Area is a metric concept that can allow a measurement to be assigned to the extent of a surface, expressed in mathematics as units of measurement called surface units.
Answer:
Computers R Us has a better price because it cost less at the same production rate.
Step-by-step explanation: to graph y=23.5x you just plug in numbers. If x = 1, 23.5 (1), which equals y. Now you can keep doing this to get up to 4. You may use a calculator if youd like.
Answer:
My answer would be y=2x+1
Step-by-step explanation:
Answer:
2(2y−7)(x+4)
Step-by-step explanation:
Factor 4xy−14x+16y−56
4xy−14x+16y−56
=2(2y−7)(x+4)
Answer:
20
Step-by-step explanation:
pilot flew a 400-mile flight in 2.5 hours flying into the wind . Flying the same rate and with the same wind speed, the return trip took only 2hours with a tailwind
The speed can be defined as the ratio distance over time, but in this case the pilot is flying at the speed of the plane as well of speed of the wind. We can denote speed of plane as "s" and speed of the wind as "k"
Then the speed of the plane=(s-k) this is because it is moving in the opposite direction of the wind.
But From the question, the plane distance=400mile and the corresponding time =2.5 h
Then the speed of the plane=(s-k) =400mile/2.5
=160mph
By the time it return from trip, the speed the plane flew with is (s+k) because the wind is at the rear.
From the question, the plane distance=400mile and the corresponding time =2 h
Then (s+k)= (400/2)
(s+k)=200mph
