Answer:
The area of the lid = 24 cm²
Step-by-step explanation:
∵ The lid of the rectangular box is a rectangle
∵ The dimension of it is 6 cm and 4 cm
∵ Area of the rectangle = L × W
∴ The area of the lid = 6 × 4 = 24 cm²
Solution:
1) Switch +10 to -10 and subtract -10 in each side.
Example:
43-10= 33
2) You will be left with
3) Divide
4) Your final answer is -11
So, d = -11
Y = 4x - 3
y = mx + b
m = 4
b = -3
y intercept = (0,3)
(x,y) = (0,3)
(x,y) = (1,1) - substitute in ori equation
Answer:
It would take the plane about 4.17 hours to fly the whole round trip.
Step-by-step explanation:
Assuming that the distance from Chicago to Boston is 2000/2 = 1000 miles.
Since the wind is blowing from Chicago to Boston, when the plane is traveling to Boston, the velocity of the wind adds to the its velocity:
;
therefore, the time it takes for the plane to go from Chicago to Boston is
Now, as the plane flies back from Boston to Chicago, the wind is blowing opposite the direction of its movement; therefore, the wind's velocity subtracts from the velocity of the plane:
and the time taken during the trip is
Therefore, the total time taken during the whole round trip is
Therefore, on the windy day, it would take the plane 4.17 hours to fly the whole round trip
