Answer: 3.41x10^3
Step-by-step explanation:
At the beginning of the year, we have:
R = 6.2x10 rats.
And we know that, in one year, each rat produces:
O = 5.5x10 offsprins.
Then each one of the 6.2x10 initial rats will produce 5.5x10 offsprings in one year, then after one year we have a total of:
(6.2x10)*(5.5x10) = (6.2*5.5)x(10*10) = 34.1x10^2
and we can write:
34.1 = 3.41x10
then: 34.1x10^2 = 3.41x10^3
So after one year, the average number of rats is: 3.41x10^3
Answer:
Step-by-step explanation:
If 2lbs costs $4.50, then most likely 1lbs would be half of what 2lbs cost.
So take $4.50÷2= $2.25
Then take the cost of 2lbs @ $4.50 then add the $2.25 (essentially the cost per pound) and 3lbs would cost $6.75.
<span>To link the displayed Wright flyer in the museum with the
actual plane, we have to calculate for the relation of the corresponding
parameter. In this problem, for both the display and the actual plane, we are
given with the length. Computing for the ratio gives us,</span>
<span>
ratio = length of the model / length of the actual plane
Length of the model = 35 cm</span>
<span>
We need to calculate for the length of the model in ft.</span>
<span>
length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
length of the model = 1.148 ft
</span>
<span>
</span>
<span>Going back to the calculation for the ratio,
ratio = (1.148 ft)/21 ft
ratio = 0.055
Therefore, the measurements used in the model is equal to 0.055 times the
actual dimensions.
Error may occur because of the number of significant figures measured for
rounding up or down of the answers after each calculation. </span>
