Answer:
First we multiply to see how many she has gotten, which is the equation 5x4 and that equals 20. Now we see how many she has lost. She has lost a total of six, we count this by subtracting 1/2 each time. The correct answer is 16.
Let me know if this helped, :-D
Answer:
Associative property of multiplication
Step-by-step explanation:
The associative property of multiplication.
The associative property says that the way in which factors are grouped in a multiplication problem does not change the product.
Lets solve the given expression.
(2x)(3y)(4z)=24xyz
According to associative property of multiplication you can write it as 2x(3y*4z)=(2x*3y)4z
Both the sides will give the same answer regardless of their order.
2x(12yz) =(6xy)4z
24xyz = 24xyz
Thus the answer is associative property of multiplication....
Answer:
A
Step-by-step explanation:
Answer: In a regular decagon, there are 10 lines of symmetry.
Step-by-step explanation:
Line of symmetry divides a figure into two equal halves so that if you flip the half image over the line of symmetry , the figure will look unchanged.
A regular decagon has 10 vertices and 10 edges.
To draw line of symmetry :
1.Draw lines to meet the exactly opposite point [shown by red color in the picture attached with the answer].
∴ 10 vertices will form 5 lines of symmetry.
2.Draw lines from the mid points of all the edges to the midpoint of the exactly opposite edge [shown by blue color in the picture attached with the answer].
∴ 10 edges will form 5 lines of symmetry.
⇒Total lines of symmetry in a decagon =5+5= 10
The answer is 48 (squared)
A = hb/2 = 8*12/2 = 48 (squared)
