The answer would be $24.55 per oz of gold alloy so rounded up would be $25
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.
Answer:
number 3
Step-by-step explanation:
(3,000+900+70) = 3,970
3,970*10 = 39,700
Answer:10x^2y^2
Step-by-step explanation:
5x2 X 2y2=10x^2y^2
Answer:
6√2
Step-by-step explanation:
Solving the given expression step by step:
72 = 2 × 2 × 2 × 3 × 3
Now for finding the square root we will make pair of two numbers of same values.
We have one pair of 2's and one pair of 3's and left one 2
Thus, √72 = 2 × 3 × √2 = 6√2
We rationalize denominator and change it into a simpler form as soon as possible.
