The problem given above can be solved through the concept of permutation because of the importance of the arrangements. This may be solved through calculators directly by keying in,
10P5
That is, the permutation of 10 taken 5. The answer to this permutation is 30,240.
Step-by-step explanation:
(Ryan+ castel)/2
(5+6)/2

5.5 hrs or 5½ hrs
Answer: z = 264
Step-by-step explanation:
x to z = 16 to 176
x = 24 to ?
16/176 = 24/z
cross-multiply solve for z
z = 264
Answer:
Step-by-step explanation:
If the base of the square pyramid has an area of 576 units, then the side length must have a length of 
. 24/2=12, and using the pythagorean theorem you can find that the height of the pyramid is 
. Hope this helps!
To find the intersection points, you take x^2 - 4x + 9 = -2x + 17
This gives x^2 - 2x - 8 = 0,
which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2
From the graph, we can see that x is positive, meaning x = 4, so a = 4.
Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.
a + b = 4 + 9 = 13. The answer is B.
