Prime numbers > than 5 are 7, 11, 13, 17, and 19 so 5/20, or 1/4, or 25% chance
Answer:
I am so sorry. I could only help for (a), model! The questions are not specific enough! SORRY!!!!
Are you sure that both a and b are zero?
I doubt it.
<span>-8a^8b^-2/10a^-4b^-10
should surely be written as a fraction for clarity:
</span><span>-8a^8b^-2
----------------- (at least this is how I interpret your question)
10a^-4b^-10
-8a^8 divided by 10a^(-4) comes out to (-8/10)a^12, and
b^(-2) divided by b^(-10) comes out to b^8
so that your final quotient is (-4/5)(a^12)(b^8).</span>
ANSWER: < T is congruent to < R
Answer:
The length of the page inside the margins=8 3/4 inches
Step-by-step explanation:
The total length of the year book can be expressed as;
L=l1+l2+l3
where;
L=Total length of yearbook
l1=top margin length
l2=inside margin length
l3=bottom margin length
In our case;
L=10 inches
l1=1/2 inches
l2=unknown
l3=3/4 inches
replacing;
10=(1/2)+l2+(3/4)
(1/2)+(3/4)+l2=10
(5/4)+l2=10
l2=(10)-(5/4)
l2=8 3/4 inches
The length of the page inside the margins=8 3/4 inches
