Step-by-step explanation:
George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft. And then he continues on into making ten pieces that all are 6ft long before loading them onto his truck.
picture08
By looking at the different pieces of wood we can see that the following holds true.
60=30+30=6+6+6+6+6+6+6+6+6+6
This is called the reflexive property of equality and tells us that any quantity is equal to itself
a=a
We can also use this example with the pieces of wood to explain the symmetric property of equality. This property states that if quantity a equals quantity b, then b equals a.
ifa=b,thenb=a
Or if we use our example
if60=30+30,then30+30=60
Another property that can be explained by this is the transitive property of equality. It tells us that if a quantity a equals quantity b, and b equals the quantity, c, then a and c are equal as well.
ifa=bandb=c,thena=c
Or in the numbers taken from the oak tree example
if60=30+30
and30+30=6+6+6+6+6+6+6+6+6+6
then60=6+6+6+6+6+6+6+6+6+6
Since we know that 30 + 30 = 20 + 40 and that 30 + 30 = 60 we can substitute 30 + 30 for 20 + 40 and get 60 = 20 + 40. This is called the substitution property of equality.
If a = b, then a can be substituted for b in any expression.George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft.

equator?
Answers
Answer:
L = 24,873.6 miles
Step-by-step explanation:
Length of the Circumference
Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
[tex]L =2\pi\cdot r[/tex]
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:
[tex]L =2\pi\cdot 3,958.75\ miles[/tex]
L = 24,873.6 miles

A 60 square units
B 30 square units
C 16 square units
D 56 square units

Answer:B
Step-by-step explanation:
The answer is B because you 10*6 which is 60 then 60/2 is 30
The area of the parallelogram is 60 square units.
The correct answer is option (A)
What is parallelogram?
"It is a quadrilateral with opposite sides parallel and opposite angles equal"
What is the area of the parallelogram?"The area of the parallelogram is: A = base × height"
For given example,
the base of the parallelogram (b) = 6 units
the height of the parallelogram (h) = 10 units
Using the formula of the area of the parallelogram,
⇒ A = b × h
⇒ A = 6 × 10
⇒ A = 60 square units
Therefore, the area of the parallelogram is 60 square units.
The correct answer is option (A)

Answer:
Perimeter: 17 inches
Area: 8 square inches
Step-by-step explanation:
The ratio of perimeters is the same as the similarity ratio.
JKLM perimeter / ABCD perimeter = P/68 = 1/4
Multiplying by 68, we get ...
P = 68/4 = 17 . . . . inches
__
The ratio of areas is the square of the similarity ratio.
JKLM area / ABCD area = A/128 = (1/4)^2
Multiplying by 128, we get ...
A = 128/16 = 8 . . . . square inches
__
Perimeter = 17 inches
Area = 8 square inches
