that the length of the image of AB will be the same as the length of AB
Therefore, the possible images of AB are;
PN with coordinates P(5, -2) and N(9, -2) and length 9 - 5 = 4 units
HG with coordinates H(-4, -4) and G(-4, -8) and length -4 - (-8) = -4 + 8 = 4 units
CD with coordinates C(-4, 6) and D(-4, 2) and length 6 - 2 = 4 units

Which equation represents the transformation formed by vertically stretching the graph of f(x)=√ by a factor of 6 and then
vertically shifting the graph 7 units up?
O g(x) = √6x + 7
O g(x)=6√x+7
○ g(x)=√x+7
O g(x)=√√√x+7
Answer:
(b) g(x) = 6√x +7
Step-by-step explanation:
You want the equation of the square root function after it has been vertically stretched by a factor of 6 and translated up 7 units.
StretchA vertical stretch is accomplished by multiplying the function value by 'a', where 'a' is the vertical stretch factor. That means the stretched square root function will be ...
f(x) = √x . . . . original square root function
h(x) = 6·f(x) = 6√x . . . . . vertically stretched by a factor of 6
TranslationA translation upward is accomplished by adding the translation amount to the function value. The translated function will be ...
h(x) . . . . . original function
g(x) = h(x) +7 . . . . . translation upward by 7 units
Our stretched and translated function is ...
g(x) = 6√x +7

A cylindrical can with height 12 cm has capacity 600 mL. What is its radius, to the nearest millimetre? [Remember that 1 mL = 1 cm³.]
The required radius of the cylindrical can is 4 millimeters.
What is cylinder?A cylinder is a three-dimensional solid in mathematics that maintains, at a given distance, two parallel bases connected by a curving surface. These bases often have a circular form (like a circle), and a line segment known as the axis connects the centers of the two bases.
Given that,
The height of the cylinder h = 12 cm.
And volume of the cylinder v = 600 mL
Since, 1 mL = cm³
The volume v = 600 cm³.
Let radius of cylinder is r,
To find the radius, use formula,
Volume of cylinder V = π x r² x h
22/7 x r² x 12 = 600
22/7 x r² = 50
r² = 350 / 22
r² = 15.909
r = 3.98

express x² - 8x + 5 in the form {x-a]²-b where a and b are the integers
x² - 8x + 5 can be expressed as (x - 4)² - 11 in the form (x - a)² - b, where a = 4 and b = 11.
Let y = x² - 8x + 5 ..................( 1 )
Expanding (x - a)² - b we get,
x² - 2ax + a² - b ......................( 2 )
Equating ( 1 ) and (2), we get
x² - 8x + 5 = x² - 2ax + a² - b
Comparing the coefficient of x,
- 8 = - 2a
a = 4
Comparing constants,
a² - b = 5
since we know a = 4
4² - b = 5
16 - b = 5
b = 11
Hence x² - 8x + 5 = (x - 4)² - 11

How do you solve the following:
−3+ |n-2 | >5
Please help!!!!
Step-by-step explanation: To solve this inequality, we can first isolate the absolute value term on one side of the inequality by subtracting |n-2| from both sides of the inequality. This gives us the inequality -3 + |n-2| > 2. Then, we need to consider two cases: when |n-2| is positive and when |n-2| is negative.
If |n-2| is positive, then we can drop the absolute value bars and rewrite the inequality as -3 + (n-2) > 2. Solving this inequality, we find that n > 7.
If |n-2| is negative, then we must reverse the direction of the inequality because subtracting a negative number is the same as adding a positive number. This gives us the inequality -3 - (n-2) > 2. Solving this inequality, we find that n < -1.
Therefore, the solution to the inequality is the set of all numbers that are greater than 7 or less than -1, which is the interval (-1, 7).

What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
let's take the weight of five boys is x
so,
x/5 = 62
x = 310
and let's take the weight of four boys is y.
so,
y/4 = 64
y = 256
let's take the weight of a boy which is removed from them is z
so,
x - z = y
x - y = z
310 - 256 = z
z = 54
Hence, the mass of the boy removed is 54.

An ice cream shop sells a small bowl of ice cream for $2.25 and a large bowl for $3. One day, the shop sold 63 bowls of ice cream and made $159. How many of each size bowl did the shop sell?
The number of small size and large size bowls of ice cream sold in the shop is 40 and 22 respectively.
How to determine the number of each bowl size sold?let
Number of small bowl = x
Number of large bowl = y
x + y = 63
2.25x + 3y = 159
From (1)
x = 63 - y
Substitute into (2)
2.25x + 3y = 159
2.25(63 - y) + 3y = 159
141.75 - 2.25y + 3y = 159
- 2.25y + 3y = 159 - 141.75
0.75y = 17.25
divide both sides by 0.75
y = 17.25 / 0.75
y = 23
Substitute y = 23 into (1)
x + y = 63
x + 23 = 63
subtract 23 from both sides
x = 63 - 23
x = 40
In conclusion, The ice cream shop sold 40 small size bowls and 23 large size bowls
