To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.
Explanation:
200 = 200 Total Eggs
136 = 136 Eggs That Broke
So, the ratio of eggs that broke to total eggs is:
136 / 200
So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.
200 - 136 = 64
So now we know that, 64 eggs of 200 survived.
Which means, that 32% off the eggs had survived.
Answer:
x < -2
Step-by-step explanation:
Answer:
rate of the plane in still air is 33 miles per hour and the rate of the wind is 11 miles per hour
Step-by-step explanation:
We will make a table of the trip there and back using the formula distance = rate x time
d = r x t
there
back
The distance there and back is 264 miles, so we can split that in half and put each half under d:
d = r x t
there 132
back 132
It tells us that the trip there is with the wind and the trip back is against the wind:
d = r x t
there 132 = (r + w)
back 132 = (r - w)
Finally, the trip there took 3 hours and the trip back took 6:
d = r * t
there 132 = (r + w) * 3
back 132 = (r - w) * 6
There's the table. Using the distance formula we have 2 equations that result from that info:
132 = 3(r + w) and 132 = 6(r - w)
We are looking to solve for both r and w. We have 2 equations with 2 unknowns, so we will solve the first equation for r, sub that value for r into the second equation to solve for w:
132 = 3r + 3w and
132 - 3w = 3r so
44 - w = r. Subbing that into the second equation:
132 = 6(44 - w) - 6w and
132 = 264 - 6w - 6w and
-132 = -12w so
w = 11
Subbing w in to solve for r:
132 = 3r + 3(11) and
132 = 3r + 33 so
99 = 3r and
r = 33
To determine or predict the expected number of sales after 2 years, we substitute 2 to the t of the givne equation.
N = (8800)xln(7(2) + 9)
N = 27,592.34
Thus, it is expected that the number of sales after 2 years is 27,592 units.
14 pounds 9 ounces = 233 ounces
9 pounds 14 ounces = 158 ounces
233-158=75 ounces=4 pounds 11 ounces
