<h2>Answer:</h2>

The property that is illustrated by the equation is:

                   Associative property of multiplication      

<h2>Step-by-step explanation:</h2>

Associative property--

It states that the elements can be added or multiplied no matter in which order the elements are grouped.

i.e.

a+(b+c)=(a+b)+c

This is the associative property of addition.

and

a×(b×c)=(a×b)×c

This is the associative property of multiplication.

Commutative Property--

It states that two elements of the set when operated gives the resultant as the same when the two are operated in any order.

i.e.

a+b=b+a  This is commutative property of addition.

and

a×b=b×a This is the commutative property of multiplication.

Distributive Property--

Also, for any three elements a,b,c by the distributive property states that:

   a(b+c)=ab+ac

Here we have the equation as:

            2\times (\sqrt{8}\times 7)=(2\times \sqrt{8})\times 7

This is the associative property of multiplication.

The value of a certain rare stamp is 160% of its value three years ago if the stamp is worth $220 then what is it’s worth today
xz_007 [3.2K]

Answer:

572$

Step-by-step explanation:

100% of 220 is 220 so add them together. Then find 60 % of 220. To find 10% of a number move the decimal to the left one time. Which is 22. After that, multiply 22 by 6 because it's 60%. then ad 220+220+132=572.

Please help with this math question
nika2105 [10]
263.27 m^2

rectangle : 15 x 10 = 150 m^2
the half circle at the top has a diameter of 6m. therefore, it’s radius is 3m. if it is cut in half, the part removed from the triangle height is 3m. therefore, the height of the triangle is 35 -15 = 20; 20 - 3 = 17. the height of the triangle is 17. the triangle area formula is a = 1/2(bh).
a = 1/2 (10)(17)
a = 1/2 (170)
a = 85 m^2
the circle would be a = πr^2 but divided by 2 bc it’s a half circle
a = π(3)^2
a = π9
a = 28.27 m^2
150 + 85 + 28.27 = 263.27 m^2

Multiply 5/4 times 2/2. =. 10/8. -3/8

The difference is 7/8
