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.

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.

what is the measure of angle JKL 70
Answer:
220°
Step-by-step explanation:
If you were to draw a line from points J and L to the center of the circle and call the center point O, angle JOL would be twice as much as angle JKL which is 140° according to a circle law. Since arc JL is 140°, arc JKL would be 220°, as an entire circle is 360°.

Tina likes to go on distance-learning steam she travels 60 K in 12 seconds what is the constant of proportionality
Answer:
5
Step-by-step explanation:
Given that:
60km in 12 seconds
Distance α time
Distance = k * time
K = constant of proportionality
Distance = 60 ; time = 12 seconds
60 = 12k
60/12 = 12k/12
5 = k
Constant of proportionality is 5

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

5(6p - 3) - 2 = 2(15p - 11) + 5
Answer:
p = 0
Step-by-step explanation:
step 1 (simplify) : 30p-17 = 30p-17 (add 17 to both sides)
step 2: 30p = 0 (divide both sides by 30)
p = 0

You can buy jars of the same jam in two sizes.
Large Jar
Small Jar
440g for £1.54
340g for £1.26
By considering the price per gram, work out
which jar is the best value for money.
Answer:
large jar
Step-by-step explanation:
large jar= £1.54 (divide) 440= 0.0035
small jar= £1.26 (divide) 340= 0.0037
as the large jar cost less (0.0035 > 0.0037) the large jar is the best value for money
