She has 4 groups all together. 3 groups with ten rocks each and 1 group with 8 rocks(8/10).
Answer:
Step-by-step explanation:
refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;
The factorial of an integer n is evaluated as;
Using this concept, the above expression can now be simplified as follows;
Therefore, the permutations of 5 items taken 3 at a time is 60.
The next expression, 
refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;
Therefore, the combinations of 6 items taken 4 at a time is 15.
The final step is to evaluate the product;
The marked price of the projector is $50,000.
<h3>What is the marked price?</h3>
The price of the projector after the discount can be represented with:
(100 - 10%)x - 90%x = 0.90x
Where x is the marked price
The price of the projector after the VAT is : (1.13) x 0.90x = 1.02x
Difference in price = 1.02x - 0.90x = 5850
0.12x = 5850
x = 5850 / 0.12
x = $50,000

Answer:
D on edge
Step-by-step explanation:

x^4+108x^3y^3+54x^2y^6+12xy^9+y^12 is the full extended form
So that means 54x^2y^6 is the answer
3y - x = 6 (Note: the formula for slope-intercept form is y = mx + b)
3y = x + 6 (moving the x over to separate both variables)
y = x/3 + 6/3 (after dividing both sides by 3)
y = x/3 + 2 (simplify)
Hope this helps! :)
