132, 135, 138, 141, 144, 147, 150, 153, 156, 159, 162, 165, 168
Answer:
let cp be x
mp= x+ (20% 0f x)= 1.2x
sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x
profit = 40
sp-cp =40
1.02x-x=40
x=2000
cp =2000
mp= 1.2*2000=2400

Answer:
Step-by-step explanation:
they are opposite angles, so we put them equal to each other.
25.
6a+10= 130
6a=120 a=20 so now we plug it in 6(20) +10= 130
26. 4a-4=2a+30
2a=34 a=17 sso now we plug in 4(17)-4= 64 2(17)+30= 64
27. 6y+1=4y+9 2x-5=x+7
2y=8 x=2
y=4
now plug in 6(4)+1=25 4(4)+9=25 2(2)-5= -1 (2)+7=9

Step-by-step explanation:
Diego is correct they have to be similar
Answer:
A) x²/25 + y²/9 = 1
Step-by-step explanation:
The major axis length is the sum of distances to the foci from the ellipse, 10. So the semi-major axis has length 10/2 = 5. The foci are on the x-axis, so the ellipse is oriented horizontally.
The semi-minor axis is the other leg of the right triangle having the focus and center as one leg, and the semi-major axis as the hypotenuse. This is obviously a 3-4-5 triangle, so the semi-minor axis length is 3.
When the ellipse is horizontal, the formula for it is ...
... (x/(semi-major axis))² + (y/(semi-minor axis))² = 1
... (x/5)² + (y/3)² = 1
... x²/25 + y²/9 = 1
