Answer:
To Decrease an amount in a given Ratio, we need to multiply by a fraction that is less than one. For example, in scaling down a recipe for four people into a recipe for 3 people, we would use the ratio of 3 : 4 which means we would multiply all our recipe amounts.
Answer:
10 or 1000 in hundreds of units
Step-by-step explanation:
Given the supply curve of portable radio rentals:
and the demand curve for portable radio rentals:
we need to find the equilibrium of these two curves ( replace either's right hand side on the other's left hand side)
we have:
solving we have 
or 
in hundreds of units
Now the noise is equal to 3, therefore, we have to find the social supply curve by adding 3 to the first supply curve. following:
We find the intersection bewteen the social supply curve and the demand curve ( social equilibrium rental ):
Which gives 
or 
in hundreds of units.
Now that we integrated the noise into our considerations, the equilibrium rental exceeds the social equilibrium rental by 10 (50-40) (1000 in hundreds of units)
300=2×2×5×5×3
We observe that 2 and 5 are grouped in pairs and the 3 is left unpaired.
If we multiply 300 by the factor 3 then
300×3=2×2×5×5×3×3
900=2×2×5×5×3×3 which is a perfect square.
∴ Required number is 3
root of 900 =30

Answer:
answer 3:
They are proportion so just put equal sign and see if hey make sense.
Or you can realize that longer side of tringle for the 2 trangles are 10 and 5 and shorter side of triangle are 5 and 2.5 respectively
