This is one of those questions where, if you know the formula, it's easy,
and of you don't know the formula, there's no way.
In fact, the whole purpose of the question is to help you remember the formula.
The volume of a cylinder is
(pi) x (the radius)² x (the height).
For this particular cylinder, that's
(pi) x (3)² x (10) =
(pi) x (9) x (10) = 90 pi cubic units.
If you use (3.14) for (pi), then that's <em>282.6 cubic units</em>.
Answer: 81
To get this answer, you do two things
1) Take half of the x coefficient 18 to get 9
2) Square the result from the previous step to get 9^2 = 9*9 = 81
This value is added on to get x^2+18x+81 which factors to (x+9)^2 confirming we have a perfect square trinomial
money >= jeans + tshirts
65 >= 29 + 9* number of shirts
subtract 29 from each side
36> =9 *number of shirts
divide by 9 on each side
4 > =number of shirts
He can buy 4 or less shirts
Choice A
Answer:
0
Step-by-step explanation:
4 is an integer
-4is its additive inverse
4+-4=0
Answer:
I think 47 and 55
Explanation:
I think that each number is the previous one plus 8;
7+8=15
15+8=23
23+8=31
31+8=39
So, next will be:
39+8=47
47+8=55
Is this what ur looking for?? hope this help:)
