Answer:
i dont see a question?
Step-by-step explanation:
First divide 6/20.
that gives you 3/10.
then multiply by five on the numerator and denominator.
that gets you 15/50.
so, he wins 15 games out of 50.
I hope this helped! :))
Represent the thickness of the frame by x. Framing the mirror will increase both its length and width by 2x. The area of the mirror with the frame is the product of the length and width which can mathematically be expressed as,
A = (3 + 2x)(2 +2x) = 8
The equation above can be simplified into 4x^2 + 10x -2 = 0. This equation can still be further simplified by dividing it by 2. However, it will give an answer which is not found on the choices. Thus, the answer is the third choice.
Answer:
2⅝
Step-by-step explanation:
You must convert each fraction to a <em>common denominator</em>.
The <em>least common multiple</em> of 2, 4, and 8 is 8.
1/4 +3/8 + 1/2 + 5/8 + 7/8 Convert to a common denominator
= 2/8 + 3/8 + 4/8 + 5/8 + 7/8
= (2 + 3 + 4 + 5 + 7)/8
= 21/8 Convert to a mixed number
= (16 + 5)/8
= 2 + ⅝
= 2⅝
Answer:
There are seven seventh roots of unity, e2πki7 , all on the unit circle, r=1 above.
The first one is at θ=2π7=360∘7=5137 ∘ , and there are others at 4π7,6π7,8π7,10π7,12π7 and of course at 0 radians, i.e. unity itself.
How to find?
There are 4 fourth roots of unity and they are 1, i,−1 and−i
Each of the roots of unity can be found by changing the value of k k k in the expression e 2 k π i / n e^{2k\pi i/n} e2kπi/n. By Euler's formula, e 2 π i = cos ( 2 π ) + i sin ( 2 π ) = 1.
