The sum of three primes is 18 so they must all be smaller than 18 as well.
Primes less than 18=2,3,5,7,11,13,17
2,3, and 13
2,5, and 11
There are two solutions...
We have that
1 1/2 acres-------------> 1.5 acres
one hour----------------> 60 minutes
Step 1
I proceed to make a rule of three
<span>if Jami can now mow 1/6 acre -----------------------> in 8 minutes
1.5 acres----------------------------------------------> X
X=1.5*8/(1/6)=72 minutes
72 minutes > 60 minutes
therefore
</span><span>Jami can not mow 1 1/2 acres in an hour
</span><span>The time required by jami to mow 1 1/2 acres is 72 minutes</span><span>
</span>
Answer:
B
Step-by-step explanation:
When you look at the triangle look at the 3 vertices. Now look at you answers given and choose one that combines all 3 vertices. You don't want your answer to contain a letter/number that represents the length of a side.
So in this case you don't want M or Y in you answer.
Your answer has to be made up of A X andT.
The only answer that uses AXT is answer B.
Answer:
Both are rational.
Step-by-step explanation:
As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.
And we know the product of two integers is an integer
p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.
Thus a+b and a-b is rational.
