Answer:
The blade covers an area of 235.714 square inches in one swipe
Step-by-step explanation:
In this question, we are to calculate the area that is covered by blade cover of the windshield wiper blade in 1 swipe.
To calculate this, we shall be using the formula for the area of the sector. The sector in this case subtends an angle of 120 degrees at the centre.
Mathematically, the area covered by the blade in one swipe is
A = θ/360 * pi * r^2
where θ = 120 degrees and r = 15 inch
A = 120/360 * 22/7 * 15^2
= 1/3 * 22/7 * 225 = 22 * 75/7 = 235.714 square inches
Answer:
1400
Step-by-step explanation:
it will be easier to first do 30 times 60, which is 180, then subtract the parts
the left up part is 100, the left bottom is 150, the top right is 150, added together, is 400
1800-400
The answer is (f * g) (x) = 12x
Since the x value can be changed to anything other than 4 (because then you would be dividing by 0 in x-4), the answer is: All real numbers except 4.
