Answer:
True
Step-by-step explanation:
l+w=20000
l=w+4000
w+4000+w=20000
2w+4000=20000
2w=16000
w=8000
l = 8000 +4000 = 12000
William scored 8000, Luca scored 12000
Answer: 5-2x=6-x, x= -1/3
Explanation:
“When I double it and subtract it from five it is the same as subtracting it from six”
So double means multiply by two, and the same as means equal. Use a variable to represent the number.
Therefore your equation is:
5-2x=6-x
So solving the equation would be:
-2x-x = 6-5
-3x = 1
x= -1/3
Answer:
68.8cm^2
Step-by-step explanation:
A trapezoid=h/2(b1+b2)
A trapezoid=6.4/2(12.9+8.6)
A trapezoid=3.2(21.5)
A trapezoid=68.8cm^2
Answer:
What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?
Should the speed limit be decreased on the highway connecting two large cities?
How many pedestrians would use a walkway built over a busy road?
Step-by-step explanation:
We use samples when using an entire population is not feasible.
It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.
Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.
On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
