P = potato C = corn
3P + 4C = $40
5P + 2C = $34
Multiply -2 to the 2nd equation to get
-10P - 4C = -68
Add it to the 1st equation
3P + 4C = 40
-10P - 4C = -68
-----------------------
-7P = -28
Solve for P
P = $4
Substitute 4 into P(potato) to find what C(corn) is
You would time the denominator by 3 so 11*3 would be 33 then times the numerator by the same so 6*3 soot would be 18/33
I'm pretty sure the answer is SAS because it gives you one angle and the rest are sides
The empirical rule says that roughly 99.7% of the population is within 3 standard deviations of the mean.
Start at the center 60 which is the mean. Add on 3 standard deviations
60 + 3*4.5 = 73.5
and subtract off 3 standard deviations from the mean
60 - 3*4.5 = 46.5
So roughly 99.7% of the population of cattle has horn lengths between 46.5 inches and 73.5 inches
<h3>Answer: Choice D. 46.5 in - 73.5 in</h3>
108 miles 3 hours = 36 mph upstream
108 miles 2 hours = 54 mph downstream
bv = boat velocity in still water
cv = current velocity
bv -cv = 36
bv +cv = 54 Adding both equations
2*bv = 90
boat velocity in still water = 45 mph
since bv + cv = 54
then we know the current velocity = 9 mph
