Answer:
3 : 7 =>
Anna = $180
Raman = $420
1 : 4 =>
Anna = $120
Raman = $480
Step-by-step explanation:
<u>Shares when ratio is 3 : 7</u>
Anna : Raman = 3 : 7
Sum of ratio 10
Anna's share=
Raman 's share=
<u>Shares when ratio is 1 : 4</u>
Anna : Raman = 1 : 4
Sum of ratio = 5
Anna 's share =
Raman's share =
The point can be found as the weighted average of the given points, with the weights being the reverse of the line segment ratio values. The dividing point D will be
... D = (3*(4, 8) + 1*(14, 10))/(3 + 1) = (12+14, 24+10)/4
... D = (6 1/2, 8 1/2) . . . . . matches your second selection
Answer:
b x h
15 in x 12 in = 180in^2
the ^2 stands for inches square
Answer should be 60! hope this helps :)
Let's write x as our age and our cost as y -
If x≤5 , y=0
If 5<x≤12, y=10
If 12<x≤18, y=25
If x>18, y=35
It should be pretty straightforward to graph from there, but please ask if you're having any issues!
