Step-by-step explanation: Given a number N. Given two numbers X and Y, the task is to find the sum of all those numbers from 1 to N that are divisible by X or by ... Sn = (n/2) * {2*a + (n-1)* d} ... + (N / (X * Y) - 1) * (X * Y))/ 2;. return S1 + S2 - S3;. } // Driver code. int main().
hope this is right
Well you would have to fill in the bank so it would be 4000 and the answer would be 11,000 <span />
Answer:
36
Step-by-step explanation:
We must determine the x and y intercepts of the parabola:
When y=0, x=0 or x=10
WE know that the point of the triangle base is x and x+8. We can substitute this into the parabola equation because the endpoints are on the parabola.
f(x+8)![=-(x^2+16x+64)+10x+80](https://tex.z-dn.net/?f=%3D-%28x%5E2%2B16x%2B64%29%2B10x%2B80)
f(x+8)![=-x^2-6x+16](https://tex.z-dn.net/?f=%3D-x%5E2-6x%2B16)
f(x)=f(x+8)
![-x^2+10x=-x^2-6x+16](https://tex.z-dn.net/?f=-x%5E2%2B10x%3D-x%5E2-6x%2B16)
solve for x
![16x=16](https://tex.z-dn.net/?f=16x%3D16)
![x=1](https://tex.z-dn.net/?f=x%3D1)
Therefore the heigh is f(1):
![=-1^2+10=9](https://tex.z-dn.net/?f=%3D-1%5E2%2B10%3D9)
The area of the triangle is 1/2 base x height:
![=(1/2)\cdot{8}\cdot{9}=36](https://tex.z-dn.net/?f=%3D%281%2F2%29%5Ccdot%7B8%7D%5Ccdot%7B9%7D%3D36)

Answer:
- pancake: $0.50
- waffle: $1.20
Step-by-step explanation:
You can model the bills using w and p for the price of a waffle and pancake, respectively.
10w + 4p = 14
5w +8p = 10
Subtract half the first equation from the second:
(5w +8p) -(1/2)(10w +4p) = (10) -(1/2)(14)
6p = 3 . . . . . . . simplify
p = 0.50 . . . . . divide by 6
10w + 4(0.50) = 14 . . . . substitute into the first equation
10w = 12 . . . . . . . . . . . . subtract 2
w = 1.20 . . . . . . . . . . . . .divide by 10
A waffle costs $1.20; a pancake costs $0.50.
