Answer:
50/30, 25/15, 10/6, 5/3
Step-by-step explanation:
To answer the question, you need to decompose the numerator and denominator into simple factors and see what combinations are possible.
50:2 = 25
25:5 = 5
5:5 = 1
Multipliers for 50: 2, 5, 5
30:2 = 15
15:3 = 5
5:5 = 1
Multipliers for 30: 2, 3, 5
Common multipliers for dogs and cats: 2 and 5
So we can divide the our ratio by 2, by 5 and by their product 2 x 5 = by 10.
We get the following series:

Given the function h(x)=-x²+4x+12, determine the average rate of change of the function over the interval -1≤x≤8
Step-by-step explanation:
the average rate of change is
(h(interval end) - h(interval begin)) /
(interval end - interval begin)
in our case this is
(h(8) - h(-1)) / (8 - -1) = (108 - 9) / 9 = 99/9 = 11/1 = 11
The bisector of one of the angles of a rectangle also bisects the side of a rectangle. Find the perimeter of the rectangle if you know that the shorter side of the rectangle is equal to 10 cm.
If the bisector of one of the angles of a rectangle also bisects the side of a rectangle. The perimeter of the rectangle if you know that the shorter side of the rectangle is equal to 10 cm is 60cm.
How to find the perimeter of the rectangle?If we look at triangle BCE, we will see that triangle BCE is isosceles based on the fact that both angles are equal to 45 degrees.
Hence,
BC = CE =10 cm
Lengths of the base and height = 20 and 10
Now let find the perimeter of the rectangle
Perimeter of the rectangle = 20 + 10+20+10
Perimeter of the rectangle = 60cm
Therefore the perimeter of the rectangle is 60cm.

The statements that are true about the reflectional symmetry of a regular heptagon are:
A heptagon is a type of shape.
A two-dimensional shape having seven sides and seven angles is called a heptagon. It is a member of the two-dimensional geometry polygon class. Polygons are closed geometric shapes with only straight edges. In Greek, "hepta" denotes seven, while "gonia" denotes an angle.
A line of symmetry will connect a vertex and a midpoint of an opposite side.
It has 7-fold symmetry.
A regular heptagon has 7-fold symmetry, which means that it can be divided into 7 identical parts by rotating it by 360/7 = 51.43 degrees. Since it has 7 sides, a line of symmetry will connect a vertex and a midpoint of an opposite side.
It has only 1 line of symmetry, and a line of symmetry will not connect 2 vertices or the midpoints of 2 opposite sides.

What is Y =- 2 on a graph?.
The equation y = -2 is represented on the graph as shown below :
Use the slope-intercept form to find the slope and y-intercept.
The slope, m, represents the steepness of a line. The slope of the line is also termed as gradient, sometimes. The y-intercept, b, of a line, represents the y-coordinate of the point where the graph of the line intersects the y-axis.
The slope-intercept form is
y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Find the values of m and b, using the slope-intercept equation.
y = -2
m = 0, b = -2.
The slope of this line = m = 0
The y-intercept = -2, therefore a point on the line = (0,-2)
Finding two points on the line:
(0,-2), (1,-2)
Thus, the equation y = -2 on graph is shown below.

How many degrees is a 360?.
The measure in degrees of the angle, the 1/360 of a circle is equals to one degree.
First note the following information: Degrees is an angular unit. The One rotation around the circle is equals to the 360 degrees. Angles measured in degrees always require the unit "degrees" after either a number or the degree symbol °. For example, 90 degrees = 90°. Rotation is 360 degrees, so angles greater than 360 degrees indicate more than a full rotation. The resulting direction that, when plotted on a circle, makes the endpoint of that angle the same as any other angle between 0 and 360 degrees. These angles are called coends. The arc should be proportional to the angle. The circle should be 360 degrees. Therefore, the degree of the angle is = 1/360 ( 360°) = 1 degree. From this we can conclude that the degree of the angle is 1 degree.

Daffynition decoder answers page 16. 7? hints are ozone and mistletoe from the punchline algebra book b
The answer for the Daffynition Decoder is 7.
The formula is O3 - M2 = 7. The calculation is to take the ozone (O3) and subtract the mistletoe (M2). O3 stands for ozone, which is composed of three atoms of oxygen and is represented by the number 3. M2 stands for mistletoe, which is composed of two atoms of oxygen and is represented by the number 2. The formula used to calculate the answer is m = 2o + 1, where m is the number of mistletoes and o is the number of ozones. The calculation is as follows: if there are 2 ozones, then the number of mistletoes is 2(2) + 1 = 5. Therefore, the answer is 7 (5 mistletoes and 2 ozones). This formula is useful for quickly calculating the total number of items when you know the number of each type of item.Therefore, if we subtract the mistletoe from the ozone, we get the answer of 7.

What is an example of a function that is its own inverse?.
One example of a function that is its own inverse is the square root function. The square root function takes a number and returns its inverse, which is always negative.
For example, the square root of 4 is equal to -2, and the square root of -3 is equal to 3. This means that you can multiply a number by -1 and then take the square root to get the same number as the original number. This proves that the inverse of a number is always a negative number. The opposite of a square is known as a rectangle. This shows that the square functions as its inverse. Another example of a function that is its own inverse is the exponential function. The exponential function takes two numbers and returns the reciprocal of their product. This means that the exponential function is also its own inverse because the reciprocal of a product is equal to the product of the reciprocals.
