Area(S) = y×h
h = 10, area(S) = 160 mi²
160 = y×10
y = 16 mi
Answer: y = 16 mi
Answer:
Top one is 2x10+8x1+3x0.1
Step-by-step explanation:
Lizette ran for 1.25 hours and walked for 3 hours.
distance = speed × time
Her total distance is the sum of her distances at the different speeds. Let w represent her walking speed in mi/h. For distances in miles, speeds in miles per hour, and time in hours, the problem statement tells us ...
19 = (w+5)(1.25) + (w)(3)
19 = 4.25w + 6.25 . . . . collect terms
12.75 = 4.25w . . . . . . . subtract 6.25
3 = w . . . . . . . . . . . . . . . divide by 4.25
Lizette's walking speed is 3 mph.
Lizette's running speed is 8 mph.
The width would be 1/17 of an inch, approximately
That's a part of a circle that has a radius of 9 inches.
Area of any circle = (pi) x (radius)²
Area of the full circle that this is a piece of = (pi) x (9)² = (81 pi) square inches.
That's the whole circle. How much of the whole circle is in the picture ?
A whole circle has 360 degrees in the middle. This piece has 105 degrees in the middle.
This piece is ( 105/360 ) of the whole circle.
So the area of the piece is (105/360) x (81 pi) = <u>74.22 square inches</u> (rounded)
