Answer:
Step-by-step explanation:
a1=2/3
sequence is 2/3,3/4,4/5,...
for numerator a1=2
d=3-2=1
numerator of nth term=a1+(n-1)d=2+(n-1)×1=2+n-1=n+1
denominator = 1 more than numerator=n+1+1=n+2
so an=(n+1)/(n+2)
or for denominator a1=3,d=4-3=1
denominator of nth term=3+(n-1)×1=3+n-1=n+2
an=(n+1)/(n+2)
Answer:
C
Step-by-step explanation:
10×-28=-280
35-8=27
35×(-8)=-280
10x²+27x-28
=10x²+(35-8) x-28
=10x²+35x-8x-28
=5x(2x+7)-4(2x+7)
=(2x+7)(5x-4)
Answer:
10%
Step-by-step explanation:
The total population of students will be equal to the sum of both those who wore the silly hat and those who didn't hence
Total students= 74+666=740
Number of students who wore silly hat is given as 74 hence when expressed as a percentage of the total students' population we get that
percentage of the students wore a silly hat=
Therefore, 10% of students wore a silly hat last Tuesday
I think it should be 6.5 inch but I'm not positive.
I hope this helps! :))
