Answer:
64
Step-by-step explanation:
2x(1/4 d)+d=96 (Rewrite the expression)
2x1/4d+d=96 (Reduce the numbers)
1/2d+d=96(Calculate)
3/2d=96 (Multiply both sides)
d=64
I think it’s B hope that helped
Hello.
It is the number that when you multiply it by itself gives 80. So, the square root of 9 is 3 since 3 x 3 = 9.
It’s not a whole number though, since 8 x 8 = 64 (too low) and 9 x 9 = 81 (close, but too high).
It is very close to 8.9442719099991587856366946749251, but it is known as a surd, and can not be written exactly as a decimal (it goes on forever, and doesn’t repeat) or a fraction.
Have a nice day
Answer:
<h2>C. <em>
20,160</em></h2>
Step-by-step explanation:
This question bothers on permutation since we are to select a some people out of a group of people and then arrange in a straight line. If r object are to be arranged in a straight line when selecting them from n pool of objects. This can be done in nPr number of ways.
nPr = n!/(n-r)!
Selection of 6 people out of 8 people can therefore be done in 8C6 number of ways.
8P6 = 8!/(8-6)!
8P6 = 8!/2!
8P6 = 8*7*6*5*4*3*2!/2!
8P6 = 8*7*6*5*4*3
8P6 = 56*360
8P6 = 20,160
<em>Hence this can be done in 20,160 number of ways</em>
