Which property states that the order of the addends does not affect the sum? commutative property of addition reflexive property
Nonamiya [84]

Answer:

Commutative property

Step-by-step explanation:

  • Commutative property states that no matter how the addens are placed, the result of the operation (sum) remains the same.
  • For <u>example</u>, given three numbers a, b and c, the result of a+b+c=b+c+a=a+c+b.
  • Then, when you are solving a sum, the order of the elements does not matter. If we want to see this numerically, with an other example: 4+5=5+4=9.

Answer:

126 square units

Step-by-step explanation:

Area of section 1 is 8 square units which is triangle and,

Area of triangle is =  \frac{1}{2}\times b\times h

b= 2 units and height =8 units

So,

Area of section 1  =  \frac{1}{2}\times 2\times 8=8 \quad\text{ square units}

Same Area is of section 2 which is also a triangle and has same base and height.

So,

Area of Section 2 = \frac{1}{2}\times 2\times 8=8 \quad\text{ square units}

Now the Area of section 3 which is square with side of 10 units

So,

Area of section 3 =  a^{2} =10\times10=100\quad \text{square units}

Total Area of Trapezoid = 8+8+100=126 \quad \text{square units}

How many 1 5 s are in 9?
expeople1 [14]

Answer:

45

Step-by-step explanation:

To know how many 1/5 s are in 9, we will take the ratio of both numbers as shown;

9:1/5

= 9 ÷ 1/5

= 9 * 5/1

= 9 * 5

= 45

Hence there are 45 1/5s in 9
