Step-by-step explanation:
295 (miles to drive altogether) - 115 (miles already driven) = 180 (miles left to drive)
115 (miles already driven) / 2 (how many hours it took to reach 115 miles) = 57.5 (miles per hour)
180 (miles left to drive) / 57.5 (miles per hour) = 3.13 (hours it will take to reach the 295-mile mark at a rate of speed of 57.5 miles per hour)
So, you will have to drive more miles per hour than 57.5 miles per hour to be able reach the 295-mile goal, because it would take approximately 3 hours to drive the remaining 180 miles.
You will have to drive AT LEAST 72 miles each hour, and then 36 miles in the half hour to be able to reach the 295-mile mark.
I hope this helps, and is a thorough enough explanation :)
Answer:
Length of the rectangle is = 8 inches.
Step-by-step explanation:
Given :
Area of square = Area of the rectangle
According to the question:
Length of the square be 'x'.
Its area = (Side)*(Side) = ...equation (i)
Length of the rectangle =
Width of the rectangle =
Area of the rectangle =Length * Width
⇒
⇒ ...equation (ii)
Equating both the equation as area of both the figure are equal.
⇒
⇒ ...subtracting both sides
⇒ ...dividing both sides with 2
⇒ inches
Plugging the value of x=4 in the length of the rectangle.
We have,
⇒
So the length of the rectangle = 8 inches.
Answer:
64k^2 - 16k +1
Step-by-step explanation:
We can rewrite this as
(-8k+1) ^2
We know that (a+b)^2 = a^2 +2ab +b^2
Let a = -8k and b = 1
(-8k+1) = (-8k)^2 +2*(-8k)(1) + 1^2
=64k^2 - 16k +1
