Answer:
1. 1.25
2. 0.8
Step-by-step explanation:
1. 2 : 2.5 = 1.25 Ratio from P To Q - 1 : 1.25
2. 2.5 : 2 = 0.8 Ratio from Q to P - 1 : 0.8
1. All you have to do is find the corresponding sides(meaning similar) and the compare them from one to another.
Example:
I know 5 and 4 are corresponding sides because they are similar. The ratio is Q to P we can find by writing them down. It can be written like this.
5:4 is so when we multiply this ratio from any side of Q we will get the correpoding side from P.
5:4 ratio = 1 : 0.8 - So the ratio is 0.8
There this is another ratio that we can compare to.
Now let’s say we need to find when the one of the P side is 4 and what would be the corresponding side.
4 x 1.25(ratio from P to Q) = 5
We can also find when the P side is 3 what would be Q’s corresponding side. Which is the ratio from P to Q or 1.25.
So just multiply 3 by 1.25.
3 x 1.25 = 3.75
3.75 x 0.8 = 3
Answer:
1
Step-by-step explanation:
-5 is 6 less than 1 so
-5 < 1
The cost of manufacturing 
units is
, where 
cost per unit and 
fixed cost.
Given that
Subtract the second equation from the second,
The variable cost per unit is 
.
Answer:
The number of people on the bus after the second stop is 8 less than the number of peoples on the bus before the 2:30 stop.
Step-by-step explanation:
Let 
be the total number of peoples on the bus before 2:30 stop.
For the first stop at 2:30:
The bus let off 13 people, so, the total number of remaining people on the bus 
again, the bus let on 8 people, so, the total number of people on the bus
For the second stop after 10 minutes (i.e at 2:40):
The bus let off 3 people, so, the total number of remaining people on the bus 
After the second stop, the number of people on the bus is 
, where P_0 number of peoples on the bus before 2:30 stop.
Hence, the number of people on the bus after the second stop is 8 less than the number of peoples on the bus before the 2:30 stop.
